If you thought the tariff rollout was chaotic, just wait until the refund bonanza gets under way. In a 6-3 decision issued last February, the Supreme Court invalidated the Trump Administration’s interpretation of the International Emergency Economic Powers Act, the 1977 legislation the president used to justify the levies he imposed on countries around the world. However, the high court did not address how companies might seek reimbursement for the $166 billion they paid the U.S. government over the past year—or whether the money should trickle down to customers who paid a tariff-inflated price.

First there’s the simple matter of actually getting the money back. On Monday, U.S. Customs and Border Protection unveiled a portal where companies can file claims to recover the funds, pending a processing period of 60 to 90 days. While that may seem straightforward enough, the process of applying for a refund is a complex administrative hurdle—meanwhile, some early applicants have already reported severe technical difficulties with the portal itself. Hovering over the entire process is the possibility that the president may launch an 11th hour legal challenge to halt payments (many home industry executives privately express disbelief that a refund will truly be issued, despite recent developments).

Then there’s the political question. While many businesses preemptively sued the government to get a refund—and thousands more will put their application into the official portal—others have pointedly not filed refund lawsuits, Apple and Amazon among them. It was, perhaps, a reflection of their leadership’s deep desire not to draw Trump’s ire—in an interview with CNBC on Tuesday, the president said that he’d “remember” companies that exempt themselves from refunds.

“We are currently evaluating whether it makes sense to file for refunds,” says Marco Credendino, founder and CEO of Artemest, the luxury e-tailer of Italian-made luxury goods. “The situation remains highly dynamic, with new tariffs introduced shortly after others are declared invalid or removed. This creates uncertainty not only around eligibility, but also regarding the administrative effort involved, the timeline and the likelihood of recovery.”

Like many companies in the design industry, Artemest absorbed much of the tariff burden rather than passing it on to customers, especially when not-yet-shipped orders became subject to new tariffs. However, in some instances, it raised prices to reflect tariff fluctuations—that approach (as opposed to a broken-out line item on an invoice) likely complicates any effort to pay end consumers back equitably. “Historically, Artemest has applied general import and customs fees in a structured and transparent way, but we have not passed tariffs through to clients in full,” says Credendino. “Any potential refund would therefore need to be assessed carefully. Our priority would be to allocate any recovered funds in a way that supports our clients and maintains price stability over time.”

Businesses that made tariff fees a line item on invoices from the get-go may have an easier time allocating funds for reimbursement going forward. One commercial textile distributor who spoke on the condition of anonymity said they planned to return those line-item funds to customers, but it all depends on when and if the technicalities get sorted on the government side—and whether new tariffs are incoming. The amount of money at stake is not small: That distributor paid $1 million in tariffs.

A handful of executives have told Business of Home on background that they’re exploring ways to return at least some of the refund money to their customers. And while few companies are willing to go on the record to discuss their plans, a couple have attempted to state their intentions, however vague, in public. According to Money magazine, Costco CEO Ron Vachris promised “lower prices and better values,” in an earnings call on March 5, and Home Depot said that the company would be “our customers’ advocate for value” when asked about tariff refunds.

In Costco’s case, passing the refund on to customers may come at the sharp end of a lawsuit—a group of consumers has filed a class action case against the retail giant, looking to claw back some of the higher prices they paid last year. Fear of similar lawsuits may be another wild card in what home executives choose to do—or not do—now that the tariff refund portal is officially open.
