How are ports defined in the North American Transborder Freight Dataset, and which agency is responsible for maintaining this information?
The field “DEPE” represents the U.S. Customs and Border Protection district and port of entry or exit for U.S. international trade. For U.S. imports, and due to current filing procedures, the Customs port represents where the entry documentation was filed with Customs and the duties paid. This may not always be where the goods physically entered the United States. For U.S. exports, the district and port of export field identifies the U.S. Customs and Border Protection port where the shipment is cleared for export. It is supposed to represent the last U.S. Customs and Border Protection port cleared. The U.S. Census Bureau is responsible for maintaining the list of Customs districts/ports, codes and descriptions. This is known as the Schedule D.
