China Suspends Helium Exports Amid Middle East Tensions, Threatening Chip Supply Chains

China suspended helium exports with immediate effect on Friday, a move aimed at safeguarding its domestic supply as renewed geopolitical tensions in the Middle East threaten the global market for the gas, which is essential for manufacturing semiconductors.

Geopolitical Risks Drive Decision

The export halt comes as escalating conflict involving Iran raises fresh concerns over the stability of global helium supplies, according to a report from Investing.com. The move is designed to insulate China from potential shortages, which affected manufacturers globally, including in China, earlier this year.

China is highly vulnerable to international supply disruptions, as it imports approximately 85% of the helium it consumes. Qatar, one of the world's largest helium producers, has historically supplied more than half of China's imports. Previous disruptions in the Gulf region have highlighted the fragility of this critical supply chain.

Implications for the Semiconductor Industry

Helium is an irreplaceable component in semiconductor fabrication, and any sustained disruption could impact chip production worldwide. The inert gas cannot be synthetically produced on an industrial scale and is primarily extracted from natural gas fields.

In chip manufacturing, helium is used for a wide range of sensitive processes, including:

• Wafer cooling
• Plasma etching and deposition
• Lithography support
• Leak detection in equipment

A Pattern of Strategic Export Controls

This suspension is consistent with Beijing's broader strategy of using export controls to manage strategic resources during periods of market stress or geopolitical uncertainty. In the past, China has imposed similar curbs on shipments of other industrial commodities, such as fuel, fertilizers, and sulphuric acid, to prioritize its domestic market.
