How do FTZs differ from other programs administered by Customs?

With FTZs, there is generally no time restraints on merchandise remaining in a zone, unlike other similar programs (bonded warehouses, drawback, and temporary importing under bond) administered by Customs. Domestic and foreign goods may be admitted to a zone without being subject to Customs' duties or certain excise taxes. Goods may be exported from a zone free of duty and tax. For more information on bonded warehouses, drawback, or temporary importation bonds contact your local US Customs Service Port Director. Information on FTZs can be obtained by contacting the Ports Authority.
