CDSCO Inspectors Are Coming — Here Is Exactly What They Look For
What Happens During a CDSCO Inspection — A Complete Inside Guide That Nobody Has Written Before

Most medical device companies in India prepare for CDSCO inspections the wrong way.
They scramble. They pull together documentation at the last minute. They brief their team in the 48 hours before inspectors arrive. They treat the inspection as an event rather than as an outcome of everything they have been doing — or not doing — for the past year.
Then they wonder why they receive non-conformance observations.
A CDSCO inspection is not a surprise test. It is a structured, predictable, systematic review of your quality management system, your regulatory compliance, and your manufacturing operations. If you know what inspectors are looking for — and in what order they look for it — you can prepare properly, perform well, and walk away with a clean inspection report.
This article tells you exactly what happens during a CDSCO inspection, what inspectors prioritise, where companies fail most consistently, and what genuine inspection readiness looks like in 2026.
Why CDSCO Inspections Are Increasing in 2026
Before getting into the mechanics, it is important to understand the context.
CDSCO's inspection activity has increased significantly since MDR 2017 came into full effect. The regulator has expanded its inspection workforce, strengthened its inspection protocols, and increased the frequency of both scheduled and unannounced inspections across device classes.
Several factors are driving this increase. India's Production Linked Incentive scheme for medical devices has attracted new manufacturers — both domestic and foreign — who require pre-licensing inspections before their manufacturing license is granted. CDSCO's post-market surveillance mandate requires periodic inspections of licensed manufacturers to verify ongoing compliance. And growing international scrutiny of Indian-manufactured devices — particularly after several high-profile quality incidents involving Indian pharmaceutical and device products — has created regulatory and reputational pressure on CDSCO to demonstrate enforcement credibility.
The practical implication for manufacturers is that if you hold or are applying for a CDSCO manufacturing license, an inspection is not a theoretical possibility. It is an increasingly likely reality that you should be prepared for at all times.
The Three Types of CDSCO Inspections
Not all CDSCO inspections are the same. Understanding which type you are facing changes how you prepare.
Pre-Licensing Inspections
Before CDSCO grants a manufacturing license — particularly for Class C and Class D devices — a pre-licensing inspection of the manufacturing facility is conducted. This inspection focuses on whether the facility has the infrastructure, equipment, quality systems, and personnel to manufacture the specific devices for which the license is being sought.
Pre-licensing inspections are scheduled and you will have advance notice. This is the inspection where thoroughness of preparation pays the highest dividend — a clean pre-licensing inspection is the most direct path to your manufacturing license.
Surveillance Inspections
Licensed manufacturers are subject to periodic surveillance inspections to verify ongoing compliance with MDR 2017 requirements and the conditions of their license. Surveillance inspections may be scheduled or unannounced.
The frequency of surveillance inspections is risk-based — Class C and Class D manufacturers face more frequent inspections than Class A and Class B. A history of deficiency notices, complaint reports, or adverse event reports will increase your inspection frequency.
For Cause Inspections
These are triggered by a specific event — a serious adverse event report, a complaint about your device's safety or performance, a Materiovigilance report implicating your product, or intelligence about potential compliance violations. For cause inspections are almost always unannounced and focus specifically on the issue that triggered them.
Who Conducts CDSCO Inspections
For Class C and Class D devices, inspections are conducted by Central Licensing Authority — CLA — inspectors from CDSCO's central office. For Class A and Class B devices, State Licensing Authority — SLA — inspectors from the relevant state drug control authority conduct inspections.
CLA inspections are generally more rigorous and more technically detailed than SLA inspections, reflecting both the higher risk class of the devices being reviewed and the typically higher technical expertise of CLA inspectors.
An inspection team typically consists of two to four inspectors. For complex manufacturing operations or devices with significant software components, a specialist technical reviewer may accompany the inspection team.
What Inspectors Look at First — The Opening Meeting
Every CDSCO inspection begins with an opening meeting. This is not administrative formality — it sets the tone for everything that follows and experienced manufacturers use it strategically.
In the opening meeting, inspectors will introduce themselves and their scope, request your current license documents and license history, ask for your most recent management review records, request your organisational chart with key quality and regulatory personnel identified, and ask about any significant changes since your last inspection or license application — new products, new manufacturing processes, new suppliers, new personnel in key roles.
What inspectors are assessing in this first interaction is not just the documents you hand them. They are assessing your team's familiarity with your own quality system. A quality manager who can answer questions about recent management reviews, CAPA status, and audit findings without referring to notes projects a fundamentally different level of compliance confidence than one who has to search for basic documents.
Preparation tip: Brief your opening meeting team thoroughly. The quality manager, regulatory affairs lead, and production manager should all be present. Know your license details, your audit history, and your CAPA status before inspectors arrive.
The Document Review Phase — What They Request and Why
After the opening meeting, inspectors move into document review. This is typically the longest phase of the inspection and where the most common non-conformances are identified.
Quality Manual and Quality System Documentation
Inspectors will request your current Quality Manual and verify that it accurately describes your quality management system as actually implemented. The most common failure here is a Quality Manual that describes an ideal system rather than the actual system — discrepancies between what the manual says and what the shop floor does are a significant non-conformance.
