Costco sues to block Trump emergency tariff orders, seeks refunds of duties paid
Costco Wholesale filed suit in the U.S. Court of International Trade seeking to declare former President Trump’s emergency tariff orders unlawful and to recover millions in duties paid, arguing the administration exceeded authority under IEEPA and urging emergency relief.
- Legal challenge: Costco asks the court to invalidate the emergency tariff orders and recover duties already paid (Fox Business, KIRO7).
- Deadline pressure: A Dec. 15, 2025 liquidation deadline could bar recovery if entries are finalized (Fox Business).
- Broad implications: The case could affect many importers and supply chains, and ties into recent court rulings and a Supreme Court hearing (KIRO7, Fox Business).
Background on the emergency tariff orders
In early 2025 the administration issued emergency tariff orders imposing steep duties on imports from multiple countries, including China, Mexico and Canada — with some duties reportedly topping 100 percent. The White House framed the moves as responses to national emergencies tied to drug trafficking, border issues and trade imbalances (KIRO7).
Legal theory: IEEPA and the limits Costco asserts
The administration relied on the International Emergency Economic Powers Act (IEEPA) to justify the tariff program. Costco contends IEEPA does not authorize presidents to impose tariffs and that the tariff program exceeded statutory limits. In the alternative, Costco argues that if IEEPA were read to authorize tariffs, that reading would amount to an unlawful delegation of Congress’s tariff-setting power, creating a constitutional defect (KIRO7, Fox Business).
Why the Dec. 15, 2025 deadline matters
Customs “liquidation” finalizes import entries and locks in duties, after which importers lose many remedies to seek refunds. Costco says at least one of its entries was already liquidated and that more will be finalized on or after Dec. 15, 2025, prompting urgent litigation. The company requested Customs delay liquidation; that request was denied on Nov. 18, leaving Costco to seek emergency court relief to pause liquidations (Fox Business, KIRO7).
Prior rulings and the Supreme Court connection
Federal courts have already sided with challengers in related suits. The U.S. Court of International Trade ruled the emergency tariffs unlawful earlier in 2025 and the Federal Circuit affirmed in August. Those rulings, however, did not automatically return money to importers — each business must pursue its own recovery. The U.S. Supreme Court heard consolidated arguments on Nov. 5, 2025; its decision will shape how quickly and easily companies can recover duties if the tariffs are struck down (Fox Business, KIRO7).
What Costco is asking the court to do
In its 17-page complaint Costco seeks multiple forms of relief, including:
- Declare the emergency tariff orders invalid. (Fox Business)
- Block U.S. Customs and Border Protection from applying the tariffs to Costco shipments going forward. (Fox Business)
- Require refunds of all duties Costco paid under the program, plus interest. (KIRO7)
- Suspend upcoming liquidations that could bar recovery of refunds. (KIRO7)
- Permanently prevent Customs from enforcing the challenged tariff codes for Costco imports. (KIRO7)
Costco also plans to file a motion for a preliminary injunction to halt liquidations while the case proceeds (KIRO7).
The wider wave of business litigation
Costco joins numerous companies challenging the emergency tariffs — including toy maker Learning Resources, wine importer V.O.S. Selections and multiple apparel and parts suppliers. Some challengers have already won key rulings; V.O.S. Selections secured wins that reached the Supreme Court. Businesses say the sudden policy shifts and large duties created market chaos, disrupted supply chains and forced firms to absorb unexpected costs (Fox Business).
Implications for Paso Robles, California
Local impacts could be meaningful for Paso Robles, part of California’s Central Coast wine region. Effects include:
- Economic impact: If Costco obtains refunds or blocks tariffs, national price stabilization could lower costs for Paso Robles restaurants, grocers and consumers who shop at warehouse stores (Fox Business, KIRO7).
- Agriculture and wine industry: Imported equipment, parts and packaging for vintners could become less expensive if tariffs are reversed — a relief for small producers with tight margins (Fox Business).
- Retail and consumers: Paso Robles shoppers who depend on bulk buying may face higher shelf prices if tariffs remain; a favorable ruling could help preserve lower prices (KIRO7).
- Jobs and supply chains: Tariff-driven cost spikes can pressure suppliers to cut hours or delay hires; recovering tariffs could free funds back into local supply chains.
- Political and legal stakes: The suit raises separation-of-powers questions local leaders may weigh in trade and governance debates (Fox Business, KIRO7).
Practical note for local businesses
Importers should watch liquidation schedules closely and consult customs counsel. If Customs finalizes entries by Dec. 15, the ability to seek refunds may be narrowed. Businesses that buy through national distributors should track this litigation because it could affect pricing and supplier contracts (Fox Business).
Legal next steps and what to watch
Costco will seek a preliminary injunction to stop liquidations and preserve its ability to recover duties. The Supreme Court’s ruling following the Nov. 5, 2025 arguments will be pivotal in determining whether and how quickly importers can reclaim payments. Other importers pursuing individual claims will monitor outcomes closely for precedent (Fox Business, KIRO7).
“The case could set a precedent for countless businesses impacted by the tariffs,” said analysts — underlining the national and local stakes.
