NdPr oxide: how processing sets the price of rare earths

Key insights from this briefing

What is the main midstream bottleneck in the NdPr supply chain?

The bottleneck is separating and purifying rare earths to magnet-grade material, then converting them into finished permanent magnets. Mining alone does not create a secure supply chain if separation, refining and magnet manufacturing remain concentrated elsewhere.

What changed in the US NdPr supply chain in March 2026?

USA Rare Earth commissioned a commercial NdFeB magnet line in Stillwater, Oklahoma, while US defence procurement support included a price floor for NdPr. Together, those measures were intended to support domestic magnet production and reduce reliance on concentrated overseas processing.

Excerpt from this briefing's Industry Insight

NdPr oxide shows how processing capacity sets the strategic value of rare earths. Neodymium and praseodymium form a substantial share of high-strength permanent magnets, while their ores require complex separation to reach usable purity. Monazite can also contain thorium, adding waste-management and regulatory requirements. In March 2026, the US supply chain moved further downstream as USA Rare Earth commissioned a commercial NdFeB magnet line in Oklahoma, while defence price support for NdPr aimed to improve the economics of non-Chinese production.
