Accepted Answer

Updated as of 20 August 2026.

Steel, aluminium, and copper.
On 2 April 2026, the US announced adjustments to its Section 232 tariffs on metals. Key adjustments include a new tiered structure, where a tariff rate is applied depending on the metal product (see table below). The tariff rate is applied to a good’s full product value, regardless of metal content. Previously, the tariff rate was applied to the value of a good’s metal content. For the full list of goods, refer to the White House Proclamation “Strengthening Actions Taken to Adjust Imports of Aluminum, Steel, and Copper into the United States”.

Annex	Coverage	Section 232 Tariff Rate
I-A	Core metals and close derivatives (Articles made entirely or almost entirely of aluminium, steel, or copper and are not casted and smelted in the US)	50%
I-B	Downstream manufactured articles (Derivative articles of steel or aluminium and copper articles and not casted and smelted in the US)	25%
III	Further select derivative products that are not casted and smelted in the US (until 31 Dec 2027)	15%, or the MFN rate, whichever is higher. Note: From 01 Jan 2028, the 15% tariff rate will increase to 25% tariff under ANNEX I-B list, and is stacked with the applicable MFN rate.
-	Product is made from steel, aluminium or copper inputs that are casted and smelted in the US (Applies to products in Annex I-A, I-B, and III)	10%, or the MFN rate, whichever is higher.
II	Products with >15% metal content	10%
II	Products with <15% metal content, and not listed in Annex I (A and B) and III	0%
