How often is a manufacturer required to re-register with the DEA?

A manufacturer is required to re-register with the DEA every three years, not annually. This is essential to ensure that the manufacturer still complies with all regulatory requirements, including producing controlled substances safely and securely. The DEA mandates these renewals to help maintain oversight of the manufacturing of controlled drugs, reducing potential misuse and ensuring that the industry adheres to federal regulations.

Although the selected answer was "every year," the proper frequency of re-registration is every three years, which is vital to ensure that both the manufacturer and the DEA have updated information, allowing for effective monitoring and enforcement in the pharmaceutical industry.
