June 2025 Changes Require Clear Smelt and Cast Declarations or Face Steep Penalties

Starting June 4 and June 28, 2025, U.S. Customs and Border Protection (CBP) is enforcing new rules for importing aluminum and derivative aluminum products under Section 232.

Key changes include a shift in how duties are calculated — now based solely on the aluminum content of the product — and new duty rates ranging from 25% to 200% depending on origin. Notably, products from Russia or with unknown origin details will face a steep 200% duty, while those from the United Kingdom remain at 25%.

From June 28 onward, all importers must report the country of smelt and cast for aluminum content. If either is unknown, the shipment will automatically incur the 200% penalty duty.

The CBP’s latest guidance outlines various Harmonized Tariff Schedule (HTSUS) codes under Chapter 99 to reflect these new classifications and duty structures. Importers must ensure accurate classification, clear supplier documentation, and proper entry declarations to remain compliant.

The updated rules also eliminate the possibility of drawback (duty refunds) for these Section 232 duties, tightening the compliance landscape. Importers using recycled or U.S.-origin aluminum must maintain documentation to prove processing origins.

Failure to comply with the reporting and classification requirements could trigger enforcement actions by CBP. Companies are urged to coordinate closely with suppliers and customs brokers to avoid costly errors.
