The FCC announced a ban on new imports of foreign-made mobile robots—humanoids and quadrupeds—plus foreign-made power inverters, citing national security and supply chain risks. Stationary robots and models already sold in the U.S. are exempt. China, source of 90% of global humanoid robot shipments last year, faces the biggest impact; the U.S. was its top export market. Since foreign humanoids serve mainly as low-cost R&D platforms rather than industrial tools in the U.S., the ban could slow domestic robotics research and physical AI development, potentially hampering efforts to reshore manufacturing.
