China abruptly bans helium exports, heightening semiconductor supply fears

China has abruptly implemented an export ban on helium, a critical material used in semiconductor manufacturing. The decision, announced on August 10, adds another layer of uncertainty to the global supply chain for essential tech components.

Helium is indispensable in semiconductor production, serving as a coolant and playing a role in various processes, including the cooling of superconducting magnets in MRI machines. It is also used in aerospace, fiber optics, and quantum computing.

This latest restriction follows a series of export controls China has imposed on other vital materials, including gallium, germanium, graphite, and rare earth elements. The Ministry of Commerce and the General Administration of Customs stated the ban is based on foreign trade law regulations, but provided no specific reasons or duration for the measure. The ban is effective immediately and is expected to apply to virtually all overseas shipments, according to the South China Morning Post.
