In the past, goods originating in the United States which were exported and then returned have been allowed to enter the U.S. without payment of duties under certain circumstances. Under the Trade Facilitation and Enforcement Act of 2015 (TFTEA) and the new US-Mexico-Canada Agreement (USMCA), there have been changes to the regulatory and documentary requirements to take advantage of these benefits. The burden of proof remains on the importer, and as such, the proof is in the proverbial pudding.
