Hi All,
Please note that the guidance document GN-22 had been updated to 6.2. You can find the most up-to-date guidances at their website.
You will be able to see that they had removed the HS codes from the guidance. That be because HS codes are determined by the Customs Authority and not the Medical Device regulating authority. Following the list in the original guidance may not be 100% accurate, but it is definitely a good reference
It is also important to note that the list is only a suggestion and it all comes down to whether you product is classified as a Class A device that is non-sterile according to Singapore Medical Device Regulations.
To add onto what Sweetasheaven said, the importer will require an Importer licence from the local Authority for importing. The list of Class A non-sterile medical devices must be declared to the Authority as part of the importer licence.
