U.S. Adjusts Section 232 Metal Tariffs (Copper Smelt and Cast Country Detail Error Code Update)
CBP will begin rejecting ACE entry summaries missing required copper primary country of smelt and country of cast information on September 14, 2026. The change applies to certain copper articles under four HTSUS classifications. ACE will issue a fatal F794 error when the required Type 12 record is not submitted. Importers may report “OTH” when required country information is unknown.
