What happened
China is slowing or restricting shipments of germanium, quartz, and permanent magnets to Taiwan, causing delivery delays and lost orders for Taiwanese manufacturers. China imposed export controls on germanium in 2023 and quartz in late 2024, requiring exporters to disclose end customers and intended use, giving Chinese authorities visibility and control over the supply chain.
Why it matters
Founders and builders sourcing hardware, optics, or robotics components that depend on Taiwanese manufacturing should expect longer lead times and potential order losses as customs delays bite. If your product roadmap assumes stable supply from Taiwan-based fabs or component makers, pressure-test those timelines now and identify alternate sourcing for germanium- and quartz-dependent parts.
Discussion angle
Which parts of your current or planned product stack quietly depend on materials flowing through this chokepoint, and what's the realistic cost of qualifying alternate suppliers before delays hit?
