A fresh tariff fight is heading back to federal court over whether the White House used forced-labor concerns to rebuild a trade policy judges had already rejected.
Twenty-five states sued the Trump administration on August 3, challenging tariffs that reach nearly every major U.S. trading partner. The case places President Donald Trump’s economic agenda under renewed pressure less than six months after the Supreme Court ruled that an emergency-powers law did not authorize his earlier worldwide import taxes.
The duties range from 10% to 12.5% and apply to goods from 60 economies, including 59 countries and the European Union. They took effect July 24 and cover partners responsible for about 99.4% of U.S. imports. Importers, retailers, manufacturers and families could all feel the outcome through supply costs and prices.
States Call the Tariffs an Unlawful Replacement

The coalition filed its complaint in the U.S. Court of International Trade. It includes attorneys general from California, New York, Arizona, Illinois, Virginia, Washington and other states, along with the governors of Kentucky and Pennsylvania.
The states argue that the administration used Section 301 of the Trade Act of 1974 as a pretext to continue broad tariffs after losing earlier cases. They want the court to declare the duties unlawful and block enforcement. The complaint also invokes the Administrative Procedure Act, which permits judges to overturn federal actions that violate governing law or required procedures.
New York Attorney General Letitia James said the administration was again trying to “illegally raise taxes on families and businesses.” California Attorney General Rob Bonta called the case Trump’s third attempt to impose sweeping duties after courts rejected two earlier legal theories. The White House disputes those claims.
The Supreme Court Changed Trump’s Tariff Strategy
Trump initially relied on the International Emergency Economic Powers Act, or IEEPA, to impose tariffs on imports from most countries. He argued that trade deficits and drug trafficking created national emergencies requiring aggressive action.
On February 20, the Supreme Court ruled in Learning Resources v. Trump that IEEPA does not authorize presidential tariffs. The justices stressed that the Constitution gives Congress the power to levy duties and that lawmakers had not clearly transferred unlimited tariff authority through the emergency statute.
The administration then moved to temporary 10% tariffs under Section 122 of the Trade Act. The Court of International Trade ruled against that approach in May. An appeals court later stayed the decision while the government’s appeal continues.
Trump next turned to Section 301, a law historically used to respond to unfair foreign trade practices. He used it during his first term to impose major tariffs on China. That history may offer a firmer foundation than IEEPA, but Section 301 carries investigative requirements at the center of the states’ challenge.
Forced Labor Is the White House’s Justification
The Office of the U.S. Trade Representative says the tariffs target countries that fail to impose and enforce bans on imports made with forced labor. USTR says its investigation included two rounds of hearings, more than 2,100 public comments and engagement with trading partners.
Several economies face a 10% tariff because they have forced-labor import restrictions or related trade commitments. Others face 12.5%, while special calculations apply to goods from the European Union, Japan, South Korea, Switzerland and Taiwan. Certain products are exempt, and tariff-rate quotas are planned for some textile-producing countries.
The White House maintains that weak foreign enforcement burdens U.S. commerce and American workers. It argues that Section 301 is a lawful and “legally durable tool” for pressing trading partners to strengthen their rules.
The Lawsuit Targets a Rushed Investigation
The states contend that USTR did not complete the country-specific work Section 301 requires. Their complaint says the administration examined 60 economies in roughly two and a half months, while earlier investigations involving Brazil and China took far longer.
It also alleges that USTR grouped widely different economies into only a few tariff categories, failed to establish benchmarks for removing duties, and did not clearly connect each rate to forced-labor risks in the affected country.
Courts may hesitate to second-guess trade policy, but they can examine whether an agency followed the law Congress wrote. If judges conclude the administration chose worldwide tariffs first and built the investigation around that result, the Section 301 strategy could face serious trouble.
Businesses Face Another Round of Uncertainty

Tariffs are collected from U.S. importers when goods enter the country. Companies must decide whether to absorb the cost, renegotiate with suppliers, cut expenses, or raise prices. Because the duties touch partners supplying nearly all U.S. imports, the uncertainty reaches industries from apparel and electronics to manufacturing and construction.
Businesses are also waiting to learn how previously collected tariffs will be refunded following the Supreme Court decision. Another ruling against the administration could create a second refund process while forcing companies to revise contracts, inventory plans and pricing again.
For consumers, the issue is not only whether tariffs remain. It is whether repeated legal shifts will keep businesses operating under temporary trade rules that change after each major court decision.
The Case Could Redefine Presidential Tariff Power
The administration’s latest defense is stronger on paper because Section 301 expressly permits trade retaliation in certain circumstances. The states’ answer is that an explicit power is not an unlimited one.
The case will test whether a president can turn a targeted trade-enforcement statute into a near-global tariff system by identifying one common foreign practice. It will also test how closely judges may examine the connection between a tariff’s stated purpose and its actual design.
After three statutory approaches in less than a year, the courts are again being asked to draw a line between presidential flexibility in foreign commerce and Congress’s constitutional control over tariffs. For American families and businesses, that line may determine what imported goods cost and how much economic policy can change without a vote in Congress.
