BIS ISI Certification for Furniture in India: Furniture QCO 2025, IS 17631 to IS 17636 and the Complete Licensing Process

Furniture has joined the list of products that cannot be manufactured, imported, stored, or sold in India without the ISI mark. With the Furniture (Quality Control) Order, 2025 — notified by the Department for Promotion of Industry and Internal Trade (DPIIT) vide S.O. 801(E) dated 13 February 2025 — six major furniture categories now fall under compulsory BIS certification under Scheme-I of the BIS (Conformity Assessment) Regulations, 2018, the same ISI Mark Scheme that governs cement, steel, and household electrical goods on the BIS list of products under compulsory certification. The change is significant for an industry that has historically operated with minimal regulatory oversight. India’s furniture market — spanning large organised manufacturers, thousands of MSME workshops, importers of ready-to-assemble furniture, and global brands selling through e-commerce — must now demonstrate conformity to Indian Standards IS 17631 through IS 17636 before placing covered products on the market. For general and large enterprises the obligation is already in force since 14 February 2026; micro and small enterprises must comply by 14 August 2026. This guide explains which products are covered, the applicable standards, the step-by-step ISI licensing process, documents, timelines, common mistakes, and how furniture certification fits into the wider India compliance picture. Why Furniture Now Falls Under Mandatory BIS Certification Quality Control Orders are the government’s instrument for making an Indian Standard mandatory. Once a QCO is notified under the BIS Act, 2016, no person can manufacture, import, distribute, sell, hire, lease, store, or exhibit for sale any covered product without the Standard Mark — the ISI mark — granted under a valid BIS licence. The Furniture QCO 2025 follows the same template the government has applied to footwear, toys, and kitchen appliances: raise the quality floor of the domestic market, curb the inflow of substandard imports, and align Indian products with international quality benchmarks. The safety rationale is real. Chairs that collapse under load, bunk beds with entrapment gaps, storage units that tip over onto children, and tables with unstable structures cause injuries that standardised testing is designed to prevent. The furniture standards evaluate stability, structural strength, durability under repeated use, and surface safety — hazards that are invisible at the point of sale but critical over a product’s life. For manufacturers, the QCO is also a commercial gate: institutional buyers, government procurement, organised retail, and e-commerce marketplaces now verify BIS licences for covered furniture, and customs authorities check compliance at import. Which Furniture Products Are Covered: IS 17631 to IS 17636 The Furniture QCO 2025 covers six product categories, each mapped to a dedicated Indian Standard published in 2022: Indian Standard Product Category Typical Products Covered IS 17631:2022 Work Chairs Office chairs, task chairs, swivel chairs, ergonomic desk chairs IS 17632:2022 General Purpose Chairs and Stools Dining chairs, visitor chairs, plastic moulded chairs, stools IS 17633:2022 Tables and Desks Office desks, dining tables, study tables, workstations IS 17634:2022 Storage Units Wardrobes, cabinets, bookshelves, filing cabinets, cupboards IS 17635:2022 Beds Single and double beds, fully assembled and ready-to-assemble cots IS 17636:2022 Bunk Beds Bunk beds and loft beds for domestic and institutional use The standards are material-agnostic in scope — wood, metal, plastic, and combination constructions are all covered when the product falls within a listed category. Ready-to-assemble (RTA) and knock-down furniture, the dominant format for imports and e-commerce, is explicitly within scope for beds and other categories. Manufacturers should confirm the exact applicability of each standard and its current edition against the latest BIS notification before testing, because the licence is granted per standard, per manufacturing location. Who Must Comply — and By When The QCO binds every link in the supply chain. Indian manufacturers of covered furniture need a BIS licence under Scheme-I for each manufacturing premises and each applicable standard. Importers cannot clear covered furniture through customs unless the foreign manufacturing site itself holds a BIS licence — obtained through the Foreign Manufacturers Certification Scheme (FMCS), under which BIS audits the overseas factory and grants the ISI licence to the foreign entity, which must also appoint an Authorised Indian Representative (AIR). Traders, distributors, and marketplaces are equally barred from storing or selling non-compliant stock. The enforcement calendar is staggered by enterprise size: The MSE deadline is now days away. A micro or small furniture unit that has not yet begun its BIS application faces a real risk of being unable to legally sell covered products, because the licensing process involves factory inspection and laboratory testing that cannot be compressed into days. Starting immediately — and manufacturing under the correct documentation while the application is in process — is the only realistic path for late movers. The 2026 Amendment Orders: Practical Relief for Industry Two amendments have refined the QCO since notification, and both matter operationally. The Furniture (Quality Control) Amendment Order, 2026 — S.O. 774(E) dated 12 February 2026 — introduced targeted exemptions: furniture imported for research and development purposes (in limited quantity, not for commercial sale), provisions for clearing legacy stock manufactured before the enforcement date, and relief for components imported for use in export-oriented manufacturing, so that exporters are not forced to certify inputs destined for overseas markets. The Furniture (Quality Control) Second Amendment Order, 2026 — S.O. 1125(E) dated 2 March 2026 — further clarified the compliance framework for imports and transitional stock. Manufacturers and importers relying on any exemption should document their eligibility carefully, because the burden of proving an exemption applies rests with the party claiming it, and customs officers and BIS enforcement teams will ask for evidence. What the Furniture Standards Actually Test Understanding what the laboratory examines clarifies why certification takes preparation. The IS 17631–17636 series evaluates furniture against the hazards of real use, and each standard prescribes tests across four broad areas. Stability — the product must not tip over under defined loading conditions. Storage units are tested with loaded drawers and open doors; chairs are tested for forward, sideways, and rearward overturning; bunk beds for stability under a user’s weight at the guardrail. Strength — static

BIS Certification for Phosphoric Acid & Phosphite Chemicals in India: IS 798, IS 17439, IS 17412 and the Complete Compliance Process

