CDSCO Inspection Checklist for Manufacturing Sites — Complete Compliance Guide for Medical Device Manufacturers

 Medical device manufacturing in India is regulated under the Medical Devices Rules, 2017 (MDR 2017), administered by the Central Drugs Standard Control Organisation (CDSCO). Before granting or renewing a manufacturing licence, CDSCO and State Licensing Authorities may conduct inspections of manufacturing facilities to verify compliance with regulatory, quality, and safety requirements.

A CDSCO inspection is one of the most critical stages in the medical device approval process. Manufacturers must demonstrate that their facility, processes, documentation, quality systems, and product controls comply with MDR 2017 and applicable quality management standards such as ISO 13485.

Failure to meet inspection requirements may lead to:

• Delay in licence approval
• Regulatory observations
• Suspension of applications
• Product recalls
• Warning notices
• Cancellation of licences

Understanding the CDSCO inspection checklist for manufacturing sites is therefore essential for every medical device manufacturer operating in India.

Qualified technical personnel are mandatory under MDR 2017 manufacturing requirements.

6. Production and Process Controls

Production operations are closely reviewed during inspections.

Inspectors generally evaluate:

• Manufacturing process flow
• Batch manufacturing records
• In-process controls
• Process validation reports
• Sterilization validation
• Packaging controls
• Final release procedures

Manufacturers must demonstrate consistency, traceability, and process control throughout production activities.

7. Raw Material and Supplier Control

Raw material quality directly affects medical device safety and performance.

Inspectors commonly verify:

• Approved vendor lists
• Incoming material inspection records
• Supplier qualification systems
• Material traceability
• Storage conditions

Poor supplier control is considered a major compliance risk during regulatory inspections.

8. Device Master File (DMF) Review

The Device Master File is one of the most important technical documents reviewed during inspections.

The DMF generally contains:

• Device description
• Intended use
• Product specifications
• Design information
• Manufacturing process details
• Risk analysis
• Verification and validation data
• Labeling and IFU
