- Top global companies are seeking refunds from Trump's contested tariffs.
- The Supreme Court is reviewing the legality of Trump's emergency tariffs.
- Corporations fear there will be no refunds even if SCOTUS strikes down tariffs.
Top global companies want their money back from the Trump administration.
The Supreme Court is in the process of deciding whether Trump's tariffs enacted under an emergency law, the International Emergency Economic Powers Act, are legal. To companies that may have already paid billions in duties over the past year, a ruling against tariffs may not be enough to recoup funds.
Small businesses mainly spearheaded the initial wave of lawsuits against tariffs, but some of the largest global corporations are now filing lawsuits in fear that they may not be refunded should the Supreme Court overturn the duties.
Typically, duties paid to the Customs and Border Protection undergo a process called liquidation within a year of the entry of the goods in question. Once liquidation occurs, the chances of getting any money back become slim — and for many companies, their time is running out.
From Costco to Toyota, here are some of the largest global companies that want their tariffs refunded.
Costco
Costco is seeking a "full refund" of tariffs it paid under the IEEPA, arguing the levies were imposed illegally and could soon become unrecoverable.
In a lawsuit filed with the Court of International Trade in December 2025, Costco's lawyers argued that the law, first enacted in 1977, has never authorized tariffs.
"The text of IEEPA does not use the word 'tariff' or any term of equivalent meaning," the company wrote.
The company also said in the complaint that it filed its own suit because even if the Supreme Court ultimately rules the tariffs unlawful, importers are not guaranteed refunds without separate court judgments. Costco said that its imports could begin entering "liquidation" as early as mid-December, which is a customs process that could permanently close the door on refunds. Customs has already declined to extend that timeline, Costco said in the suit.
Costco did not disclose how much it has paid in duties.
Toyota
Subsidiaries of the Toyota Group, Toyota Tsusho America, Toyota Tsusho Canada, and Toyota Tsusho Nexty Electronics America filed a lawsuit in November 2025 to secure refunds.
"And this action is necessary now because the entries for which Plaintiffs paid tariffs imposed under authority of IEEPA will begin to become liquidated and final as a matter of law by January 31, 2026," the companies wrote in the complaint.
"Plaintiffs seek relief from the impending final liquidations to ensure that their right to a complete refund is not jeopardized," they added.
The auto sector has been among the industries most exposed to Trump's tariffs, which added duties on vehicles as well as on steel and aluminum. In May 2025, Toyota said that the higher import and export rates could cost the company about $1.3 billion over a two-month period.
BYD
BYD's lawsuit marks the first from a Chinese carmaker against Trump's tariffs.
The EV giant filed the suit on February 9 and detailed nine executive orders related to trade that affected the company, including tariffs on cars, auto parts, aluminum, steel, and exports from China.
In the complaint, BYD wrote that it is seeking a refund of "all IEEPA tariffs paid to date" and "all IEEPA tariffs that may be paid in the future."
The company also said that aside from China, its imports into the US from Canada, Germany, Mexico, and Poland were also affected.
The Chinese carmaker does not sell passenger cars in the US, but its business here includes buses, commercial vehicles, batteries, energy storage systems, and solar panels. According to its website, the company's truck plant in Lancaster, California, employs 750 workers.
Goodyear Tire & Rubber
On December 10, 2025, Goodyear Tire & Rubber filed its complaint and request for relief, and detailed how tariffs, especially the ones imposed on China, which changed nearly a dozen times, affected the company.
"Where CBP acts in a ministerial capacity (i.e., without discretion) in imposing a duty, the entry's liquidation cannot be protested," wrote Goodyear in its complaint as to why the company is asking the court to block liquidation.
Goodyear sources a significant portion of its raw materials from Southeast Asia, where the rubber plant is widely commercially grown. According to Goodyear's website, the company's manufacturing facilities are located across 23 countries, including China, the US, Germany, Poland, and Thailand.
Alcoa
Alcoa Corp, one of the world's top producers of aluminum, bauxite, and alumina, filed a complaint for tariff refunds on November 26, 2025.
This case is one of several dozen that were consolidated with AGS Company Automotive Solutions v. United States Customs and Border Protection, which became the lead case regarding IEEPA duty liquidation as of December 2025.
As of June 2025, tariffs on most steel and aluminum imports increased to 50%.
