Tesla Robot Team Audits Yangtze Delta Suppliers; Multiple Firms Hold Orders

According to industry chain sources, Tesla's humanoid robot team visited Top Group, Sanhua Intelligent Controls, and Junsheng Electronics last week for supplier audits. These companies mainly provide joint modules, actuators, and precision structural parts—core electromechanical components for humanoid robots.

The audit is assessing production line quality and compliance. Sources said the suppliers had already received Tesla humanoid robot orders before the audit, though order volumes vary. Once the audit is passed, production is expected to begin soon.

The visits have drawn wide attention from capital markets, signaling that Tesla is moving its humanoid robot program closer to volume manufacturing. Ningbo and the broader Yangtze River Delta, with their dense automotive and robotics supply chain, remain central to that effort.

Passing the audit would position these suppliers for larger contracts as Tesla scales production. These firms are also important members of Tesla's automotive supply chain, with experience in precision manufacturing.

The development underscores how the region is becoming a key base for humanoid robot components. For Tesla, the checks help ensure quality and capacity before ramping up output. Investors are watching the audit outcome closely. The Paper first reported the supplier visits.
