U.S. state: For U.S. exports to Mexico, the U.S. state is based on the state of origin as reported on official U.S. trade documents, which typically refer to the state of origin where the goods were grown, manufactured, or otherwise produced. For U.S. imports from Mexico, the U.S. state of destination reflects the state of the importer of record.This state may not always represent the ultimate physical destination of shipments.
Mexican state: For U.S. exports to Mexico, the Mexican state of destination is the state where the ultimate consignee is located, and may not always be the state of final destination. For U.S. imports from Mexico, it is not possible to obtain the Mexican state of origin due to the existing filing requirements of trade documentation.
