ATA Carnet is an international customs document that allows for the temporary importation of goods into a country. Because it is accepted in both Canada and the United States, it can act as a both a Canadian and U.S. Shipment Type for goods to clear through both CBSA and CBP.

Carnets are typically used for commercial samples, professional equipment and goods for use at exhibitions, and fairs. To qualify for a Carnet the goods must not be consumable items such as agricultural products. Goods may be imported under Carnet for a period of up to one year depending on the validity period specified.

The Carnet should be obtained by the party temporarily importing the goods. The importer should inform the carrier that this is the shipment type being used, and provide them with the Carnet document, as the driver will need to present this at the border.