Beyond the electronics and appliances most associated with BIS, India’s mandatory-certification framework has extended firmly into industrial chemicals — and phosphorus chemicals are a notable example. Ortho phosphoric acid, polyphosphoric acid, and trimethyl phosphite are important industrial inputs used across fertilisers, food and beverage processing, water treatment, metal finishing, flame retardants, and chemical synthesis. To ensure quality and consistency, these chemicals have been brought under mandatory BIS certification against their respective Indian Standards. For manufacturers and importers, BIS certification against the applicable standard is now the gateway to lawfully supplying these chemicals in India. This is a distinct area from the electronics categories, but the underlying principle is the same: a notified product must conform to its Indian Standard and be certified by BIS before it can be placed on the market. This guide covers the three phosphorus chemicals and their standards, the mandatory framework, the certification process, the documents required, realistic timelines, and the key points chemical manufacturers should understand. The Chemicals and Their Standards Three phosphorus chemicals are covered, each under its own Indian Standard, with defined implementation dates under their Quality Control Orders: Ortho Phosphoric Acid — IS 798:2020. A widely used mineral acid found in fertiliser production, food-grade applications (as a food additive and acidulant), metal treatment, and many industrial processes. Polyphosphoric Acid — IS 17439:2020. A condensed phosphoric acid used in chemical synthesis, catalysis, and specialised industrial applications. Trimethyl Phosphite (Technical Grade) — IS 17412:2020. An organophosphorus compound used as a chemical intermediate and reagent in synthesis, including in the manufacture of other chemicals. Each Indian Standard specifies the requirements for its chemical — including composition, purity, permissible impurities, and the test methods used to verify conformity. Manufacturers should obtain the current text of the applicable standard (IS 798, IS 17439, or IS 17412) and confirm the exact requirements and the current notification against the latest BIS position, since certification rests on demonstrated conformity to the correct standard and its current edition. The Mandatory Framework: QCOs and BIS Certification BIS certification operates under the Bureau of Indian Standards Act, 2016. When the Central Government issues a Quality Control Order for a product, it makes conformity to the corresponding Indian Standard — and BIS certification — mandatory. From the effective date of such an order, the product cannot lawfully be manufactured, stored, sold, or imported in India unless it conforms to the standard and carries the required BIS certification. Products manufactured solely for export are generally outside the order’s scope. For these phosphorus chemicals, the respective Quality Control Orders bring IS 798, IS 17439, and IS 17412 into mandatory effect, each with its own implementation date. Because the precise scheme mechanics and enforcement dates for chemical products are set by the applicable notification — and can differ from the electronics registration route — manufacturers should confirm the exact certification pathway, the effective dates, and any turnover-linked or category-specific provisions against the current BIS position for each chemical. What is constant is the underlying obligation: once notified, the chemical must conform to its Indian Standard and be BIS-certified, and non-compliance exposes a business to penalties under the BIS Act. Why These Chemicals Are Regulated The rationale for bringing these chemicals under mandatory certification is quality assurance and consumer and industrial safety. Phosphorus chemicals are used in sensitive applications — food-grade phosphoric acid enters the food chain, fertiliser-grade acid affects agricultural output, and technical-grade reagents feed into further chemical manufacturing. Substandard or contaminated product can compromise the safety and quality of everything downstream, from processed food and beverages to fertilisers and manufactured chemicals. A consistent, verified quality baseline protects buyers and the many industries that depend on these inputs, and it also curbs the entry of substandard imports. For manufacturers, certification is therefore both a legal requirement and a mark of the quality that serious industrial and food-sector customers increasingly demand. Why Grade and Purity Are Everything for These Chemicals For phosphorus chemicals, the entire value of the product lies in its grade and purity, which is exactly what the Indian Standards pin down and what mandatory certification protects. The same chemical name can span very different quality levels: phosphoric acid, for instance, is supplied as fertiliser grade, technical grade, and food grade, and the difference between them is a matter of controlled composition and strictly limited impurities. Food-grade phosphoric acid used as an acidulant in beverages must meet purity limits that keep harmful impurities such as heavy metals well below safe thresholds, because it enters the food chain directly; a fertiliser-grade product diverted into food use, or a contaminated batch, could cause real harm. Technical-grade reagents such as trimethyl phosphite feed into further chemical synthesis, where an off-specification input propagates defects into every downstream product. This is why the standards specify not just the headline assay but the permissible impurities and the test methods to verify them, and why certification hinges on demonstrating consistent conformity batch after batch rather than a one-off sample. For a manufacturer, the practical implication is that certification is fundamentally about proving reliable process control — that the plant can produce to grade consistently — which is the same capability that serious industrial and food-sector customers demand. Getting the quality system right is therefore both the route to certification and the foundation of a credible position in these quality-sensitive markets. The Certification Process BIS certification for a notified product follows the applicable scheme under the BIS conformity-assessment framework. For chemical products, the process centres on demonstrating that the product conforms to its Indian Standard, typically involving the following elements — though manufacturers should confirm the exact pathway for each chemical against the current notification. Confirm applicability and standard. Verify that the chemical falls within the notified scope and obtain the current text of the applicable standard (IS 798, IS 17439, or IS 17412). Establish testing and quality control. Ensure the manufacturing facility can produce product conforming to the standard, with the testing capability to verify composition, purity, and the other specified parameters

BIS ISI Certification for Domestic Gas Stoves for PNG in India: IS 17153:2019 and the Complete Licensing Process

