Costco Wholesale Corp. joined a fast-growing list of businesses suing the Trump administration to ensure eligibility for refunds if the US Supreme Court strikes down the president’s signature global tariffs policy.

The nation’s biggest warehouse club chain is among dozens of companies to file lawsuits in a US trade court since late October challenging President Donald Trump’s use of an economic emergency powers law to impose the levies, according to court records. It’s one of the biggest corporate players to jump into a fight largely driven this year by small businesses and Democratic state officials.

The Supreme Court heard arguments on Trump’s tariffs on Nov. 5. The justices put the fight on a fast-tracked schedule but didn’t say when they intend to rule. In the meantime, businesses of all sizes have brought cases pressing similar legal claims with the goal of avoiding uncertainty about their eligibility for refunds if the court rules against Trump.

Costco’s lawyers wrote that the complaint, filed on Nov. 28 in the US Court of International Trade, was prompted due to the uncertainly that refunds will be guaranteed for all businesses that have been paying duties if the Supreme Court declares the tariffs unlawful.
