What is a requirement for verifying trading partners under the Drug Supply Chain Security Act?

The requirement for verifying trading partners under the Drug Supply Chain Security Act (DSCSA) is centered around ensuring that all entities in the supply chain are legitimate and can safely handle pharmaceutical products. Holding valid licenses is crucial because it verifies that the trading partners are authorized to operate within the pharmaceutical supply chain. This means they meet specific state and federal regulatory requirements, ensuring that they adhere to standards of safety, quality, and security in handling and distributing medications. A valid license signifies compliance with legal obligations, which is key to preventing counterfeit drugs from entering the market and maintaining the integrity of the drug supply chain.

The other options do not reflect the core requirements set forth by the DSCSA. For instance, being based in the same state, providing a drug testing guarantee, or offering discounts on bulk purchases do not address the essential regulatory aspects necessary for ensuring public safety and maintaining the quality of pharmaceuticals in the supply chain.
