CBP Form 434, North American Free Trade Agreement (NAFTA) Certificate of Origin - also known as the CBP certificate of origin or the NAFTA CBP Form 434 - is a form used by the United States, Canada, and Mexico with the intention to certify that the goods qualify for the preferential tariff treatment agreed by NAFTA. The certificate of origin sums up the claim that the goods qualify as originating, which means they should receive preferential tariff treatment. The Customs and Border Protection (CBP) requires the exporter to complete this form. A manufacturer or a producer may also complete it in a NAFTA territory in order to use it as a basis for an Exporter's Certificate of Origin. To request NAFTA preference, the importer has to possess a certificate of origin when the claim is made.
The latest version of the form was released by the CBP in November 2016 with all previous editions obsolete. A CBP Form 434 fillable version is available for download and digital filing below.
The CBP Form 434A - also known as the CBP Form 434 continuation sheet - is a related form containing similar information which did not fit in the first form. It describes the goods, identifies their Harmonised System (H.S.) tariff classification numbers, states the preference criterion, indicates the producer, describes the net cost, and states the country of origin.
