There’s a comforting theory floating around Washington and Detroit alike: if a Chinese automaker just built its cars in Ohio or Alabama instead of Shenzhen, most of the political heat around Chinese EVs would evaporate. Tariffs are a geography problem, and geography can be fixed with a ribbon-cutting ceremony. That theory works fine for tariffs. It falls apart completely for the one federal rule that already decides whether a Chinese-linked car can be sold here at all.
What The Rule Actually Bans
That rule has been on the books since January 2025, when the Commerce Department’s Bureau of Industry and Security finalized its Connected Vehicles rule, built on national-security authority the government has renewed annually since 2019. It took effect two months later. The rule targets two systems: Vehicle Connectivity Systems, which cover cellular, Wi-Fi, Bluetooth, and satellite hardware and software, and Automated Driving System software, the code that pilots a Level 3-and-up self-driving vehicle. Software tied to China or Russia gets phased out starting with model year 2027. Hardware follows with model year 2030.
Ownership, Not Geography
Here’s the part that gets lost every time this debate turns into a conversation about factories. One of the rule’s four prohibitions has nothing to do with where a chip was soldered or a line of code was written. If the company selling the car is itself owned by, controlled by, or subject to the direction of the Chinese or Russian government, it cannot sell a connected vehicle in the United States, regardless of whether the hardware or software inside has any foreign-adversary content whatsoever. Commerce wrote that clause specifically because a Chinese state-linked automaker with an all-American parts bin still answers to Beijing first.
It gets more specific still. The rule defines a “connected vehicle manufacturer” as anyone who assembles completed connected vehicles in the United States for domestic sale, imports them for sale here, or even just bolts self-driving software onto an otherwise finished car for the U.S. market. Commerce added that last category deliberately, over industry objections, precisely so a company couldn’t dodge the rule by outsourcing final assembly. Building the plant in Georgia doesn’t exempt a manufacturer from this regulation; it just makes that company a “connected vehicle manufacturer” under a different paragraph of the same rule. If the parent company is Chinese state-linked, a U.S. street address on the factory doesn’t change who’s legally still selling the car.
Commerce isn’t waiting for a hypothetical to test this. The Auto Wire has reported that the agency already used this narrower ownership authority to bar Polestar, the Geely-linked EV brand, from continuing U.S. sales after the 2026 model year. That’s the same enforcement lever described above, deployed a full year before Congress ever touched the subject.
Where The Confusion Comes From
The build-it-here instinct isn’t irrational. It comes from watching a genuinely different fight play out next door. Tariffs under Section 232 and Section 301 really are keyed to where value gets added to a vehicle, which is exactly why Chinese automakers have spent the past two years fighting European tariff battles and scouting Mexican assembly sites eligible for USMCA treatment. Commerce’s own rulemaking record flags that Mexican strategy directly, warning that Chinese investment in Mexican plants creates a backdoor into the U.S. market that the connectivity rule is designed to close no matter which side of the border the welding happens on. That pressure hasn’t eased, either: Chinese automakers are also sitting on brutal overcapacity at home, exactly the kind of squeeze that pushes a manufacturer to chase assembly deals anywhere it can find them.
The Compliance Machinery
None of this makes the rule absolute. Manufacturers can keep selling otherwise-banned hardware or software if they secure a general or specific authorization from BIS, or if the code in question was written before March 17, 2026, a one-year legacy carve-out added after suppliers warned that auditing existing software libraries for Chinese authorship was nearly impossible. Everyone else has to file an annual Declaration of Conformity, backed by a bill of materials listing every hardware and software component in the connectivity stack, a compliance document the auto industry had never been asked to produce before this rule existed. And the regulation only covers passenger vehicles under 10,001 pounds for now; Commerce has already signaled a second rulemaking is coming for commercial trucks and buses, where it says the same risk exists but the supply chains are too tangled to regulate on the same timeline.
Two Different Tools, Two Different Tests
It’s worth separating these two policy tools clearly, because coverage of this fight constantly conflates them. A tariff is a toll booth: pay it, or build somewhere the toll doesn’t apply, and the car gets through. The Commerce connectivity rule is closer to a background check at the door. It doesn’t care how the car got built. It cares who’s vouching for it. A Chinese state-linked automaker can satisfy every domestic-content requirement in existence and still fail this test, because the test was never about content. It was about control.
That distinction matters more now, not less, because Congress is currently weighing the Connected Vehicle Security Act, which would push the ownership logic even further by banning any vehicle tied to a Chinese, Russian, Iranian, or North Korean company outright, regardless of what connectivity hardware is or isn’t inside it. The 2025 rule was written to be surgical, targeting a specific, provable technical risk. The pending bill drops the scalpel entirely. But both share the premise the factory-relocation theory keeps missing: in this fight, the paperwork follows the ownership structure, not the assembly line.
So when the next Chinese automaker announces a U.S. assembly plant, and at the rate BYD, Chery, and others are circling North America, one eventually will, resist the urge to read it as a regulatory workaround. A factory address can satisfy a tariff schedule. It cannot satisfy a national-security finding about who ultimately answers to Beijing. Skip the zip code. Look at the cap table.
Should Chinese automakers be allowed to sell here if they build plants here? Sound off in the comments.
