Ingredient Verification Program

Properly qualifying suppliers is a growing challenge across all industries, especially as global supply chain disruptions continue. However, these disruptions do not have to mean compromising quality. USP’s Ingredient Verification Program (IVP) helps ensure the quality of active pharmaceutical ingredients (APIs), excipients, and dietary ingredients, in addition to qualifying new suppliers.

For ingredient suppliers, USP Verification makes the quality of your ingredients visible by:

  • Demonstrating quality of ingredients to customers, while differentiating them in an increasingly competitive global market
  • Helping ensure uniformity with Good Manufacturing Practices (GMP) and science-based quality standards, including product standards that are required by law within the U.S.
  • Reducing supplier qualification burden by decreasing the number of customer audits
  • Issuing independent test reports for verified ingredients

For drug product and dietary supplement manufacturers, USP Verification mitigates risk to your supply chain by accomplishing the following:

  • Lowers the risk of inconsistent and substandard quality ingredients
  • Supports the qualification of new ingredient suppliers when changing an API, excipient, or dietary ingredient supply source
  • Builds confidence in ingredient quality, while reducing inspection costs
  • Can help to develop reduced testing requirements for verified suppliers
