In summary, the Quality Assurance System (QAS) for NMPA certification plays a crucial role in ensuring the safety, quality, and compliance of medical devices throughout their lifecycle. Manufacturers must ensure compliance with ISO 13485, GMP, and other relevant standards. This includes the development of robust systems for design control, supplier management, documentation, corrective actions, and post-market surveillance. By establishing a comprehensive QAS, manufacturers can ensure successful NMPA certification and continued market success in China.
