The NMPA registration process for Class II medical devices in China involves multiple steps, including document preparation, clinical and performance testing, submission of an application, and review by the NMPA. For foreign manufacturers, an authorized agent is required to manage the registration process. Given the complexities of the process, especially for higher-risk devices, it is highly recommended to work with local experts to navigate the regulatory landscape effectively. The process generally takes between 6 to 12 months, and costs can vary based on the device and its specific requirements.
