The Trump administration is facing over 2,000 lawsuits over tariff refunds, and this may just be the tip of the iceberg.

In the days following the Supreme Court ruling that most of Trump's tariffs were unconstitutional, over 100 companies have filed new lawsuits, raising concerns that even though the government has collected billions of dollars in tariffs, they will not easily be refunded. Many publicly traded companies and well-known brands have also joined the fray. FedEx filed a lawsuit on Monday, followed by Dyson, Dell, Bausch & Lomb, Brooks Brothers, and Sol de Janeiro USA Inc. Shoe company On Holding AG and the subsidiary of cosmetics giant L'Oreal have also filed lawsuits to reclaim previously paid import duties. Supreme Court justices have remained silent on the issue of refunds, leaving the matter to be handled by the U.S. Court of International Trade in New York. The Justice Department will weigh in on the next steps in the Supreme Court case on Friday, which may indicate the government's willingness to act quickly to address the growing number of claims. Trump has previously hinted that the government may oppose refunds, or at least not easily allow importers to receive the money. In the past 10 months, these businesses have paid over $170 billion in tariffs. Following the February 20 ruling, Trump said, "I think this will have to be resolved through litigation," speculating that it may take years. The latest batch of cases has brought the total number of tariff lawsuits to over 2,000. This is a heavy burden for the trade court, and the number only represents a small portion of the hundreds of thousands of importers affected by the Supreme Court ruling.
