China tightens control over rare earth exports

China has enacted new regulations asserting state ownership over rare earth materials, critical for semiconductor production, with a rule effective from October 1. Additionally, on December 3, the Ministry of Commerce announced a ban on the export of dual-use items such as gallium, germanium, and antimony to the US. These moves are expected to impact industries reliant on these materials, especially solar cell production and semiconductor manufacturing.

As the world’s largest supplier of rare earths, China has long dominated the market due to its lax environmental regulations, which allow for large-scale extraction and refining. However, with many countries looking to reduce their dependency on China, the long-term effectiveness of these export restrictions may diminish. Nations like the US and Australia are expanding their rare earth production lines, and efforts to recycle rare earth materials are also gaining traction.

Despite these efforts, challenges remain in replicating China’s refining capabilities, as many countries are limited by technical and environmental obstacles. Notably, the US has partnered with Australia’s Lynas Corporation to build a rare earth extraction facility, aiming to strengthen its supply chain.

The future of the rare earth market may shift toward the development of substitute materials, although creating viable replacements is a time-consuming process. In this ongoing battle, China has already secured patents for some high-performance materials that could serve as alternatives, indicating that the competition could soon turn to technological innovation and patent rights.
