United States Steel Corporation (US Steel) has announced plans to restart the idled Gary Tin Mill at its Gary Works facility in Indiana, aiming to boost domestic production of tin mill products and strengthen American-made supply chains. The move is contingent on sustained customer demand for long-term domestic supply and the company’s confidence that US production can meet that demand under fair market conditions.
This announcement comes as US Steel continues broader modernization efforts at Gary Works, supported by its partnership with Japanese steelmaker Nippon Steel, as SteelOrbis previously reported. The collaboration includes major capital investments across the facility, such as the previously approved $350 million reline of blast furnace No. 14 and upgrades to the hot strip mill, as part of Nippon Steel’s commitment to invest approximately $11 billion in US Steel operations by the end of 2028.
The steelmaker said the restart, expected in early 2027, will increase access to reliable, “mined, melted, and made in America” tin mill products used in critical applications such as food and beverage packaging, aerosol containers, oil filtration, and other essential markets that support US manufacturing and agriculture. The timing aligns with the annual contracting cycle for tin mill products. The company plans a deliberate, phased approach to ensure safe and reliable operations following completion of necessary maintenance and readiness activities.
Restart-related costs are estimated at $15-20 million, primarily for equipment inspections, maintenance, procurement of materials, and workforce preparation. The project is expected to support approximately 225 jobs at Gary Works once operational.
The Gary Tin Mill restart underscores US Steel’s focus on maintaining integrated steelmaking capabilities while addressing import pressures and meeting demand for high-value steel products in key domestic sectors.
US Steel president and CEO David B. Burritt said, “Customers are increasingly focused on securing dependable domestic supply they can count on over the long term. Restarting the Gary Tin Mill positions us to serve that demand, support domestic manufacturing, and strengthen critical US supply chains - including those that help support American farmers and food producers - provided trade is fair and enforced.”
Its noteworthy that the US International Trade Commission initiated antidumping duty investigation into imports of tin mill products from China, Taiwan and Turkey, and countervailing duty investigation into imports of the given products from China, following a petition filed by US Steel and the United Steelworkers, as SteelOrbis previously reported.
