Summary

The U.S. Supreme Court's recent ruling in *Learning Resources, Inc. v. Trump* invalidated tariffs imposed by the Trump Administration under the International Emergency Economic Powers Act (IEEPA), creating significant refund opportunities for businesses. The Court determined that IEEPA was improperly used for broad, peacetime tariffs, requiring explicit Congressional authority for such measures. While IEEPA-based tariffs are struck down, other regimes like Sections 232, 301, and 122 of the 1974 Trade Act remain in effect. The current administration is already signaling a pivot to Section 122 for new global tariffs, indicating a shifting trade policy landscape. Businesses must act quickly to claim refunds, reassess financial models, and prepare for ongoing tariff changes, which impact landed costs, margins, and contractual agreements.

Key takeaway

For corporate tax and trade leaders managing international trade, you must prioritize filing protective claims for IEEPA-based tariff refunds before statutory deadlines expire. Simultaneously, update your financial and transfer pricing models to reflect potential tariff changes and new global duties, ensuring your intercompany agreements align with refund entitlements. This proactive approach will help your organization mitigate risks and capitalize on opportunities in a volatile trade environment.
