Supreme Court Strikes Down IEEPA Tariffs: Reshaping Supply Chains and Freight Lanes in 2026

In a pivotal 6-3 decision issued on February 13, 2026, the U.S. Supreme Court struck down President Donald Trump's broad tariffs imposed under the International Emergency Economic Powers Act (IEEPA). The ruling, authored by Chief Justice John Roberts, declared that IEEPA does not grant the executive branch authority for such sweeping, retaliatory trade duties—a significant blow to the administration's trade strategy since February 2025. As supply chains and freight markets continue to adjust from a year of tariff-driven disruptions, this decision signals potential relief but also lingering uncertainty.

The cases, Learning Resources Inc. v. Trump and Trump v. V.O.S. Selections Inc., originated from challenges by an educational toy company and a wine importer. The Court invalidated country-specific reciprocal tariffs, including rates as high as 34% on Chinese imports and 25% duties on goods from Canada, Mexico, and China linked to drug trafficking enforcement. However, tariffs enacted under separate authorities—like Section 232 duties on steel and aluminum—remain intact.

The Financial and Economic Stakes

The numbers are eye-opening: The Penn Wharton Budget Model estimates these IEEPA tariffs generated about $500 million in daily revenue, totaling roughly $179 billion since their inception. These costs were borne by American importers, not foreign exporters, fueling calls for refunds. The coalition We Pay the Tariffs, representing over 800 small businesses, urged the administration for "full, fast, and automatic" reimbursements. The Court of International Trade is poised to issue implementation orders, potentially directing U.S. Customs and Border Protection on refund processes.

For businesses, this could mean billions in reclaimed funds—providing a much-needed cash infusion amid ongoing economic pressures.

Freight and Supply Chain Implications: A Delayed Tailwind

Freight markets, already distorted by tariffs, stand to benefit from the ruling, though impacts won't materialize overnight. Project44 data reveals U.S. imports from China plummeted 28% year-over-year in 2025, with overall ocean container volumes to the U.S. dropping 14% as companies maintained leaner inventories and diversified sourcing.

Paul Brashier, VP of Drayage and Intermodal at ITS Logistics, noted: "If IEEPA tariffs are removed from all imported goods, there would certainly be an increase in imports, especially for goods recently being sourced in higher-tariff countries." However, with ocean transit times averaging 45 days, any surge in volumes may not hit U.S. ports until late March or April 2026.

This could lead to:

• Increased import flows — Particularly from Asia, potentially boosting ocean and intermodal freight demand.

• Supply chain reconfiguration — Businesses may reverse nearshoring or reshoring efforts, reevaluating lanes to capitalize on lower costs.

• Freight rate pressures — Higher volumes could strain capacity, especially in trucking and rail, leading to spot rate volatility.

Yet, challenges persist: Lean inventory strategies may linger due to uncertainty, and global disruptions (e.g., geopolitical tensions) could temper rebound enthusiasm.

The Trade War Isn't Over: What's Next?

President Trump labeled the decision a "disgrace" and hinted at a "backup plan," likely involving alternative statutes like Section 301 (USTR-led unfair trade investigations) or expanded Section 232 (national security-based duties). These paths come with procedural hurdles and narrower scopes, potentially slowing implementation.

As eMarketer's Zak Stambor put it: "The decision provides some near-term relief, but it does not eliminate the broader trade policy uncertainty facing retailers and brands." Shippers should prepare for possible new tariffs or retaliatory measures, maintaining flexible sourcing and logistics strategies.
