NextFin News — In the months since new U.S. rules restricted equipment authorization for certain foreign-made humanoid and four-legged robots and their power inverters, a quieter channel has remained open. Engineers and investors from Bay Area startups still fly into Shenzhen, walk the multi-level component markets of Huaqiangbei—the dense electronics trading district in the city’s Futian area—and return with hard-shell cases filled with actuators, motion-control boards, sensors, and power modules. The practice predates the restrictions and continues because the density of suppliers, workshops, and ready inventory in that single commercial cluster has no close equivalent on the American side. Formal import routes for finished machines have narrowed; the informal movement of parts has not.
