The Future of Reciprocal Tariffs and Emerging Possibilities Beyond IEEPA Section 232

With the Trump administration’s 2025 “reciprocal tariff” program under legal attack, its trade team has signaled it will immediately seek alternative legal grounds if the Supreme Court invalidates the use of the International Emergency Economic Powers Act (IEEPA).

U.S. Reciprocal Tariff Actions – Latest Developments

Since September 2025, the United States has significantly expanded its use of trade measures under Section 232 of the Trade Expansion Act of 1962, alongside the formal implementation of elements of the new EU–U.S. trade deal. The Department of Commerce also initiated several national security-related tariff investigations into a broad swath of industrial and medical products, while regulatory notices set up procedures to widen existing tariffs. Concurrently, U.S. authorities announced tariff schedule changes to fulfill the recent U.S.–EU deal, cutting duties on many European exports. These developments occur against a backdrop of high-stakes litigation over executive tariff authority, raising important questions of constitutional and statutory power.
