According to a statement by U.S. Customs and Border Protection (CBP), CBP is preparing to test several new use cases for blockchain in the trade compliance environment, including verifying the origin of certain raw material imports, verifying the composition of liquids imported via pipeline under free trade agreements and a potential joint test with the U.S. Postal Service. Following these tests, CBP will present the results of the use cases to the Commercial Customs Operations Advisory Committee (COAC), after which the agency hopes the private sector provides their thoughts.