As India expands its city-gas distribution networks, more and more households are cooking on Piped Natural Gas (PNG) rather than LPG cylinders — and the gas stoves designed for PNG are a distinct product with their own safety requirements. A PNG stove burns natural gas piped directly into the home at a different pressure and with different combustion characteristics than LPG, so it must be engineered and certified specifically for PNG service. Because a domestic gas stove is a combustion appliance used daily in the home, where a defect can lead to gas leaks, fire, or unsafe combustion, the Bureau of Indian Standards (BIS) requires domestic gas stoves for PNG to be certified against a dedicated Indian Standard, IS 17153:2019, and to carry the ISI Mark under a BIS licence. For manufacturers and importers, BIS ISI certification against this standard is the mandatory gateway to the Indian market. PNG domestic gas stoves are covered under a Quality Control Order that makes conformity to IS 17153:2019 and the ISI Mark mandatory. This guide explains what the standard covers, why PNG stoves are certified separately from LPG stoves, how the BIS certification process works for Indian and foreign manufacturers, the documents required, realistic timelines and costs, and the mistakes that most often delay a licence. The Legal Framework: QCOs and the ISI Mark BIS certification operates under the Bureau of Indian Standards Act, 2016. When the Central Government issues a Quality Control Order for a product, conformity to the corresponding Indian Standard — and display of the ISI Mark under a BIS licence — becomes mandatory. From the effective date, a covered product cannot lawfully be manufactured, stocked, sold, or imported in India unless it bears the ISI Mark with a valid CM/L licence number. Products manufactured solely for export are generally outside the order’s scope. For domestic PNG gas stoves, IS 17153:2019 is the technical specification the order references. Manufacturers should confirm the exact notification, effective dates, and any turnover-linked timelines against the current BIS position, since enforcement is phased and periodically clarified. The underlying obligation is constant: once notified, the ISI Mark under a BIS licence is the passport to the Indian market, and non-compliance invites penalties under the BIS Act. For a gas-combustion appliance used in the home, the certification is also a genuine assurance to households, city-gas distributors, and safety authorities that the stove is safe for PNG service. What IS 17153:2019 Covers and Why PNG Is Different IS 17153:2019 is the Indian Standard specification for domestic gas stoves for use with Piped Natural Gas (PNG). It sets out the requirements for PNG cooking stoves — covering construction and materials, the burners and their combustion performance on natural gas, gas soundness (freedom from leaks), the safety of the gas-carrying components and connections, thermal and mechanical safety, marking, and the tests that verify all of these. The key reason PNG stoves are certified separately from LPG stoves is that natural gas and LPG are different fuels with different compositions, calorific values, and supply pressures. A burner and gas train designed for LPG will not burn PNG correctly — the flame characteristics, gas-flow requirements, and injector sizing differ — so a stove must be specifically designed and certified for the fuel it will actually use. IS 17153:2019 addresses PNG service specifically, ensuring the stove burns natural gas cleanly and safely, remains gas-tight, and is safe to operate. A stove that passes the standard gives assurance that it is engineered for PNG and safe in the home. Manufacturers should design and test explicitly to the current clauses of IS 17153:2019. This fuel-specificity has a practical consequence for manufacturers who sell both LPG and PNG stoves, or dual-fuel models: each fuel configuration must be treated on its own terms for certification, and a PNG model cannot ride on an LPG model’s approval. As PNG adoption grows city by city, a manufacturer expanding from an LPG range into PNG should plan a distinct certification for its PNG stoves against IS 17153:2019 rather than assuming its existing LPG credentials transfer. Getting this right from the design stage — correct injectors, burner tuning, and gas train for natural gas — is both what makes the stove safe on PNG and the foundation of a clean ISI licence. Who Needs BIS Certification for PNG Gas Stoves The requirement reaches across the supply chain: Indian manufacturers of domestic PNG gas stoves, who must hold a BIS licence to apply the ISI Mark before selling in India. Importers and foreign manufacturers, whose stoves must be certified — foreign factories through the BIS Foreign Manufacturers Certification Scheme (FMCS) — before import. City-gas distributors and retailers, who increasingly require ISI-marked PNG stoves as the PNG customer base grows, making certification a supply requirement. As city-gas networks expand and PNG connections multiply across Indian cities, demand for compliant PNG stoves is rising, and ISI certification is both a legal requirement and a commercial gate for this growing market. Step-by-Step: The BIS ISI Certification Process BIS grants ISI licences under Scheme-I of the BIS (Conformity Assessment) Regulations. Our team manages each stage end to end, but every applicant should understand the sequence. Confirm applicability and standard. Verify the stove falls within the notified scope for IS 17153:2019 (PNG stoves specifically) and obtain the current standard text. Prepare the factory and in-house testing. BIS certification is factory-based; the premises must have the machinery and in-house testing facilities — including gas-combustion and soundness testing capability — to verify conformity on an ongoing basis. File the application on the BIS portal. Submit through the BIS Manak online system with the required documentation. Foreign manufacturers apply under FMCS and nominate an Authorised Indian Representative (AIR). Factory inspection. A BIS officer inspects the unit, verifies the process and testing capability, and witnesses testing. Sample testing. Samples are drawn and tested — in the factory and/or at a BIS-recognised laboratory — against IS 17153:2019, including combustion, gas-soundness, and safety tests. Grant of licence. On satisfactory inspection and

BIS ISI Certification for Wheeled Fire Extinguishers in India: IS 16018:2012 and the Complete Licensing Process

Where a portable fire extinguisher tackles a small, incipient fire, a wheeled fire extinguisher is built for bigger threats — the larger, higher-capacity, trolley-mounted units used in factories, warehouses, fuel depots, airports, large commercial buildings, and industrial sites where a serious fire demands far more extinguishing agent than a handheld unit can carry. Because these are high-capacity, pressurised life-safety devices protecting high-risk environments, the Bureau of Indian Standards (BIS) requires wheeled fire extinguishers to be certified against a dedicated Indian Standard, IS 16018:2012, and to carry the ISI Mark under a BIS licence. For manufacturers and importers, BIS ISI certification against this standard is the mandatory gateway to the Indian market. Wheeled extinguishers are covered under a Quality Control Order that makes conformity to IS 16018:2012 and the ISI Mark mandatory. This guide explains what the standard covers, how the BIS certification process works for Indian and foreign manufacturers, the documents required, realistic timelines and costs, the link to PESO for pressure vessels, and the mistakes that most often delay a licence. The Legal Framework: QCOs and the ISI Mark BIS certification operates under the Bureau of Indian Standards Act, 2016. When the Central Government issues a Quality Control Order for a product, conformity to the corresponding Indian Standard — and display of the ISI Mark under a BIS licence — becomes mandatory. From the effective date, a covered product cannot lawfully be manufactured, stocked, sold, or imported in India unless it bears the ISI Mark with a valid CM/L licence number. Products manufactured solely for export are generally outside the order’s scope. For wheeled fire extinguishers, IS 16018:2012 is the technical specification the order references. Manufacturers should confirm the exact notification, effective dates, and any turnover-linked timelines against the current BIS position, since enforcement is phased and periodically clarified. The underlying obligation is constant: once notified, the ISI Mark under a BIS licence is the passport to the Indian market, and non-compliance invites penalties under the BIS Act. For a life-safety product protecting high-risk industrial sites, the certification is also a genuine assurance to safety officers, insurers, and inspecting authorities that the equipment will perform under demand. What IS 16018:2012 Covers IS 16018:2012 is the Indian Standard specification for wheeled fire extinguishers. It sets out the requirements for the larger, trolley-mounted extinguishers of the various agent types (dry powder, foam, carbon dioxide, and others), covering their construction and the pressure integrity of the body, the wheeled trolley and mobility arrangement, the discharge performance and fire-rating appropriate to their higher capacity, the reliability of the operating and discharge mechanism, marking, and the tests that verify all of these. Because a wheeled extinguisher combines a high-capacity pressure vessel with a mobile trolley and a discharge system capable of tackling a large fire, the standard addresses the mechanical integrity of the pressure-bearing body, the robustness and mobility of the trolley, and the functional fire-fighting performance. An extinguisher that passes IS 16018:2012 gives assurance that it will hold pressure safely, be movable to the fire, and discharge its agent effectively at the rated capacity. Manufacturers should design and test explicitly to the current clauses of IS 16018:2012. Who Needs BIS Certification for Wheeled Extinguishers The requirement reaches across the supply chain: Indian manufacturers of wheeled fire extinguishers, who must hold a BIS licence to apply the ISI Mark before selling in India. Importers and foreign manufacturers, whose products must be certified — foreign factories through the BIS Foreign Manufacturers Certification Scheme (FMCS) — before import. Industrial buyers, safety officers, and fire consultants, who specify ISI-marked wheeled extinguishers for high-risk sites, making certification a bidding and deployment requirement. Because wheeled extinguishers protect factories, fuel installations, and other high-hazard environments where fire-safety compliance is closely scrutinised, ISI certification is both a legal requirement and a commercial necessity. The PESO Dimension: Pressure Vessels As with portable extinguishers — and even more so given their higher capacity — wheeled fire extinguishers are pressure vessels, which brings the Petroleum and Explosives Safety Organisation (PESO) into the picture alongside BIS. The high-capacity body holds its agent under pressure, and CO2 units store large volumes of high-pressure gas, so the pressure-bearing aspects engage the regulatory framework for gas cylinders and pressure vessels administered by PESO under the applicable rules. This is distinct from the BIS ISI certification — BIS certifies the product against IS 16018:2012, while PESO addresses the pressure-vessel/gas-cylinder safety aspects — but both may be relevant depending on the extinguisher type and construction. For a manufacturer, the higher pressures and larger vessels of wheeled units make the PESO dimension particularly important, and the BIS and PESO requirements should be planned together. See our PESO licensing and approvals service for the pressure-vessel dimension; the rest of this guide focuses on BIS ISI certification. Step-by-Step: The BIS ISI Certification Process BIS grants ISI licences under Scheme-I of the BIS (Conformity Assessment) Regulations.

