(USA) Merchandise admitted to a U. S. Foreign Trade Zone may be given a special status which affects what may done with it. For example: when entered into the U. S. Customs territory it may be dutiable at rates and values applicable at that time; or it may be given a status which fixes the applicable rates and values at those in effect at the time when it was admitted to the zone; or it may have a status which denies entry to the U.S.A. altogether.
