Steel and Aluminum Tariffs: Trade War With Allies, WTO Violations, Economic Disruption
The Section 232 tariffs were challenged immediately as legally dubious — U.S. national security law did not contemplate allies as threats, and Canada, Germany, South Korea, and Japan supply steel and aluminum to U.S. defense contractors. The EU, Canada, and Mexico all retaliated with targeted tariffs on politically sensitive U.S. products (Bourbon, Harley-Davidson motorcycles, orange juice, soybeans). The broader China trade war — separate from the steel tariffs — involved escalating rounds of tariffs reaching 25% on $250 billion in Chinese goods; China retaliated against agricultural products; the U.S. government paid $28 billion in direct payments to American farmers to compensate for lost Chinese export markets.

trump-steel-aluminum-tariffs-trade-war- Victims
- American manufacturers dependent on imported steel and aluminum who faced higher input costs; American farmers who lost Chinese export markets and received government compensation payments; allied relationships strained by tariffs on security partners
- Alleged responsible parties
- Donald Trump, President; directed Section 232 tariffs on allies; escalated China trade war through multiple rounds of tariffs— White House
- Peter Navarro, White House trade advisor; principal architect of tariff strategy; credentialed economist whose views were far outside mainstream economics— White House National Trade Council
Key points
- The Section 232 tariffs were applied to Canada, Mexico, the EU, Japan, and South Korea — close military allies — on national security grounds; the legal theory required arguing that allied countries whose steel is used in U.S. defense procurement posed national security threats; the legal basis was widely mocked, including by some Republicans
- Canada, Mexico, and the EU immediately imposed targeted retaliatory tariffs on politically sensitive American products — Bourbon (Kentucky), Harley-Davidson motorcycles (Wisconsin), orange juice (Florida), and soybeans — chosen to maximize political pressure on Republican constituencies
- The broader China trade war — launched separately beginning in 2018 — reached 25% tariffs on approximately $250 billion in Chinese goods; China retaliated primarily against American agricultural exports; the Peterson Institute estimated the trade war cost the average American household approximately $831 per year
- The U.S. government paid $28 billion in emergency Market Facilitation Program subsidies to American farmers to compensate for lost export markets — payments that critics noted were larger than the 2009 auto industry bailout; the money came from tariff revenue (primarily paid by American importers and consumers)
- The WTO Panel issued a July 2022 ruling finding that the Section 232 steel and aluminum tariffs violated U.S. obligations under GATT; the U.S. appealed; the ruling was limited in immediate practical impact since the Biden administration also maintained tariffs against China
- Harley-Davidson announced in June 2018 that it would shift some manufacturing overseas to avoid European retaliatory tariffs — a direct economic consequence of the tariff policy that Trump angrily attacked, threatening to tax Harley-Davidson for the decision
Overview
Trump imposed 25% tariffs on steel imports from close military allies and called it a national security measure. Canada, Germany, and Japan supply steel to U.S. defense contractors. Calling allied nations national security threats in order to invoke trade law authority was a legal theory that most trade lawyers found implausible.
The WTO agreed. It didn't matter much.
The "National Security" Theory
Section 232 of the Trade Expansion Act allows the president to impose tariffs for national security reasons. It was designed for scenarios like a hostile nation cutting off access to strategic materials.
Trump's team applied it to Canada — which shares the world's longest undefended border with the United States, which is in NATO, which has fought alongside the U.S. in every major conflict since World War I. Canadian Trade Minister Freeland called the argument "absurd." U.S. Senate Republicans agreed.
The Retaliation
Allied governments are not passive. Canada, Mexico, and the EU designed their retaliatory tariffs with precise political targeting: Bourbon comes from Kentucky (Mitch McConnell's state), Harley-Davidsons are made in Wisconsin (a key swing state), orange juice is from Florida, soybeans are from the Midwest. The tariffs mapped the Electoral College.
The Farm Subsidies
The China trade war cost American farmers their largest export market. To compensate, the U.S. government paid $28 billion in direct agricultural subsidies — more than the 2009 auto industry bailout. The money came from tariff revenue. Tariff revenue comes from American importers. American importers pass costs to American consumers.
The tariffs were a tax on Americans paid partly back to farmers for the harm the tariffs caused.