BIS ISI Certification for Portable Fire Extinguishers in India: IS 15683:2018 and the Complete Licensing Process

A fire extinguisher is a life-safety product whose failure is measured not in inconvenience but in lives and property. When a fire breaks out in a home, office, factory, vehicle, or public building, a portable fire extinguisher is often the first — and sometimes the only — line of defence, and it must work reliably the moment it is needed. Because so much depends on these devices performing exactly as designed, the Bureau of Indian Standards (BIS) requires portable fire extinguishers to be certified against a dedicated Indian Standard, IS 15683:2018, and to carry the ISI Mark under a BIS licence. For manufacturers and importers, BIS ISI certification against this standard is the mandatory gateway to the Indian market. Portable fire extinguishers are covered under a Quality Control Order that makes conformity to IS 15683:2018 and the ISI Mark mandatory. This guide explains what the standard covers, how the BIS certification process works for both Indian and foreign manufacturers, the documents required, realistic timelines and costs, the important link to PESO for pressure vessels, and the mistakes that most often delay a licence. The Legal Framework: QCOs and the ISI Mark BIS certification operates under the Bureau of Indian Standards Act, 2016. When the Central Government issues a Quality Control Order for a product, conformity to the corresponding Indian Standard — and display of the ISI Mark under a BIS licence — becomes mandatory. From the effective date, a covered product cannot lawfully be manufactured, stocked, sold, or imported in India unless it bears the ISI Mark with a valid licence (CM/L) number. Products manufactured solely for export are generally outside the order’s scope. For portable fire extinguishers, IS 15683:2018 is the technical specification that the Quality Control Order references. Manufacturers should confirm the exact notification, its effective dates, and any turnover-linked implementation timelines against the current BIS position, since enforcement is phased and periodically clarified. What does not change is the underlying obligation: once notified, the ISI Mark under a BIS licence is the passport to the Indian market, and non-compliance exposes a business to penalties under the BIS Act, including fines and seizure. Given that fire extinguishers are life-safety products, the certification is also a genuine assurance to buyers, fire consultants, and inspecting authorities that the product will perform. What IS 15683:2018 Covers IS 15683:2018 is the Indian Standard specification for portable fire extinguishers — performance and construction. It sets out the requirements for portable extinguishers of the various types (water, foam, dry powder, carbon dioxide, and others) used to tackle different classes of fire, covering their construction, the materials and pressure integrity of the body, the discharge performance and fire-rating that determine how effectively the extinguisher tackles a fire, the reliability of the operating mechanism, marking, and the tests that verify all of these. Because a portable extinguisher is a pressurised device that must discharge its agent effectively on demand, the standard addresses both the mechanical integrity of the pressure-bearing body and the functional fire-fighting performance. An extinguisher that passes IS 15683:2018 gives assurance that it will hold pressure safely, discharge its agent as intended, and deliver the fire-rating claimed. Manufacturers should design and test explicitly to the current clauses of IS 15683:2018, since the certification stands or falls on demonstrated conformity to the standard. Who Needs BIS Certification for Fire Extinguishers The requirement reaches across the supply chain for these life-safety products: Indian manufacturers of portable fire extinguishers, who must hold a BIS licence to apply the ISI Mark before selling in India. Importers and foreign manufacturers, whose products must be certified — foreign factories through the BIS Foreign Manufacturers Certification Scheme (FMCS) — before the extinguishers can be imported. Refilling and servicing businesses and buyers, who increasingly require ISI-marked extinguishers from licensed sources, since fire-safety compliance in buildings depends on approved equipment. Because fire extinguishers are specified in building fire-safety norms and bought by fire consultants, facility managers, and institutions, ISI certification is both a legal requirement and a commercial necessity — an uncertified extinguisher is effectively unsaleable to serious buyers. The PESO Dimension: Pressure Vessels An important point specific to fire extinguishers is that they are pressure vessels, and this brings the Petroleum and Explosives Safety Organisation (PESO) into the picture alongside BIS. The body of an extinguisher holds its agent under pressure (and CO2 extinguishers store high-pressure gas), so the pressure-bearing aspects engage the regulatory framework for gas cylinders and pressure vessels administered by PESO under the applicable rules. This is distinct from the BIS ISI certification — BIS certifies the product against IS 15683:2018, while PESO addresses the pressure-vessel/gas-cylinder safety aspects — but both may be relevant for a fire extinguisher depending on its type and construction. For a manufacturer, the practical lesson is that a fire extinguisher’s compliance file can span two authorities, and the BIS and PESO requirements should be planned together. See our PESO licensing and approvals service for the pressure-vessel dimension; the rest of this guide focuses on the BIS ISI certification.

