TMTPOST — China’s Ministry of Commerce and the General Administration of Customs issued a joint directive on Friday imposing a temporary total ban on the export of helium gas. The emergency export control measure, which explicitly targets customs commodity code 2804290010, takes effect immediately on the date of publication under the legal authority of the Foreign Trade Law of the People's Republic of China. Regulatory officials noted that any subsequent adjustments or rollbacks to the trade restriction will be handled via separate, dedicated administrative announcements. Helium serves as an irreplaceable cooling agent and structural gas across highly technical manufacturing workflows, including semiconductor fabrication, quantum computing research, and optical fiber development. State agencies are restricting strategic raw material flows to safeguard foundational industrial inputs against rising international supply chain fragmentation. Locking down domestic helium reserves stabilizes the cost base for high-consequence semiconductor and defense aerospace manufacturing lines that rely heavily on localized gas purities. This rapid border intervention ensures critical resource sovereignty during a period of escalating global export barriers on advanced technology materials.
