The document discusses foreign-trade zones (FTZs) and how they promote U.S. investment, manufacturing, and exports. FTZs allow companies to import goods without customs duties, provide duty elimination on exports and scrap, and offer duty reduction for manufacturing. This can result in significant cost savings for companies. Hypothetical examples show over $700,000 in potential first year savings for a company using an FTZ, primarily from duty deferral, duty elimination on exports/scrap, inverted tariff benefits, and reduced administrative costs. FTZs also offer benefits like improved inventory control and compliance.
