US Bans New Chinese Humanoid Robot Imports, Citing Backdoors and National Security

The United States moved decisively on Tuesday to wall off its robotics market from Chinese competition, with the Federal Communications Commission issuing rules that ban the import of new foreign-made humanoid robots and quadruped robot dogs, along with connected power inverters used to link renewable energy systems to data center grids. The action represents the most sweeping US restriction yet on the physical embodiment of AI, extending the ongoing technology trade war from semiconductors and software into walking machines.

Backdoors at MIT, Princeton, and Carnegie Mellon

The FCC’s action was triggered in part by documented security vulnerabilities discovered in hardware already deployed at leading US research institutions. Security researchers found a Bluetooth Low Energy exploit in Unitree quadrupeds and humanoids that yields root-level, device-wide access — and crucially, is wormable, meaning it can spread autonomously from one robot to another across a network without human intervention. Unitree hardware was confirmed to be operational at MIT, Princeton, and Carnegie Mellon University at the time of disclosure.

FCC Chairperson Brendan Carr framed the restrictions in terms of protecting “America’s critical supply chains,” an argument that has become the standard justification for the administration’s escalating technology restrictions. Beyond the confirmed Unitree backdoors, the agency cited broader concerns: humanoid robots equipped with cameras, microphones, and advanced sensors are inherently dual-use surveillance tools that can map sensitive facilities, capture conversations, and exfiltrate data to foreign servers.

Power inverters were swept into the ban for related reasons. As AI data centers increasingly integrate on-site renewable energy and battery storage, the inverters that manage those connections have become critical infrastructure chokepoints — and Chinese-made inverters have been found to contain undisclosed remote-access capabilities in multiple prior incidents.

China’s Dominant Position

The scope of the impact is substantial. China controls approximately 85% of the global market for humanoid robots, a dominance built on years of aggressive government subsidies, a vertically integrated supply chain, and a manufacturing ecosystem that allows Chinese firms to ship competitive hardware at prices US rivals simply cannot match. Morgan Stanley analysts project China’s humanoid market alone could reach $15 billion by 2030.

Two Chinese firms — Unitree Robotics and AGIBOT — each shipped more than 5,000 humanoid units globally in 2025, the year humanoid robots first achieved meaningful commercial volumes. In the same period, Tesla’s Optimus program and Figure AI, the two best-funded US humanoid developers, each shipped a few hundred units or fewer. The gap in production scale is stark.

The ban applies only to “new versions” of imported products — robots and inverters that have not yet cleared the FCC’s equipment authorization process. Existing devices already owned by US customers and models that secured authorization prior to Tuesday’s publication remain unaffected. Retailers may continue selling, importing, and marketing those already-cleared models indefinitely.

Supply Chain Entanglement

The restrictions create immediate complications for US companies that have built development pipelines on Chinese robotics hardware. Nvidia’s humanoid robot reference design uses Unitree’s chassis as its foundation, a detail that illustrates how deeply Chinese hardware has penetrated US research and prototyping workflows. Developers who have been using Unitree quadrupeds or humanoids as platforms for training AI locomotion models will need to find alternative hardware for next-generation work.

The ban also threatens nascent technology collaboration between US and Chinese robotics firms, several of which had begun exploring component-level partnerships. Those discussions are now frozen.

Geopolitical Timing

The announcement arrives less than two months before a scheduled summit between President Trump and Chinese President Xi Jinping in September — a meeting that had raised hopes in some corners of the industry for a partial thaw in technology trade tensions. Instead, Tuesday’s action signals that the administration intends to use the lead-up to that summit as a period of maximum pressure rather than diplomatic restraint.

Analysts were quick to note the asymmetry of the ban’s effects. Restricting Chinese robots from the US market will protect nascent domestic robotics firms from price competition and buy them time to scale, but the restrictions “will not materially slow China’s overall humanoid development,” as one market analyst put it. China’s domestic demand for humanoid robots is growing rapidly, and Chinese firms will continue selling into the vastly larger global market outside the United States.

The Broader Pattern

The FCC’s robot ban fits a recognizable pattern: a US government agency identifies a specific Chinese technology category, documents a security risk — in this case, actual exploited backdoors — and moves to exclude that category from the US market before Chinese firms can achieve the kind of embedded, lock-in position that makes later restrictions politically and practically costly.

The same playbook was applied to Huawei in telecommunications, DJI in consumer drones, and a succession of Chinese chipmakers in advanced semiconductors. Each ban was initially framed as narrowly scoped and purely security-motivated; each expanded over time as the underlying strategic logic — limiting Chinese presence in critical technology infrastructure — proved more durable than the specific security justification that launched it.

For the robotics industry, the question is whether the ban accelerates domestic US investment in humanoid development or simply raises costs and slows adoption as American companies lose access to affordable hardware for prototyping and research. The answer will depend significantly on how quickly Figure AI, Tesla, and a cohort of well-funded US robotics startups can close the production gap with their Chinese counterparts — a gap that, as of today, remains large.
