China is the dominant global producer of antimony, which has applications for electric vehicles and military weapons makers.
China has unveiled export restrictions on antimony, a crucial metal for batteries and nuclear weapons, further tightening its hold on the supply chains of strategic minerals in which it dominates global production.
China’s Ministry of Commerce said in a statement on Aug. 15 that antimony and its chemical compounds will be subjected to export controls starting Sept. 15. Traders looking to export the mineral in various forms will now have to obtain a license from the ministry and provide detailed information about the overseas buyers and their export plans.
The latest measures also target technology and equipment used for smelting and separating materials, as well as other products associated with what the ministry referred to as super-hard materials.
A 2021 study published by the U.S. International Trade Commission found that antimony is most commonly used in the United States for fireproofing uniforms and lead-acid storage batteries.
The metal also plays a key role in making a wide range of military equipment, including nuclear weapons and infrared sensors.
Amid tensions with the West, the regime has already tightened its controls over the supply chains of several critical minerals.
