Samarium at 346x: Rare Earth Supply Risk Hits Equipment Buyers

Samarium now sells for as much as 346 times its Chinese price in North America, a gap that previews what industrial buyers everywhere would pay if Chinese exports of rare earth metals stopped. Jet engines, industrial motors, electric vehicles and wind turbines all run on rare earth magnets, and most U.S. manufacturers still source them from China at Chinese prices. Outside China, dysprosium costs five times as much and yttrium more than 100 times as much; Japan has begun asking Washington for help before its yttrium supply runs out at year-end.

The structural problem sits one step upstream of the magnet plants. According to Canaccord Genuity, China controls more than 90% of the world’s 210,000-tonne rare earth metallization capacity — the step that turns oxides into metal and casts the alloy strip feeding magnet lines. Strip casters now take up to two years to deliver, and Canaccord’s channel checks found buying them from China “impossible under current export controls.” American manufacturers buy about 48,000 tonnes of rare earth magnets a year; in 2025 the U.S. made just 300 tonnes. Washington has started intervening — under a 10-year agreement with MP Materials, the Pentagon guarantees a $110 per kilogram floor price for NdPr — and new capacity is emerging: REalloys (NASDAQ: ALOY) operates a metallization facility in Euclid, Ohio, holds rights to roughly 80% of the Saskatchewan Research Council’s expanded output including about 525 tonnes of NdPr metal annually, and carries a 15-year offtake for 15% of Phase 1 production from the Tanbreez project in Greenland, with $122.4 million in cash at the end of June funding its expansions.

For buyers of pumps, compressors and rotating equipment, this is not an abstract commodities story: the permanent magnets inside high-efficiency motor rotors and magnetic drive couplings trace straight back to this supply chain. Canaccord expects Western magnet plant capacity to more than triple to about 70,000 tonnes by 2030, but non-Chinese metal and alloy capacity to reach only 38,000 tonnes — roughly half of what those plants will need — which means delivery slots for magnet-dependent equipment will tighten before prices calm down. Procurement teams should therefore change how they qualify motor and equipment suppliers. Ask exactly where the magnets, and the metal behind them, come from; a supplier with no answer on metallization source is carrying a delivery risk it cannot see. Treat long-lead items the way the strip-caster market already does — a two-year quoted lead is now real, not a negotiating position — and lock frame agreements early for any equipment specified with rare-earth magnet duty. Watch price mechanisms like the $110/kg NdPr floor too: guaranteed minimums will start appearing in quotes as suppliers pass through their own hedging costs. ING’s warning that China’s grip is “industrial rather than geological” cuts both ways: the constraint is a factory problem, and factory problems are exactly what procurement is paid to anticipate.
