AUSTIN, Texas — Tesla has taken a concrete step toward mass-producing its Optimus humanoid robot, certifying three long-time Chinese component suppliers as full production partners after an on-site audit in China. The move, paired with fresh orders, signals that the robot's timeline is accelerating from prototype to real manufacturing.
Tesla's robotics team traveled to Ningbo, in Zhejiang province, on September 16 and spent the following day auditing suppliers. The visit moved Tuopu Group, Ningbo Joyson Electronic and Zhejiang Sanhua Intelligent Controls from provisional status to certified mass-production partners.
Proven Automotive Suppliers Step Up
Each firm brings a specialty: Tuopu handles actuators and chassis components, Joyson supplies sensors, and Sanhua builds thermal-management systems. All three already supply parts for Tesla's electric vehicles, where tolerances and volume demands closely mirror what a mass-produced humanoid robot requires.
That existing relationship matters. Sanhua alone previously received a roughly $685 million order for linear actuators tied to Optimus — a volume industry watchers estimated could cover around 180,000 robots once production ramps. Tapping partners that already meet automotive-grade standards lets Tesla skip much of the trial-and-error that slows a first-of-its-kind product.
A Sharp Production Curve
Supply-chain reports tied to this week's audit put Tesla's near-term goal at about 1,000 Optimus units a week by late September, climbing to 2,000 to 2,500 a week by year-end. The audit reportedly came with an initial batch order of roughly 5,000 units.
That pace would add weight to the timeline Tesla has been building toward since May, when it wound down Model S and Model X production at Fremont to convert that floor space into a dedicated Optimus line targeting one million units annually. JPMorgan analysts who toured the plant in August said the conversion took only about four months — a speed Musk has called unprecedented for a facility that size. Tesla is also raising a second, much larger Optimus plant at Gigafactory Texas.
Building the World's Robot Supply Chain
The certification landed well with markets: the Solactive China Humanoid Robotics Index rose about 1.4% on the news, and Bloomberg Intelligence called the audits "a positive commercialization signal" for the humanoid supply chain. As detailed by Teslarati, the orders suggest Tesla is laying the industrial groundwork now rather than waiting.
Commercial sales of Optimus remain targeted for the second half of 2027, but production is expected to begin well before then, feeding Tesla's "Optimus Academy" program that uses early units to gather real-world training data. With a proven supplier base locked in and ambitions stretching toward 15,000 units and beyond, Tesla is turning what was once a stage-demo curiosity into a manufacturing program with real momentum behind it.
