Second Tier Sourcing is a procurement policy that is used by various Fortune 500 corporations. This is a practice of rewarding suppliers for attempting to achieve minority-owned business spending goals of their customer(s).

The program was created by the Chrysler Corporation in 1993 and now extends throughout the Fortune 500. In 2005, Toyota set a goal of 10% for their suppliers and holds an annual matchmaking event to help their suppliers achieve those goals.
