Costco Sues to Block Trump Emergency Tariffs, Seeks Millions in Refunds
Costco filed a federal lawsuit seeking to declare former President Trump’s emergency tariff orders unlawful, halt Customs from applying them to its imports and recover millions in IEEPA-based duties that the company already paid last year.
- Legal challenge: Costco asks the U.S. Court of International Trade to declare the emergency tariff orders invalid and block U.S. Customs and Border Protection from applying them to its shipments (Fox Business; KIRO7).
- Urgency: Customs plans liquidation on or after Dec. 15, which could lock in duties and limit recovery options (Fox Business).
- Constitutional claim: Costco contends IEEPA does not authorize tariffs and that using it for tariffs unlawfully shifts Congress’s tariff power to the executive (KIRO7; Fox Business).
Overview of the Lawsuit
What Costco filed: The retailer submitted a 17‑page complaint in the U.S. Court of International Trade asking the court to:
- Declare the emergency tariff orders unlawful;
- Block U.S. Customs and Border Protection from applying the tariffs to Costco’s imports;
- Suspend imminent liquidations that would lock duty amounts;
- Order refunds with interest for all IEEPA-based tariffs Costco paid;
- Permanently bar enforcement of the challenged tariff codes against Costco (Fox Business; KIRO7).
Background: The Emergency Tariffs and Their Reach
In 2024 the administration declared national emergencies tied to drug trafficking, border activity and trade deficits, invoking the International Emergency Economic Powers Act (IEEPA) to impose new duties on many imports from countries including China, Mexico and Canada. Some duties reportedly exceeded 100%, with rare rates up to 125% on certain Chinese goods (Fox Business).
The orders were amended, raised or temporarily suspended multiple times in early 2024, creating instability for supply chains and importers, industry groups say (KIRO7).
Costco’s Legal Arguments
Primary claims: Costco argues that (1) IEEPA does not authorize the president to impose tariffs, and (2) interpreting IEEPA to allow tariffs would unconstitutionally transfer Congress’s exclusive power to set tariffs to the executive branch (KIRO7; Fox Business).
“Costco insists it must be allowed to press its own claims before liquidations make recovery impossible,” the complaint emphasizes, noting one entry already finalized and many more subject to imminent liquidation (KIRO7).
Procedural Steps and Immediate Relief Sought
Costco requested that Customs delay liquidation, but Customs denied that request on Nov. 18. In response, Costco filed suit immediately and plans to move for a preliminary injunction to pause liquidations while the case proceeds (KIRO7).
Broader Legal Context
Costco joins other importers challenging the emergency tariff orders, including Learning Resources, Inc. and V.O.S. Selections, Inc., the latter of which won major rulings in lower courts. The issue reached the U.S. Supreme Court with consolidated arguments on Nov. 5; a decision expected soon could determine whether IEEPA may be used to impose tariffs nationwide (Fox Business; KIRO7).
Important procedural note: Even if the Supreme Court deems the orders unlawful, individual importers must still win their own refund claims; liquidation can foreclose those claims.
Implications for the Inland Empire
Economic impact: As a major retailer serving Inland Empire residents, Costco’s success could reduce price pressure on imported goods sold at local warehouses. If tariffs remain and duties aren’t recoverable, higher costs could pass to consumers (Fox Business).
Logistics and distribution: The Inland Empire’s warehouses, trucking firms and distribution centers could see lower long‑term cost uncertainty if tariffs are rolled back or refunds are ordered, stabilizing shipping patterns (KIRO7).
Political and social effects: Local leaders and voters may react to any ruling that narrows presidential tariff powers. Workers in warehousing and retail, small suppliers and household budgets could be affected by changes in import costs and retail pricing.
Practical Advice for Residents and Businesses
- Shoppers: Watch for price or promotion changes at local Costco warehouses if refunds or injunctions are ordered.
- Local businesses: Importers and distributors should monitor the court docket and consult customs counsel quickly—the Dec. 15 liquidation schedule creates urgency (KIRO7).
What’s Next
Costco will file a motion for a preliminary injunction to pause liquidations while the lawsuit proceeds. The U.S. Supreme Court’s impending decision in related cases will also shape whether IEEPA can sustain tariffs nationwide and how refund claims proceed (Fox Business; KIRO7).
Watchpoints: Inland Empire residents and businesses should follow both the district court docket and the Supreme Court outcome for signals about future prices, trade rules and local labor market effects.
