Despite its small geographic size, Singapore has one of the largest and most advanced healthcare systems in the world. Singapore has robust healthcare infrastructure, so there is consistent demand for state-of-the-art medical technologies. Medical devices in Singapore are regulated by the Medical Device Branch of the Health Sciences Authority (HSA). Singapore is a member of the Association of Southeast Asian Nations (ASEAN) and its regulatory system is based on the Health Products Act 2007 and Health Products (Medical Devices) Regulations 2010. These regulations dictate how medical devices are classified in Singapore and the registration routes for each class.Device classification in Singapore is based on a four-tier system (Class A, B, C, and D), with Class A assigned to the lowest-risk products and Class D assigned to the highest-risk products. Devices with prior authorization in the US, Europe, Canada, Australia, or Japan are eligible for abridged evaluation routes.