BIS CRS Registration for Thin-Film Solar PV Modules in India: IS 14286, IS/IEC 61730 and the Complete Process

Thin-film solar modules are a distinct branch of photovoltaic technology, using thin layers of semiconductor material — amorphous silicon (a-Si), copper indium gallium selenide (CIGS), or cadmium telluride (CdTe) — deposited on a substrate, rather than the silicon wafers of conventional crystalline modules. They offer particular advantages in certain applications, from utility-scale plants to building-integrated and flexible installations. As India’s solar deployment scales up, the quality and safety of thin-film modules matters as much as that of crystalline ones, and thin-film terrestrial PV modules are notified under the BIS Compulsory Registration Scheme (CRS). A covered module must be registered before it can be sold or used in India, making BIS CRS registration the mandatory quality-and-safety gateway for thin-film modules. Thin-film modules have their own design-qualification standards, distinct from the crystalline-silicon route, reflecting their different construction and technology. This guide explains the applicable standards, the CRS process, the documents required, realistic timelines, and how the registration fits within the wider solar-compliance picture. Why Thin-Film PV Modules Fall Under CRS The Compulsory Registration Scheme operates under the Electronics and Information Technology Goods (Requirement of Compulsory Registration) Order, administered by BIS under the BIS Act, 2016. Thin-film terrestrial photovoltaic modules (a-Si, CIGS, and CdTe) are notified under CRS, meaning a covered module must be tested against the applicable Indian Standards, registered with BIS, and marked with its registration number before it can be sold or used in India. The rationale is both safety and quality. A PV module is deployed outdoors for a design life measured in decades, exposed to sun, heat, rain, wind, and mechanical stress, and it generates electricity feeding into installations and the grid. A module that fails prematurely, delaminates, or poses an electrical-safety risk undermines the economics and safety of the whole installation. CRS ensures every module meets a common design-qualification and safety baseline verified through testing. Selling or using an unregistered notified module is an offence under the BIS Act, and registration is also a hard commercial gate for developers, EPC contractors, and government-supported schemes. The Applicable Standards: IS 14286 (Part 1) and IS/IEC 61730 Thin-film module registration engages design-qualification and safety standards specific to thin-film technology. The design-qualification and type-approval standards are the relevant sections of IS 14286 (Part 1) for thin-film technologies — Sections 2, 3, and 4 addressing the different thin-film types (a-Si, CIGS, and CdTe), aligned with the corresponding parts of IEC 61215-1 — together with the module-safety standards IS/IEC 61730-1 and IS/IEC 61730-2. In other words, thin-film modules rest on the same two pillars as crystalline ones — a design-qualification standard confirming durability and performance, and a safety standard confirming electrical and mechanical safety — but the design-qualification sections are technology-specific to thin film. Manufacturers should confirm the exact applicable IS 14286 section for their specific thin-film technology, along with the IS/IEC 61730 safety parts and their current editions, against the latest BIS notification before testing, since the standard set is detailed and technology-specific. Mapping the module to the correct section for its technology is the essential first step. What the Testing Examines Understanding what the laboratory checks clarifies why registration matters for a thin-film module. The design-qualification testing under the applicable IS 14286 section subjects the module to a demanding sequence intended to simulate decades of outdoor exposure in accelerated form — thermal cycling between temperature extremes, humidity-freeze and damp-heat exposure, mechanical load testing for wind and snow, and other stresses — with test details appropriate to thin-film construction, to confirm the module will endure real-world conditions without unacceptable degradation. Thin-film modules have particular degradation behaviours (such as initial light-induced effects in some technologies) that the qualification process accounts for. The safety testing under IS/IEC 61730 addresses electrical safety — insulation, protection against shock, and safe construction — and the module’s ability to withstand fire and mechanical hazards. Together, these establish that the thin-film module is both durable and safe. Because a PV module is a long-life outdoor product carrying electrical energy, and substandard modules can fail dangerously or prematurely over a long design life, this rigorous, technology-appropriate testing is central — which is why India requires it rather than accepting unverified claims. Thin-Film vs Crystalline: Why the Distinction Matters The key insight for a thin-film module manufacturer is that thin-film and crystalline modules, while both PV modules, are certified under different design-qualification sections reflecting their genuinely different technologies — and getting the classification right is the foundation of the whole process. Crystalline-silicon modules use the IS 14286 (Part 1/Section 1) route, while thin-film modules use Sections 2, 3, or 4 according to whether the technology is amorphous silicon, CIGS, or cadmium telluride. This is not a mere formality: thin-film modules are built differently, degrade differently, and are tested with protocols suited to their construction, so a thin-film module cannot be certified on a crystalline module’s route, and a manufacturer must identify the correct section for its specific technology before any testing begins. Beyond CRS, thin-film modules sit within the same broader solar-policy framework as crystalline ones — the government’s Approved List of Models and Manufacturers (ALMM) governs eligibility for many projects, and this is distinct from but often practically essential alongside the BIS registration. For a manufacturer, the practical lesson is twofold: map the module to the correct thin-film design-qualification section and safety standards for CRS, and plan ALMM enrolment in parallel, treating the two as coordinated parts of a broader solar-compliance programme. Serious market access for thin-film modules, as for crystalline, typically requires attention to both.

