Mexico and Brazil Push Back as U.S. Restores Full Section 232 Tariffs
U.S. President Donald Trump has reinstated the full 25% steel tariffs originally imposed in 2018 under Section 232 steel tariffs, citing national security concerns amid a surge in U.S. steel imports 2025. The executive order, signed on Monday, February 10, eliminates previous exemptions and alternative agreements, restoring the tariffs’ full impact. The decision follows a recommendation from U.S. Secretary of Commerce Howard Lutnick.
Under the new directive, all tariff exclusions will expire on March 12, 2025, affecting steel imports from all countries, including key U.S. trade partners such as Canada, Mexico, Brazil, and the European Union.
The move aims to counter the global steel surplus, exacerbated by China’s steel exports, which reached 114 million tonnes in 2024. The administration also pointed to an 18% rise in Canadian steel imports since 2018 as further justification for reinstating the tariffs.

Industry Reactions: Winners and Losers
The expanded Section 232 steel tariffs now also apply to derivative steel products, a measure intended to boost domestic manufacturing and prevent foreign countries from bypassing direct tariffs by exporting finished goods instead.
“This is a very significant action,” said Christopher Weld, a trade policy attorney at Wiley Rein in Washington, D.C. “The original Trump steel tariffs 2025 had a major impact in 2018, leading to increased U.S. steel industry investments and capacity. Over time, its benefits were weakened by alternative agreements, but this order aims to restore its full effect.”
However, not all industry players are on board. Manufacturers reliant on steel imports warn that the tariffs will lead to higher costs, outdated pricing models, and supply chain disruptions.
“It may be great news for the few domestic steel mills that will increase their prices by 25%, but for thousands of manufacturers downstream, this is a disaster,” said Doug Watts, CEO of Metalworking Group. “Ultimately, these costs will be passed down to the U.S. consumer.”
Mexico and Brazil Brace for Economic Impact
Among the most affected nations is Mexico, the third-largest supplier of U.S. steel imports in 2025, accounting for 12.2% of total imports. Mexican officials condemned the tariffs as “unjust”, with Economy Minister Marcelo Ebrard vowing to seek diplomatic solutions.
Ahead of the tariffs, Mexican steel exports surged to their highest level since April 2024, with U.S. buyers importing 407,000 tons in January—a 10% year-over-year increase—indicating a rush to secure supply before the new trade barriers take effect.
Brazil, another major steel supplier to the U.S., is pushing for negotiations. According to Aço Brasil, the country’s steel industry association, the U.S. has historically maintained a $6 billion annual trade surplus with Brazil, including a $3 billion surplus within the steel supply chain.
“In 2024, the U.S. imported 5.6 million tonnes of semi-finished slabs, a critical material that American mills rely on due to insufficient domestic production. Brazil supplied 3.4 million tonnes under a previous quota agreement,” Aço Brasil stated.
The association refuted U.S. claims of trade circumvention, arguing that Brazilian steel exports comply with all existing trade rules.
A Brazilian steel exporter, speaking anonymously, warned of unintended consequences:
“The U.S. lacks spare capacity to replace imports, so they will either have to ramp up domestic production significantly or continue importing at a much higher cost.”
What’s Next? Market Uncertainty Looms
With the Trump steel tariffs 2025 set to take full effect, analysts predict volatility in steel prices and increased pressure on U.S. manufacturers. Some expect retaliatory measures from affected nations, particularly Mexico and Brazil, which may target U.S. agricultural and industrial exports in response.
Meanwhile, the U.S. steel industry—particularly upstream producers—welcomed the decision. Kevin Dempsey, president of the American Iron and Steel Institute, praised the move, calling it “a step toward leveling the playing field for American steelmakers.”
As global trade tensions escalate, the full economic impact of these tariffs remains uncertain, but one thing is clear: the stakes are high for businesses on both sides of the border.
