HSA Medical Device Classification

HSA applies 16 sets of rules to classify medical devices from lowest to highest risk into Class A, B, C, and D.

Risk classification depends on the factors like duration of contact, degree of invasiveness, intended use, and administration method.

Singapore Medical Device Authorized Representative / Registrant 

A Registrant is the liaison between your company and HSA, who handles the device registration listing in Singapore. Singapore medical device authorized representative processes the registration application with the HSA and owns your HSA device registration. Only Singapore-based companies or entities can act as a Registrant; they must also be registered with the HSA. 

HSA Medical Device Registration 

The HSA medical device registration process is conducted through the HSA online Medical Device Information and Communication system (MEDICS). Each HSA device registration is done via a specific evaluation route, depending on the following:

  • Risk classification of the device.
  • Number of prior approvals given by the overseas reference Regulatory agencies.
  • Duration of safety marketing history of the device.

The evaluation route of the device will determine the Turn-Around-Time (TAT), fees, and documents required for registration.

Class A Registration - Class A medical devices are exempted from product registration. However, there is a need to complete the Class A exemption list in MEDICS during the dealer’s license application.
