Nexperia’s Chinese subsidiary has begun producing its own chips, Reuters reports, signaling a move toward independence from its Dutch parent amid a dispute that has unsettled global automakers’ supply chains. 

According to a post on its Chinese social media account, Nexperia China is now manufacturing several chip types previously handled by the parent company, using 12-inch wafers—a size Nexperia Europe cannot produce. These small-batch 12-inch bipolar discrete devices are not simply scaled-up versions of existing 8-inch products; they were fully redesigned on an independently developed 12-inch platform, with optimized chip architecture, process integration, and manufacturing workflow. 

Compared with traditional 8-inch wafers, the new 12-inch devices can produce nearly twice as many chips per wafer, improving production efficiency, material utilization, and lowering unit costs. 

 The tension between Nexperia Europe, its owner Wingtech, and the Chinese unit dates to October 2025, following a Dutch government move to block wafer production transfers to China. Before the intervention, wafers were made in Europe and packaged in China. Afterward, Nexperia China declared independence, while Nexperia Europe halted wafer shipments, citing nonpayment. 

 Nexperia controls roughly 40% of the global transistor and diode market, with its discrete chips used not only in automotive applications but also in consumer electronics, PC power supplies, motherboards, and chargers. Analysts estimate that China accounts for 50–75% of Nexperia’s global output, meaning sustained disruptions could reverberate across multiple industries.

Impact of Nexperia China’s 12-Inch Wafer Production on the Electronics Supply Chain 

 Nexperia China’s move to produce its own 12-inch wafer chips marks a significant shift in the global discrete semiconductor supply chain. From a procurement perspective, several key implications arise:

 1. Increased Local Production Autonomy 

By developing a fully independent 12-inch wafer platform, Nexperia China reduces reliance on Nexperia Europe for wafer supply. This decreases vulnerability to cross-border regulatory constraints, but also fragments the historical integrated supply chain. Buyers who previously relied on a unified Nexperia supply may now face variations in product delivery schedules, pricing, and technical specifications between Europe and China. 

 2. Higher Production Efficiency and Potential Cost Advantages 

The 12-inch bipolar discrete devices nearly double the chip output per wafer compared with 8-inch production, improving material utilization and reducing per-unit costs. Procurement teams could see more stable unit pricing and higher availability from China, but must also monitor for initial yield fluctuations as the new platform scales. 

3. Supply Chain Risk Shifts 

While local production mitigates geopolitical and shipping delays from Europe, it introduces concentration risk: analysts estimate China accounts for up to 75% of Nexperia’s global output. Any operational disruption in the Chinese plant—technical, regulatory, or labor-related—could have outsized effects on global supply, particularly for automotive, PC, and consumer electronics components.

 4. Geopolitical and Contractual Considerations 

The split between Nexperia Europe and China highlights that contracts and supply agreements may no longer guarantee seamless global sourcing. Companies must review supply contracts, payment terms, and contingency clauses to account for independent operations in China. 

 Conclusion:

 Nexperia China’s 12-inch wafer initiative has the potential to stabilize and expand chip output, offering procurement teams more flexibility and efficiency. At the same time, it shifts supply chain risk from Europe to China, requiring active monitoring, diversified sourcing, and updated procurement strategies to mitigate potential disruptions across automotive, consumer electronics, and industrial applications.
