Neodymium (Nd, atomic number 60) is a light rare earth element whose primary commercial use is in neodymium-iron-boron (NdFeB) permanent magnets, the strongest commercially available magnets. These magnets are essential inputs for electric vehicle traction motors, direct-drive wind turbine generators, hard disk drives, MRI machines, and guidance systems in precision munitions, making neodymium a strategically significant material in the energy transition and in defense industrial policy.
China dominates the neodymium supply chain at multiple stages. According to the US Geological Survey's annual Mineral Commodity Summaries, China accounts for the majority of global rare earth mining and an even larger share of separation, refining, and magnet manufacturing capacity. This concentration has driven a wave of industrial policy responses:
- The EU Critical Raw Materials Act, which entered into force in 2024, lists rare earth elements including neodymium as both "critical" and "strategic" and sets benchmarks for domestic extraction, processing, and recycling capacity by 2030.
- The US Defense Production Act has been used since 2020 to fund rare earth separation and magnet production projects, including support for MP Materials' Mountain Pass facility in California.
- Japan restructured its rare earth sourcing after China's 2010 export restrictions during the Senkaku/Diaoyu dispute, investing in Lynas Corporation's Malaysian processing plant.
Neodymium prices are volatile and politically sensitive. Beijing's introduction of rare earth export licensing measures in 2023–2024, covering related processing technologies and some downstream materials, reinforced its perception as a coercive economic tool. For MUN delegates and researchers, neodymium is a useful case study in resource interdependence, industrial policy, and the limits of WTO disciplines on export restrictions (see the China — Rare Earths dispute, DS431/432/433, where a WTO panel and the Appellate Body in 2014 ruled against China's export quotas).
Example
In 2010, after a maritime collision near the Senkaku/Diaoyu Islands, Japanese manufacturers reported delays in Chinese rare earth shipments including neodymium, prompting Tokyo to diversify supply through investments in Australia's Lynas Corporation.
Frequently asked questions
It is the key ingredient in NdFeB permanent magnets, which have no commercially viable substitute in EV motors, wind turbines, and several defense applications, and its supply chain is heavily concentrated in China.
