In 1994, the North American Free Trade Agreement (NAFTA) was passed by the Federal Government. The agreement allows significant benefits for importers and exporters in the U.S., Canada and Mexico. This form must be completed by U.S. exporters and must be in the possession of the Canadian or Mexican importer at the time of Declaration to either Revenue Canada (Canadian Customs) or the Secretaria de Hacienda y Credito Publico ( Mexican Customs). Failure to complete this form completely and legibly may lead to the denial of the claim for NAFTA benefits.