Design History File
For manufacturers of Class C and Class D devices, the Design History File is scrutinised carefully. Inspectors look for evidence that your design and development process was controlled — design inputs documented, design outputs verified against inputs, design reviews conducted at appropriate stages, design verification and validation completed, and design changes managed through a controlled change management process.
Missing or incomplete Design History File documentation is one of the most consistently cited non-conformances in CDSCO inspection reports.
Risk Management File
Your ISO 14971 risk management file must be current and must cover your actual marketed product — not just your original design. If your device has undergone design changes since original risk assessment, inspectors will look for evidence that those changes triggered a risk management review.
Supplier and Vendor Documentation
CDSCO inspectors review your approved supplier list and your supplier qualification records. Critical component suppliers — those providing materials or components that directly affect device safety or performance — must be qualified through a documented process. Certificates of conformance and test results from critical suppliers must be on file and current.
A common failure in this area is maintaining an approved supplier list that has not been reviewed and updated to reflect actual current suppliers — situations where the approved list shows one supplier but purchase orders show a different one.
Complaint Handling Records
Your complaint files are reviewed carefully. Inspectors look for evidence that all complaints were received, documented, investigated, and closed appropriately. They specifically look for patterns — multiple similar complaints about the same device attribute that should have triggered a CAPA but did not.
CAPA Records
Corrective and Preventive Action records are among the most important documents inspectors review. They want to see that your CAPA system is genuinely functioning — that issues are being identified through multiple input sources, root causes are being properly investigated, corrective actions are being implemented and verified for effectiveness, and the system is preventing recurrence.
A CAPA system with many open CAPAs, CAPAs that have been open for extended periods without closure, or CAPAs that show superficial root cause analysis is a significant compliance signal.
The Facility Walk-Through — What They Look at on the Floor
After document review, inspectors conduct a physical walk-through of your manufacturing and quality control areas. This is where the alignment — or misalignment — between your documentation and your actual operations becomes visible.
Manufacturing Environment
For devices with specific environmental requirements — cleanroom classifications, temperature and humidity controls, particulate monitoring — inspectors verify that environmental controls are in place, functioning, and documented. Environmental monitoring records should be current and within specification.
Equipment Calibration and Maintenance
Every piece of measurement equipment used in manufacturing or quality control should be calibrated, with calibration records current and accessible. Equipment maintenance records should be maintained and show that scheduled maintenance is being performed.
Batch Records and Traceability
Inspectors will typically select one or more finished device batches and trace them backward through your manufacturing process — verifying that every step was performed as specified, that materials were from approved suppliers, that in-process and finished product testing was completed with results within specification, and that all required signatures and approvals are present.
This traceability exercise quickly reveals gaps between your documented procedures and your actual manufacturing practice.
Labelling Control
Labelling errors are among the most common causes of device recalls globally. Inspectors look for evidence that your labelling process is controlled — that only approved, current label versions are in use, that label issuance is documented, and that obsolete labels are removed from production areas.
The Closing Meeting — What Happens After the Walk-Through
At the end of the inspection, inspectors conduct a closing meeting where they present their preliminary findings. This is your opportunity to clarify factual misunderstandings, provide additional documentation that addresses observations, and demonstrate responsiveness to the inspection process.
Inspectors typically classify their findings into two categories. Observations are findings that represent departures from requirements but do not constitute critical violations. Critical findings are significant compliance failures that may require immediate corrective action or may affect the status of your license.
For observations — the more common outcome — you will typically be given a defined period to respond with a CAPA plan addressing each observation. A well-structured, technically credible CAPA response that demonstrates genuine understanding of the root cause and a realistic corrective action plan is almost always sufficient to close observations.
Critical findings require more immediate and comprehensive response and in some cases may trigger follow-up inspections to verify corrective actions.
The Ten Most Common CDSCO Inspection Failures
Based on inspection patterns across the Indian medical device industry, these are the findings that appear most frequently in CDSCO inspection reports.
Design History File incomplete or not reflecting design changes made after original documentation.
Risk management file not updated following design changes or post-market feedback.
CAPA system with aged open CAPAs and insufficient root cause analysis.
Supplier qualification records incomplete for critical component suppliers.
Environmental monitoring records with gaps or out-of-specification results not investigated.
Equipment calibration records not current for all measurement equipment.
Management review not conducted at required frequency or not addressing required inputs.
Internal audit program not covering all elements of the quality system at required frequency.
Complaint handling records with complaints not classified, investigated, or closed appropriately.
Labelling control with evidence of obsolete labels accessible in production areas.
If you can demonstrate robust, documented, current compliance with all ten of these areas, you are in the top tier of CDSCO inspection readiness in India.
Building Genuine Inspection Readiness
The difference between companies that pass CDSCO inspections cleanly and those that accumulate observations is not usually the quality of their preparation in the weeks before an inspection. It is the quality of their quality system operation throughout the year.
Genuine inspection readiness is not a pre-inspection sprint. It is a continuous state that results from a quality management system that is actually functioning — where management reviews happen on schedule, internal audits cover the full system, CAPAs are opened promptly and closed with verified effectiveness, and documentation is maintained as a live record of actual operations rather than reconstructed before each inspection.
Companies that achieve this state do not dread CDSCO inspections. They welcome them as an external validation of what they already know about their compliance status.
That is the standard to aim for.
