See Adjusting Imports of Aluminum into the United States , 90 FR 9807 ( February 10, 2025 ). In Proclamation 10895, the President authorized and directed the Secretary of Commerce to publish modifications to the Harmonized Tariff Schedule of the United States (HTSUS) so that it conforms to the amendments and effective dates in the proclamation. On March 5, 2025, the Bureau of Industry and Security (BIS), U.S. Department of Commerce, published the necessary modifications to the HTSUS in Annex 1 of Implementation of Duties on Aluminum Pursuant to Proclamation 10895 Adjusting Imports of Aluminum into the United States , 90 FR 11251 (March 5, 2025). On April 4, 2025, BIS published the notice in the Federal Register , Implementation of Duties on Aluminum Derivatives Beer and Empty Aluminum Cans Pursuant to Proclamation 10895 Adjusting Imports of Aluminum into the United States , revising Annex 1 to add aluminum derivative products subject to the 25 percent ad valorem tariffs on imports from all countries effective on or after 12:01 a.m. eastern daylight time on April 4, 2025.

These duties are to be applied on the entire value of the imported good.

For such situations for aluminum derivative HTSUS classifications, where the aluminum country of smelt and cast is required, report “Y” for the secondary country of smelt, and report the country reported as the country of origin of the non-aluminum article as the secondary country of smelt code, and as the country of cast. For all other fields, continue to follow the CATAIR including reporting on one entry summary line for non-Section 232 entries.
