CDSCO Licence for Endotracheal Tubes in India: Class B Registration, ISO 5361 and Process

An endotracheal tube secures a patient’s airway during anaesthesia and critical care, delivering ventilation directly to the trachea. Because it is inserted into the airway and often has an inflatable cuff, CDSCO regulates the endotracheal tube as a Class B device with the tracheal-tube standard, cuff performance and sterility behind the licence. This guide covers the full CDSCO registration pathway for endotracheal tubes under the Medical Devices Rules, 2017 — classification, licence route, ISO 5361, the documents, the fees and the timeline. This guide explains CDSCO registration for endotracheal tubes in India — risk class, licence forms, standards, documents, fees and timeline.

Is a CDSCO Registration Mandatory for Endotracheal Tubes?

Yes. An endotracheal tube is a notified Class B medical device and cannot be manufactured, imported or sold in India without a CDSCO licence. A domestic manufacturer holds a Form MD-5 licence from the State Licensing Authority. An importer holds a Form MD-15 import licence through an Indian Authorised Agent. Cuffed and uncuffed tubes, and related airways (LMAs, oropharyngeal airways), fall within the framework.

Risk Classification of Endotracheal Tubes

Every medical device in India falls into one of four risk classes (A, B, C, D) under the First Schedule of the Medical Devices Rules, 2017. The class fixes the authority, the form, the fee, the audit route and the timeline.

Endotracheal Tubes are classified as Class B (low-to-moderate risk). An endotracheal tube is a surgically invasive device introduced into the airway to sustain ventilation, placing it in Class B (low-to-moderate risk) under the First Schedule. Where a device could fall in two classes the higher class applies, and an accessory is classified in its own right. Always confirm against the current CDSCO classification list.

Which CDSCO Licence You Need for Endotracheal Tubes

To manufacture endotracheal tubes in India (Class B) — apply in Form MD-3 to the State Licensing Authority (SLA). The licensing authority grants the licence in Form MD-5. A CDSCO-empanelled Notified Body audits the site. For Class A the audit is post-grant. For Class B the Notified Body conducts it before the licensing authority grants the licence.
To import endotracheal tubes (any class) — the overseas manufacturer appoints an Indian Authorised Agent who files Form MD-14 with the Central Licensing Authority; CDSCO grants the import licence in Form MD-15.
Test licence — for a small quantity imported or made for testing, evaluation, demonstration or clinical investigation: Form MD-12 application, Form MD-13 licence.
Loan licence — using another licensee’s approved premises: Form MD-4 (Class A/B) or Form MD-8 (Class C/D) for a licence in Form MD-6 or MD-10.

Applicable Standards for Endotracheal Tubes

Endotracheal tubes are evaluated against the tracheal-tube standard plus cuff performance and sterility:

ISO 5361 — anaesthetic and respiratory equipment: tracheal tubes and connectors.
Cuff pressure/volume and seal performance for cuffed tubes.
ISO 5356 / connector conformity for the 15 mm connector.
ISO 10993 series — biocompatibility of the tube and cuff.
ISO 11135 / 11137 — sterilisation validation.
Radiopacity and Murphy-eye features as applicable.

Documents Required for CDSCO Registration of Endotracheal Tubes

Whether you file for a manufacturing or an import licence, CDSCO expects the same core technical dossier built around the device:

Covering letter and application form — Form MD-3 / MD-7 (manufacture) or Form MD-14 (import) on the CDSCO Medical Device Online portal, stating every device, variant and site.
Device Master File (DMF) — device description and intended use, materials, design and manufacturing information, ISO 14971 risk file, verification/validation data, sterilisation validation where applicable, shelf-life/stability data and the Essential Principles checklist.
Plant Master File (PMF) — site layout, equipment, utilities/HVAC, organisation chart with competent technical staff and the QMS procedures governing production.
ISO 13485 QMS certificate — current, with a scope covering the device.
Essential Principles of Safety and Performance — a completed checklist mapping the device against each applicable principle with the standard/evidence relied on.
Risk management file (ISO 14971) — hazards, risk controls and residual-risk justification.
Test / performance reports — against the applicable BIS/IS or ISO/IEC standards from an accredited laboratory.
Labels, IFU and packaging — meeting the labelling requirements of the Medical Devices Rules (manufacturer, licence number, sterile status, single-use symbols).
Undertaking and declaration of conformity to the Essential Principles and applicable standards.
Government fee receipt — paid online through the CDSCO portal.

Device-Specific Documents for Endotracheal Tubes

Device-specific documents on top of the core set for endotracheal tubes:

ISO 5361 test reports — dimensions, kink resistance, connector security and radiopacity.
Cuff performance data — inflation/deflation, seal and residual-volume for cuffed tubes.
Sterilisation validation with the sterility assurance level (SAL 10⁻⁶).
Biocompatibility (ISO 10993) for the tube and cuff.
Connector conformity (ISO 5356).
Country-of-origin approval / Free Sale Certificate for imports.

For an import licence (Form MD-14) there are three further essentials:

Free Sale Certificate (FSC) — from the National Regulatory Authority of the country of origin, legalised (apostille/embassy attestation).
Country-of-origin regulatory approval — US FDA 510(k)/PMA, EU CE certificate or equivalent.
Power of Attorney and Authorised Agent licence — notarised, legalised PoA to the Indian Authorised Agent, plus the agent’s valid wholesale/manufacturing licence.

