If a derivative product has more than 15% steel, aluminum, or copper by weight, it'll face a new 25% tariff on its total value.
Items made abroad entirely from U.S.-sourced metals get a break with just a 10% tariff.
There's also good news for certain metal-intensive industrial and electrical grid equipment: their tariffs drop from 50% to 15% through 2027.
The whole idea is to make rules clearer and boost revenue while giving some industries room to grow.
