Medium Risk Class II and High Risk Class III medical devices are subject to a registration process with applications and supporting documentation submitted to the CFDA. Product testing certificates issued from a (local) CFDA-certified laboratory are a required element of the application. Local clinical test data is also required for most Class II and III devices.
