US Tariff Refund Lawsuits: L’Oreal, Dyson Among 1,400 Companies Seeking Repayment After Supreme Court Ruling

A fresh wave of legal action has begun in the United States after the US Supreme Court struck down key tariffs imposed under former President Donald Trump’s emergency trade powers. Major global brands are now moving to recover duties they paid under those measures.

Supreme Court Ruling Opens Door to Refund Claims​

L'Oreal, Dyson, and Bausch + Lomb have filed lawsuits seeking refunds on tariffs paid under the International Emergency Economic Powers Act.

The complaints were submitted on Monday before the United States Court of International Trade. The filings follow a 6 to 3 ruling by the Supreme Court of the United States, which found that former President Donald Trump exceeded his authority by using the International Emergency Economic Powers Act to impose tariffs on imported goods.

The decision does not automatically trigger repayments but allows companies to pursue claims through the trade court.

Over 1,400 Importers Join Legal Push​

The latest filings add to a growing list of corporate plaintiffs. More than 1,400 importers have already taken legal action to recover tariff payments.

L’Oreal’s complaint was filed by its Travel Retail Americas division, which manages beauty sales in duty free and travel outlets. Court documents show that the companies involved in the latest suits acted as the importer of record for goods affected by the tariffs. L’Oreal has not disclosed the amount it is seeking.

Additional complaints this week were lodged by FedEx and skincare brand Sol de Janeiro. Court records also list Costco and Goodyear among the companies pursuing legal remedies.

$175 Billion in Tariff Collections Under Review​

Economists at the Penn Wharton Budget Model estimate that as much as $175 billion in tariff collections could be subject to refunds.

However, the lower trade court must still determine how repayments would be structured. According to trade lawyers, the process could take months and potentially extend for years.

Defendants and Next Legal Steps​

As in other related cases, the defendants include US Customs and Border Protection, its commissioner Rodney Scott, and the United States government.

Neither the White House nor Customs and Border Protection immediately responded to requests for comment on the lawsuits.

For now, the Supreme Court ruling has cleared a legal path but has not resolved the financial outcome. Corporations are continuing to file claims, the trade court is set to examine repayment mechanisms, and billions of dollars in collected duties remain under legal scrutiny as the next phase of litigation unfolds.
