Tata Steel UK has secured lower U.S. tariff treatment for steel processed at its Port Talbot plant, allowing exports to qualify for the reduced tariff rate applicable to British steel imports despite the use of imported substrate.
Under current U.S. trade measures, most steel imports are subject to a 50pct tariff, while UK-origin steel faces a lower 25pct duty. However, the lower tariff generally requires compliance with melt-and-pour rules under which the steel must be fully produced in the UK.
According to the company, steel processed at Tata Steel’s Port Talbot facility in Wales will continue to qualify as UK-origin material during the plant’s transition phase, even though the raw material is sourced overseas.
Tata Steel halted blast furnace operations at Port Talbot in 2024 as part of its transition toward electric arc furnace-based steel production, resulting in temporary reliance on imported substrate, including material from the company’s operations in the Netherlands.
The company stated that the exemption reflects the transitional status of the Port Talbot plant ahead of commissioning of the new electric arc furnace facility.
