Tesla begins Optimus robot production audit in China

Tesla ↗ 2.27% dispatched its robotics team to Ningbo, China, on September 16, kicking off a new round of production audits for the Optimus humanoid robot on September 17. The audit is focused on verifying exclusivity and consistency standards for mass production, assisting Chinese supply chain partners with equipment debugging, and migrating manufacturing capabilities from Tesla's U.S. factories to its Chinese supplier base.finance.biggo+2

The move sent shares of China-listed humanoid robot supply chain companies higher, according to BigGo Finance.finance.biggo

Scaling Toward Mass Production

The Ningbo audit arrives at a pivotal moment for the Optimus program. Earlier this month, supply chain reports indicated Tesla had placed an initial batch order for roughly 5,000 Optimus units and set a target of reaching 1,000 units per week by late September, ramping to between 2,000 and 2,500 weekly by year-end. The production target for 2026 stands at around 50,000 units, according to a KuCoin News report citing the audit.optimusk+2

The September supplier audits serve as Tesla's standard gateway for upgrading vendors from provisional status to certified mass-production partners. Ningbo, a manufacturing hub in eastern China's Zhejiang province, is home to several companies in the Optimus component supply chain, spanning actuators, sensors, and power systems.x+1

A Broader Talent and Competition Picture

The audit comes against the backdrop of intensifying competition for both hardware talent and market share in humanoid robotics. On the same day, a report from Electrek's Fred Lambert confirmed that an 11-year Tesla veteran who most recently led Supercharger hardware engineering is leaving the company to join Figure, the AI humanoid robotics startup based in San Jose. The engineer's name has not been publicly disclosed.basenor

Figure has been on an aggressive hiring run targeting Tesla alumni. Previous departures include Zackary Bernholtz, a seven-year Tesla staff technical program manager who joined Figure in June 2025, and Milan Kovac, who led Tesla's Optimus engineering program for nine years before departing that same month.basenor

China's Humanoid Robot Industry Gathers Momentum

The Ningbo audit also underscores the growing role of Chinese manufacturers in the global humanoid robot supply chain. Global humanoid robot shipments surged 272 percent year-over-year in the first half of 2026, reaching 19,100 units, with Chinese vendors accounting for more than 97 percent of those shipments, according to Forbes and Global Times reporting on data from Smart Analytics Global. In the first half of 2026, Chinese government bodies at all levels spent at least $230 million purchasing humanoid robots and related equipment.mezha+2

As Tesla works to bring Optimus to factory-floor scale, the Ningbo audit marks another step in a supply chain buildout that is reshaping both the company's robotics ambitions and China's role in the emerging industry.
