U.S. Steel plans to restart the Gary Tin Mill at its Gary Works facility, aiming to increase domestic tin mill production and strengthen supply availability for US customers.
The company said the restart will depend on sustained customer demand for long-term domestic supply and favourable market conditions ensuring fair competition. The move is intended to enhance access to US-made tin mill products and support domestic manufacturing and supply chains.
U.S. Steel recently filed antidumping and countervailing duty petitions against imports of tin mill products from China, Taiwan and Turkey, citing concerns over unfair trade practices.
The restart is expected in early 2027, subject to maintenance completion, material procurement and workforce readiness. The company estimates restart-related costs at USD 15-20 mln.
Founded in 1901, U.S. Steel operates across the U.S. and Central Europe. Nippon Steel, Japan’s largest steelmaker, completed its USD 14.9 bln acquisition of the company in June 2025.
