50% Tariffs on Steel, Aluminum and Derivatives U.S. Imports Effective June 4, 2025 (Reminder)
A reminder that Chapter 73 and 76 can now be broken out. Effective June 4, 2025, the United States will double Section 232 tariffs on steel and aluminum imports—from 25% to 50%—under a new presidential proclamation. While the U.K. will retain the 25% rate through July 9, the Commerce Secretary may later impose quotas or increase duties if the U.K. fails to meet its commitments under the U.S.-U.K. Economic Prosperity Deal. The updated guidance also introduces content-based duty assessments, new Chapter 99 HTS codes, and a revised stacking order to prioritize Section 232 enforcement over IEEPA tariffs.
