Rare earth magnets: the critical supply chain China dominates and the West is racing to build

What it is

NdFeB (neodymium-iron-boron) rare earth permanent magnets are the strongest commercially available permanent magnets. The primary rare earth ingredients are neodymium and praseodymium (NdPr); dysprosium and terbium are added to raise coercivity, preventing demagnetization at the high operating temperatures inside EV motors. Each electric vehicle traction motor contains roughly 1-3 kg of these magnets; offshore direct-drive wind turbine generators require 200-600 kg per unit. Military applications span missile guidance actuators, naval propulsion motors and drone airframes, which puts magnet supply at the centre of defence procurement debates. A world-news reader tracks this beat because China controlled approximately 60% of global rare earth mining, 91% of refining and 94% of finished sintered NdFeB magnet production as of 2024, making every dependent industry a leverage point in geopolitical disputes with Beijing.

History

Rare earths were first commercially mined at Mountain Pass, California (US), which dominated global output through the 1980s. China became the low-cost producer during the 1990s and by 2010 controlled roughly 97% of global rare earth supply. Beijing imposed quota cuts and export taxes in 2010, triggering a WTO complaint that the US, Japan and the EU filed and won in 2014. The 2010-11 price spike prompted magnet makers in Japan, the US and Europe to invest in recycling and material thrifting, but prices collapsed after the WTO ruling and China's dominance rebounded. Lynas opened the Mount Weld mine in Western Australia and the Kuantan separation plant in Malaysia in 2013, becoming the only significant non-Chinese producer, processing roughly 14,000-16,000 metric tons of REO annually through the mid-2010s.

Current state

China's April 2025 export controls on seven heavy rare earth elements, including dysprosium and terbium, related alloys and NdFeB magnets triggered the price shock documented in NdPr価格が4カ月で160%急騰し1キロ137ドルに達した後に反落、重希土類は130%上昇: NdPr surged from US$53/kg in January 2025 to US$137/kg by end-April before correcting. Beijing expanded the regime in June 2026 with Announcement No. 26 (effective July 1, 2026), adding whistleblower rewards for illegal exports and blacklisting US rare earth producers including MP Materials, as reported in 中国がMPマテリアルズとUSAレアアースをブラックリストに追加し、管理体制を拡充. A separate January 2026 de-facto export freeze covering Japanese buyers with military links compounded Japan's exposure, given Japan's continued 60-70% dependence on Chinese rare earth supply. The US Department of Defense countered with a US$400 million equity stake in MP Materials and a US$110/kg NdPr price-support floor, a model the US then extended to allied partners as documented in 米国が国防総省型の下限価格を同盟国へ拡大、プロジェクト・ボールトとG7備蓄公約が西側鉱物の政策手段を再構築.

Relationships

Neodymium is the primary magnetic element in NdFeB magnets; dysprosium is the heavy rare earth additive that allows magnets to operate above 150°C without losing performance, making it essential for high-torque EV motors. Both flow through China's separation and alloying complex before reaching magnet producers in China, Japan and a nascent Western base. MP Materials (mp-materials) is the US's integrated mine-to-magnet producer: Mountain Pass in California supplies rare earth concentrate, processed domestically and converted to NdFeB magnets at the Fort Worth, Texas "Independence" facility, which began commercial production in December 2025, as detailed in MPマテリアルズがテキサスでNdFeB磁石生産を開始、国防総省が筆頭株主に. Lynas (lynas) operates outside China as the world's second-largest rare earth producer, with its Mount Weld (Australia) mine and Kuantan (Malaysia) separation plant; its planned Texas separation facility has stalled without DoD offtake, as described in 国防総省がMPマテリアルズを支援する中、ライナスのテキサス工場は「進まない公算」。マレーシアは2036年まで再認可. The EU is pursuing domestic processing targets under its Critical Raw Materials Act, with the second strategic project selection in March 2026 covered in EU重要原材料法の第2次戦略プロジェクト一覧、リチウム・ニッケル・コバルト・希土類で47件を追加。最初の許認可は24カ月以内に処理, which sets a 40% EU-based processing benchmark for rare earth consumption by 2030.

What to watch

The critical near-term questions are whether China's July 2026 export-control tightening, covering end-user vetting for every rare earth and magnet shipment, produces further supply disruptions for Western motor manufacturers; whether MP Materials reaches nameplate NdFeB magnet output at its Fort Worth facility by end-2026; whether Lynas can meet the radioactive-waste condition attached to the Kuantan relicence before its 2031 deadline while growing output; and whether Australia's Iluka Resources can commission the Eneabba refinery in Western Australia, which would be the first non-Chinese facility capable of separating heavy rare earth oxides including dysprosium at commercial scale. Longer-term, motor-efficiency engineers are investing in dysprosium-reduction techniques and switched reluctance or ferrite-motor substitution that could reshape demand for heavy rare earths before 2035, narrowing the window in which China's chokehold on dysprosium carries maximum leverage.
