Claiming Preferential Treatment

A claim for preferential treatment is usually made at the time of importation on the customs document used by the importing country. The Agreement allows NAFTA claims up to one year from the date of importation. The procedures for presenting a NAFTA claim are different in Canada, Mexico, and the United States.

Generally, NAFTA claims are made at the time of importation. However, NAFTA allows for a NAFTA claim to be made by the importer within one year from the date of importation.


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.
