“We are going to be imposing a 25% increase. We’re going to bring it from 25% to 50% – the tariffs on steel into the United States of America, which will even further secure the steel industry in the United States,” he said at a rally in Pennsylvania.
Trump announced the higher tariffs just outside Pittsburgh, where he was talking up an agreement between Nippon Steel and US Steel. Trump said the USD 14.9 billion deal, like the tariff increase, will help keep jobs for steel workers in the US.
He later posted on social media that the increased tariff would also apply to aluminium products and that it would take effect on Wednesday.
Shares of steelmaker Cleveland-Cliffs Inc surged 26% after the market close as investors bet the new levies will help its profits.
Canada’s Chamber of Commerce quickly denounced the tariff hike as “antithetical to North American economic security.”
“Unwinding the efficient, competitive and reliable cross-border supply chains like we have in steel and aluminium comes at a great cost to both countries,” Candace Laing, president of the chamber, said in a statement.
Australia’s centre-left government also condemned the tariff increase as “unjustified and not the act of a friend.”
“They are an act of economic self-harm that will only hurt consumers and businesses who rely on free and fair trade,” Trade Minister Don Farrell said in a statement.
Australia, a key US security ally in the Indo-Pacific, would “continue to engage and advocate strongly for the removal of the tariffs,” Farrell said.
Trump spoke at US Steel’s Mon Valley Works, a steel plant that symbolizes both the one-time strength and the decline of US manufacturing power as the Rust Belt’s steel plants and factories lost business to international rivals. Closely contested Pennsylvania is also a major prize in presidential elections.
The US is the world’s largest steel importer, excluding the European Union, with a total of 26.2 million tons of imported steel in 2024, according to the Department of Commerce.
As a result, the new tariffs will likely increase steel prices across the board, hitting industry and consumers alike.
Steel and aluminium tariffs were among the earliest put into effect by Trump when he returned to office in January. The tariffs of 25% on most steel and aluminium imported to the US went into effect in March, and he had briefly threatened a 50% levy on Canadian steel but ultimately backed off.
Under the so-called Section 232 national security authority, the import taxes include both raw metals and derivative products as diverse as stainless steel sinks, gas ranges, air conditioner evaporator coils, horseshoes, aluminium frying pans and steel door hinges.
The 2024 import value for the 289 product categories came to USD 147.3 billion with nearly two-thirds aluminium and one-third steel, according to Census Bureau data retrieved through the US International Trade Commission’s Data Web system.
By contrast, Trump’s first two rounds of punitive tariffs on Chinese industrial goods in 2018 during his first term totaled USD 50 billion in annual import value.
