U.S. Judge Orders Customs To Refund Billions Collected From Illegal Trump Tariffs
A U.S. trade court judge has ordered federal authorities to begin issuing refunds to companies that paid tariffs later ruled illegal by the Supreme Court, a decision that could result in billions of dollars being returned to American importers.
The ruling places immediate pressure on U.S. Customs and Border Protection (CBP) to develop a system for reimbursing businesses that paid duties under a trade policy central to former President Donald Trump’s economic agenda.

Court Orders Refunds With Interest
Judge Richard Eaton of the U.S. Court of International Trade in Manhattan directed the government to begin calculating refunds for importers who paid tariffs that the Supreme Court ruled unlawful last month.
Importers must not only receive the money they paid but also interest on those payments, according to Eaton’s order.
The judge instructed Customs officials to determine the proper value of millions of shipments that entered the United States with tariffs applied. Those shipments must now be recalculated as if the tariffs had never existed, which would trigger automatic refunds.
During a court hearing, Eaton emphasized that issuing such refunds should be within the agency’s capabilities.
“Customs knows how to do this,” he said, noting that the agency regularly processes refunds when companies overpay duties on imported goods.
“They do it every day. They liquidate entries and make refunds,” he added.
Massive Administrative Challenge
Despite the judge’s confidence, Customs officials have warned that the scale of the task is unprecedented.
In court filings, CBP said it may need to review more than 70 million import entries in order to remove the tariffs and calculate refunds.
The agency had previously asked for up to four months to evaluate how it could manage the massive administrative workload.
Officials described the process as far larger than any previous refund effort handled by the agency.
Customs has not publicly commented on the judge’s order.
How the Refund Process Works
When goods enter the United States, importers initially pay an estimated tariff based on the shipment’s value. The final duty amount is typically confirmed about 314 days later in a procedure known as “liquidation.”
Judge Eaton ordered Customs to finalize those entries without applying the disputed tariffs, which would automatically trigger refunds.
To monitor progress, Eaton scheduled a follow-up hearing for Friday, during which the government must provide updates on its refund plan.
The court also indicated that Eaton will serve as the sole judge overseeing tariff refund cases, suggesting the legal disputes could be centralized under his supervision.
Supreme Court Ruling Created Confusion
The refund order follows a Supreme Court decision last month that ruled certain tariffs imposed under the International Emergency Economic Powers Act (IEEPA) were unlawful.
The tariffs were a cornerstone of Trump’s trade strategy and generated more than $130 billion in revenue for the U.S. government.
However, the Supreme Court did not provide clear instructions about how the government should return the funds, leaving agencies uncertain about the next steps.
Judge Eaton’s ruling now attempts to establish a framework for issuing those refunds.
Thousands of Lawsuits Already Filed
The court order arose from a lawsuit filed by Atmus Filtration, a company that manufactures filtration products.
The company said it paid about $11 million in tariffs that were later ruled illegal.
Its lawsuit is one of nearly 2,000 cases filed in the trade court by companies seeking reimbursement for tariffs collected under IEEPA.
Eaton indicated that the court does not want to process thousands of individual lawsuits.
Instead, he urged the government to establish a single system allowing importers to claim refunds more efficiently.
“We want to work out a method by which those importers can make a claim for duties that were unlawfully applied,” the judge said.
Hundreds of Thousands of Businesses Affected
The tariffs impacted more than 300,000 importers, most of which are small and medium-sized businesses.
Many companies say they lack the resources to pursue lengthy legal battles with the government.
As a result, industry groups are urging Customs to implement a simple and inexpensive refund process.
Without a streamlined system, some businesses say they might abandon their claims entirely rather than navigate complicated legal procedures.
“There should be no impediment to CBP issuing refunds,” said George Tuttle, a trade attorney who represents several importers affected by the tariffs.
Government May Challenge the Order
Legal experts say the government could still challenge the scope of the judge’s ruling.
Ryan Majerus, a former senior Commerce Department official who is now a partner at the law firm King & Spalding, said the court’s language appears to support a broad approach.
“The order strongly suggests an across-the-board approach,” Majerus said, meaning importers may be entitled to refunds automatically.
However, he added that federal officials may still ask the court for additional time to manage what he described as a monumental administrative task.
Billions at Stake
If implemented fully, the refunds could amount to tens of billions of dollars, potentially making the case one of the largest trade-related reimbursement efforts in U.S. history.
The outcome could also reshape how future administrations use emergency powers to impose tariffs.
For now, the immediate challenge lies in whether Customs can design a system capable of processing millions of refunds across tens of millions of import records—a task that could take months to complete.
