Duty Deferral
Duty deferral is interest that could be earned on money paid for duty fees. Because an FTZ will allow the duty to be deferred from the time that the item enters the compay inventory until the time that it enters the market, that money can remain within the company during this time, and can be used to earn interest or to prevent the company from having to borrow money.
