Background

On April 2, the President issued Proclamation 11021, “Strengthening Actions Taken to Adjust Imports of Aluminum, Steel, and Copper into the United States,” under Section 232 of the Trade Expansion Act of 1962, as amended (19 U.S.C. 1862). This proclamation imposes 10-50% additional duties on the full customs value of certain imports of steel, aluminum, copper articles (metal articles) and their derivatives from all countries, effective April 6, 2026. See 91 FR 18201 and CSMS 68253075.

On April 29, the Commerce Secretary published “Notice of Technical Corrections to the Harmonized Tariff Schedule of the United States for Duties Imposed by Presidential Proclamation 11021.” See 91 FR 23056.

New HTSUS classification 9903.82.01 established by this Notice is already effective in ACE. The ACE functionality for the acceptance of goods with a melt and pour country of the Netherlands under Headings 9903.82.04 and 9903.82.05 will be available on May 7.