QMS & Essential Principles — What CDSCO Checks

Essential Principles of Safety and Performance (Fifth Schedule) — the device must be safe and perform as intended, with risks reduced as far as possible. Shown through recognised standards and the risk-management file.
Quality Management System (ISO 13485) — design controls, supplier control, process validation, traceability, complaint handling and CAPA, evidenced at audit.
Risk management (ISO 14971) — a living file with residual risks justified and communicated in the IFU.
Clinical evidence — proportionate to the class: clinical evaluation for lower-risk devices and clinical investigation data for many Class C/D and novel devices.

Label & IFU Requirements Specific to Endotracheal Tubes

Endotracheal-tube labelling is checked for size, cuff and sterility:

Internal diameter (ID mm), cuffed/uncuffed and the reference number.
Manufacturer name and address, and the CDSCO licence number.
Batch/lot number, date of manufacture and use-by date.
“STERILE” with the sterilisation-method symbol and a single-use symbol.
Radiopaque line, depth markings and cuff-inflation information in the IFU.

Cuffed vs Uncuffed, and Related Airways

Endotracheal tubes split into cuffed (with an inflatable seal, common in adults) and uncuffed (often paediatric) types, and the cuff performance — pressure, seal, residual volume — is specific evidence for cuffed tubes. The airway family also includes laryngeal mask airways (LMAs) and oropharyngeal airways, which have their own standards. Decide which airway devices and sizes you are registering, and evidence the cuff for cuffed tubes. This keeps the tested product matched to the sold product.

Step-by-Step CDSCO Registration Process for Endotracheal Tubes

Confirm the classification. Fix the risk class against the CDSCO classification list and the First Schedule — Class B here — which decides the form, authority, fee and audit route.
Choose the route. Manufacture (Form MD-3 → MD-5) or import (Form MD-14 → MD-15). Importers appoint an Indian Authorised Agent holding a valid manufacturing or wholesale licence.
Build the Device Master File and Plant Master File. Assemble device description, materials, design and process data, the ISO 14971 risk file, sterilisation/stability data and the site file with the QMS.
Complete the Essential Principles checklist. Map the device against each applicable essential principle and cite the BIS/IS or ISO/IEC standard or test report relied on.
Draw the test and performance reports. Test to the applicable standards at an accredited laboratory. Sterile and measuring devices carry additional validation.
Register and file on the CDSCO Medical Device Online portal. Create the account, pay the government fee online and upload the full dossier under the correct form.
Site audit / inspection. A CDSCO-empanelled Notified Body audits the site. For Class A the audit is post-grant. For Class B the Notified Body conducts it before the licensing authority grants the licence.
Respond to queries and receive the licence. Answer the deficiency letter within the stipulated period. On approval the licence issues in Form MD-5 (manufacture) or MD-15 (import).

CDSCO Registration Fees and Timeline for Endotracheal Tubes

The Second Schedule of the Medical Devices Rules sets the fees, and you pay them online through the CDSCO portal. For manufacture of a Class B device the fee is Rs 5,000 per site plus Rs 500 for each distinct device, paid to the State Licensing Authority (SLA). CDSCO charges import fees under Form MD-15 per site and per device in USD — roughly USD 1,000 per site plus USD 50 per device for lower-risk devices, up to about USD 3,000 per site plus USD 1,500 per device for Class C and D. A test licence (Form MD-13) carries a modest fee. Always confirm the current figure on the CDSCO portal before filing.

A complete Class B manufacturing file typically clears in about three to six months. An import (MD-15) file usually takes six to nine months. Every deficiency letter effectively restarts the clock. Unlike the old registration certificates, an MDR 2017 licence does not expire — it stays valid as long as you pay the retention fee (equal to the licence fee) every five years and meet the conditions of licence.

Common Mistakes That Trigger a CDSCO Query

Common query reasons for endotracheal-tube applications are:

Cuff performance (pressure/seal/residual-volume) data missing for cuffed tubes.
Connector security/conformity (ISO 5356) not evidenced.
Sterilisation validation absent or not matching the cycle.
Biocompatibility not covering the airway-contact duration.
Free Sale Certificate scope not covering all sizes on import.

Related Approvals to Plan Alongside CDSCO

DGFT Importer-Exporter Code — mandatory for any importer of record before the first consignment.
Wholesale / sale licence (Form 20B/21B or Form MD-42) — for stocking and distributing the device. The Indian Authorised Agent for an import licence must already hold one.
Legal Metrology (LMPC) registration — importers of pre-packaged devices declare MRP, net quantity, importer details and country of origin on the pack.
BIS certification — where the device or its electrical components fall under a mandatory BIS/CRS scheme.

Post-Approval Obligations

Print the licence number on the label and keep the Essential Principles conformity current.
Operate a Post-Market Surveillance (PMS) system and file the Periodic Safety Update Report (PSUR) on the schedule for the device’s class.
Report adverse events and field safety corrective actions through the Materiovigilance Programme of India (MvPI) and to CDSCO within the prescribed timelines.
Report any change in device, materials, site, labelling or QMS, and any regulatory action or recall in another country.
Retain distribution records for traceability and allow CDSCO to draw samples and inspect the premises.
Pay the retention fee every five years to keep the licence in force, and track BIS/ISO standard revisions.

FAQs on CDSCO Registration for Endotracheal Tubes
