Tesla’s Optimus program has never lacked ambitious production targets. What has been harder to see is the manufacturing machinery needed to turn those targets into robots.
That may now be starting to change.
Chinese outlet The Paper reported on September 21 that Tesla’s robotics team had begun factory audits at suppliers including Tuopu Group, Sanhua Intelligent Controls and Joyson Electronics. The companies are associated with components such as joint modules, actuators and precision structural parts. An unnamed supply-chain source went further, claiming that the suppliers had already received Tesla humanoid-robot orders and that production could follow once quality and compliance audits were completed.
That is a meaningful claim. It is not yet a confirmed one.
The Audits Have More Support Than the Orders
South China Morning Post separately reported on September 18 that Tesla officials and engineers were auditing Chinese suppliers ahead of an Optimus production ramp. Its report also identified Sanhua, Joyson and Tuopu, citing two corporate executives with business ties to the manufacturers.
The overlap strengthens the case that supplier qualification activity is underway. It does not independently prove that firm Optimus orders have already been placed.
First Financial added an important layer by contacting the suppliers directly. Tuopu said it had not received notice of the reported new audit, but confirmed that Tesla personnel routinely visit its Ningbo operations and that the companies cooperate on linear actuators, rotary actuators and dexterous-hand actuators. Sanhua said it was unaware of the new audit but was working with a major customer on robot joint actuators. Joyson declined to discuss downstream customers because of confidentiality requirements. Tesla did not respond.
So there is a real supply-chain relationship around robotics components. The specific claim that all three companies already hold Optimus orders remains unverified.
Why This Matters More Than Another Optimus Demo
Supplier audits are not mass production, but they are closer to manufacturing evidence than another robot video or production forecast.
Tesla itself has already confirmed the factory side of the story. In its Q2 2026 update filed with the SEC, Tesla said it had decommissioned the Model S and Model X manufacturing lines at Fremont and was installing its first Optimus production lines. Tesla classified Optimus manufacturing in both California and Texas as “Construction” and said initial Fremont builds would be used in its Optimus Academy for training-data collection and further development.
That matters because supplier qualification fits logically with Tesla moving from line construction toward actual production preparation.
But the distinction is important. Auditing a supplier does not tell us how many components have been ordered, whether the supplier has passed qualification, whether serial component production has started, or how many complete Optimus robots Tesla can manufacture.
The Paper also describes the coming robot as Tesla’s third-generation humanoid and its first version intended for mass production. That may prove correct, but the source set reviewed here does not contain an official Tesla V3 unveiling or a confirmed V3 production specification.
The Next Evidence Is Physical
The Optimus manufacturing story is becoming more tangible.
The next proof points should be equally tangible: suppliers confirming orders, completed production audits, serial component output, Tesla showing the production version of the robot, and finished Optimus units coming off the Fremont line.
Until then, the evidence supports a narrower conclusion.
Tesla appears to be moving deeper into supplier qualification and production preparation for Optimus. That is genuine manufacturing progress. It is not yet proof of mass production.
