CBP Guidance for Section 232 Aluminum Import Instructions to Report Unknown for Country of Smelt and Cast
Effective June 28, 2025, CBP will require importers of derivative aluminum subject to Section 232 to report “unknown” for smelt or cast origin when that information is not available. Entries marked “unknown” must declare HTS 9903.85.67 or 9903.85.68 and will incur the 200% tariff rate applied to Russian aluminum. CBP’s updated guidance outlines mandatory reporting codes, ISO requirements, and new ACE system error messages tied to smelt and cast data.
