Japanese officials and executives warn that China's export curbs on gallium, germanium, and other chip raw materials threaten global electronics supply chains

Context & Ripple Effects
This warning extends a supply-chain problem already visible after China’s earlier controls: European gallium and germanium prices had nearly doubled over the preceding year in the prior price run-up for the two chip metals. Japan, South Korea, and Taiwan had previously begun assessing their exposure to the restrictions, with Japan’s imports specifically highlighted in that coverage as regional buyers assessed their exposure.
The significance is not simply a minerals trade dispute. It puts a raw-material constraint upstream of electronics production, at a time when export controls are increasingly shaping where and how semiconductor supply chains can operate.
First-order effects
- Japanese electronics and semiconductor supply-chain participants face greater uncertainty over access to gallium, germanium and other covered inputs, complicating purchasing and production planning.
- The prior European price increase indicates that the curbs can translate quickly into higher input costs for buyers outside China, rather than remaining a bilateral policy issue.
Second-order effects
- Chip and electronics manufacturers are likely to intensify qualification of alternative material sources and inventories; such moves shift demand toward non-Chinese producers but do not immediately create comparable supply.
- Governments and industrial firms will face renewed pressure to support domestic or regional processing: the EU had already asked aluminum and zinc companies to examine chip-metal production after the earlier curbs explored producing these materials locally.
Third-order effects
- If repeated controls continue to constrain key inputs, semiconductor resilience strategies will need to cover specialty raw materials as well as fabs and chipmaking tools—an upstream form of export-control substitution.
- The episode reinforces a more fragmented electronics supply chain, in which national control over narrow material chokepoints can affect global production; the pace of diversification remains constrained by the availability of viable alternative supply.
The trend: Export controls are expanding from advanced chips and manufacturing equipment into the specialized materials that underpin electronics supply chains.
