United States proposes expanding critical minerals list to bolster supply chain security

The U.S. Department of the Interior has proposed adding six new minerals to its 2025 critical minerals list to bolster domestic production and economic security. Recommended by the U.S. Geological Survey (USGS), the proposed additions include copper, potash, silicon, silver, rhenium, and lead. Conversely, arsenic and tellurium are recommended for removal from the list.

If adopted following a 30-day public comment period, the list of critical mineral commodities will expand to 54. This move aims to mitigate risks associated with heavy reliance on foreign imports, particularly from China, which dominates the global market for at least 30 of the 50 minerals currently cited as critical. China has already implemented export restrictions on strategic materials such as gallium, germanium, antimony, graphite, and tungsten.

The strategic challenge extends beyond mining to the processing and refining stages. While the U.S. faces long lead times for new mines, China maintains overwhelming dominance in the manufacturing of permanent magnets essential for electric vehicles, wind turbines, aerospace systems, and military equipment. Experts suggest the primary objective is to build a resilient supply chain that prevents any single nation from disrupting global industries through mineral or processing technology restrictions.
