NOTE: U.S. state surface trade value equals imports to the U.S. destination state, plus exports from the U.S. state of origin. The destination state reflects the state of the importer of record, which may not always represent the final physical destination of shipments. The U.S. state of origin typically reflects the state where the goods were grown, manufactured, or otherwise produced. In some instances, it may not reflect the actual state of physical origin. Shipments for Hawaii are intermodal and are included in this dataset because a portion of the shipment moves by a land mode from either its origin or final destination.
