China reportedly slows germanium and quartz exports to Taiwan, threatening optical and robotics supply chains
↗
China is reportedly slowing exports of germanium and quartz-based materials to Taiwan, creating supply constraints for semiconductor, optical, and robotics industries.
Engineers building optical interconnects, semiconductor equipment, or robotics motors may face longer lead times and supply uncertainty. The selective delays, applied through China's export-control regime, let authorities review each shipment's end user, so even non-military buyers can be affected. Companies relying on Chinese germanium or quartz should assess alternative suppliers.

China controls about 63% of global germanium supply, giving it leverage over optical and semiconductor supply chains.
The export-control regime requires exporters to disclose customer and intended use, allowing selective delays rather than a blanket ban.
Germanium is critical for silicon photonics photodetectors and optical fiber, while quartz and magnets affect other industries.
