The geographical coverage of China NMPA (National Medical Products Administration) certification primarily applies to the People's Republic of China. This means that devices certified by the NMPA are approved for sale and distribution within mainland China, including Hong Kong and Macau. However, the certification does not automatically extend to other countries or regions.

If you intend to market your medical device outside of China, you would typically need to obtain separate certifications or registrations according to the regulatory requirements of those specific countries or regions. This often involves complying with their respective regulatory frameworks, submitting relevant documentation, and sometimes undergoing additional testing or assessments.

It's important to note that some countries or regions may have mutual recognition agreements or harmonization agreements with China, which can facilitate the acceptance of NMPA certifications to varying degrees. However, these agreements are specific and may not cover all types of medical devices or regulatory aspects.

Therefore, while China NMPA certification is essential for accessing the Chinese market, it's crucial to research and comply with the regulatory requirements of each target market to ensure lawful distribution and sales of your medical devices internationally.
