China Imposes Export Controls on Antimony and Superhard Materials

New restrictions aim to safeguard national security and fulfill international obligations, effective September 15.

China is the largest producer of antimony, accounting for 48% of global output.
The restrictions apply to six types of antimony-related products, including ore, metals, and oxide.
Exporters must apply for licenses for dual-use items and technologies.
The move is part of China's broader strategy to tighten control over critical minerals.
The U.S. and other countries are seeking to reduce reliance on Chinese mineral supplies.
