A July 28, 2026 report by the law firm Thompson Coburn counted more than 100 putative class actions in at least 30 federal districts against retailers and carriers, including Costco, Amazon, Nike, FedEx, and UPS. The suits claim unjust enrichment and state consumer protection violations, arguing that companies that passed tariffs on to customers should share IEEPA refunds.
- In March 2026, Bloomberg Law counted more than 17 such suits, most against FedEx.
- A motion to dismiss in a lead case against Costco was fully briefed on June 30, 2026, with a ruling pending as of that report.
