STM Launches China Production on March 23
STMicroelectronics (NYSE: STM) confirmed on March 23, 2026, that it has started volume production and initial deliveries of its STM32 microcontrollers fully manufactured in China. This milestone, achieved through a 15-year partnership with local foundry Huahong, marks a significant strategic pivot to localize the company's supply chain. The first batches of STM32 wafers are now being delivered to customers within China, addressing local market demand directly.
Dual Supply Chain Aims to De-Risk China Operations
The initiative makes STMicroelectronics the first global semiconductor firm to establish a dual supply chain model for microcontrollers. This strategy provides customers in China with a unique choice between locally sourced chips and those produced outside the country, with both options maintaining identical 40nm technology and quality standards. This approach is designed to create a more resilient and reliable supply chain, shortening lead times and reducing exposure to potential international trade frictions.
Bringing STM32 MCUs to mass production in China is a core commitment of ST to its Chinese customers. In collaboration with Huahong, ST is bringing the very same market-leading products to customers with a secure, reliable, and resilient local microcontroller supply chain.

STM32H7 Series Leads Local Production Rollout
The localization program begins with the high-performance STM32H7 series, which is used in industrial systems, smart home devices, and medical applications. STMicroelectronics plans to aggressively expand its local manufacturing capabilities, scheduling the performance-oriented STM32H5 series and the entry-level STM32C5 series for mass production in China by the end of 2026. This phased rollout ensures a steady supply of key components for a broad range of Chinese industries, from consumer electronics to industrial automation.
