Rivian is taking the US government to court. They want their tariff money back. It isn’t a small amount.
The electric vehicle manufacturer filed a lawsuit last week against the federal government, the US Customs and Border Protection (CBP), and CBP Commissioner Rodney Scott. The filing, submitted to the US Court of International Trade on Thursday, targets the “Liberation Day” trade policy implemented by former President Donald Trump. The Supreme Court has already struck down these tariffs as unconstitutional, but the refund process is stuck in limbo.
How Rivian is fighting for tariff refunds
Rivian’s legal team is asking the court to declare the import duties collected under the International Emergency Economic Powers Act (IEEPA) as “contrary to law.” They are also demanding a full refund, complete with interest, plus all associated court fees and attorney costs.
The situation started in April 2025. President Trump invoked a national emergency citing persistent trade deficits. He used the IEEPA to slap tariffs on nearly every trading partner. The baseline was 10%. Some countries saw reciprocal rates hit 50%.
For Rivian, this wasn’t abstract policy. It was a direct hit to their bottom line.
The company claims these duties added “hundreds of dollars” to the cost of each vehicle. They disrupted supply chains for raw materials. They hampered Rivian’s ability to price their trucks and SUVs competitively against other makers.
Why the Supreme Court ruling didn’t end the fight
The legal landscape shifted in February. The Supreme Court ruled that the IEEFA does not authorize a president to impose tariffs.
The 1977 statute was designed as a sanctions tool. Its purpose was freezing assets and blocking transactions with specific entities. It said nothing about tariffs, duties, or raising revenue.
That ruling killed the legal basis for the “Liberation Day” tariffs. But it didn’t solve the money trail. The court decision ended the collection of new tariffs. It didn’t explain how existing payments would be returned.
The Supreme Court ended the legal basis for the tariffs, but it did not settle who gets money back or how.
That gap is what Rivian’s suit aims to close. They aren’t just asking for a declaration. They are demanding the government correct any assets “liquidated with the assessment of IEEAP tariffs.”
What is the expected refund amount?
The stakes are high for the automaker. CFO Claire McDonough was clear about the scale of the claim during Rivian’s Q1 2026 Earnings Call in April.
She expects the refund to land in the “tens of millions of dollars.”
It’s a significant sum for any mid-sized EV maker. For Rivian, it’s a matter of survival and competitiveness. The tariffs distorted their cost structure at a critical growth phase. Getting that capital back isn’t just about justice. It’s about staying solvent in a brutal market.
Is Rivian the only company seeking refunds?
No. Rivian is part of a much larger queue.
Reports earlier this month revealed a massive backlog in the refund process. Only about $71 billion in IEEPAT tariff refunds have actually been paid out to businesses.
That number is low. It falls well short of the more than $124 billion in refund applications that CBP told TechCrunch had been accepted for processing.
There is a huge discrepancy between what companies are owed and what they are receiving. The system is clogged. Rivian’s lawsuit highlights the frustration of manufacturers waiting for money that belongs to them.
Rivian declined to comment on the specific lawsuit. But the action speaks for itself. They aren’t waiting for the administrative pipeline to unclog. They are forcing the issue in court.
The question now is how quickly other automakers will follow suit. And whether the government will fight back or cut the losses. The clock is ticking on these refunds. For Rivian, time is money. And they want every cent.
