Gary Tin Mill Restart Signals Shift in Steel Supply Chains
US Steel has announced it is restarting its Gary Tin Mill operations, strengthening American supply of the metal.
This comes at a time of strengthened demand for domestic supply chains – particularly as US President Donald Trump aims for a strong US production line.
The reopening of the mill and its operations will create new jobs and support a stronger supply chain across manufacturing.
Strengthening a US supply chain
US Steel was founded in 1901 and operates to deliver profitable and sustainable steel solutions, with a focus on employee safety.
The company serves the construction, automotive, appliance, energy and packaging industries. It has competitive iron ore production capabilities and electric arc furnaces, working towards the creation of stronger, lighter and more environmentally responsible steels.
Its operations span the US and Central Europe, with production intended to help build electric vehicles, generators and transformers.
US Steel has announced plans to restart its Gary Tin Mill at its Gary Works facility. The aim is to increase domestic tin mill production, while ensuring customers can gain access to American-made supply.
The facility is a major steel mill in Indiana and is one of the largest integrated mills in North America. It has an integrated mill, as well as steelmaking and finishing facilities.
Production has fallen since the mid-20th century, resulting in a decline in staffing levels, but US Steel is confident in its decision to reopen the tin mill. The planned restart requires long-term customer interest in a domestic tin mill supply, but recent US determinism for an American supply chain has the company certain that this is the right move.
“Customers are increasingly focused on securing dependable domestic supply they can count on over the long term,” says US Steel President and Chief Executive Officer, David B. Burritt.
“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.”
Reducing imports
US Steel believes that it can meet demands with increased production amid the right market conditions. The restarting of operations is intended to offer reliable, American made tin mill products – which have been mined, melted and made in America – as part of an increasingly domestic supply chain.
Under President Trump's leadership, a strong US domestic supply chain is at the forefront of many manufacturers and business leaders – particularly as an incentive to avoid tariff prices. As such, more operations are moving towards the US and previously closed facilities are opening their doors once more.
On April 9, US Steel filed antidumping duty (AD) petitions against imports of tin and chromium coated sheet steel from Taiwan, China and Turkey. As well as this, it filed a countervailing duty (CVD) petition against subsidised imports of tin mill products from China.
US Steel alleges these countries are selling their products at artificially low prices in order to become main sourcing partners of steel, which it says risks putting American companies out of business. Its aim is to reduce foreign products from being a major source in the supply chain.
Operations are expected to begin in early 2027, following maintenance activities, procurement of materials and workforce readiness. The company is anticipating restart costs of US$15-20m, which will primarily focus on operational readiness, equipment inspections, maintenance and materials purchasing.
US Steel also anticipates the direct supporting of 225 jobs at Gary Works. It is dedicated to ensuring the Gary Tin Mill can operate reliably and safely, in alignment with the annual contracting cycle for tin mill products.
The products produced at the mill will be used in a range of items including food and beverage packaging and oil filtration goods.
