HSA Singapore Medical Device Classification and Grouping

HSA Singapore medical device classification rules

Medical devices in Singapore are classified based on their level of risk, ranging from Class A (low risk) to Class D (high risk). The classification rules are adopted by HSA from the guidance developed by the Global Harmonization Task Force (GHTF), and they determine the regulatory requirements, and the level of scrutiny devices undergo during the registration process.

The classification rules are based on the expected purpose of the equipment, as well as factors such as usage time, invasiveness in the body, or energy transfer. Before confirming the risk level, all rules should be considered. If there are two or more rules relevant to the device, it will be classified at the highest level. To review the classification rules, refer to GN-13: Guidance on the Risk Classification of General Medical Devices.

Singapore Medical Device classification tiers

Class A devices are exempt from product registration, while applicable dealer licensing, Class A notification/listing and safety duties remain. Use the current SHARE service and GN-22 requirements; exemption from registration is not permission to bypass the local supply controls.

Class B requires the registrant to submit an application, and based on the market authorization obtained, the application path is Full, Abridged, or Immediate. Low- to moderate-risk devices include syringes, surgical gloves, and hearing aids.

Class C requires the registrant to submit an application. Full, abridged or expedited evaluation may be available when the precise eligibility conditions are met. Immediate registration for Class C is restricted to eligible standalone medical mobile applications; it is not a general route for Class C hardware. Examples must be checked against the actual rule: implantable pacemakers are Class D, not Class C. Active therapeutic devices and implants can fall into different classes depending on their function and risk.

Class D requires the registrant to submit an application. Based on the market authorization obtained, the application path is Full, Abridged, or Expedited. High-risk devices include heart valves, drug-eluting stents, and advanced diagnostic imaging equipment.

Medical device grouping in Singapore

Grouping of medical devices allows for multiple products to be submitted under a single registration. According to GN-12-1: Guidance on Grouping of Medical Devices for Product Registration, devices can be grouped as a family, system, IVD test kit, IVD cluster, or group. However, there are different rules for each group type. For example, a family may include products from the same manufacturer that also share the same intended purpose, among other characteristics. A system, however, is a group of products from the same manufacturer that are designed to be used together to achieve the intended purpose.

Classification record and filing handoff

Prepare a short, reviewable rationale before commissioning a dossier. It should identify the product owner, intended medical purpose, patient population, user, duration and nature of body contact, active function, and consequence of an incorrect result. Use GN-13 for general devices and GN-14 for IVDs, with relevant software guidance where applicable. IVD classification considers both individual and public-health risk; it is not determined solely by the instrument used.

Record the selected rule, competing rules considered, final A–D class and evidence supporting the conclusion. Apply the highest applicable rule where required. Then use the Singapore registration pathway guide to assess evidence and route eligibility. HSA's current guidance library supplies the controlling revisions, rather than a classification example copied from another market.
