Tata Steel UK has received an exemption from US steel tariff rules, allowing steel processed at its Port Talbot plant in Wales to be exported to the US under the reduced tariff rate applied to UK shipments.

The exemption means that products manufactured at the Port Talbot facility can be treated as UK-origin steel, even though the raw materials may come from outside Britain. 

Under current US trade measures, most steel imports face a 50% tariff, while UK shipments are subject to a reduced 25% rate, provided they meet strict "smelting and casting" rules requiring the steel to be entirely British.
