Analysis: Trump’s Section 301 Tariffs Face Legal and Trade Challenges
New analysis argues Trump’s Section 301 tariffs are legally flawed and risky.
Why it matters: Trade lawyers and corporate legal teams must navigate the uncertainty from shifting tariff rules and international backlash. This legal critique exposes risks in cross-border supply chains and regulatory compliance.
- Trump imposed 10%–12.5% tariffs on imports from 60 countries, covering 99% of U.S. imports.
- Supreme Court ruled in February 2026 that IEEPA doesn’t authorize tariffs, invalidating the initial tariff structure.
- Section 122 tariffs imposed in February 2026 were struck down by the U.S. Court of International Trade in May as unlawful.
- The administration shifted to Section 301 tariffs citing unfair trade practices, but critics question the forced labor rationale and legality.
On July 23, 2026, President Trump announced new tariffs of 10% to 12.5% on imports from 60 trading partners, representing 99% of U.S. imports, justified under Section 301 of the Trade Act of 1974. These followed prior tariff actions that faced legal setbacks.
Earlier, the Supreme Court ruled on February 20, 2026, that the president could not impose tariffs under the International Emergency Economic Powers Act (IEEPA). Chief Justice John Roberts noted that "IEEPA contains no reference to tariffs or duties." This decision invalidated the administration's original tariff approach.
Subsequently, the administration imposed 10% tariffs under Section 122 of the Trade Act in February 2026, aiming to address balance-of-payments deficits. However, the U.S. Court of International Trade struck down these tariffs in May as unlawful because the statutory criteria were unmet.
In response, the administration turned to Section 301, permitting tariffs against unfair trade practices, to reimpose tariffs and recoup revenue. Critics argue the forced labor justification may mask aggressive economic policies and risk retaliation from key partners like Brazil and Chile, who have condemned the move as arbitrary (AP News).
Geoffrey Gertz of CNAS highlighted the administration's legal pivot as an effort to "mostly, though not entirely, recreate previous tariffs," blending economic aims with legal maneuvering (CNAS Insights).
Exemptions remain for critical imports to avoid economic disruption, but the legal and trade uncertainties pose challenges for businesses and legal practitioners monitoring international trade compliance and risks.
By the numbers:
- 10% to 12.5% — new tariff rates imposed on imports from 60 U.S. trading partners
- 99% — proportion of all U.S. imports affected by the tariffs
- February 20, 2026 — date Supreme Court ruled IEEPA does not authorize tariffs
- May 8, 2026 — date U.S. Court of International Trade struck down Section 122 tariffs
Yes, but: While the Section 301 tariffs address perceived unfair trade practices, the lack of clear legal grounding and widespread international criticism complicate enforcement and risk retaliation.
What's next: Watch for ongoing legal challenges to Section 301 tariffs and international responses from affected trade partners.
