Lawsuit

, Costco asks the court to rule the tariff orders invalid, bar Customs from applying the emergency tariffs to future shipments, and require the government to refund all duties already paid under the program.

Costco’s challenge places the company among a growing list of businesses contesting the legality of Trump’s tariff actions.

Learning Resources, Inc., a manufacturer of educational toys and classroom supplies, sued earlier this year, warning that the emergency tariffs would sharply increase its annual duty costs.

V.O.S. Selections, Inc., a wine and spirits importer, has already secured significant court victories striking down the tariff orders, pushing the broader issue up to the Supreme Court.

Other importers — including clothing brands, automotive-parts suppliers, and consumer-goods distributors — have filed similar challenges, arguing the emergency tariffs caused sudden price hikes and supply-chain disruptions they could not absorb.

Costco’s suit leans on several of those earlier rulings. Both the Court of International Trade and the Federal Circuit previously determined that the emergency-powers law used by Trump does not authorize tariffs.

But the company argues those wins do not automatically guarantee refunds unless each importer files its own case before its entries are finalized.

The Supreme Court heard arguments on the larger legal question last month, with a decision expected soon.

That ruling could shape the pace of Costco’s Lawsuit — and determine whether dozens of other companies will have a chance to recoup duties they contend were imposed without legal authority.
