The tariff saga that has defined retail's 2026 is entering an unfamiliar phase: getting money back. And as FedEx detailed this week, the refund mechanics come with a wrinkle that should make every importer read the fine print.

On the company's fiscal Q4 earnings call, EVP and Chief Customer Officer Brie Carere said FedEx will begin passing refunds on now-defunct tariffs back to the customers who originally paid them starting in August, per Supply Chain Dive. The carrier had roughly $800 million in International Emergency Economic Powers Act tariff refunds slated to go back to shippers as of the end of its quarter. Because FedEx served as the importer of record on those shipments, the government's refunds — which it began receiving May 11 — flow to FedEx first, and then back out to customers.

The scale of the reconciliation is the story. FedEx says it is managing more than 20 million entries carrying IEEPA duties across hundreds of thousands of accounts, and it currently can't even produce a clean per-customer refund report because the data "would be incomplete and would not provide an accurate refund estimate or a determination as to who ultimately bore the tariff charges." To untangle it, the carrier plans to launch a portal by July 10 where customers can check whether a refund has landed and what it's worth, with initial disbursements beginning around August 10.

Here's the part worth flagging: FedEx says shippers who opt into "sharing limited shipment and refund data with trusted vendor partners" inside that portal will be prioritized for disbursement. Customers who decline data sharing "will still receive refunds, though on a longer timeline based on available internal resources." Translated: your own money comes back faster if you agree to let it be shared with FedEx's partners. It's a small design choice with large implications — a logistics provider using the leverage of a refund queue to extract data consent.

FedEx isn't alone in the position. UPS is applying for refunds totaling a little under $500 million on 2.5 million eligible entries, CEO Carol Tomé has said, and plans to apply refunds against customers' open invoices before disbursing the remainder 60 to 90 days after receipt. DHL estimates 30 to 90 days to process payments and will issue checks to whichever party originally paid the duty.

For retailers and brands that import through these carriers, this is a working-capital event hiding inside an operations headache. Billions of dollars that came out of merchants' pockets over the past two years are parked at logistics providers and the U.S. Treasury, trickling back on rolling, opaque timelines. Endcap has tracked the tariff story from the permanent end of de minimis to the pass-through pressure showing up in earnings at the likes of Best Buy. The refund wave is the back half of that ledger — and as FedEx's opt-in-for-speed design shows, even getting your own money back now comes with terms. Finance and logistics teams should be reconciling entries, verifying who actually bore each charge, and deciding how they feel about trading data for a faster check.
