US Tariff Timeline

Global tariffs on steel and aluminum imports. Exemptions granted and revoked for various countries over subsequent years. Raised to 50% globally in June 2025.

USTR imposed 25% tariffs on approximately $200B of Chinese goods, covering a broad range of electronics. Originally 10%, raised to 25% in May 2019. Survived SCOTUS review.

USTR imposed 7.5% tariffs on the first tranche of List 4 goods ($112B). Covers laptops, tablets, Bluetooth devices, video game consoles, and many consumer electronic components.

Trump invoked IEEPA citing fentanyl emergency: 10% tariff on China-origin goods, 25% on Canada and Mexico. Stacked on top of existing Section 301 tariffs for China.

Global reciprocal tariffs imposed on 90+ trading partners. China faced 34% additional. Paused after 90 days at 10% baseline; eventually reinstated Aug 2025. Voided by SCOTUS Feb 2026.

DOC launched Section 232 national-security investigation into semiconductor imports. Preliminary findings pending; tariffs expected to apply to advanced ICs and wafers.

The Supreme Court held 6-3 that IEEPA does not grant the President authority to impose tariffs. All IEEPA-based tariffs were immediately voided. Estimated $160B+ in duties potentially refundable.

Following SCOTUS ruling, Trump signed EO invoking Section 122 to replace IEEPA: 10% global surcharge on most imports. Expires after 150 days unless Congress extends. Exempt: USMCA goods, Section 232 goods, pharmaceuticals (Chapter 30).

Section 122 automatically expires 150 days after the Feb 24, 2026 effective date unless Congress passes legislation to extend it. If expired without replacement, the 10% surcharge drops to 0%.
