The Basics of Foreign Trade Zones 

In the United States, foreign trade zones (FTZs) are the domestic equivalents of international “free trade zones,” intended to encourage healthy competition with foreign businesses. These zones directly help U.S. companies who either import products or components from foreign countries by reducing, deferring, or eliminating duties and by allowing for greater supply chain efficiency.

San Antonio’s Foreign Trade Zone

As a city committed to maximizing its presence in the global economy, San Antonio is an ideal location for businesses interested in increasing their export power. With its engagement in globally-oriented economic programs and its optimal geographic location, the city provides a wide array of business opportunities, a quality enhanced by its Foreign Trade Zone designation.

Accessing Benefits

Essentially, foreign trade zones help businesses reduce production, transaction, and logistics-related costs by allowing them to defer paying customs costs on goods imported into the U.S. until those goods leave the zone for consumption. Benefits include duty deferral, duty exemption, avoiding inverted tariffs, and logistical benefits.

 FTZ Operation Types

  • Storage: Foreign and domestic merchandise may be stored within the zone for an unlimited period of time, thereby avoiding all duties and excise taxes.
  • Approved operations for admitted merchandise: Goods may be opened, examined, sampled, displayed, assembled, mixed, cleaned, labeled, or repackaged within a zone.
  • Manufacturing: products manufactured within the zone, including foreign merchandise, can face reduced duties if the tariff rate on the finished product (the product leaving the zone) is lower than the tariff applied to the initial components (the product entering the zone).
  • Disposal: Waste materials and damaged or valueless merchandise can be destroyed within the zone without encountering duties.

Benefits for Foreign Trade Zone Users:

  • Avoid payment of duties on imported goods that are later re-exported or are used in manufacturing domestic goods
  • Delay payments of duties on goods that enter the U.S. market
  • Eliminate duties on waste, scrap, and rejected/defective parts
  • Reduce or eliminate duties on quota charges for merchandise leaving the zone
  • Avoid quota restrictions until merchandise leaves the zone
  • Reduce merchandise processing fees, since zone users are allowed to file a single customs entry—and pay a single fee—per week, instead of filing and paying per entry
