Trump announces Mesabi's $15 billion Iowa plant as largest U.S. steel mill
President Trump said Monday that Minnesota-based Mesabi Metallics will build a roughly $15 billion steel plant in Iowa that the White House calls the largest in U.S. history, aiming to start production around 2030 with about 1,750 permanent jobs. Ore would come from the company's new $2.5 billion Minnesota Iron Range mine; exact Iowa siting is not yet firm.

What happened
President Donald Trump announced Monday that Minnesota-based Mesabi Metallics will build a roughly $15 billion steel plant in Iowa that the White House describes as the largest in U.S. history, pairing a new Iron Range mine with an integrated mill aimed at domestic, defense-grade steel.
What was announced: Speaking in the Oval Office with Mesabi Metallics CEO Joe Broking, Chairman Rewant Ruia, Commerce Secretary Howard Lutnick, Export-Import Bank Chairman John Jovanovic, and Iowa Republicans, Trump said the company would build "the largest steel plant in American history" in Iowa. White House figures shared with CNBC put first-phase output near 7.5 million tons of steel a year, with construction supporting up to about 6,000 jobs, then a ramp toward about 10 million tons annually and roughly 1,750 permanent jobs. Production is targeted for around 2030. Lutnick called the plan a "done deal" in the Oval Office, CNBC reported. Mesabi told CNBC the project would deliver "100% American steel: mined, melted and poured in Minnesota and Iowa."
The ore supply chain: Iron ore would come from Mesabi's new roughly $2.5 billion mine on Minnesota's Mesabi Iron Range, which Trump called the first new U.S. iron ore mine in more than 50 years and which the White House said is coming online in the coming weeks at about 7.5 million tons of iron per year and roughly 350 jobs; AP and MPR News reported the mine near Nashwauk officially opened earlier this month and has hired more than 200 of its planned 350 workers. NBC reported the Export-Import Bank plans up to $10 billion in financing for Mesabi's expansion. Mesabi has not named a city for the Iowa mill; Energy Secretary Chris Wright said it would be in southeast Iowa, CBS News reported. Des Moines Register reporting cited by CBS said Iowa lawmakers may be asked to reconvene on tax breaks for the project.
Why it matters
The White House is casting the mill as proof that 50% steel tariffs and reshoring pressure are unlocking mega-scale domestic capacity — the first such "mega-steel" plant since the 1960s, officials said — and as a supply-chain play for high-grade steel usable in defense work. Industry groups wrote Trump last week urging him to keep the tariffs intact, citing tens of billions in announced steel investment. Critics of the tariff regime argue it has helped push U.S. steel prices to multi-year highs. Politically, the Iowa spotlight lands less than 40 days before midterms in a state where Republicans face competitive statewide races.
What’s next
Watch for a specific Iowa site, any special Iowa legislative session on incentives, Export-Import Bank financing documents, and Mesabi updates on Minnesota mine ramp and Iowa groundbreaking timing.
More context
Caveats: Exact Iowa siting, final permits, tax incentives, and financing close are not yet locked in public detail. Capacity and job counts are White House and company projections years ahead of first pour. CNBC noted that complex industrial builds can shrink or slip — citing past over-promised factory announcements — and that Mesabi's Minnesota project itself spent roughly two decades in development after earlier bankruptcy setbacks under a prior Essar entity. Tariff policy and midterm politics will shape how markets price the announcement.

Editorial sourcing notes
Announcement facts and job/capacity figures follow CBS News, CNBC, and NBC News reporting from the Sep 28, 2026 Oval Office event and White House briefings. Capacity: White House/CNBC cite first-phase ~7.5 million tons per year and eventual ramp to ~10 million tons; CBS summarized ~7.5 million or more once running in 2030. Permanent jobs ~1,750 (White House); construction jobs up to ~6,000 in phase one (CNBC/White House). Exact Iowa site not announced by Mesabi; Energy Secretary Chris Wright said southeast Iowa (CBS). Export-Import Bank financing of up to $10 billion for Mesabi expansion was reported by NBC citing an agency release — that figure appears tied to the company's broader Minnesota/Iowa buildout, not solely the Iowa mill. Long-term megaprojects can slip or shrink; CNBC noted past over-promised factory announcements. Refresh ~1:12 p.m. PT: Nashwauk mine opening earlier in September and 200-plus of 350 planned hires follow AP via MPR News, Sep 28, 2026; AP also located the mill in eastern Iowa, and no specific site had been named at publish.
