Historical reciprocal tariff for BN-origin goods

A “historical reciprocal tariff for BN-origin goods” is a trade measure that applied, during a specified past period, to goods whose country of origin was Brunei (often identified by the country code “BN”). “Reciprocal” generally means the measure was intended to respond to trade treatment affecting U.S. goods, while “IEEPA” refers to the International Emergency Economic Powers Act, the legal authority used for certain trade-related actions. “Historical” indicates that the measure is tied to past entries or past periods, not necessarily goods entering today.

For an importer, the measure may have operated as an additional duty or other import requirement layered onto the normal tariff classification under the Harmonized Tariff Schedule of the United States (HTSUS). The key issues are the product’s country of origin, the date and type of customs entry, the applicable HTSUS provisions, and whether an exclusion, exemption, or later correction applied. Confirming treatment can require reviewing official customs instructions or obtaining customs-broker guidance.

What to check

• Verify that “BN” means the product’s customs country of origin is Brunei—not merely the shipping country, seller location, or transit country.
• Check the entry date and the measure’s stated effective period to determine whether a historical rule could apply.
• Review the complete HTSUS classification, including any additional tariff provisions, product descriptions, exclusions, and reporting instructions.
• Confirm whether the product qualified for an exclusion, exemption, preference program, or correction procedure under the official measure information.
• Keep supporting records for origin, classification, valuation, and entry filings, and ask a customs broker to review uncertain or retroactive-duty issues.
