The inspection requirements for NMPA certified medical devices in China typically involve two main types of inspections: initial inspections and post-market inspections.

1. Initial Inspections

Initial inspections are conducted as part of the NMPA certification process, especially for higher-risk devices (Class II and III). These inspections aim to verify compliance with quality management system (QMS) requirements and ensure that the manufacturing facilities meet Chinese regulatory standards. Key aspects include:

• Site Visit: NMPA inspectors may visit the manufacturing facilities to assess:
  • Production processes and controls
  • Quality assurance procedures
  • Calibration and maintenance of equipment
  • Personnel training and qualifications
• Documentation Review: Inspectors review QMS documentation to ensure alignment with ISO 13485 or equivalent standards. This includes:
  • Document control procedures
  • Records of design, manufacturing, and testing
  • Corrective and preventive actions (CAPA)
  • Supplier control and material traceability
• Sample Testing: Random samples of the medical device may be tested to verify compliance with technical specifications and safety standards.

2. Post-Market Inspections

Post-market inspections occur after a medical device has been placed on the market. These inspections are conducted to monitor ongoing compliance with NMPA regulations and ensure device safety and performance. Key aspects include:

• Sampling: Inspectors may select devices from the market for testing to verify compliance with specifications and standards.

• Adverse Event Reporting: Manufacturers are expected to report adverse events and device malfunctions. Inspectors may review these reports during inspections to assess how effectively issues are managed.

• Compliance Checks: Inspectors verify that the marketed devices continue to meet QMS requirements and adhere to approved specifications.

Key Considerations

• Frequency: The frequency of inspections varies based on device classification and risk. Higher-risk devices typically undergo more frequent inspections.

• Notification: Manufacturers are usually notified in advance of an inspection, allowing time to prepare relevant documentation and facilities.

• Non-Compliance: If non-compliance is found during an inspection, corrective actions may be required. Serious violations can lead to regulatory sanctions, including suspension or revocation of the registration certificate.

Navigating inspection requirements is critical for maintaining NMPA certification and ensuring ongoing compliance with Chinese regulatory standards for medical devices. Staying proactive with quality management practices and maintaining accurate records are essential components of a successful inspection process.
