China has imposed a temporary ban on exports of helium to take effect immediately, as analysts said the country was moving to ensure its domestic chipmakers could maintain production amid a severe disruption in global supplies of the gas.

The announcement – issued by the Ministry of Commerce and the General Administration of Customs on Friday – did not specify any destination markets or exemptions, implying that the ban applies to all overseas shipments.

Helium, a by-product of liquefied natural gas production, is a critical input for a range of sectors including semiconductors, medical equipment and aerospace.
