Which of the following is exempt from GMP/QSR regulations?

The correct choice pertains to component manufacturers being exempt from Good Manufacturing Practice (GMP) or Quality System Regulation (QSR) requirements in certain situations. Component manufacturers supply parts or materials that are used in the production of finished medical devices, but they are generally not subject to the same stringent regulations that govern the manufacturers of finished devices.

This exemption exists because component manufacturers do not engage in the actual production and assembly of the final product. Instead, they provide the necessary parts that are incorporated into devices that ultimately reach the market. As a result, while the overall device must adhere to GMP/QSR standards, the individual components may not be required to meet the same regulatory scrutiny unless specifically involved in critical aspects of product safety or efficacy.

In contrast, remanufacturers, custom device manufacturers, and repackagers are typically subject to GMP/QSR regulations because they are more directly involved in the production and handling of medical devices. These roles involve processes that can significantly affect the quality and safety of the final medical device, thus necessitating regulatory oversight to ensure compliance with the established standards.
