Costco Has Sued the U.S. Government — and It Highlights the Bigger Failure of Trump’s Tariff Policy
Costco has filed suit against the U.S. government — specifically U.S. Customs and Border Protection — to preserve its ability to receive a full refund on tariffs it has already paid, should the Supreme Court ultimately rule that President Trump’s tariffs were illegal.
This case is not just about Costco. It is a symptom of the deeper economic damage caused by tariffs and protectionism.
Key Details of the Lawsuit
1. Purpose of the Suit
Filed on November 28, 2025, in the U.S. Court of International Trade, Costco’s lawsuit is not intended to strike down the tariffs directly. Instead, it aims to protect Costco’s right to reclaim the money it paid in tariffs — money that may have been unlawfully collected.
2. The “Liquidation” Deadline
Costco faces a crucial December 15, 2025 deadline for certain import entries to be liquidated (finalized by Customs). Once an entry is liquidated, an importer can permanently lose the right to challenge those charges or receive a refund.
Costco says Customs refused to extend the deadline, leaving the company no choice but to sue immediately to avoid losing millions.
3. Legal Foundation of the Challenge
The lawsuit cites earlier rulings by the Court of International Trade and the Federal Circuit, both of which determined that Trump misused the International Emergency Economic Powers Act (IEEPA).
Those courts concluded the law did not give him the authority to impose the tariffs he enacted.
This core legal issue is now before the Supreme Court.
4. The Supreme Court’s Role
The Supreme Court heard arguments last month and is expected to rule soon on whether the tariffs were illegal. Costco’s lawsuit ensures that if the Court rules against Trump’s authority, Costco will be positioned to receive a refund — potentially tens or hundreds of millions of dollars.
5. Part of a Larger Corporate Pushback
Costco is not alone. Major companies including Revlon, Bumble Bee Foods, and Kawasaki Motors have filed similar suits to preserve their rights to reimbursement. Collectively, these legal actions highlight the widespread financial harm caused by the tariffs.
How Tariffs and Protectionism Damage the Economy
Tariffs Are Taxes on Americans — Not on Foreign Countries
Politicians promote tariffs as “making other countries pay,” but that is unequivocally false.
U.S. businesses pay the tariffs. U.S. consumers pay the higher prices. Tariffs are simply a hidden sales tax.
Tariffs Raise Inflation
Economists across the political spectrum agree: tariffs raise the cost of imported goods, and those costs ripple through supply chains, forcing companies to raise prices.
Trump’s tariffs have contributed significantly to higher costs for:
- food
- electronics
- vehicles
- building materials
- clothing
- household goods
The Costco lawsuit underscores how much corporate America has been forced to absorb — or pass on to consumers.
Protectionism Destroys Jobs Rather Than Creating Them
Tariffs are often sold as “protecting American jobs,” but the historical and empirical record shows:
- Far more jobs rely on inexpensive imported inputs
- Retaliatory tariffs reduce U.S. exports
- Supply chains become strained
- Manufacturing declines instead of growing
Every time the U.S. has leaned into protectionism (Smoot-Hawley in the 1930s, steel tariffs in the 2000s, Trump’s first-term tariffs), jobs were lost and recessions worsened.
Tariffs Undermine Global Confidence in the U.S. Economy
The Costco lawsuit points to a growing crisis:
If companies believe U.S. policy is arbitrary, unpredictable, or politically motivated, they lose confidence in the U.S. market.
This raises borrowing costs, increases volatility, and weakens the dollar — the exact opposite of what a healthy global reserve currency requires.
Protectionism Hurts Small Businesses the Most
Large companies like Costco can file lawsuits and hedge against risk.
Small businesses cannot. They simply face:
- higher costs
- lower profits
- reduced competitiveness
- bankruptcy risk
Protectionism is a tax on the middle class and a subsidy for the politically connected.
Conclusion: Costco’s Case Is a Warning Sign
The Costco lawsuit illustrates a much broader economic truth:
Tariffs and protectionism are not “America First.”
They are inflationary, economically destructive, and legally unstable.
If the Supreme Court rules the tariffs illegal, the U.S. will be forced to face an even harder reality:
The economic damage was unnecessary, self-inflicted, and entirely avoidable.
