Costco sues U.S. government over Trump emergency tariff orders, racing to recover import duties

Costco filed a federal lawsuit in the U.S. Court of International Trade, challenging President Donald Trump’s emergency tariff orders and seeking refunds of duties paid, racing to preserve its right to recover import charges before liquidation deadlines.

  • Who: Costco Wholesale Corporation.
  • What: Federal suit in the U.S. Court of International Trade challenging Trump emergency tariff orders and seeking repayment.
  • Why: Costco contends the emergency-powers statute does not authorize the president to impose or raise tariffs.
  • Urgency: December 15 liquidation deadline could lock in duties and bar recovery.

Overview

Issaquah, Washington (Times Media Service) — Costco Wholesale Corporation has filed suit in the U.S. Court of International Trade arguing that President Donald Trump’s emergency tariff orders are unconstitutional. The company seeks a declaration the orders are invalid and refund of duties it already paid.

Why Costco filed: the central legal claim

Costco says it paid substantial duties this year under the emergency tariff orders and now faces a statutory rule that could bar recovery. The retailer’s legal theory is straightforward: the emergency-powers statute President Trump invoked, in Costco’s view, does not authorize the president to impose or raise tariffs. If the statute does not authorize tariffs, Costco argues, the orders were invalid from the outset.

Costco asks the court to declare the tariff orders invalid and to bar Customs from applying them to future Costco shipments, while ordering refunds of duties already paid.

Reporting and legal background for the filing are available from Fox Business.

The December 15 deadline and why it matters

The case is urgent because of a customs process called liquidation. On or after December 15, U.S. Customs will begin finalizing duty amounts for imported shipments. Once an entry is liquidated, the duty amount is typically locked in and importers generally lose the chance to challenge or recover those charges.

Costco says one of its import entries already has been liquidated and many others approach that cutoff, prompting the immediate filing. If Costco does not obtain timely relief, it risks being unable to recover duties on goods imported throughout the year — the primary financial driver behind the suit.

What Costco seeks from the court

  • Declaratory relief: A court declaration that the tariff orders are invalid because the emergency-powers statute does not authorize tariffs.
  • Injunctive relief: An order preventing U.S. Customs and Border Protection from applying the tariffs to Costco’s future shipments.
  • Monetary relief: A requirement that the government refund duties Costco has already paid under the emergency-tariff program.

Broader context: similar cases and industry impact

Costco joins other importers contesting the legality of the emergency tariff actions. Plaintiffs include Learning Resources, Inc.; V.O.S. Selections, Inc.; apparel firms; auto parts suppliers; and consumer-goods distributors. Some importers have obtained favorable rulings, but those decisions do not automatically entitle other companies to refunds unless they bring timely, entry-specific cases before liquidation.

Retailers argue higher duties have raised costs, squeezed margins, disrupted supply chains, and in many cases forced higher prices for customers. For a high-volume importer like Costco, the cumulative duties can meaningfully affect pricing, inventory choices, and supplier relationships.

Supreme Court review and what might happen next

A pending Supreme Court decision on whether the emergency-powers law permits tariffs could reshape Costco’s case. If the Court rules the law does not permit tariffs, many importers may be eligible for refunds — but only if they filed timely suits tied to liquidation timelines. If the Supreme Court sides with the government, importers may face greater obstacles to recovery.

Because Costco filed in the Court of International Trade, it is seeking a judgment that applies to its own entries before liquidation makes those duties final. The interplay of the Supreme Court’s timing and the December 15 liquidation deadline will be decisive.

Implications

Economic: Victory for Costco and others could lower import costs for large retailers and ease price pressures on consumer goods worldwide. Conversely, final liquidations could lock in higher costs that affect prices and supply chains.

Political: The litigation highlights limits on executive power over trade. A ruling that the emergency statute cannot be used to impose tariffs would constrain presidential authority on trade policy and influence future administrations’ options.

Social and cultural: Changes to duty costs affect household budgets and daily shopping habits. The case underscores how national trade policy decisions ripple into ordinary consumer experiences.

Practical takeaways for importers

  • Review import entries and liquidation timelines immediately.
  • Consider filing entry-specific suits to preserve refund rights before liquidation.
  • Monitor the Supreme Court ruling and legal developments to guide next steps.
