Drawback is a refund, reduction or waiver in whole or in part of Customs duties collected upon importation of an article or materials which are subsequently exported. Under NAFTA, this refunded amount is the lesser of the amount of duties paid upon importation into the NAFTA territory and the total amount paid on the finished good is the NAFTA country to which it is exported. Drawback became effective for trade between Canada and the United States on January 1, 1996, and for trade between Mexico, the United States and Canada, this program became effective on January 1, 2001.
