China’s helium export ban puts a neglected semiconductor material back in focus
China’s July 10 ban on helium exports has drawn fresh attention to a material that rarely makes semiconductor headlines but remains essential to advanced chipmaking. Helium is used in plasma etching, leak detection, purge processes and thermal management inside fabs, with electronic-grade helium requiring purity as high as 99.9999%. The move comes as the global helium market has tightened sharply in 2025. According to the source material, Qatar’s Ras Laffan industrial hub — a major global helium production center — was hit by attacks that halted output and damaged export capacity, while roughly 200 liquid-helium containers were stranded in the Middle East. Russia has shifted helium exports outside the Eurasian Economic Union to a government licensing regime starting in April 2026, and the US previously sold off its federal helium reserve. China remains heavily dependent on imports. In 2025, the country’s total helium supply was about 5,818 tons, including 4,913 tons of imports and around 905 tons of domestic output, implying external dependence of 84.4%. Against that backdrop, Beijing said the export ban was aimed at securing domestic supply. The episode also highlights China’s slower but ongoing push to produce high-purity helium from LNG boil-off gas, even though local self-sufficiency remains below 20%.
