The Trump administration has refunded approximately $100 billion in tariffs since the U.S. Supreme Court invalidated a significant portion of the president's tariff regime. Customs officials confirmed that the refunds were issued after the nation's top court ruled against the administration's use of emergency powers to impose duties on numerous trade partners.

The Trump administration had initially collected around $166 billion from U.S. importers before the Supreme Court's 6-3 ruling in February. This decision found that President Trump had exceeded his authority by invoking the 1977 International Emergency Economic Powers Act (IEEPA) to implement fentanyl-related tariffs on Canada, Mexico, and China, as well as broader "reciprocal" tariffs affecting over 90 countries.

In a Tuesday court filing, U.S. Customs and Border Protection (CBP) disclosed that more than three-quarters of the $128.68 billion in tariff revenues designated for "potential and certified refunds" had been returned. Brandon Lord, executive director of CBP’s Trade Policy and Programs directorate, stated in the filing with the U.S. Court of International Trade that the agency's financial system receives updates from the Treasury indicating these refunds are being disbursed.

President Trump had strongly denounced the Supreme Court's ruling at the time, criticizing the justices who sided against his administration. However, the ruling did not impact tariffs imposed on specific industries under the 1962 Trade Expansion Act, such as those on steel, automobiles, and copper.

Following the Supreme Court's decision, the U.S. Court of International Trade issued a ruling in March mandating refunds for companies affected by the invalidated tariffs. Despite this, President Trump has continued to introduce new tariffs. Last month, his administration announced levies ranging from 10 to 12.5 percent on imports from countries accused of insufficient action against forced labor.

This latest action has drawn legal challenges. On Monday, a coalition of 25 U.S. states, including New York, California, Arizona, and Colorado, filed a lawsuit against the new tariffs. They argue that these measures serve as a pretext to re-impose duties that were previously struck down by the Supreme Court in February.

International trade partners have reacted to the Trump administration's continued use of tariffs. The introduction of new levies related to forced labor claims has prompted questions and concerns from various countries, highlighting ongoing tensions in global trade relations.
