Humanoid bottlenecks emerge amid US-China tensions

China's hardware dominance raises supply risks

A new Smart Analytics Global (SAG) report says China dominates the ecosystem of motors and reducers for humanoid robots, with the advantage going beyond individual suppliers. Rising production volumes and ongoing U.S.-China tensions are increasing pressure on suppliers. Persistent tensions, including the FCC's ban on foreign-made humanoid robot imports, could turn that dominance into a critical supply chain problem for Western producers. Linda Sui, founder and analyst at SAG, said the biggest vulnerabilities would emerge in the hardware supply chain, particularly motors, precision reducers, actuators and other critical mechanical components.

Western manufacturers face costly alternatives

Humanoid components are specialist, so replacing an existing supplier would be challenging. Alternatives may require significant redesign, testing and validation. Germany's Schaeffler and Japan's Harmonic Drive Systems provide important non-China alternatives, but their current humanoid volumes remain relatively small. The risks extend to upstream materials and manufacturing processes, including permanent magnets, precision gears and bearings. Western manufacturers may need to diversify suppliers, localize production, or source more components from the U.S., Europe, Japan and other areas, even if alternatives cost more. This would likely boost manufacturing costs in the near term, because alternative supply chains lack the scale, efficiency and integration already established in China. Sui said these costs would have to be accepted to ensure long-term supply stability.

U.S. demand gap and supply chain debate

Jeff Burnstein, president of the Association for Advancing Automation (A3), said the U.S.-China gap is less about manufacturing capability than about the market that makes manufacturing worthwhile. China's supply chain followed a national strategy to lead in robotics, while the U.S. has no equivalent robotics strategy, he said. Restrictions on foreign components assume domestic alternatives will fill the gap, but those suppliers do not yet exist at scale. In response, Burnstein called for more incentives to adopt robots, support for small and medium-sized companies, and more government-funded training programs. A phased-in approach to the import ban would have helped the West establish reliable component sources more effectively, he said. Meanwhile, Lian Ji Su, an analyst at Omdia, said China's dominance partly reflects Chinese robotics vendors' preference for Chinese suppliers. Western developers have established options in Schaeffler, Festo and Harmonic Drive, and Su said scale rather than technology is the bigger hurdle.
