Supplier qualification is an element in the U.S. current Good Manufacturing Practice regulation for dietary supplements (21 CFR Part 111). Proper supplier qualification across the dietary supplement industry is critical for maintaining integrity of the supply chain and reducing or preventing economically motivated adulteration. To assist with supplier qualification activities, the SIDI Work Group developed a series of voluntary guidelines to serve as resources for the dietary supplement industry.  


Access these guidelines free of charge on this website after a brief free registration, or log in if you've already registered.
