Temu has been hit with a proposed class action lawsuit that alleges the online marketplace reaped “windfall profits” from passing on to consumers the costs of tariff duties that have since been deemed unlawful by the United States Supreme Court.

The 20-page Temu tariff lawsuit claims that the defendant passed its tax burden onto consumers by embedding into product prices its own costs to pay import tariffs imposed by President Donald Trump under the International Emergency Economic Powers Act (IEEPA). The “import charges” assessed by Temu for the illegal tariffs drastically increased the prices of many imported products, the suit stresses.

As of the filing date, Temu, which sources the vast majority of its products from China, has neither refunded consumers nor disclosed, crucially, whether it intends to seek IEEPA tariff refunds from the federal government, the Temu lawsuit says. Per the complaint, the company has also “made no commitment to return any portion of the anticipated tariff refunds” to consumers forced to shoulder Temu’s tariff burdens via increased prices.

Should Temu receive a “windfall” refund of tariff-related import taxes and fees—estimated to be tens or even hundreds of millions of dollars—the company will have been doubly compensated, the case charges, adding that Temu allegedly misrepresented the necessity of price increases while “concealing” its ability to recover tariff-related taxes and fees from the government.

The Temu class action lawsuit is one of the latest class action lawsuits filed following a February 20, 2026 Supreme Court ruling that determined the president did not have authority to levy tariffs under the IEEPA, which the court found to be an overreach of presidential power. Subsequently, the tariffs were struck by an executive order, the Temu lawsuit says.

The case further states that the value of potential IEEPA tariff refunds is not “merely speculative,” given that a “robust” secondary market emerged while the tariffs were in effect, leading “distressed” investors and hedge funds to purchase potential IEEPA tariff claims in exchange for immediate liquidity.

Allowing importers like Temu to retain ill-gotten tariff charges “offends public policy,” and the unconstitutional and unlawful IEEPA tariffs do not benefit consumers “in any way,” the lawsuit charges.

“Even if Defendant does not receive a refund, it is still unfair, oppressive, unscrupulous, and causes substantial injury to consumers to charge consumers the cost of unconstitutional, unlawful IEEPA tariffs that provide no benefit to Plaintiff or other consumers anyway,” the complaint reads.

The Temu tariff class action lawsuit looks to cover all United States residents who purchased products from Temu at any time from February 1, 2025 through February 24, 2026, and were charged prices that included IEEPA tariff costs.
