Trump Just Doubled Tariffs on Steel and Aluminum Coming Into June

April 23, 2026

When Tariff Policy Gets Stupider

According to the UK Parliament House of Commons Library, "From 4 June, the US doubled its import tariffs on steel and aluminium to 50%." That's right. Starting in June, any steel or aluminum imported into the United States is subject to a 50% tariff.

For context, previously the tariffs were lower (25% or so, depending on the source). Now Trump's administration is doubling them to 50%. This is what happens when tariff policy becomes ideological rather than strategic.

Why This Is Bad Economics

Steel and aluminum are inputs for manufacturing. Construction companies use steel. Car manufacturers use steel and aluminum. Every manufacturing company in America uses these materials. Adding a 50% tariff on imported steel and aluminum makes those materials 50% more expensive.

That cost gets passed on to consumers in higher prices for cars, construction, appliances, and basically everything that uses steel or aluminum.

The Trump administration probably justifies this by saying it "protects American steel and aluminum." But American steel and aluminum producers can't meet total U.S. demand. So tariffs don't protect American industry—they just make American industry more expensive and less competitive internationally.

The Business Problem

American manufacturers who use steel and aluminum have three choices: 1) Buy expensive American steel/aluminum and pay tariffs anyway (if they buy imports), making their products more expensive and less competitive 2) Move manufacturing to another country that doesn't have these tariffs, moving jobs out of America 3) Absorb the cost and have lower profit margins None of these are good options. That's why tariffs on inputs for manufacturing are bad economic policy.

The Political Appeal

Trump likes tariffs because they sound tough. "We're protecting American steel!" sounds good in a campaign speech. People imagine steelworkers going back to work in Pennsylvania steel mills.

What actually happens: construction gets more expensive, cars get more expensive, manufacturing moves overseas, and American steelworkers don't actually get more jobs because factories move to where tariffs aren't destroying their competitiveness.

What Happens in June?

Starting June 4th, every container of imported steel or aluminum faces a 50% tariff. Prices go up immediately. American companies that depend on imported materials get hit hardest. Construction projects get more expensive. Consumers pay more for everything that uses steel or aluminum.

The Trump administration probably has some talking points about how this "brings back American manufacturing." Those talking points will be wrong. Manufacturing won't come back. Prices will just go up.
