Product testing is not a formality — it is the scientific foundation of your CDSCO registration. Without valid, standards-compliant test data, your application will face queries, delays, or rejection. We help manufacturers and importers identify exactly what testing is required, source it from the right laboratories, and integrate it into a CDSCO-ready technical dossier.
Under the Medical Devices Rules (MDR), 2017, all medical devices must demonstrate safety, performance, and quality before being licensed for manufacture or import in India. Product testing is the primary mechanism through which this demonstration is made — and CDSCO guidance and regulatory expectations emphasize that testing requirements are critical for devices that come into contact with the human body.
Testing serves three specific regulatory functions in India:
Critical from CDSCO FAQ Addendum (April 2025): Biocompatibility testing is mandatory for medical devices that come into contact with the human body, in accordance with IS/ISO 10993. Failure to comply with these testing requirements could lead to regulatory delays, additional queries, or refusal of the application.
All medical devices that come into direct or indirect contact with the human body are generally expected to undergo biocompatibility evaluation in line with the IS/ISO 10993 series of standards.
Biocompatibility testing evaluates how your device interacts with tissues, cells, and biological systems. The extent of testing required depends on the nature, duration, and degree of body contact:
Contact Type | Examples | Key Biocompatibility Tests |
Surface contacting | Gloves, electrodes, dressings | Cytotoxicity, sensitization, irritation |
External communicating | Catheters, blood sets, endoscopes | Cytotoxicity, sensitization, haemocompatibility, genotoxicity |
Implantable devices | Bone screws, cardiac valves, stents | Full ISO 10993 matrix — cytotoxicity, sensitization, genotoxicity, implantation, chronic toxicity, carcinogenicity |
No human contact | Software, external diagnostic equipment | Biocompatibility testing may not generally be required |
Important 2025 update: Manufacturers may submit existing test data for similar devices — provided the materials, manufacturing processes, and intended use are the same. The submission must include a strong scientific justification along with a biological risk assessment. Additional testing may be required if there are significant changes in the device’s design or invasiveness.
Performance testing demonstrates that your device functions as intended — meeting the specifications and performance claims made in your registration application. This is device-category specific, but typically includes:
If a device complies with ISO/IEC standards, BIS standards must still be fulfilled where available. ISO/IEC standards apply only when BIS standards are not available. Where no BIS/ISO/IEC standard exists, the device shall conform to pharmacopoeial standards or validated manufacturer’s standards.
For all electrically powered medical devices, electrical safety and EMC testing is mandatory:
Testing must be conducted at NABL-accredited or CDSCO-recognized laboratories. Reports from internationally accredited labs (ILAC member bodies) are generally accepted by CDSCO where equivalent Indian standards exist.
Sterilization validation and parametric release are essential processes for medical devices that require sterilization before use, particularly for devices such as surgical instruments, implants, and other invasive medical devices. Manufacturers must ensure that the sterilization process is validated according to recognized international standards. Applicable standards include:
Parametric release may be accepted where supported by validated sterilization processes and appropriate documentation.
2025 Sterilization Outsourcing Update: The DTAB approved at its 92nd meeting on April 24, 2025 that medical device manufacturers no longer need to obtain a separate loan licence when outsourcing sterilization — provided they work with a facility already licensed under Form MD-3 or MD-9.
For sterile devices and devices with a defined shelf life, accelerated and real-time aging studies are required:
CDSCO clarification: For medical devices supplied in a non-sterile state, the date of expiry or shelf life on the label may not be necessary. This exemption does not apply to sterile devices.
For In-Vitro Diagnostic (IVD) devices, clinical performance evaluation is a specific and mandatory requirement under MDR 2017:
CDSCO has issued draft guidance relating to Medical Device Software to align software regulation more closely with globally harmonized practices, aiming to clarify specific regulatory requirements under MDR 2017 and align India’s approach with globally harmonized practices. For software-based devices, testing requirements include:
While not a “test” in the laboratory sense, risk analysis documentation is a mandatory submission requirement that must be based on and cross-referenced to your test data:
Your risk analysis and test reports must be consistent — risk controls claimed in the risk file must be validated by corresponding test data.
CDSCO requires that testing for medical device registration be conducted at recognized laboratories. A CMDTL (Central Medical Device Testing Laboratory) is a medical devices testing laboratory established or designated by the Central Government under Rule 19 of MDR 2017. Accepted testing sources include:
Laboratory Type | Accepted For | Notes |
CDSCO-notified testing laboratories | All CDSCO registration testing | Preferred by CDSCO — listed on CDSCO website |
NABL-accredited laboratories | Performance, electrical safety, EMC | National Accreditation Board for Testing and Calibration Laboratories |
BIS-approved laboratories | BIS IS standard compliance testing | Required where BIS standards exist |
ILAC member body accredited labs (international) | International test data for import applications | Generally accepted when equivalent Indian standards exist and testing scope matches |
Manufacturer’s own laboratory | In-house testing — some categories | Only accepted when laboratory meets prescribed standards — in-house data requires stronger scientific justification |
Critical note for importers: Test data generated for US FDA, EU MDR, or other global regulatory submissions is often acceptable to CDSCO — provided it covers the required parameters, was conducted at an accredited laboratory, and is submitted with appropriate scientific justification. Existing international testing data should be assessed carefully before commissioning additional testing.
if international data already exists. Assess what you have before commissioning new studies.

