As businesses prepare to recover $166 billion in tariff refunds, logistics providers including UPS, FedEx and DHL are gearing up to reimburse customers now that the official claims portal is up and running.

When these firms imported international packages into the U.S., they paid the tariffs on behalf of the intended recipient. In turn, the companies required payment upon receipt of the package to complete the delivery.

U.S. Customs and Border Protection (CBP) launched its dedicated refund tool for importers seeking reimbursement for tariffs paid under the International Emergency Economic Powers Act (IEEPA) on Monday. The duties, which included country-specific “reciprocal” tariffs levied last April and the punitive fentanyl-related charges imposed on China, were ruled illegal and invalidated by the Supreme Court in February.

Under the first phase of the Consolidated Administration and Processing of Entries (CAPE) deployment process, the platform will only cover refund requests for IEEPA entries that are unliquidated, as well as entries liquidated by CBP within the last 80 days, starting Jan. 30. This amounts to roughly 63 percent of the 53 million import entries subject to the IEEPA duties.

Once an entry is submitted and accepted, CBP will take roughly 60 to 90 days to issue the refund. In the CAPE portal’s first day of launch Monday, over 55,000 parties submitted claims for more than 4 million imports.

FedEx, which sued the federal government and CBP following the Supreme Court decision to recoup the funds, said it was committed to refunding “on behalf of all customers for whom we served as customs broker.”

The company said it would issue the funds as soon as it receives them from the government agency.

FedEx said it will generate the reports needed to secure the IEEPA refunds, as individual consumers cannot file claims. Only the importer of record (IOR), which handled their own customs paperwork and paid their own fees directly, can request refunds through the CAPE portal.

“We have committed to do that on behalf of all customers for whom we served as customs broker,” said FedEx on its website. “The reports are not useful for customers to act on their own or to estimate individual refund amounts. Our intent is straightforward: if refunds are issued to FedEx, we will issue refunds for IEEPA tariffs paid to the shippers and consumers who originally bore those charges.”

UPS and DHL also said in statements that they will automatically issue refunds through established processes and that most customers would not need to contact the companies directly unless they were the IOR.

Not all monies collected during the period are subject to reimbursement. At UPS, administrative fees incurred for the services of rating and assessing the IEEPA tariffs are nonrefundable.

UPS noted that the fees were “legal and valid” at the time of the charge.

FedEx and DHL did not mention administrative or brokerage fees in their online statements addressing the refund process.

Both FedEx and UPS are facing class-action lawsuits of their own from end consumers, with the former embroiled in a high-profile case related to both the administrative fees.

Miami resident Matthew Reiser filed that complaint in late February after being charged additional fees on a shoe order from online German retailer Tennis Warehouse Europe.

Before FedEx would release his package, Reiser was billed an extra $36, combining the $21 in IEEPA tariff duties alongside $15 in customs brokerage and clearance entry fees.

The lawsuit argues that absent the IEEPA tariff regime, the shipment would have entered the U.S. duty-free, and therefore not subject to either fee.

“FedEx is the only entity with legal standing to seek a refund of duties directly from the government,” said attorneys John Morgan and John Yanchunis of the law firm representing Reiser, Morgan & Morgan, in a statement. “This leaves consumers like our client with no choice but to try to legally compel FedEx to refund them for the tariffs that they were charged—not to mention the ancillary fees FedEx added to process these transactions.”

At least 17 lawsuits had been filed as consumers and businesses seek reimbursement for the duties and the corresponding fees, with 11 of those against FedEx alone.