BIS CRS Registration for Franking & Mail-Processing Machines in India: IS 13252 and the Complete Compliance Process

Mail-processing machines — including postage and franking machines — remain essential equipment for organisations that handle mail in volume: corporate mailrooms, banks, government departments, courier and logistics operations, and print-and-mail service bureaus. A franking machine prints postage impressions directly onto mail, accounting for postage automatically; broader mail-processing machines fold, insert, seal, sort, and meter mail at speed. These are mains-connected electronic systems combining processing electronics, a printing mechanism, and mechanical paper-and-envelope handling. Because they are notified electronic products, mail-processing, postage, and franking machines fall under the BIS Compulsory Registration Scheme (CRS). A covered machine must be registered before it can be imported or sold in India, making BIS CRS registration the mandatory safety gateway to the market. Franking machines in particular sit within a specialised postal-approval environment, since they meter postage on behalf of the postal authority. This guide explains the applicable standard, the CRS self-declaration process, the documents required, realistic timelines, and how the safety registration fits within the wider compliance picture. Why Mail-Processing Machines Fall Under CRS The Compulsory Registration Scheme operates under the Electronics and Information Technology Goods (Requirement of Compulsory Registration) Order, administered by BIS under the BIS Act, 2016. Mail-processing machines, postage machines, and franking machines are notified under CRS, meaning a covered machine must be tested against the applicable Indian Standard, registered with BIS, and marked with its registration number before it can be manufactured, imported, sold, distributed, or stored for sale in India. The safety rationale is direct. A mail-processing machine is mains-connected, draws meaningful power, and combines electronics with a printing mechanism and fast-moving mechanical paper-and-envelope handling, operated by mailroom staff throughout the working day. Substandard power electronics, poor thermal handling, or inadequate mechanical guarding can create shock, injury, or fire hazards. CRS ensures every machine meets a common safety baseline verified by India-specific testing. Selling an unregistered notified machine is an offence under the BIS Act, and registration is also a commercial gate: corporate and government buyers verify it, and customs checks it at import. The Applicable Standard: IS 13252 (Part 1):2010 Mail-processing, postage, and franking machines are registered under IS 13252 (Part 1):2010, the Indian Standard for the safety of information technology equipment (adopted from IEC 60950-1). This addresses protection against electric shock, energy and thermal hazards, fire containment, and mechanical construction as they apply to IT equipment. Manufacturers should confirm the exact applicable standard and its current edition against the latest BIS notification before testing, since certification rests on demonstrated conformity to the correct standard. The machine must be tested at a BIS-recognised laboratory and shown to conform before it can be registered. What the CRS Safety Test Examines Understanding what the laboratory checks clarifies why registration matters. The safety standard evaluates the machine against a defined set of hazards. Electric-shock protection is verified for the mains-connected power system. Thermal behaviour is assessed under sustained operation, since mailroom machines can run large batches continuously. Fire-containment and fault-condition provisions confirm that a failure is contained. Mechanical requirements are especially relevant here — the machine has a printing mechanism and fast-moving parts that fold, insert, and feed paper and envelopes, and these must be guarded so an operator’s hands are protected, with access covers and interlocks appropriate to the moving mechanisms. Because a mail-processing machine combines mains power, printing, and fast mechanical handling in an operator-facing device, electrical, thermal, and mechanical safety are all genuinely relevant, which is why India requires local testing rather than accepting overseas certificates alone. Safety Registration and the Postal-Approval Layer The defining context for franking and postage machines, and the key insight for a manufacturer, is that these machines meter postage on behalf of the postal authority, which places them within a specialised postal-approval regime that runs alongside — but distinct from — their BIS electrical-safety registration. A franking machine prints official postage impressions and accounts for the postage value, which means it must be approved and licensed by the postal authority (India Post) to ensure it meters postage accurately and securely and cannot be tampered with to defraud the postal system. This postal approval and licensing is entirely separate from the CRS safety registration — CRS concerns electrical and mechanical safety, while the postal regime concerns metering accuracy, security, and authorisation to frank mail — but for a franking machine, both are essential: the CRS registration to sell it as safe equipment, and the postal approval to lawfully use it to meter postage. For a manufacturer, the practical lesson is that a franking machine’s compliance file spans two very different authorities, and the BIS safety registration, while mandatory, is only part of what makes the machine deployable. Broader mail-processing machines that do not themselves meter postage face the CRS safety requirement without the postal-metering layer. Mapping each machine to its full set of requirements — CRS for all, plus postal approval for franking/postage functions — and treating them as one coordinated programme is what makes a franking machine genuinely usable for its purpose. It is also worth appreciating the breadth of the mail-processing category, which shapes how a manufacturer should scope compliance. At one end are compact desktop franking machines used by small offices; at the other are large, high-throughput production systems in commercial mailrooms and print-mail bureaus that fold, insert, seal, weigh, meter, and sort thousands of mailpieces an hour. The larger, faster machines carry far more mechanical complexity — powerful motors, high-speed feed paths, and multiple moving stations — which brings the mechanical-safety aspects of the assessment more sharply into focus. A manufacturer with a range across these formats should scope each machine’s testing to its actual configuration and speed rather than assuming a small franker’s approach carries across to a production inserter, while using series grouping where machines genuinely share a platform. This keeps the registrations both accurate to the real equipment and efficient to obtain across a diverse mailroom portfolio.

BIS CRS Registration for LED Hand Lamps in India: IS 10322 (Part 5/Section 6) and the Complete Process

