The Polestar 3 rolls off a line in Charleston, South Carolina, the same plant complex that builds the Volvo EX90. On Thursday the Commerce Department’s Bureau of Industry and Security told Polestar it cannot sell that car, or any other new model-year 2027 vehicle, in the United States. The reason has nothing to do with where the car is assembled.
BIS ruled that majority owner Geely, a Chinese company, gives Polestar a “sufficient nexus” to China under the Connected Vehicles Rule, the regulation finalized in January 2025 that restricts Chinese-linked software and hardware in connected cars sold to American buyers. Software attestation began in March, the sales prohibition lands on the 2027 model year, and hardware restrictions follow in 2030. The rule reaches the systems that make a car connected at all: telematics, GPS, the cellular link, the driver-assistance stack. The determination turns on ownership and the software-development chain, not the VIN plant code.
Why Polestar and Not Volvo
Volvo is the reason that distinction matters. Volvo Cars is also majority-owned by Geely, also builds in South Carolina, and cleared the identical rule in May. Two brands under the same parent, two cars off the same Charleston complex, one allowed to sell and one shut out. Whatever BIS weighed to separate them, it was not the assembly line.
The difference appears to be remediation, not luck. Volvo won its authorization after a review focused on governance, technology practices, and data security, which is the language of a company that restructured how its software and customer data are handled to put distance between itself and its parent. Polestar’s vehicle software and platform are understood to run more deeply through Geely’s architecture, and its US footprint is far smaller, so it had less built and less to lose by failing. BIS has not explained the split publicly, and neither has Polestar, which leaves every other automaker to reverse-engineer the standard from a one-word outcome.
What It Costs Polestar
13 percent is what Polestar’s Nasdaq-listed stock fell on the news, and the drop says more about confidence than about volume. The United States was never Polestar’s base. Roughly 94 percent of its first-quarter retail sales came from outside the US, and Europe already accounts for close to 80 percent of the total. Losing the American market costs the brand a slice of volume it had mostly failed to win anyway.
The balance sheet is where it stings. Polestar’s first-quarter gross margin had already swung to negative 3.2 percent from positive 10.3 percent a year earlier, the mark of a company burning cash into a price war it cannot win on scale. CEO Michael Lohscheller framed the response as a pivot, telling investors Europe is now the brand’s “largest growth engine” and that the next model, the Polestar 7, will be built there. What the company did not say is whether it will fight the ruling, and that silence is the open question.
Geely has too much in the ground to simply walk away. Polestar’s cars are built at a plant in South Carolina, sold through a service and parts network, and carried by product lines already funded, and an owner that committed all of that rarely abandons a market over a single determination. That leaves three ways to keep fighting. The first is the Volvo path, remediation, since Volvo won its authorization by reworking governance, data handling, and technology practices to satisfy BIS, and nothing stops Polestar from doing the same work to clear a later model year. The second is the courtroom, where the unexplained gap between two Geely brands on identical facts is the kind of disparity an arbitrary-and-capricious challenge is built on, even against the steep deference courts give national-security calls. The third is patience, because a determination made under the current rule is not permanent, and Geely, which spent the last fifteen years buying and patiently rebuilding Volvo and Lotus, is an owner built to wait out a regulatory posture it expects to change. Polestar’s own risk disclosures already flag its response to the denial and the outcome of potential litigation as open issues.
What Happens to the Cars Already Here
Existing owners are the quieter part of the fallout, and the near term is reassuring. Polestar confirmed it will keep selling the US stock of Polestar 3 and Polestar 4 it already has, and that service, warranties, and over-the-air software updates continue on the same terms for cars already on the road. Nobody’s car bricks because of this ruling.
The longer horizon is where the value leaks. A brand that stops selling new cars in a market starts shrinking everything around them, and Polestar’s US service runs largely through Volvo’s retail spaces, a network that contracts when the new-car revenue behind it disappears. Parts availability, loaner fleets, and trained technicians all thin out over a multi-year wind-down. The predictable result lands on resale value, because a used car whose maker has left the market depreciates faster than one whose dealer is still down the street. The 2025 and 2026 Polestars in US driveways just became harder to sell secondhand than they were on Wednesday.
The Bigger List
Polestar is the headline, but it is the narrow case. The Connected Vehicles Rule does not only target Chinese-owned brands; it bans Chinese-developed software from any connected car sold in the country, which is why automakers across the industry have spent 2026 quietly scrubbing Chinese code to certify compliance. Tracing that code is the hard part. Vehicle software layers through suppliers, subcontractors, and joint ventures, many of them in China, and suppliers resist handing over source code they consider proprietary. A German or Japanese brand can fail this test without a single Chinese shareholder.
That is the exposure worth watching. Foreign automakers that built their newest driver-assistance systems on Chinese stacks, the path Audi took with Huawei in China, now have to prove that none of that code rides in the cars they sell here. Inside Geely’s own house, Lotus is the next obvious question and has no answer yet, with Zeekr, smart, and Lynk and Co behind it. The rule has revealed how deeply American automaking is wired into Chinese software, and the bill for untangling it is being written one brand at a time.
The Precedent
Polestar built its flagship in South Carolina and still cannot sell it, and that is the precedent. For two years the industry treated “build it in America” as the answer to Washington’s pressure on Chinese-linked automakers, and a string of plant announcements followed that logic. This ruling says the plant was never the point. Market access in the connected-car era runs on ownership and the software chain, the parts an export-control lawyer reads, not the parts a buyer can see in the window sticker.
The competitor that benefits is the one with no Chinese code to scrub, which is why the early read on the ruling was that it helps Tesla and the US and Korean EV makers most. Tariffs raise the price of selling here. This rule decides whether you are allowed to sell here at all, and it just proved it will draw that line on ownership and source code rather than on the factory floor. The next brand to test it has read this week’s decision very carefully, because BIS handed down the verdict without showing its work.
