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 labelling requirements
   └─ Register in NMPA UDI database (UDID) — phased by class
   └─ Distributor obtains Business Licence if Class II/III

7. POST-MARKET OBLIGATIONS
