Export Suspension
China announced an immediate suspension of helium exports on Friday, citing the need to safeguard domestic supplies as renewed fighting in the Middle East, particularly involving Iran, raises the risk of fresh disruptions to the global helium market. Helium is a critical input for semiconductor manufacturing, where it is used to cool equipment and support multiple stages of chip production.
Role of Helium in Semiconductor Production
In semiconductor fabrication, helium is employed for wafer cooling, plasma etching, chemical vapor deposition, atomic layer deposition, lithography support, and leak detection, making its uninterrupted availability vital for chip makers.
China’s Dependence on Imported Helium
China remains heavily reliant on imported helium, with imported supplies accounting for roughly 85% of its consumption, despite exporting a limited surplus to neighboring Asian markets. Qatar, one of the world’s largest helium exporters, has supplied more than half of China’s helium imports in recent years. Earlier this year, attacks linked to the Iran conflict disrupted exports from Gulf producers, underscoring the fragility of the global helium supply chain.
Context of Prior Export Restrictions
The current export suspension follows a series of Chinese restrictions on shipments of strategic materials and industrial commodities designed to prioritize domestic supply during periods of market stress. Earlier curbs have targeted products such as fuel, fertilizers, and sulphuric acid.
Helium Production Constraints
Helium cannot be produced synthetically on an industrial scale and is primarily extracted from natural gas fields with high helium concentrations, limiting the ability to quickly substitute or increase supply in response to geopolitical shocks.
