REFILE: China's restrictions on strategic mineral exports

China announced on Tuesday sweeping export controls targeting five metals that are used in defence, clean energy, and other industries. This comes just minutes after the additional 10% tariff imposed by U.S. president Donald Trump on Chinese products went into effect.

China's decision to limit tungsten and indium, amongst other metals, is its latest attempt to weaponise their dominance over the mining and processing a variety of minerals that are vital for everything from smartphones to electric car batteries and infrared weapons and ammunition.

Here is a list of minerals which Beijing has restricted in some manner since 2023.

BATTERY, LITHIUM AND GALLIUM PROCESSING TECHNOLOGY

China has proposed restricting the export of certain technology used in manufacturing cutting-edge batteries and processing critical minerals such as lithium and gallium.

The announcement in January did not specify when the proposed amendments, which were open to public comments until early February and could come into effect, might be implemented.

ANTIMONY, GALLIUM, GERMANIUM

Beijing has banned the export to the United States of three crucial minerals in response to Washington's renewed crackdown on China’s chip industry.

China has gradually introduced export licensing schemes for these three metals over the past 18 months.

Exports of antimony to major buyers such as Japan, India, and South Korea, which is a strategic metal that's used in solar power equipment, munitions and flame retardants had only just begun three months after the export licenses were issued.

China is the world's largest producer of these three metals, and produces or refines half to 90% of the global supply.

RARE EARTHS MAGNET TECHNOLOGY

China has banned exports of technology for making rare earth magnets in December 2023. This ban is added to the existing ban on the technology used to extract and separate critical materials.

Rare earths is a grouping of 17 metals that are used to produce magnets in electronic devices, electric vehicles and wind turbines.

While common in the earth's crust, China has mastered the technically difficult and environmentally-harmful refining process. China produces 90% of the world's refined products.

GRAPHITE

China announced that it will require export licenses for certain graphite products in October 2023 to protect its national security.

China is the top producer and exporter of graphite in the world. It also refines over 90% of all graphite to a material used in almost all EV batteries.
