Historical reciprocal tariff for MM-origin goods

A “historical reciprocal tariff for MM-origin goods” is a U.S. trade measure recorded under IEEPA, the International Emergency Economic Powers Act. “MM-origin” is the country-of-origin code used in the trade data; confirm which country that code represents in the applicable source. “Reciprocal tariff” generally refers to an additional import duty intended to address differences in trade treatment between countries, while “historical” indicates that the measure may relate to a past period or may no longer be active.

This type of measure typically affects goods whose country of origin is the specified country, not merely goods shipped from there. It can change the total landed cost and may require a separate tariff line, special reporting instruction, or additional duty calculation. The importer remains responsible for using the correct classification, origin determination, and entry information, subject to review by Customs and Border Protection and, when needed, a customs broker or trade adviser.

What to check

• Confirm whether the measure is currently active or is retained only as historical data; do not assume a listed measure applies to a new entry.
• Verify the product’s country of origin under U.S. origin rules, rather than relying only on the shipping country or supplier location.
• Identify the correct Harmonized Tariff Schedule classification and check whether the measure applies to that tariff provision or product scope.
• Check the official entry instructions for any additional duty line, reporting code, exclusions, exceptions, or interaction with other trade measures.
• Have a customs broker or trade counsel review uncertain origin, classification, scope, or IEEPA applicability before filing the entry.
