Hi..
Your Importer has to do following in sequence:
1. Open CRIS Administrator account with HSA(
www.hsa.gov.sg)
2. The register as a "Registrant".(ACRA business license is reqd)
3. Appoint a 3rd Part Certification body (list is in
http://www.sac-accreditation.gov.sg/) to do GDPMDS Certification Audit.
4. After obtaining GDPMDS certificate, prepare the documentation(guidance from HSA website; Site Master File, SOPs-complaint handling, control of docs, control od records, distribution records, traceability, FSCA, handling,storage, training of personnel, records, etc..) and list of devices with its class and submit to HSA via MEDICS account (once u get CRIS user name and pswd, u can be able to access MEDICS).
5. Mention what ever applicable (Importer or Wholesaler).
6. That's all
Cheers
