If you thought the tariff saga was winding down, think again. On May 7, 2026, the US Court of International Trade struck down a second round of sweeping Trump administration tariffs — following the Supreme Court’s February 6-3 decision against IEEPA-based tariffs. The tariff whipsaw has left businesses struggling to plan and consumers absorbing costs that haven’t unwound the way many expected.
On paper, the court victories should mean lower prices. In practice, supply chains don’t reverse overnight, and some price increases have already been permanently baked in.
The CIT panel found the president lacks blanket statutory authority to impose open-ended, economy-wide import levies without specific Congressional authorization. Still in play: sector-specific auto (25%), steel, and aluminum tariffs under Section 232 of the Trade Expansion Act — on more solid legal footing.
Courts can strike down tariffs, but they can’t mandate that prices fall. The Tax Foundation estimated Trump-era tariffs cost the average US household roughly $1,500 in 2026 even accounting for some rollbacks. And with a potential 25% auto tariff on European vehicles looming in July, the story isn’t over.
Companies have responded three ways: absorbing costs (hurting margins), raising prices (hurting consumers), or reshuffling supply chains. The legal uncertainty has made all three strategies harder. A business that moved manufacturing to avoid China tariffs now asks: if the legal landscape keeps shifting, which moves are permanent?
Not automatically or immediately. Supply chains are slow to adjust, and retailers rarely pass savings through as quickly as they pass cost increases. Expect gradual, partial relief in some categories over months — not weeks.
No. The rulings apply to tariffs imposed under IEEPA authority. Sector-specific tariffs on steel, aluminum, and autos under Section 232 remain legally distinct and have not been overturned.
The administration could seek Congressional authorization. No such legislation has been introduced as of May 2026.
