Modifications to Tariffs under Section 232 on Steel, Aluminum, and Copper

April 3, 2026

Effective Monday, April 6, 2026

President Trump has issued a new Proclamation modifying the tariffs imposed under Section 232 on Steel, Aluminum, and Copper.

The Proclamation defines the way that tariffs are assessed, ensuring that they reflect the full value of imported steel, aluminum, and copper products.

The new Section 232 tariff rates for steel, aluminum, and copper will go into effect on Monday, April 6, 2026. Details on the affected metals and their corresponding tariff rates are provided below:

Metals:

- 50% tariff on the full value of certain steel, aluminum, copper goods classified in Chapter 72, 73, 74, and 76
- 25% tariff on the full value of certain steel, aluminum and copper derivatives listed in Annex I of the proclamation (no more splitting lines based on metal content value)
- A temporary 15% tariff, inclusive of Most Favored Nation (MFN) rate-based duty, on certain metal-intensive industrial equipment and electrical grid equipment through the end of 2027
- Removal of many steel/aluminum derivative items from lists of goods subject to tariffs. The inclusion process is also ended, but additional products may be added at the administration’s discretion, listed in Annex II (pg. 29) of the proclamation
- De minimis exemption for goods outside of Chapters 72, 73, 74 and 76 if the weight of the subject metal is less than 15% of the imported article. If the article is on more than one metal list, use the aggregate weight of the listed metals.
- 0% duty on motorcycle parts in Chapters 84, 85 or 87 when imported exclusively for use in the manufacturing of motorcycles
- If an item is listed as an article or derivative of more than one metal, it will be subject to only one duty assessment for 232 steel/aluminum/copper, even if it contains more than one metal.
- For derivative products manufactured abroad with 95% or more US steel/aluminum/copper the rate is now 10% instead of 0%. For some goods it is 10% additional, others 10% inclusive of MFN.
- Goods from the U.K. that would otherwise be subject to the 50% rate are subject to a 25% tariff rate, and goods subject to the 25% rate for derivatives will be subject to a 15% rate.
- Manufacturing drawback under 19 U.S.C. 1313(a) and (b) will be allowed for goods subject to the Section 232 tariffs on steel, aluminum and copper. But that applies only to goods from a “Trade Agreement Partner,” currently the U.K., EU, Japan, South Korea, Mexico, Canada and “any trading partner with which the United States concludes a final Agreement on Reciprocal Trade.”
  To qualify, the goods must also not be subject to antidumping or countervailing duties, and the aluminum, copper or steel must be entirely smelted and cast or melted and poured in a trade agreement partner country.

This latest Presidential Proclamation is very detailed, and Deringer recommends that U.S. importers review Metals-ANNEXES-I-A-I-B-II-III-IV.pdf for the applicability of the new tariff rates.