LED hand lamps — the portable, handheld inspection lamps and work lights used by mechanics, electricians, technicians, engineers, and maintenance crews — are rugged tools that bring light into engine bays, machinery, workshops, basements, and confined spaces across India’s industrial and service sectors. A hand lamp is a portable luminaire, held or hung by the user, often connected to the mains by a trailing cable and built to withstand knocks, drops, oil, and dust. Because these are notified lighting products, LED hand lamps fall under the BIS Compulsory Registration Scheme (CRS). A covered hand lamp must be registered before it can be sold in India, making BIS CRS registration the mandatory safety gateway to the market. Hand lamps are a distinct luminaire category with their own safety standard, reflecting the particular demands of a portable, handheld, hard-used light. This guide explains the applicable standard, the CRS self-declaration process, the documents required, realistic timelines, and how the safety registration fits within the wider compliance picture. Why LED Hand Lamps Fall Under CRS The Compulsory Registration Scheme operates under the Electronics and Information Technology Goods (Requirement of Compulsory Registration) Order, administered by BIS under the BIS Act, 2016. LED hand lamps are notified under CRS, meaning a covered hand lamp must be tested against the applicable Indian Standard, registered with BIS, and marked with its registration number before it can be manufactured, imported, sold, distributed, or stored for sale in India. The safety rationale is direct and heightened by how hand lamps are used. A hand lamp is held directly in the hand, often in demanding environments — engine bays with oil and fuel, damp basements, dusty workshops, and confined spaces — and it is frequently connected to the mains by a trailing cable that is pulled, coiled, and stressed. Substandard construction, poor insulation, a weak cable, or inadequate protection against ingress can create serious electric-shock or fire hazards precisely where a user is in direct contact with the lamp. CRS ensures every hand lamp meets a common safety baseline verified by India-specific testing. Selling an unregistered notified hand lamp is an offence under the BIS Act, and registration is also a commercial gate: industrial buyers, tool distributors, and marketplaces verify it, and customs checks it at import. The Applicable Standard: IS 10322 (Part 5/Section 6) LED hand lamps are registered under IS 10322 (Part 5/Section 6):2013, the Indian Standard for luminaires — particular requirements for hand lamps, within the IS 10322 series (aligned with the international IEC 60598 luminaire-safety family). Part 5 addresses particular luminaire categories, and Section 6 addresses hand lamps specifically, reflecting the additional considerations of a portable, handheld luminaire. The standard covers protection against electric shock with particular attention to a handheld device, the integrity and strain relief of the supply cable, the ingress protection needed for use in harsh environments, mechanical robustness against drops and impacts, and thermal behaviour. Manufacturers should confirm the exact applicable standard, section, and current edition against the latest BIS notification before testing, since certification rests on demonstrated conformity to the correct standard. The hand lamp must be tested at a BIS-recognised laboratory and shown to conform before it can be registered. What the CRS Safety Test Examines Understanding what the laboratory checks clarifies why registration matters for a hand lamp. The hand-lamp safety standard evaluates the device against a defined set of hazards. Electric-shock protection is verified with particular rigour because the user holds the lamp directly — the insulation and the barrier between live parts and the user’s hand must be robust. The supply cable and its strain relief are examined, since the cable is repeatedly pulled and stressed and its connection to the lamp must not work loose or expose conductors. Ingress protection is assessed for the harsh environments hand lamps face, so oil, water, and dust cannot reach live parts. Mechanical robustness is tested against the drops and impacts a handheld work light inevitably suffers. Thermal behaviour and fault-condition behaviour are checked. Because a hand lamp is held directly by the user in demanding conditions with a stressed trailing cable, shock protection, cable integrity, ingress protection, and impact resistance are all especially central, which is why India requires local testing rather than accepting overseas certificates alone. Built for Abuse: Why Hand Lamps Are Their Own Category The reason hand lamps have a dedicated standard, and the key insight for a manufacturer, is that a handheld work light lives a fundamentally harder and more hazardous life than a fixed luminaire, and its safety must be engineered for that reality. Unlike a ceiling fitting installed once and left alone, a hand lamp is picked up, dropped, dragged by its cable, splashed with oil and water, wedged into tight spaces, and gripped by hands that may be wet or greasy — all while being held in direct contact with the user and connected to the mains. Every one of these conditions is a potential safety hazard, and the standard is written precisely to ensure the lamp withstands them: robust insulation and shock protection because the user holds it, strong cable strain relief because the cable takes abuse, ingress protection because the environment is dirty and wet, and impact resistance because the lamp gets knocked about. This is why a hand lamp cannot be treated as just another luminaire and certified to the general requirements — its handheld, hard-used nature demands the particular protections of Section 6. For a manufacturer, the lesson is that building genuine ruggedness and safety into a hand lamp — quality cable and strain relief, sound insulation, a sealed and impact-resistant housing — is both what makes the product fit for the tough jobs it is bought for and the foundation of a clean CRS registration. The two are inseparable: a hand lamp that is genuinely safe for a mechanic to use is the one that passes the standard.

BIS CRS Registration for Passport Readers in India: IS 13252 and the Complete Compliance Process

Passport readers are specialised scanning devices that read the data pages and chips of passports and travel documents — used at immigration counters, airports, visa centres, hotels, banks, and any point where identity must be verified against a travel document. A passport reader is a compact electronic device, usually USB-connected, that optically scans the machine-readable zone and, in e-passport readers, communicates with the document’s embedded chip. Because these are notified electronic products, passport readers fall under the BIS Compulsory Registration Scheme (CRS). A covered reader must be registered before it can be imported or sold in India, making BIS CRS registration the mandatory safety gateway to the market. Passport readers are deployed heavily in government, border-control, travel, and hospitality settings, often through structured procurement where compliance is verified. This guide explains the applicable standard, the CRS self-declaration process, the documents required, realistic timelines, and how the safety registration fits within the wider compliance picture. Why Passport Readers Fall Under CRS The Compulsory Registration Scheme operates under the Electronics and Information Technology Goods (Requirement of Compulsory Registration) Order, administered by BIS under the BIS Act, 2016. Passport readers are notified under CRS, meaning a covered device must be tested against the applicable Indian Standard, registered with BIS, and marked with its registration number before it can be manufactured, imported, sold, distributed, or stored for sale in India. The safety rationale, while proportionate to the low power involved, is real. A passport reader is powered — typically over USB — and contains optical, imaging, and (for e-passport readers) RF chip-reading electronics, used continuously at counters and desks. Substandard construction or poor electrical design can create a hazard. CRS ensures every reader meets a common safety baseline verified by India-specific testing. Selling an unregistered notified reader is an offence under the BIS Act, and registration is also a commercial gate: government agencies, system integrators, and institutional buyers verify it, and customs checks it at import. The Applicable Standard: IS 13252 (Part 1):2010 Passport readers are registered under IS 13252 (Part 1):2010, the Indian Standard for the safety of information technology equipment (adopted from IEC 60950-1). This addresses protection against electric shock, energy and thermal hazards, fire containment, and mechanical construction as they apply to IT equipment — appropriate for these USB-connected peripherals. Manufacturers should confirm the exact applicable standard and its current edition against the latest BIS notification before testing, since certification rests on demonstrated conformity to the correct standard. The reader must be tested at a BIS-recognised laboratory and shown to conform before it can be registered. What the CRS Safety Test Examines Understanding what the laboratory checks clarifies why registration matters even for a small peripheral. The safety standard evaluates the reader against a defined set of hazards. Electric-shock protection is verified for the USB-powered circuitry. Thermal behaviour is assessed so the device does not overheat during continuous use at busy immigration and reception desks. Fire-containment and fault-condition provisions confirm that an internal failure is contained. Construction requirements examine the enclosure, the document-scanning surface, and connectors. For readers with an illuminating light source for optical scanning, optical-safety aspects are considered so emitted light is safely contained. Because a passport reader is a low-power but continuously used device, the electrical, thermal, and construction fundamentals are the areas assessed, which is why India requires local testing rather than accepting overseas certificates alone. It is also worth noting the range within the category: simple optical readers that scan only the printed machine-readable zone sit at one end, while full-page e-passport readers that also energise and read the document’s contactless chip, and combine optical, infrared, and ultraviolet imaging for authentication, sit at the other. The more capable readers carry more electronics and, in the case of chip-reading, an RF interface, so a manufacturer should scope each model’s compliance to its actual capabilities rather than assuming one approach covers the range. Safety Registration Within a Security and Interoperability World The essential context for passport readers, and the key insight for a manufacturer, is that the BIS CRS registration addresses the device’s electrical safety, while the reader operates within a demanding ecosystem of security, data-handling, and interoperability requirements set by the applications it serves. Passport readers are used in border control, immigration, and identity verification — highly sensitive domains where the device must read international travel documents to global standards (such as the ICAO specifications for machine-readable travel documents and e-passport chips), handle personal and biometric data securely, and interoperate with immigration and identity systems. These application, security, and interoperability requirements are entirely distinct from the CRS safety registration — CRS concerns electrical safety, while the others concern document-reading standards, data security, and system integration — but for a passport reader intended for government or border-control use, they are just as essential to actually deploy the device. For a manufacturer, the practical lesson is that CRS is the necessary safety foundation common to all passport readers, while the security and interoperability certifications determine whether a given reader can be used in the specific immigration, travel, or identity systems it targets. Mapping the reader to its full set of requirements — CRS for all, plus the application-specific standards for its intended use — and treating these as one coordinated programme is what makes a passport reader genuinely deployable in the security-critical settings it is built for.

