(Reuters) – China said on Monday it will impose export restrictions on some gallium and germanium products from Aug. 1 to protect national security interests.

Here are some details about gallium and germanium


Germanium ores are rare and most germanium is produced as a by-product of zinc production and from coal fly ash.

China produces around 60% of the world’s germanium, according to the European association Critical Raw Materials Alliance (CRMA), with the rest coming from Canada, Finland, Russia and the United States.

China exported 43.7 metric tons of unwrought and wrought germanium last year, according to Chinese customs.


Gallium is found in trace amounts in zinc ores and in bauxite, and gallium metal is produced when processing bauxite to make aluminium. Around 80% is produced in China, according to the CRMA.

Gallium is used to make gallium arsenide for use in electronics. Only a few companies – one in Europe and the rest in Japan and China – can make it at the required purity, says the CRMA.

China exported 94 metric tons of gallium in 2022, up 25% on the prior year, according to Chinese customs.

U.S. imports of gallium metal and gallium arsenide (GaAs) wafers in 2022 were worth about $3 million and $200 million, respectively, according to USGS.


Small amounts of gallium – around 10,000 metric tons in 2021 – are produced by Japan, Russia and South Korea, according to the United States Geological Survey.

Germany and Kazakhstan also produced it in the past. After prices rallied in 2020 and 2021, Germany announced that it would restart primary gallium production.

Canada’s Teck Resources (NYSE:) is the biggest germanium producer in North America, extracting the material from its Trail smelter in British Columbia.

U.S.-based Indium Corporation also produces germanium, while Belgium’s Umicore makes both germanium and gallium.


The metals are used in high-speed computer chips and for the defence and renewable energy sectors.

Germanium is key to fibre optic cables and also used in high-speed computer chips and plastics as well as infrared radiation.

The metal and its oxides are used in military applications like night-vision devices as well as satellite imagery sensors.

It is also important for low-carbon technologies such as solar cells.

Semiconductor wafers made with gallium arsenide rather than silicon can operate at higher frequencies and are heat resistant, according to U.S. company Wafer World.

They also produce less noise than silicon devices, especially at high operating frequencies, making them useful in radars and radio communication devices, satellites and LEDs, Wafer World says.


Gallium at 99.99% purity in China was last assessed at 1,775 yuan ($245) a kg on Monday, up 5.97% from the previous session and the highest since May 16, Shanghai Metal Exchange data on Refinitiv Eikon showed.

China’s germanium ingot price was last seen at 9,150 yuan ($1,264) per kg on Monday, Shanghai Metal Exchange data on Refinitiv Eikon showed.


In 2010, China restricted export quotas of rare earths to Japan following a territorial dispute between the countries, sending prices of rare earths soaring and Japan scrambling to find other sources of supply. Beijing said at the time the curbs were based on environmental concerns.

Rare earth magnets are used in wind turbines, electric vehicles and defence applications like laser guided missiles.

China has hinted at various times that it could crimp rare earths exports, including in recent years.
