Costco Challenges Trump Tariffs in Federal Suit, Seeks Refunds Before Dec. 15 Deadline
Costco Wholesale has sued in the U.S. Court of International Trade seeking to void emergency tariff orders, recover millions in duties paid on 2025 imports, and halt Customs from liquidating entries after Dec. 15, a date the company says endangers refund claims.

Why Costco sued now
Costco says it has paid millions in tariff duties on goods imported during 2025 under emergency orders issued by former President Donald Trump. The company filed its complaint after learning that U.S. Customs and Border Protection would begin finalizing — or “liquidating” — its import entries on or after Dec. 15. Once an entry is liquidated, the duty assessment becomes final and importers may lose the administrative window to challenge charges and seek refunds. (Source: Fox Business.)
“Timing is central,” Costco’s filing emphasizes, asking the court both to declare the orders invalid and to stop Customs from applying them while the litigation proceeds.
What Costco is asking the court to do
In its complaint, Costco asks the Court of International Trade to:
- Declare the emergency tariff orders invalid;
- Enjoin Customs from applying the orders to future shipments;
- Require the government to refund duties Costco already paid.
The company argues the emergency-powers statute invoked was not intended to authorize tariff increases and that using it for tariffs stretches presidential authority beyond its legal bounds. (Source: Fox Business.)
Legal background and precedent
Costco’s arguments build on prior federal rulings. Both the U.S. Court of International Trade and the Federal Circuit have previously found that the emergency-powers statute at issue does not authorize imposition of tariffs. Those rulings have eroded the administration’s legal basis for the orders, but experts caution that earlier wins do not automatically produce refunds for all businesses.
Importers often must file individual suits before liquidation to preserve refund claims. Meanwhile, the Supreme Court recently heard arguments in a separate case addressing the same core question — whether the president can use the statute to impose tariffs — and its eventual decision could reshape the legal landscape for Costco and many other litigants.

The December 15 deadline and what liquidation means
Customs’ liquidation process is an administrative step that finalizes an import entry and the duty assessment attached to it. Importers have a window to dispute duties or seek administrative refunds before liquidation becomes final. Costco reports one entry already liquidated, with more nearing the Dec. 15 cutoff — creating the urgency behind its current filing. (Source: Fox Business.)
Costco’s suit amid wider corporate pushback
Costco is among a growing list of companies that have sued to block the emergency orders or recover duties they say were unlawfully collected. Plaintiffs range from small importers to national distributors, including Learning Resources, Inc. and V.O.S. Selections, Inc., the latter of which has won notable rulings. Affected firms span apparel makers, auto parts suppliers, and consumer-goods distributors — all citing sudden costs, supply disruptions, and margin pressure. (Source: Fox Business.)
Economic and operational stakes for retailers
For large, low-margin retailers like Costco, unexpected tariffs can meaningfully affect pricing and margins. Sudden duty increases may force price hikes, compress profits, or be absorbed elsewhere in a business — choices that can affect membership models and price-conscious customers. The lawsuit frames the action as both a legal challenge and a practical step to protect customers and company finances. (Source: Fox Business.)
How court outcomes could affect refunds and policy
If the Court of International Trade rules for Costco before liquidation, Customs could be barred from applying the emergency tariffs to those entries and refunds could follow. Conversely, if the Supreme Court ultimately upholds the emergency orders, individual suits may face higher barriers to refunds. Legal analysts stress that timing will be crucial: pre-liquidation decisions leave wider recovery paths, while late rulings may leave many importers locked out. (Source: Fox Business.)
Implications for the United States
Economic impact: Large refunds or an injunction against the emergency tariff orders could shift costs back to the federal treasury and ease retail inflation pressures; upheld tariffs could push higher input costs through consumer prices.
Political consequences: The case magnifies debates over presidential emergency power, separation of powers, and predictable trade policy — outcomes that could either curb or expand executive authority on tariffs.
Social and cultural effects: Persisting tariffs that stick may reduce household purchasing power; refunds could slow price growth. The dispute also underscores tensions between nationalist trade approaches and free-trade preferences among some business and conservative constituencies.
Practical advice: Importers should review entry records and consider legal action before liquidation; retailers and wholesalers should prepare for short-term pricing uncertainty; consumers should watch for price changes in coming months.
