Foreign Trade Zone #80-10

Port San Antonio’s entire 1,900 acre site is covered by a General Purpose Foreign-Trade Zone (#80-10) designation, allowing our customers the option of activation at any of the Port’s sites or existing buildings.

Foreign-Trade Zones are considered outside the territory of the U.S. for customs purposes. Therefore, goods admitted in a designated Foreign-Trade Zone are not subject to formal U.S. Customs entries or payment of duties while in the zone.
