Supreme Court Strikes Down IEEPA Tariffs 6–3; $166B in Refunds as US Customs Launches Portal

The US Supreme Court struck down Trump's broad tariffs imposed under the International Emergency Economic Powers Act (IEEPA) in a 6-3 ruling, finding them an unconstitutional usurpation of Congress's tax-setting authority. US Customs subsequently launched an online portal for businesses to claim refunds on the now-nullified tariffs — covering approximately $166 billion across 330,000+ importers and 53 million+ shipments, with refunds expected to be processed within 60-90 days. The ruling left in place Section 232 tariffs on steel, aluminum, and copper (authorized under a separate statute) and did not affect semiconductor, pharmaceutical, or country-specific tariffs imposed under other legal authorities. The decision came as AP-NORC polling showed Trump's economic approval falling to 30% (from 38% in March), with ~75% of Americans describing the economy as 'very' or 'somewhat' poor — driven by Iran war oil prices, tariff-era cost increases, and non-farm payrolls averaging only ~20,000/month since January 2025.
