Will Class III medical devices be automatically cancelled when they expire?

You can't. The validity period of the business license for Class III medical devices is 5 years, which can be extended after the expiration. The extension period is 10 to 15 working days. If the license is unqualified after rectification, or causes serious consequences in monitoring and spot check, the food and drug supervision and administration department will cancel the license and notify the local administrative department for industry and commerce, so the three types of medical devices will not be automatically cancelled when they expire.
