Beginning February 10, 2025, President Trump has issued multiple proclamations that direct a number of actions to broaden and increase Section 232 tariffs on imports of steel and aluminum and derivative products.
On June 3, 2025 the President issued a Proclamation increasing Section 232 tariffs on subject steel and aluminum imports to 50% for all countries except the United Kingdom, which remains at 25%. The increase is effective June 4, 2025.
In a Federal Register notice published August 19, 2025, the Bureau of Industry and Security announced that 407 new HTSUS subheadings will be added to the list of products covered by the Section 232 actions on steel and aluminum and therefore subject to 50 percent tariffs. These tariffs will be effective for products that are entered or withdrawn from warehouse for consumption on or after 12:01 a.m. EDT on Aug. 18. Read more here.
ST&R offers a three-pronged approach for avoiding, mitigating, and/or recovering these and other tariffs. For more information on which of these strategies might be most effective for your business, please contact ST&R.
Affected Products
For goods classified under Chapters 73 and 76, the 232 tariff applies only to the value of the aluminum or steel content.
Adding Additional Articles to the Scope - Tariff Inclusions Process
On May 2, 2025, BIS issued an interim final rule establishing a process for including additional derivative aluminum and steel articles within the scope of these tariffs. The first round of process yielded additional items being added to the scope on August 19, 2025 (as described in Affected Products above).
New! The second round of the process opened September 15, 2025 and will close at 11:59 pm ET on September 29, 2025.
Previous Tariffs on Steel & Aluminum: June 1, 2018 - March 12, 2025
Additional tariffs of 25 percent on imported steel, and 10 percent on imported aluminum, were imposed effective June 1, 2018, with respect to nearly all countries. The U.S. later imposed tariff-rate quotas suspending these tariffs on a set volume of steel and aluminum products imported from the European Union, Japan, and the United Kingdom and suspended the steel tariffs for Ukraine through June 1, 2025.
The tariffs were extended to certain derivatives of steel and aluminum articles as of Feb. 8, 2020, though there were exceptions for Argentina, Australia, Brazil, Canada, the EU, Japan, Korea, Mexico, and the UK for derivatives of steel and for Argentina, Australia, Canada, the EU, Mexico, and the UK for derivatives of aluminum.
Agreements that had suspended Section 232 tariffs on imports of steel and aluminum from Argentina, Australia, Brazil, Canada, the European Union, Japan, Mexico, South Korea, Ukraine, and the United Kingdom were terminated as of March 12, 2025.
All existing general approved exclusions from the tariffs were terminated as of March 12, 2025 (though granted product exclusions will remain in effect until their expiration date or until their excluded volume is imported, whichever occurs first). The process for requesting exclusions has also been terminated.
