China Bans Helium Exports as Global Supply Crunch Worsens

China has imposed an immediate temporary ban on helium exports, tightening global supply of a gas that is irreplaceable in semiconductor manufacturing, as a cascading crisis triggered by the Middle East conflict and Russian export controls threatens the chip industry. The Ministry of Commerce and the General Administration of Customs jointly issued Announcement No. 29 of 2026 on July 10, invoking China’s Foreign Trade Law to prohibit exports of helium under Customs Commodity Code 2804290010 with no stated expiry date, no country exemptions, and no transition provisions for existing contracts, according to Caixin Global.

Why Helium Matters

Helium is a non-renewable noble gas with a boiling point of -268.9°C — just 4.2 degrees above absolute zero — making it the only substance capable of maintaining the ultra-low temperatures required by superconducting magnets in MRI machines, quantum computing research, and semiconductor fabrication equipment. In chip manufacturing, helium performs multiple critical functions: it cools wafers during plasma etching, serves as a carrier and purge gas in deposition processes, and enables leak detection in vacuum systems. As LawStreet Journal noted, “No other gas combines the right density, thermal conductivity, and chemical inertness to replace it in wafer cooling. When helium is unavailable, the processes that depend on it simply stop.”

The Triple Supply Crisis

China’s export ban is the third in a series of shocks that have progressively degraded global helium availability since early 2026.

The first and most severe disruption came in March 2026, when military attacks on QatarEnergy’s facilities in Ras Laffan Industrial City — part of the US-Israeli war on Iran that began on February 28 — shut three helium plants, cutting approximately 30% of global supply. Qatar had supplied more than half of China’s helium imports.

The second shock arrived in April 2026, when Russia imposed temporary export controls on helium, set to remain in force through the end of 2027. Russia’s Amur Gas Processing Plant, the world’s largest helium facility which opened in 2022, had become a significant global supplier. Moscow reduced Asian supply quotas to 40% of 2025 levels.

China’s own ban, the third shock, closes a critical re-export channel. Chinese companies had been acting as intermediaries, importing Russian helium and re-exporting to Europe and Southeast Asia. The Seoul Economic Daily reported that the ban extends China’s strategic materials control framework — previously applied to rare earths, gallium, germanium, and graphite — to helium for the first time.

China’s Paradoxical Position

China imports 80-90% of its helium, making the export ban an unusual move for a net importer. In 2025, China consumed 5,818 tons of helium, with imports accounting for 84% of total supply, while exporting 445 tons — up 90% year-on-year. The average price of imported tube-trailer helium in China reached 291 yuan ($42.8) per cubic meter in Q2 2026, up 180% year-on-year and 223% from the previous quarter.

The ban addresses a structural vulnerability: Chinese intermediary companies had been re-exporting available helium to overseas buyers at higher prices, a rational commercial response in a tight market, but one that threatened domestic supply for China’s semiconductor and AI industries. Beijing has invested heavily in domestic chip production, partly in response to US export controls on advanced semiconductors, and cannot afford disruptions to fab operations.

Legal Architecture: A Defensive Measure

Announcement No. 29 differs notably from China’s previous export control measures. Unlike the sophisticated licensing regimes for gallium, germanium, and graphite under the Export Control Law, the helium ban invokes only the Foreign Trade Law — a broader statutory instrument for emergency supply management. As LawStreet Journal observed, “There is no licensing process. There are no exemptions. There are no transition provisions for existing contracts.” The announcement is twelve lines long.

This legal structure suggests the primary motivation is defensive supply management rather than strategic export weaponization. However, the absence of an expiry date means the ban could remain in place indefinitely, with any lifting entirely at Beijing’s discretion.

Global Impact and Reactions

The consequences ripple across the global semiconductor supply chain. European and Southeast Asian buyers who relied on Chinese intermediaries face immediate supply gaps. Major chip manufacturers in South Korea, Taiwan, and Japan typically hold strategic inventories and long-term contracts, providing some buffer, but smaller fabs, MRI service providers, and research institutions will feel the impact more acutely.

South Korea’s presidential office sought to downplay the disruption, stating that “since the Middle East war, we have diversified our import sources to the U.S., and imports from China are very minimal, so there is no impact on our semiconductor industry,” as reported by the Seoul Economic Daily.

For the global AI hardware supply chain, the implications are structural. Wafer production depends on helium at multiple process stages. If helium availability constrains fab throughput, the constraint works its way upstream into GPU and AI chip availability with a lag, potentially affecting the rate at which AI data center capacity can be built globally in the second half of 2026 and into 2027.

What Comes Next

The most consequential aspect of the ban is what it does not specify. There is no expiry date, no defined conditions for lifting, and no phased implementation. If the US-Iran peace process at Bürgenstock concludes successfully and Qatar’s helium production facilities are fully repaired, the rationale for the ban diminishes — but there is no automatic mechanism for its removal.

In the longer term, the ban is expected to accelerate structural changes already underway. China will accelerate domestic helium extraction from LNG tail gas and coalbed methane. The European Union is expected to develop local helium resources and strategic reserves. And buyers around the world who depended on Chinese intermediaries will permanently shift their supply chains to avoid similar vulnerability in the future.

As one analyst put it: “A gas with no substitute, produced by a handful of countries, moving through supply chains already broken by war, has just become harder to obtain for everyone outside China. The announcement that caused it is twelve lines long.”
