Costco Wholesale has sued the Trump administration, asking the Court of International Trade to consider all tariffs collected under the International Emergency Economic Powers Act unlawful.
The company said in a filing Friday that it is seeking a “full refund” of all duties under the act paid as a result of President Donald Trump's executive order that imposed what he called "reciprocal" tariffs.
In oral arguments in early November, justices appeared skeptical about the government's case to let them continue.
Trump became the first president ever to use the IEEPA law to impose import duties.
Lower courts earlier ruled against the administration's use of the law but kept the tariffs in place while the case was argued.
Through the end of October, the government had collected $205 billion in tariffs.
With Friday's lawsuit, Costco becomes the latest major company to seek tariff refunds through the courts. »
