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 |
| Class II registration (provincial) | 6–12 months |
| Class III registration (national/CMDE) | 12–24 months |
| Re-registration | 6–12 months |
Timelines vary significantly depending on dossier quality and supplemental information requests.

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.
