New 10-12.5% Tariffs Face Legal Challenges, Economists Warn

For legal departments and regulatory professionals, the Trump administration's latest tariff maneuver is a case study in executive trade power. By replacing a temporary 10% levy with permanent tariffs of 10-12.5%, framed as legally durable, the administration is bracing for inevitable litigation. Companies reliant on imports must now reassess compliance risks and potential exposure to court rulings that could unravel or cement these trade barriers.

On July 25, 2026, the Trump administration replaced a temporary 10% tariff with a new set of permanent levies ranging from 10% to 12.5% on imports from dozens of countries. This move, announced by the White House on July 24, is designed to be more legally durable and marks a continuation of President Trump's aggressive trade policy in his second term, against a backdrop of economic uncertainty fueled by the war with Iran and persistent inflation concerns. The new tariffs, while only marginally higher than the ones they replace, still raise the average U.S. tariff rate to 11%, according to the Budget Lab at Yale University, up from when the term began.

This tariff escalation comes at a time when American households are already under strain. The national average gasoline price has surged back above $4 per gallon, according to AAA, after briefly dipping below that level in late June, as crude prices spike amid Iran tensions. Simultaneously, the average 30-year mortgage rate hit its highest in nearly a year, exacerbating housing affordability. These cost-of-living pressures, combined with tariffs that act as a tax on imported consumer goods, threaten to reignite inflation just as it had shown signs of easing. The administration argues tariffs will benefit the U.S. economy and workers by protecting domestic industries, but economists widely contend that the burden falls disproportionately on consumers through higher prices and on businesses through disrupted supply chains.

From a legal perspective, the administration has sought to make the new tariffs more ‘legally durable’—implying they are structured to withstand court challenges that have plagued previous trade actions. However, economists and legal experts anticipate continued litigation, particularly if the tariffs are seen as exceeding executive authority or violating trade agreements. The carveouts suggest a careful calibration to avoid immediate economic shock, yet the broader impact is a steady drag on economic growth.
