U.S. Administration Adjusts Section 232 Tariffs for Steel, Aluminum, and Copper

On April 2, President Trump signed a proclamation modifying Section 232 tariffs on steel, aluminum, and copper. It also sets updated rules for calculating Section 232 metals tariffs, detailing how duties will be assessed under the revised framework.

The new Section 232 tariff rates will be in effect at 12:01am ET on April 6^th, 2026.

The Proclamation introduces updated rules for calculating Section 232 metals tariffs:

• Articles made entirely or almost entirely of aluminum, steel, or copper will pay a flat 50% on their full value — for example, steel coils and aluminum sheet.

• Derivative articles substantially made of steel, aluminum, or copper will pay a flat 25% on their full value.

• Certain metal-intensive industrial equipment and electrical grid equipment will pay 15% through 2027, to accelerate the massive industrial base buildout currently underway across the United States.

• Products made abroad but entirely with American steel, aluminum, and copper will be subject to lower tariffs of 10%.

• Products made of 15% or less steel, aluminum, or copper will no longer be subject to Section 232 metals tariffs.

The Annexes also identify several articles that are being removed from the scope of Section 232 steel and aluminum derivative tariffs.

We’ll be reaching out directly with updated documentation requirements. Please note that the new documentation versions will take effect on Monday, April 6, 2026.

Using the updated forms will help ensure your shipments continue to move smoothly; older versions may result in delays or holds at the border.
