Historical reciprocal tariff for KH-origin goods

A “historical reciprocal tariff for KH-origin goods” refers to a past U.S. trade measure associated with goods whose country of origin is identified as KH. “KH” is the country-code designation used for Cambodia. “Reciprocal tariff” generally describes an additional import charge designed to respond to another country’s treatment of U.S. goods or to address a trade imbalance or related policy concern. “IEEPA” means the International Emergency Economic Powers Act, a U.S. law that can provide authority for certain trade-related actions during a declared national emergency.

For an importer, this type of measure matters because it may be an extra duty layered on top of the product’s ordinary tariff classification, such as its HTSUS subheading. The word “historical” signals that the measure concerns a past period or prior rule; it does not by itself establish that the charge applies to a current entry. Applicability usually depends on the goods’ legal country of origin, entry or withdrawal date, tariff classification, exclusions, and any later amendments or termination. Confirming the result may require a customs broker or trade counsel.

What to check

• Verify that the goods’ country of origin is KH under U.S. origin rules, rather than relying only on the shipping country or seller location.
• Check the relevant entry or withdrawal date and confirm whether the historical measure was in force for that transaction.
• Review the complete HTSUS classification and any additional tariff provisions, exclusions, or product-specific exceptions that may apply.
• Determine whether the measure is an additional duty layered onto ordinary customs duties, and report it using the required tariff provisions and entry data.
• Use current CBP guidance, official tariff notices, and the applicable HTSUS edition; ask a customs broker or trade counsel to resolve uncertainty.
