Yes, medical devices do require additional import licenses for sale in China, in addition to obtaining NMPA certification. Here are the key licenses and permits typically required:

1. Medical Device Registration Certificate (NMPA Certification): This is the primary license required to legally import and sell medical devices in China. It ensures that the device meets Chinese regulatory standards for safety, quality, and efficacy.

2. Import License: Importers need to obtain a separate import license from the General Administration of Customs of China (GACC). This license allows the importation of goods into China and is necessary to clear customs and bring the medical devices into the country.

3. Medical Device Manufacturing License (if applicable): If the medical device is manufactured in China, the manufacturer must hold a Medical Device Manufacturing License issued by the NMPA. This license is required for production and sale within China.

4. Business License: Importers and distributors must have a business license in China to operate legally. This includes entities such as foreign-invested enterprises (FIEs), representative offices, or joint ventures.

5. Additional Permits: Depending on the specific type of medical device and its classification, additional permits or approvals may be required. For example, certain high-risk devices may need special clinical trial approvals or special use permits.

It's essential for importers and manufacturers to ensure they have all necessary licenses and permits in place before importing medical devices into China to comply with local regulations and facilitate smooth market entry.
