The core process for NMPA certification involves several key steps:

1. Classification: Determine the device's classification (Class I, II, or III) based on risk level, which dictates the requirements.

2. Dossier Preparation: Compile a comprehensive registration dossier, including technical documentation, labeling, and clinical data if required.

3. Clinical Trials: For Class II and III devices, conduct clinical trials in accordance with NMPA guidelines to validate safety and efficacy.

4. Application Submission: Submit the registration application to the NMPA along with all required documents and fees.

5. Technical Review: NMPA conducts a thorough review of the submitted documents and may request additional information or modifications.

6. On-site Inspection: For Class II and III devices, an on-site inspection of the manufacturing facility may be required to ensure compliance with GMP.

7. Approval and Certification: Upon successful completion of the review and inspection, NMPA issues a registration certificate, allowing the device to be marketed in China.

8. Post-market Surveillance: Manufacturers must monitor device performance and report any adverse events to NMPA.
