Businesses are officially able to request tariff refunds, but don’t expect consumers to get their tariff dollars back — the government refunds are only for importers.

Companies can try to pass refunds along to consumers, but "It’s nearly impossible to determine how much individual consumers paid," says Terence Lau, the dean at Syracuse University’s College of Law. He says companies raised prices because of tariffs, but often didn’t necessarily pass on the full cost to consumers. "How much of that price increase do you attribute to tariffs? Companies can’t even answer that question."

FedEx is promising to pass on any refunds it receives to customers. Costco says it will try using them to lower prices. Both are facing class action lawsuits over refunds.
