Frequently asked questions
Hong Kong medical device classification FAQ
How are medical devices classified in Hong Kong?
MDD uses a risk-based framework. General-device classes I–IV with a separate IVD framework. The applicable class depends on the product's intended purpose, duration of use, invasiveness, active functions, implantability, sterility, software role, and other market-specific rules.
Is this Hong Kong medical device classification tool free?
Yes. The preliminary MDD classifier is free to use and does not require an account. Fair-use limits help keep it available to everyone.
What information does the Hong Kong classifier use?
Current MDD requirements and class information from similar registered products. Your result includes an explanation and links to the official sources used.
Is the result an official MDD classification decision?
No. The result is a preliminary estimate based on the product details you provide and the information available. Confirm the classification with the applicable authority or a qualified regulatory professional before filing.
