The Trump administration has started the process of refunding up to $166 billion in tariffs after the US Supreme Court ruled that the emergency tariff regime was unlawful.

Starting April 20, companies can file claims through the new CBP refund system. More than 330,000 importers across 53 million shipments may be eligible, and as of April 9, over 56,000 importers had already completed the steps tied to roughly $127 billion in claims.
The core ruling was simple: tariffs of that kind can only be imposed by Congress, which forced the rollback of the previous framework. Reuters also reported that refunds are expected to go directly to the companies that originally paid the duties, with interest where applicable.
The process is massive and likely to be messy, but the money is now officially moving into the claims stage.
