In order to claim preferential tariff treatment under the Canada-United States-Mexico Agreement (CUSMA), a certification of origin is required. The certification of origin has no prescribed format, but instead consists of a set of minimum data elements.
The certification of origin may be completed by either the exporter, producer, or importer of the goods for the purpose of certifying that a good being exported from the territory of another Party qualifies as an originating good. It may be provided on an invoice or any other document, and may be completed and submitted electronically including with an electronic or digital signature.
