Guidelines and General Information

1. There are two CUSMA tariff treatments: the United States Tariff (UST) and the Mexico Tariff (MXT).

2. Importers will use tariff treatment 10 for UST and 11 for MXT on accounting documents.

Tariff Treatment Determination

3. In order to determine which preferential tariff treatment should be applied to eligible goods imported from a CUSMA country, two levels of origin determinations must be made. First, the goods must be originating in accordance with the CUSMA Rules of Origin Regulations. Once it is established that the goods originate, a determination must also be made as to whether UST or MXT is applicable as provided for in the CUSMA Tariff Preference Regulations.

Textile and Apparel Goods

4. For further information on how to obtain the benefits of the preferential rates of customs duty accorded under the CUSMA using the Tariff Preference Level (TPL) mechanism, refer to Memorandum D11-4-22, Tariff Preference Levels and the Imports of Certain Textile and Apparel Goods from Mexico or the United States Customs Duty Remission Order.
