Countries that arm Iran could see the cost of doing business with the US double, if President Trump gets his way. In a Truth Social post Wednesday, the president vowed a 50% tariff on all imports from any nation that supplies military weapons to Tehran, saying it would take effect "immediately" and come with "no exclusions or exemptions," CNBC reports.
- It's not clear what legal authority the tariffs would be applied under. The administration reconstituted its tariff system using existing trade laws after the Supreme Court struck down most of its earlier "reciprocal" duties in February. Current measures already hit many metals products with tariffs of 25% to 50%, and a 100% levy on patented pharmaceuticals for larger drugmakers is set to begin in July.
