Historical reciprocal tariff for AO-origin goods

A historical reciprocal tariff is an additional U.S. import measure that was applied to certain goods based on the country of origin’s treatment of U.S. goods. “Reciprocal” generally means the measure was intended to respond to differences in tariffs or other trade barriers. “IEEPA” refers to the International Emergency Economic Powers Act, a U.S. law that can provide authority for certain import-related economic measures. “AO-origin” identifies the origin category used by the source data; confirm exactly which country or territory that code represents.

This type of measure typically affects U.S. importers whose goods are legally determined to originate in the covered country or territory, even if the goods were shipped through another location. Because the measure is labeled historical, it may apply only to past entries or may have been changed, suspended, replaced, or ended. It matters because it can create an additional duty separate from the ordinary HTSUS tariff rate, and the importer generally remains responsible for correct classification, origin, entry data, and payment or reconciliation.

What to check

• Confirm in the official measure source whether the measure is historical only, and identify its applicable entry dates and current status.
• Verify what “AO” means in the source and document the product’s customs country of origin; do not rely only on the shipping or export location.
• Check the measure’s HTSUS provisions, product scope, exclusions, and any required reporting instructions against the product’s tariff classification.
• Determine whether the reciprocal duty is an additional duty on top of ordinary customs duties and whether other trade measures may also apply.
• Ask a customs broker or trade adviser to review difficult origin, classification, exclusions, or post-entry correction questions.
