The surge in US rare earth mining, heavily promoted during the Trump administration as a strategic move to reduce dependency on foreign sources, is encountering unforeseen hurdles. Despite ambitious plans to establish a robust domestic supply chain, significant volumes of extracted materials are ending up in Asian markets-primarily China and South Korea-for further processing and refinement. This reliance on overseas capabilities poses a major challenge to US policymakers who sought to secure a fully independent and resilient supply chain for critical minerals vital to technology and defense sectors.

Industry insiders point to a handful of key obstacles complicating efforts to keep rare earths within US borders:

  • Lack of domestic processing infrastructure: Existing refineries in the US struggle to handle the complex chemical processes needed for high-purity rare earth elements.
  • Cost advantages abroad: Asian facilities benefit from economies of scale and decades of technical expertise, making exports financially attractive.
  • Regulatory and environmental hurdles: Strict US environmental regulations add delays and expenses to onshore processing projects.
