The US Food and Drug Administration (FDA) published its proposed rule National Standards for the Licensure of Wholesale Drug Distributors and Third-Party Logistics Providers on February 4, 2022. The proposed rule sets national standards for the licensing of prescription drug wholesale distributors (WDDs) and third-party logistics providers (3PLs) with the goal of strengthening the security of the US drug supply chain. When finalized and effective, these licensing regulations will pre-empt state and local licensing standards, requirements and regulations that are different from these federal requirements.
