Supreme Court Strikes Down IEEPA Tariffs; Trump Pivots to Section 122
The US Supreme Court ruled 6-3 that the executive branch cannot use the IEEPA to impose broad-based tariffs, leading the Trump administration to immediately pivot to Section 122 of the Trade Act of 1974. This shift introduces a 10% global tariff surcharge and a new 150-day window of regulatory uncertainty for global supply chains.
