According to the filing, the defendants include the government of the United States, the border and customs agency (CBP), and its current commissioner, Rodney Scott.
But getting a refund is not automatic just because the Supreme Court invalidated the tariffs. Importers who paid them have to take separate legal action to force the government to return the cash. Rivian's lawyers wrote in the complaint: "Although the Supreme Court invalidated the tariffs, this separate action remains necessary because importers that have paid IEEPA tariffs, including Plaintiffs, are not guaranteed a refund of amounts previously paid based on the Supreme Court's decision."
Rivian requests the court to order a refund plus interest and cover all related court costs.

According to CBP, more than $121 billion in both "potential and certified refunds have been accepted for processing."
Rivian also faced real-world costs from the tariffs on its vehicles. In a Reuters interview last year after the tariffs took effect, CEO RJ Scaringe said he anticipated a cost increase of "a couple of thousand dollars" per vehicle. He stated that by late 2025, the company had reduced the effect to just "low hundreds of dollars" per vehicle. Rivian recently raised roughly $1.3 billion through a share sale, boosting its cash reserves as it scales production and awaits refunds.
The $71 billion already paid out represents only a portion of the total $121 billion in accepted claims, indicating that many importers are still awaiting their refunds. Rivian's legal action is part of a larger wave of lawsuits from companies seeking to recover funds after the high court's ruling. Scaling production of the R2 SUV is critical for Rivian's growth, and the tariff refund would provide additional financial flexibility. The company's cash position, bolstered by the recent share sale of $1.3 billion, gives it some runway while it pursues the refund through the courts.
Rivian is at a tricky moment. Meanwhile, the company is investing heavily in autonomous vehicle development, with profitability unlikely before 2028.
The tariff refund, if it comes, would help. Rivian elaborated on the impact in a document submitted to regulators during early 2025, saying: "the resulting environment of retaliatory trade or other practices or additional trade restrictions or barriers has harmed, and could continue to harm, our ability to obtain necessary raw materials, components and equipment and could harm our ability to sell our products and services at prices customers are willing to pay."
Rivian's lawsuit is a reminder that even after a Supreme Court victory, companies often have to fight for their refunds. Rivian seeks assurance that it will receive its full refund - the correct amount - from the government.
