Why fashion companies are suing before the Supreme Court’s decision

The U.S. Supreme Court is preparing to rule on the legality of President Donald Trump’s sweeping tariffs. At the same time, significant legal mobilization is taking place across global fashion companies and supply chains. According to a Bloomberg report, more than 1,000 companies have now filed suit. They are positioning themselves for what could be one of the biggest battles over duty drawbacks in U.S. history.

Most of the lawsuits have been filed since November. They reflect growing confidence that the court could invalidate Trump’s use of a 1977 emergency law to justify sweeping import tariffs. Should this happen, the question will quickly shift from legality to logistics: who gets a refund, how and under what conditions?

Bloomberg estimates that around $133 billion in tariffs were collected under the emergency powers alone. These are spread across hundreds of thousands of importers and tens of millions of deliveries. The plaintiffs primarily include companies in the clothing, textiles, shoes, car parts, cosmetics and consumer goods sectors. This underscores how deeply tariffs intervene in everyday categories.

For much of 2025, many companies held back. They feared political retaliation or damage to their image. But after Supreme Court justices openly questioned the government’s powers during hearings in November, reluctance gave way to urgency. Filing a lawsuit, lawyers told Bloomberg, is less a protest than an insurance policy. Without a pending lawsuit, companies may not have a clear path to reimbursement if repayments are processed through the courts.

Out of fear of retaliation

Well-known names — from large retailers to cosmetics brands to shoe labels — are now joined by smaller, founder-led companies. Some report delayed hiring, higher prices for consumers or lower imports as a direct result of tariff costs. The Bloomberg report shows how these pressures are playing out unevenly across the market. Smaller companies are hit hardest, even though larger corporations can claim much larger amounts back.

The Trump administration has warned that forced refunds would undermine national security. It has signaled that it may seek to reintroduce the tariffs under alternative legal arrangements if emergency powers are blocked. However, commercial law experts note that these options are slower, more limited and easier to challenge.

Even a decision against the tariffs would not provide immediate relief. The Supreme Court is expected to leave the processing of refunds to lower courts. This will likely trigger years of additional litigation. There is precedent, particularly a case from the 1990s, that led to mass repayments. However, there has been nothing on this scale before.

For now, companies are preparing documentation, checking import documents and preparing for uncertainty. As Bloomberg’s analysis shows, the litigation has become a reflection of the modern global economy: it is fragmented, interdependent and exposed to high political risk.

Whether the court will side with the government or the plaintiffs remains to be seen. However, the decision will redefine cost structures in the fashion, retail and manufacturing industries for years to come.
