Rivian Takes On the U.S. Government to Reclaim Tens of Millions in Unconstitutional Tariffs

Rivian is fighting back. The electric vehicle maker filed suit against the U.S. government Thursday in a bid to recover every dollar it paid under President Trump’s now-invalidated “Liberation Day” tariffs. TechCrunch first reported the move.

The complaint landed in the U.S. Court of International Trade. It names the federal government, Customs and Border Protection, and CBP Commissioner Rodney Scott as defendants. At stake: tens of millions of dollars. And the precedent for how importers recover duties the Supreme Court already deemed unlawful.

But this isn’t just about one company’s ledger. It’s about friction in a refund system that has processed claims totaling more than $121 billion yet still leaves many businesses waiting. TechCrunch noted that CBP told the outlet over $121 billion in potential and certified refunds have been accepted for processing. A Cato Institute analysis put actual payouts at $71 billion, pointing to built-in obstacles.

Rivian wants more than money. The suit seeks a formal declaration that the tariffs were contrary to law. It demands repayment with interest. Court costs too. Its lawyers put the problem plainly. “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.”

Those words come straight from the complaint. They explain why a Supreme Court victory wasn’t enough. The tariffs rested on the International Emergency Economic Powers Act. Trump invoked it for sweeping “Liberation Day” levies. The high court struck them down. Yet refunds didn’t flow automatically.

Rivian’s chief financial officer flagged the exposure months ago. In April Claire McDonough told investors the expected refund would land in the tens of millions. That figure matters now more than ever. The company is preparing to launch its first mass-market SUV, the R2. It aims to deliver 20,000 to 25,000 units by year-end. It raised $1.3 billion in a recent share sale. Every recovered dollar helps fund the push toward profitability, expected perhaps in 2028.

Tariffs hit Rivian early. CEO RJ Scaringe said last year the duties would add a couple of thousand dollars to the cost of each vehicle. The company responded by shifting suppliers. By late 2025 the per-vehicle hit had fallen to the low hundreds. Still, the damage accumulated. A regulatory filing described the broader pain. “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 isn’t alone. Thousands of firms have challenged the same tariff regime. Chinese EV maker BYD sued earlier this year, becoming the first from that country to contest Trump’s use of IEEPA. Automotive World covered that filing. Toyota and others joined the fray. The wave of litigation reveals deep frustration with unilateral trade powers and the slow grind of reimbursement.

CBP has defended its record. The agency points to the sheer volume of refunds already in motion. Yet importers report delays, disputes over amounts, and uncertainty. That uncertainty is exactly what Rivian seeks to eliminate. Its suit asks the court to guarantee repayment of the proper sum. No more guesswork.

The timing feels pointed. Rivian is scaling production at its Illinois plant. It continues to invest heavily in autonomous technology. Profitability remains elusive. Any unexpected cost spike, or any delay in recovering past overpayments, threatens the delicate math behind its survival. And the EV sector as a whole still reels from earlier rounds of tariffs that raised battery and component prices across the board.

Recall how the duties first landed. The Trump administration justified broad import taxes under emergency powers. Critics called the legal theory stretched. The Supreme Court agreed. Its ruling voided the levies. But it left the refund mechanics to lower courts and the agency. Hence this lawsuit. And likely others to follow.

Industry watchers see larger implications. Successful recovery could ease cash pressure on Rivian as it competes with legacy automakers that have deeper reserves and more domestic supply chains. Failure, or even prolonged litigation, might force further price hikes or production cuts. Either outcome will shape investor views on the company’s $RIVN stock, already volatile.

Rivian declined to comment beyond the filing. Government defendants have yet to respond in court. The case will test how quickly the trade court can cut through refund disputes when the underlying policy has been declared unconstitutional.

So far the refund pipeline shows both progress and problems. Billions paid out. Billions more queued. Cato’s analysis suggests procedural hurdles remain. Rivian aims to clear one of them. Its suit could become a template for other automakers and importers still waiting on their money.

The battle underscores a basic tension. Trade policy swings fast. Commerce adjusts slowly. Companies like Rivian, caught in the middle, pay first and litigate later. This time the company refuses to wait quietly. It wants its cash. With interest. And a clear legal statement that the original tariffs never should have applied.

Whether the court delivers that relief quickly will matter not just for Rivian but for the dozens of manufacturers navigating the same thicket of post-ruling claims. The decision could accelerate refunds across sectors. Or it could prolong a bureaucratic slog that already spans years. Either way, the suit marks a new chapter in the long fight over Trump-era trade actions that outlived the administration itself.
