Rare earths power modern devices, but supply chains are fragile
These minerals sit inside magnets, screens and defense systems. The U.S. problem is not finding them, but moving them from mine to finished material without a bottleneck.
Rare earth elements power the magnets, screens and defense gear that people use every day, but the U.S. supply chain remains vulnerable. A federal report says the weak link is not mining them — it is getting them from the mine to the magnet.
The U.S. Geological Survey’s 2025 Critical Minerals List includes most REEs, except promethium, because they are essential to the U.S. economy and security and because their supply chains are vulnerable. The minerals are not rare in the Earth’s crust. The hard part is turning them into usable material at scale without hitting a bottleneck along the way.
The chokepoint is the middle of the chain
Rare earth elements may include 17 elements, scandium, yttrium and the 15 lanthanides, though some classifications leave out scandium. The lanthanides are often grouped into light and heavy rare earths, and that split matters because different elements serve different jobs. Some are especially useful for magnets; others are tied to catalysts, glass, phosphors or ceramics.
That means a problem in one part of the chain does not hit every industry the same way, but it can still ripple through factories, clean-tech manufacturing and military procurement. The report also points out that rare earth minerals can come in small concentrations and may contain thorium or uranium, which adds technical difficulty and cost.
Building resilience, not just digging more rock
The report does not present a single fix. Instead, it points toward a mix of federal action, international diplomacy and partnerships, and public-private investment to make U.S. REE supply chains more resilient. The goal is a stronger mine-to-magnet system, one that can hold up when demand rises or geopolitics gets in the way.
That is the larger stakes here. Rare earths are easy to overlook because they are hidden inside familiar products. But if the chain tightens or breaks, manufacturers can face delays, defense programs can lose critical inputs and consumers can feel the strain in price and availability.
