Trump Unveils $15 Billion Mesabi Metallics Steel Mill in Iowa, Touting Tariffs as the Reason

President Trump announced Monday in the Oval Office that Mesabi Metallics plans to build a roughly $15 billion steel mill in eastern Iowa, joined by Commerce Secretary Howard Lutnick, Energy Secretary Chris Wright, Export-Import Bank Chairman John Jovanovic, and Mesabi executives Joe Broking and Rewant Ruia. The plant is slated to begin production in 2030, starting at 7.5 million tons of steel annually before scaling to 10 million tons, and the White House is calling it the largest steel plant ever built in the United States. It's expected to create about 1,750 permanent jobs and 5,000 to 6,000 construction jobs, with the Export-Import Bank set to provide up to $10 billion in financing.

Trump directly credited his tariff policy for the investment, noting he imposed a 50% tariff on imported steel and aluminum after doubling it from 25% earlier in his term. The Supreme Court struck down several of Trump's other tariffs this year but left the steel and aluminum duties in place. The project is also tied to Mesabi's Minnesota iron ore mine, the state's first new iron ore mine in more than 50 years, which the company says will feed the Iowa facility directly. The announcement comes weeks before the midterm elections, as Republicans look to shore up support in a state where farmers and manufacturers have faced fallout from Trump's broader trade fights.

What supporters say:

  • Commerce Secretary Lutnick said the project shows the administration's steel tariffs are "at work," driving investment back to domestic producers.

  • Trump said the steel industry is "roaring back to life" because companies would rather build in the U.S. than pay the tariff on imports.

  • Backers point to the plant's ability to supply defense-grade steel, including material used in Navy ships, as a national security benefit.

What critics say:

  • Economists note that steel tariffs raise input costs for manufacturers who buy steel, potentially offsetting job gains in other industries.

  • Mesabi's earlier $2.5 billion Minnesota mine project has so far produced only 200 of an anticipated 350 jobs, raising questions about whether the Iowa numbers will materialize on schedule.

  • Farmers and other trade-exposed industries have already absorbed costs from Trump's broader trade wars, complicating the political payoff Republicans are counting on before November.
