A presidential proclamation doubles "Section 232" duties on steel, aluminium and their derivatives from 25% to 50% as of 4 June 2025, after country exemptions were scrapped in February.

What changes

10 February 2025: Proclamations 10895 and 10896 extend 25% duties to all countries.
4 June 2025: rate raised to 50% on steel, aluminium and derivative products.
Derivatives cover many metal parts and subassemblies.
Derivatives stay outside the 15% ceiling later negotiated with the EU.

### Background In a proclamation issued in early June 2025, the US President raised "Section 232" tariffs on **steel**, **aluminium** and their **derivative products** from 25% to **50%**, effective **4 June 2025** at 12:01 a.m. Eastern time. ### Timeline - **10 February 2025**: Proclamations 10895 (aluminium) and 10896 (steel); the 25% duty now applies to all countries with no exemptions, from 12 March 2025. - **4 June 2025**: increase to 50%. - **21 August 2025**: EU–US joint statement; 15% ceiling for most EU exports, but steel, aluminium and their derivatives still face up to 50%. ### Why it matters "Derivatives" cover many components and subassemblies containing steel or aluminium: machinery, mechanical parts, electrical equipment. For European exporters, this means recomputing cost prices, documenting the metal content of products and sometimes relocating final assembly. Engineering offices are called on for material trade-offs and redesigns. ### Key takeaway Doubling metal tariffs makes the bill of materials and the origin of materials a strategic topic for any manufacturer selling to the United States.
