Since taking office in January 2025, President Trump has fundamentally reshaped the US tariff landscape. From the sweeping IEEPA reciprocal tariffs of April 2025 to the Supreme Court ruling that struck them down in February 2026, and the rapid Section 122 replacement signed the same day, the pace of change has been relentless. This guide provides a comprehensive, up-to-date overview of every tariff program, what's currently in effect, what was invalidated, and what importers need to know right now.
Timeline: Trump Tariffs from Inauguration to Today
January 2025: Trump takes office, immediately signals aggressive trade posture. February 2025: Executive orders direct USTR to review all trade relationships and identify 'non-reciprocal' tariff arrangements. March 2025: Section 232 investigations expanded to cover copper, semiconductors, and lumber. April 2, 2025: 'Liberation Day' — Trump signs sweeping IEEPA reciprocal tariffs on 80+ countries. Rates range from 10% baseline to 46% (Vietnam), 36% (Thailand), 32% (Taiwan), 25% (South Korea), 20% (EU), and more. April 9, 2025: 90-day pause on higher rates for most countries; 10% baseline remains. China excluded from pause. June 2025: Section 232 tariffs on steel and aluminum doubled from 25% to 50%. New Section 232 tariffs imposed: copper 50%, semiconductors 25%, lumber 10%. August 2025: China tariff truce — reciprocal rates reduced while negotiations continue. October 2025: Court of International Trade rules IEEPA tariffs unconstitutional. November 2025: Federal Circuit upholds CIT ruling. February 20, 2026: Supreme Court rules 6-3 in V.O.S. Selections Inc. v. United States — IEEPA tariffs permanently invalidated. Same day: Trump signs 10% global tariff under Section 122 (150-day limit). March 2026: New Section 301 investigations launched against multiple countries. Section 232 steel and aluminum rates remain at 50%.
What's Currently in Effect (April 2026)
Three separate tariff programs are active right now. First, the Section 122 global tariff of 10% applies to imports from virtually every country. This was signed February 20, 2026, took effect February 24, and expires approximately July 24, 2026, unless Congress extends it. Second, Section 232 tariffs apply to specific products from all countries: steel at 50%, aluminum at 50%, copper at 50%, automobiles at 25%, semiconductors at 25%, and lumber at 10%. These have no expiration date. Third, Section 301 tariffs on China remain in effect, adding 25-100% on covered products. Most Chinese electronics and machinery face 25%, solar panels 50%, and electric vehicles 100%. These three layers stack — meaning a Chinese steel import could face 10% Section 122 + 50% Section 232 + 25% Section 301, for a combined rate of 85%.
What Was Struck Down by the Supreme Court
The Supreme Court's February 2026 ruling in V.O.S. Selections Inc. v. United States permanently invalidated all tariffs imposed under IEEPA authority. This includes: the 10% baseline reciprocal tariff that applied to nearly all countries, all country-specific higher rates (Vietnam 46%, Thailand 36%, Taiwan 32%, South Korea 25%, EU 20%, etc.), the China-specific IEEPA tariffs (10% reciprocal + 10% fentanyl surcharge), and all modifications including the US-China truce adjustments. The Court held that IEEPA grants emergency economic powers but does not authorize tariffs — a power reserved to Congress. This ruling permanently closes the IEEPA path for future tariff actions.
Current Tariff Rates by Country
Here are the effective tariff rates for major US trading partners as of April 2026. China: 10% Section 122 + 25-100% Section 301 = 35-110% effective rate. Canada and Mexico: 0% if USMCA-qualifying (89% of goods), otherwise 10% Section 122. EU countries (Germany, France, Italy, Spain, Netherlands, etc.): 10% Section 122 flat rate. United Kingdom: 10% Section 122 (bilateral trade deal under negotiation). Japan: 10% Section 122 + 25% Section 232 on autos. South Korea: 10% Section 122 flat rate. Taiwan: 10% Section 122 + 25% Section 232 on semiconductors. Vietnam: 10% Section 122 (down from 46% IEEPA). India: 10% Section 122 flat rate. Thailand: 10% Section 122 (down from 36% IEEPA). Bangladesh: 10% Section 122 (down from 37% IEEPA). Ireland: 10% Section 122. All countries face Section 232 rates on steel (50%), aluminum (50%), copper (50%), autos (25%), semiconductors (25%), and lumber (10%) in addition to the above.
Section 232 Tariffs: The Rates That Survived
Section 232 tariffs were not challenged in the SCOTUS case and remain fully in effect. These tariffs are imposed under national security authority and apply universally — no country is exempt. Steel: 50% (doubled from 25% in June 2025). Aluminum: 50% (doubled from 25% in June 2025). Copper: 50% (new, imposed March 2025). Automobiles: 25% (imposed April 2025). Semiconductors: 25% (new, imposed June 2025). Lumber: 10% (new, imposed June 2025). For products covered by Section 232, the anti-stacking rule means you pay Section 232 OR Section 122, whichever is higher — not both. Since all Section 232 rates exceed the 10% Section 122 rate, Section 232 products effectively pay only the Section 232 rate (plus Section 301 if applicable).
Section 301 Tariffs on China: Still in Full Force
Section 301 tariffs on China were imposed under trade law authority (not IEEPA) and were not affected by the Supreme Court ruling. These tariffs target specific product categories based on HTS codes. The 25% bracket covers most electronics, machinery, chemicals, furniture, and consumer goods. The 7.5% bracket applies to some consumer products and textiles. Higher rates target strategic sectors: EV batteries at 25%, solar panels and cells at 50%, electric vehicles at 100%, and certain semiconductors at 50%. The de minimis exemption ($800 threshold) has been eliminated for Chinese imports, meaning all shipments face full tariffs regardless of value.
Key Dates to Watch in 2026
Several critical deadlines could reshape the tariff landscape. July 1, 2026: USMCA joint review begins — could modify rules of origin for autos, digital trade, and agriculture. July 20, 2026: Deadline for new Section 301 investigations launched March 11 — could result in new permanent tariffs on multiple countries. July 24, 2026 (approximately): Section 122 tariff expires unless Congress extends it. This is the most important date for importers. If Congress doesn't act, the 10% global tariff disappears entirely. Various 2026 dates: Court of International Trade hearing challenges to Section 122 from 24 state attorneys general. UK bilateral trade deal negotiations ongoing — could result in reduced or zero tariffs for British goods.
Impact on Importers: What You Should Do Now
Given the current tariff landscape, importers should take several steps. First, audit your supply chain exposure using our tariff calculator to understand your effective rates by country and product. Second, evaluate sourcing alternatives — countries like Vietnam, Thailand, and Bangladesh now face only 10% (down from 36-46% under IEEPA), making them much more competitive against China. Third, check USMCA qualification for any Canada/Mexico imports — the difference between 0% and 10% is significant at scale. Fourth, plan for the July 24 Section 122 expiration — model three scenarios: rates drop to 0%, Congress extends at 10%, or Congress passes higher permanent rates. Fifth, pursue IEEPA refund claims if you paid reciprocal tariffs between April 2025 and February 2026. Sixth, stay current on Section 301 investigations that could impose new permanent tariffs by summer 2026.
Key Takeaway
The Trump tariff regime in 2026 is defined by three layers: 10% Section 122 (temporary, expiring July 24), Section 232 product tariffs (25-50%, permanent), and Section 301 China tariffs (25-100%, permanent). The SCOTUS ruling removed the most aggressive rates, but significant tariffs remain. The biggest uncertainty is what happens after July 24 — importers should prepare for multiple scenarios and use the tools on this site to model their exposure.