BIS CRS Registration for Telephone Answering Machines in India: IS 13252 and the Complete Compliance Process

Telephone answering machines — the devices that record incoming voice messages when a call goes unanswered — remain in use across offices, small businesses, clinics, and homes in India, whether as standalone units or as functions built into telephone systems and PBX equipment. A telephone answering machine is a mains-connected electronic device that connects to the telephone line, records and plays back messages, and manages call handling. Because these are notified electronic products, telephone answering machines fall under the BIS Compulsory Registration Scheme (CRS). A covered device must be registered before it can be imported or sold in India, making BIS CRS registration the mandatory safety gateway to the market. Answering machines sit at the intersection of electronics and telecom equipment, and while CRS addresses their electrical safety, understanding the wider picture helps a manufacturer get to market cleanly. This guide explains the applicable standard, the CRS self-declaration process, the documents required, realistic timelines, and how the safety registration fits within the broader compliance environment. Why Telephone Answering Machines Fall Under CRS The Compulsory Registration Scheme operates under the Electronics and Information Technology Goods (Requirement of Compulsory Registration) Order, administered by BIS under the BIS Act, 2016. Telephone answering machines are notified under CRS, meaning a covered device must be tested against the applicable Indian Standard, registered with BIS, and marked with its registration number before it can be manufactured, imported, sold, distributed, or stored for sale in India. The safety rationale is direct. A telephone answering machine is mains-connected, contains audio and processing electronics, and connects to the telephone network, used continuously in offices and homes. Substandard construction or poor electrical design can create shock, overheating, or fire hazards. CRS ensures every device meets a common safety baseline verified by India-specific testing. Selling an unregistered notified device is an offence under the BIS Act, and registration is also a commercial gate: dealers and marketplaces verify it, and customs checks it at import. The Applicable Standard: IS 13252 (Part 1):2010 Telephone answering machines are registered under IS 13252 (Part 1):2010, the Indian Standard for the safety of information technology equipment (adopted from IEC 60950-1). This addresses protection against electric shock, energy and thermal hazards, fire containment, and mechanical construction as they apply to IT equipment. Manufacturers should confirm the exact applicable standard and its current edition against the latest BIS notification before testing, since certification rests on demonstrated conformity to the correct standard. The device must be tested at a BIS-recognised laboratory and shown to conform before it can be registered. What the CRS Safety Test Examines Understanding what the laboratory checks clarifies why registration matters. The safety standard evaluates the device against a defined set of hazards. Electric-shock protection is verified for the mains-connected power system, and the interface to the telephone line is considered from a safety standpoint, since the device connects to external network wiring. Thermal behaviour is assessed so the electronics stay within safe temperatures during continuous operation. Fire-containment and fault-condition provisions confirm that an internal failure is contained. Construction requirements examine the enclosure, connectors, and any moving parts. Because a telephone answering machine is a mains-connected, always-available device linked to the telephone network, the electrical, thermal, and network-interface safety fundamentals are the relevant areas, which is why India requires local testing rather than accepting overseas certificates alone. Electronics Safety and the Telecom Dimension The instructive point about telephone answering machines is that they straddle two worlds — consumer electronics and telecom equipment — and a manufacturer should understand how this shapes the compliance picture. The BIS CRS registration under IS 13252 addresses the device’s electrical safety as IT equipment, which is the mandatory basis for placing it on the market. But because the device connects to the telephone network, telecom-equipment considerations can also be relevant: equipment that interfaces with the public telecom network may engage the Department of Telecommunications’ certification requirements under the Mandatory Testing and Certification of Telecom Equipment regime, depending on the exact product and how it connects. These telecom requirements are distinct from the CRS safety registration — CRS concerns electrical safety, while telecom certification concerns network interface and performance — but both may be relevant for a network-connected device. For a manufacturer, the practical lesson is to map the product’s actual connectivity and functions to its full set of requirements, with CRS safety as the foundation and any telecom-certification layer added according to how the device interfaces with the network. This is especially relevant today because standalone answering machines have largely given way to answering functions integrated into telephones, PBX systems, and VoIP equipment, which can bring the telecom dimension more clearly into scope. Getting this classification right at the outset keeps the compliance programme correctly and efficiently scoped. There is also a broader lesson here about how India’s mandatory-certification framework treats legacy and evolving product categories. Telephone answering machines were notified under CRS in an earlier wave of the scheme, and even as the standalone product has faded in favour of integrated and internet-based voicemail, the notification remains in force, so a manufacturer or importer still supplying such devices — or equipment with these functions — must not assume the category has quietly lapsed. Compliance status is a live variable to be checked against the current list rather than inferred from a product’s apparent obsolescence, and a business supplying into this space should verify the current position for its specific device rather than relying on assumptions. This discipline of confirming live status, rather than presuming exemption, is exactly what separates a smooth market entry from a consignment held at customs over a requirement the importer believed no longer applied.