Issue | Impact | Prevention |
Wrong biocompatibility tests selected for contact type | CDSCO query — additional testing required | Build biocompatibility test matrix per ISO 10993-1 before commissioning any tests |
Testing conducted at non-CDSCO-recognized lab | Test data rejected — retesting required | Verify lab recognition before submitting samples |
Test report references older standard edition | CDSCO query on standards compliance | Always verify which standard edition is currently in force before testing |
Sterilization validation data missing or incomplete | Major query — sterility assurance level not established | Complete sterilization validation per applicable ISO standard before registration |
No biological risk assessment submitted with existing data | CDSCO may not accept existing biocompatibility data | Always pair existing test data with a formal biological risk assessment |
IVD performance data from outside India only | CDSCO requires India-specific performance data for Class B–D IVDs | Plan India performance evaluation early — it cannot be substituted with international data |
Software validation documentation missing | Post-October 2025 — CDSCO’s draft guidance has increased software scrutiny | Prepare IEC 62304 lifecycle documentation for any device with embedded software |
Risk analysis not cross-referenced to test data | Inconsistency between risk file and technical dossier — query raised | Build risk analysis and test plan together — not independently |
We assist manufacturers and importers at every stage of the testing process — from identifying what testing is required to integrating completed test data into your CDSCO registration dossier:
Identify exactly which tests are required for your specific device — by class, contact type, sterility, and intended use. Avoid commissioning unnecessary tests and ensure no mandatory test is missed.
Prepare a complete IS/ISO 10993 biocompatibility evaluation matrix for your device — identifying which tests apply and whether existing data can be leveraged with appropriate biological risk assessment.
Identify the right CDSCO-recognized, NABL-accredited, or BIS-approved laboratory for each test type — ensuring your data will be accepted by CDSCO without challenge.
Review your existing test data — from US FDA, EU MDR, or other global submissions — to determine what is acceptable to CDSCO and what gaps remain. Avoid unnecessary retesting.
Advise on sterilization validation strategy — including EO, gamma, steam — and review your sterilization validation documentation against ISO 11135, 11137, and 17665 requirements for CDSCO submission.
Prepare IEC 62304 software lifecycle documentation, cybersecurity risk assessments, and algorithm change protocols for SaMD and SiMD devices — per CDSCO’s October 2025 draft guidance.
Prepare a complete, test-data-integrated risk analysis per ISO 14971 — ensuring your risk file and technical dossier are consistent and cross-referenced throughout.
If CDSCO raises testing-related queries on your application, we prepare complete, evidence-backed responses — addressing every technical point and sourcing supplementary data where needed.
Can I use test data from my US FDA or EU MDR submission for CDSCO registration?
Often yes — CDSCO generally accepts test data from internationally accredited laboratories, provided the tests were conducted to the applicable standards and cover the required parameters. However, you must submit a biological risk assessment alongside any reused biocompatibility data, and India-specific performance evaluation may be required for IVD devices. We assess your existing data package to identify exactly what is reusable and what gaps remain.
Does my device need a Test Licence (MD-13) before applying for a manufacturing licence?
The validation and quality control data generated by a manufacturer for a medical device marketed in the country prior to implementation of the mandatory licensing regime under MDR 2017 can be considered for grant of a manufacturing licence — if found satisfactory by the Licensing Authority. In such cases, a Test Licence in Form MD-13 is not mandatory. For new devices without prior India market history, a Test Licence is typically obtained to generate performance and safety data before the full manufacturing licence application.
Which laboratory should I use for biocompatibility testing in India?
Biocompatibility testing should be conducted at a CDSCO-notified or NABL-accredited laboratory. We maintain an updated list of recognized laboratories for different test categories and can recommend the appropriate lab based on your device type, test requirements, and timeline. International lab data from ILAC member body accredited labs is generally accepted when the testing scope aligns with CDSCO requirements.
My device has software — what additional testing does CDSCO require?
CDSCO released a draft guidance document on Medical Device Software in October 2025, aligning India’s framework with EU MDR and IMDRF guidance. Software-containing devices now require IEC 62304 lifecycle documentation, a cybersecurity risk assessment, and — for AI/ML-based devices — an Algorithm Change Protocol (ACP). For SaMD classified as Class C or D, full software validation and risk management documentation is mandatory.
Do I need sterilization validation if I outsource sterilization?
As per DTAB’s 92nd meeting (April 24, 2025), medical device manufacturers no longer need to obtain a separate loan licence when outsourcing sterilization — provided the sterilization facility already holds a valid MD-3 or MD-9 licence. However, the sterilization process must still be validated per applicable standards (ISO 11135, 11137, or 17665), and the validation data must be available for submission with your registration application.
How long does medical device testing take?
Testing timelines vary significantly by test type. Biocompatibility testing typically takes 4–12 weeks depending on the studies required. Sterilization validation can take 8–16 weeks. Accelerated aging (shelf life) runs 8–26 weeks depending on claimed shelf life. Electrical safety and EMC testing typically takes 4–8 weeks. Planning testing in parallel with documentation preparation — not after it — is critical to minimizing overall registration timelines.
Device testing is where most CDSCO registration timelines are significantly impacted. Getting the test plan right — identifying required tests, selecting the right labs, and integrating data into your dossier — determines whether your application moves quickly or gets stuck in query cycles.
