Trump tells U.S. steelworkers he’s going to double tariffs on foreign steel to 50%

WEST MIFFLIN, Pa. — President Trump told Pennsylvania steelworkers he’s doubling the tariff on steel imports to 50% to protect their industry, a dramatic increase that could further push up prices for a metal used to make housing, autos and other goods.

In a post later on his Truth Social platform, he added that aluminum tariffs would also be doubled to 50%. He said both tariff hikes would go into effect Wednesday.

Trump spoke Friday at U.S. Steel’s Mon Valley Works–Irvin Plant in suburban Pittsburgh, where he also discussed a details-to-come deal under which Japan’s Nippon Steel will invest in the iconic American steelmaker.

Though Trump initially vowed to block the Japanese steelmaker’s bid to buy Pittsburgh-based U.S. Steel, he reversed course and announced an agreement last week for “partial ownership” by Nippon.

It’s unclear, though, if the deal his administration helped broker has been finalized or how ownership would be structured. Nippon Steel has never said it is backing off its bid to outright buy and control U.S. Steel as a wholly owned subsidiary, even as it increased the amount of money it promised to invest in U.S. Steel plants and gave guarantees that it wouldn’t lay off workers or close plants as it sought federal approval of the acquisition.

“We’re here today to celebrate a blockbuster agreement that will ensure this storied American company stays an American company,” Trump said as he opened an event at one of U.S. Steel’s warehouses. “You’re going to stay an American company, you know that, right?”

As for the tariffs, Trump said doubling the levies on imported steel “will even further secure the steel industry in the U.S.” But such a dramatic increase could push prices even higher.

Steel prices have climbed 16% since Trump became president in mid-January, according to the government’s Producer Price Index.

As of March 2025, steel costs $984 a metric ton in the United States, significantly more than the price in Europe ($690) or China ($392), according to the U.S. Commerce Department. The United States produced about three times more steel than it imported last year, with Canada, Brazil, Mexico and South Korea being the largest sources of steel imports.

Analysts have credited tariffs going back to Trump’s first term with helping strengthen the domestic steel industry, something that Nippon Steel wanted to capitalize on in its offer to buy U.S. Steel.

The United Steelworkers union remained skeptical.

Its president, David McCall, said in a statement that the union is most concerned “with the impact that this merger of U.S. Steel into a foreign competitor will have on national security, our members and the communities where we live and work.”

Trump stressed the deal would maintain American control of the storied company, which is seen as both a political symbol and an important matter for the country’s supply chain, industries like auto manufacturing and national security.

Trump, who has been eager to strike deals and announce new investments in the U.S. since retaking the White House, is also trying to satisfy voters, including blue-collar workers, who elected him as he called to protect U.S. manufacturing.

U.S. Steel has not publicly communicated any details of a revamped deal to investors. Nippon Steel issued a statement approving of the proposed “partnership” but also has not disclosed terms.

State and federal lawmakers who have been briefed on the matter describe a deal in which Nippon will buy U.S. Steel and spend billions on U.S. Steel facilities in Pennsylvania, Indiana, Alabama, Arkansas and Minnesota. The company would be overseen by an executive suite and board made up mostly of Americans and protected by the U.S. government’s veto power in the form of a “golden share.”

Unionized steelworkers said there is some split opinion in the ranks over Nippon Steel’s acquisition, but that sentiment has shifted over time as they became more convinced that U.S. Steel would eventually shut down their Pittsburgh-area plants.

Clifford Hammonds, a line feeder at the plant where Trump spoke, said at the very least the deal will help upgrade the aging plant and help increase production.

“It’s putting money back into the plant to help rebuild it, because this plant is old, it’s falling apart. We ain’t really producing as much as we should be because, like I said, this place is old. It’s falling apart. We need some type of investment to fix the machines that we’ve got working,” Hammonds said.
