China-owned British Steel said it could close its two blast furnaces as soon as June with the potential loss of up to 2,700 jobs, as U.S. tariffs and environmental costs threaten to damage its already struggling operations.

British Steel said Thursday that it is planning to close its two blast furnaces and steelmaking operations in the northern England town of Scunthorpe, after its Chinese owner Jingye failed to agree a rescue package with the U.

British Steel is launching a consultation that could see the closure of its two blast furnaces at Scunthorpe, putting up to 2,700 jobs at risk out of a workforce of 3,500. The company said the blast furnaces were "no longer financially sustainable" due to tough market conditions, the imposition of tariffs and higher environmental costs.
