Lifecycle of a Medical Device in China

The regulatory lifecycle of a medical device in China follows a predictable sequence. Understanding the full lifecycle before you begin helps you plan resources, timelines, and costs effectively.

Lifecycle stages

1. CLASSIFY THE DEVICE
   └─ Determine Class I, II, or III using NMDCC
   └─ Determine if IVD rules apply

2. PRE-SUBMISSION PREPARATION
   └─ Compile technical dossier (performance testing, biocompatibility, clinical evidence)
   └─ Establish QMS / GMP compliance
   └─ Appoint China Agent (if overseas manufacturer)

3. REGISTRATION OR FILING
   └─ Class I: file with district/county authority
   └─ Class II: register with provincial NMPA bureau
   └─ Class III / imported: register with national NMPA (CMDE review)

4. PRE-APPROVAL INSPECTION (Class III domestic)
   └─ NMPA GMP inspection of manufacturing site before certificate issued

5. CERTIFICATE ISSUED
   └─ Valid for 5 years
   └─ Certificate lists device name, model, specifications, registrant, China Agent

6. MARKET ENTRY
└─ Comply with Chinese language labelling requirements (see MDSAR 2021 Article 51)
└─ Register device in NMPA UDI database (UDID) within specified timeline: Class III within 6 months; Class II by end of 2025; Class I phased through 2026
└─ Distributor registration: Class II/III devices may only be distributed through wholesalers/retailers holding required business licenses; Class I has fewer restrictions

7. POST-MARKET OBLIGATIONS
   └─ Adverse event monitoring and reporting
   └─ Annual self-assessment report (registrant)
   └─ PMS plan execution, complaint handling
   └─ Co-operate with NMPA surveillance inspections

8. CHANGE MANAGEMENT
   └─ Notify NMPA of significant changes (change supplement 变更申请)
   └─ Some changes require re-registration

9. RE-REGISTRATION (重新注册)
   └─ Certificate renewal required every 5 years
   └─ Begin process at least 6 months before expiry

Typical timelines

Stage	Indicative timeline
Class I filing	1–3 months

UDI Registration: Devices must be registered in NMPA's UDI Database (UDID) within specified timeframe (Class III: within 6 months of registration; Class II: by 2025; Class I: phased implementation). Failure to register affects sales permissions.

Timelines assume: (1) complete and compliant initial dossier; (2) no supplemental information requests (SIR); (3) no major quality or safety issues identified during review. Class III devices typically experience 1–3 rounds of supplemental requests, adding 3–6 months per round.
