<h1>President orders steep emergency tariffs under Section 232 and IEEPA, sparking commercial chaos and likely industry litigation</h1> The president announced steep new tariffs via social media - 100% on pharmaceuticals, 50% on kitchen cabinets and bathroom vanities, 30% on upholstered furniture, and 25% on heavy trucks - to take effect within days, creating immediate commercial and legal uncertainty. The administration cites national security and is using Section 232 of the Trade Expansion Act and prior national-emergency IEEPA measures as authorities; courts have already invalidated some IEEPA-based tariffs and the Supreme Court is hearing an appeal. Key legal issues include whether tariffs can stack on existing duties, the sufficiency of national-security justifications, procedural detail gaps, and likely litigation by affected industries.
