• User Manual: Provide a user manual with clear instructions for device use, maintenance, and safety information.

**7. Technical Review and Testing:

• Testing Reports: Submit reports of pre-market testing conducted to demonstrate compliance with safety and performance standards.
• Sample Submission: Provide samples of the device for NMPA testing or evaluation if required.

**8. Local Representation:

• Authorized Representative: Appoint a local authorized representative in China who will handle communication with the NMPA and ensure compliance with Chinese regulations.

**9. Regulatory Fees:
