China halts helium exports amid renewed Middle East conflict

China announced an immediate, temporary ban on helium exports on Friday, citing the resumption of military conflict in the Middle East and the threat of new shortages for the critical gas. This move directly impacts the semiconductor industry, which relies on helium for essential cooling and etching processes in chip manufacturing.

The AI industry, particularly in China, is increasingly dependent on domestic chips for training and running AI models. Helium's role in heat management makes it indispensable for semiconductor production. This export ban is the latest in a series of measures by Beijing to secure domestic supplies of vital materials, following similar actions on fuel, fertilizers, and sulphuric acid.

Despite efforts to boost domestic helium production, China remains heavily reliant on imports, with estimates suggesting it sources over 85% of its helium needs from overseas. Qatar is a significant global producer and a major supplier to China. Chinese companies have also become important intermediaries, importing helium, particularly from Russia, and re-exporting it to markets like Europe. This ban could therefore exacerbate existing global supply constraints.

Helium is a non-manufacturable byproduct of natural gas extraction, meaning its supply is inherently limited and cannot be quickly increased through industrial processes. Its unique properties, such as its use in wafer cooling, plasma etching, and various deposition techniques, underscore its importance in advanced technology manufacturing.
