Customer requests for assurances of regulatory compliance for food-contact materials are quite common in the United States. Three major forms of customer assurances are: a guaranty letter issued under Section 303(c)(2) of the Food, Drug, and Cosmetic Act (FD&C Act); a letter from a supplier to its customer advising that the material in question is in compliance with the FD&C Act and all applicable FDA food additive regulations; or confirmation from a third party, such as legal counsel.
