Historical reciprocal tariff for ZM-origin goods

A “historical reciprocal tariff for ZM-origin goods” is a past U.S. trade measure associated with goods whose country of origin is represented by “ZM” and whose tariff treatment was established under the International Emergency Economic Powers Act (IEEPA). “Reciprocal” generally refers to an additional tariff intended to respond to perceived differences in trade treatment, while “historical” means the measure may apply only to an earlier period rather than to current entries.

The measure typically concerns the interaction of three elements: the product’s tariff classification under the Harmonized Tariff Schedule of the United States (HTSUS), its country of origin, and the entry or importation date. It may be collected as an additional duty on top of the ordinary duty, unless an exclusion, exception, or other rule applies. Importers should confirm the measure’s status and application with current official tariff guidance or a qualified customs broker before making an entry.

What to check

• Confirm whether the measure is still effective for the planned entry date; a historical listing is not proof that it applies to current imports.
• Verify the product’s HTSUS classification, because additional measures often identify covered tariff lines or product descriptions.
• Document the product’s country of origin under U.S. customs rules; “ZM-origin” should be checked against the actual manufacturing and substantial-transformation facts.
• Check the official measure instructions for the correct additional-duty provision, exclusions, exceptions, and any required entry-summary reporting.
• Have a customs broker or trade specialist review uncertain classification, origin, or IEEPA applicability before filing the entry.
