IEEPA reciprocal tariffs (struck down by the Supreme Court)

The April 2025 'Liberation Day' executive order imposed a 10% baseline tariff on nearly all imports plus higher country-specific rates. After a year of pauses, extensions, and litigation, the Supreme Court ruled 6–3 on February 20, 2026 that IEEPA does not authorize tariffs, voiding the entire program. Duties already paid — industry estimates run as high as $175 billion — are potentially refundable; the administration replaced part of the program with a Section 122 surcharge the same day.
