President Donald Trump on September 28 announced that Mesabi Metallics, a Minnesota-based steelmaker backed by India’s Essar Group, will invest $15 billion to build what would be the largest steel mill in U.S. history in Iowa. The project promises 1,750 permanent jobs and 10 million tons of annual capacity, with production slated to begin in 2030. The White House put the economic impact at $95 billion across construction and the first decade of operations, though federal and state funding details remain undisclosed.
The tariff backdrop
The announcement arrives two years after the administration doubled the Section 232 tariff on metal imports to 50 percent and subsequently tightened exemptions. Those measures helped push the United States past Japan as a crude steel producer last year for the first time since 1999. Trump framed the Mesabi project as direct evidence that producers are relocating to avoid the duties. “Everyone’s building their plant here because they don’t want to pay tariffs,” he said. Manufacturers, meanwhile, continue to cite higher raw material costs and consumer prices as the trade-off.
Private money, public questions
Commerce Secretary Howard Lutnick described the deal as done and funded privately. Trump said the public sector contribution amounts to “very little.” Whether Iowa or Minnesota offered incentives remains unclear. Mesabi has also committed an additional $3 billion to finish its iron ore mine in Nashwauk, Minnesota, where 1,500 construction workers and 200 employees are already producing what the company calls Patriot Pellets. The Iowa mill would run on electric arc furnaces fed by that mine’s direct-reduced iron and recycled scrap.
A pattern of pushback
The Iowa project joins a roster of administration-backed metals investments that have drawn local opposition. Hyundai Steel’s $5.8 billion Louisiana mill broke ground on September 4 after environmental and nuisance concerns delayed it. A $4 billion aluminum smelter in Oklahoma led by Emirates Global Aluminum and Century Aluminum has been pushed to April 2027 after Inola’s town council extended a pause; the developers responded with an economic impact study. Trump called the Oklahoma plant “unbelievable” and one of his favorite projects.
