Shin-Etsu Chemical Co., Ltd. (TYO: 4063) is the world’s largest producer of sintered NdFeB (neodymium-iron-boron) magnets by volume, making it a central node in the global rare earth supply chain for electric vehicles, wind turbines, and industrial automation. The company’s shin etsu rare earth magnets division — formally branded as Shin-Etsu Rare Earth Magnets — operates at the intersection of Japan’s advanced chemicals industry and the critical minerals supply chain that Western governments are racing to secure.
Company Overview
Founded in 1926 and headquartered in Tokyo, Shin-Etsu Chemical is one of Japan’s largest industrial companies by market capitalisation, with a group valuation of approximately ¥5–6 trillion. Group revenue for FY2024 (year ended March 2025) reached approximately ¥2.6 trillion (~$17 billion USD). The company operates across four major business segments: PVC and chlor-alkali chemicals, semiconductor silicon wafers, specialty chemicals, and rare earth magnets.
The rare earth magnets segment is smaller than PVC or silicon wafers in revenue terms but is strategically significant given accelerating demand from EV drivetrain and wind energy applications. Shin-Etsu is listed on the Tokyo Stock Exchange under ticker TYO: 4063.
Shin-Etsu Rare Earth Magnet Operations
Shin-Etsu’s primary rare earth magnet manufacturing site is located in Takefu, Fukui Prefecture, Japan. The Takefu facility produces sintered NdFeB magnets across a range of grades, from standard grades for consumer electronics and industrial motors to high-coercivity grades for EV traction motors and direct-drive wind turbine generators. The company is vertically integrated within the magnet supply chain, processing rare earth oxides through to finished magnet products — a capability that distinguishes it from assemblers further down the value chain.
Beyond Japan, Shin-Etsu operates manufacturing facilities in China and has been active in discussions around supply chain localisation as Western OEMs seek to diversify magnet sourcing away from Chinese-only suppliers. Key end markets include EV motors, offshore and onshore wind turbines, industrial servo motors, robotics actuators, and high-end consumer electronics.
Key Rare Earth Inputs
NdFeB magnets require two categories of rare earth input. The base alloy draws primarily on neodymium (Nd) and praseodymium (Pr), combined as NdPr alloy or oxide, which determines magnetic remanence and the fundamental strength of the magnet. High-coercivity grades — required where magnets must retain performance above 150°C, as in EV traction motors — incorporate dysprosium (Dy) and terbium (Tb) as additives. Both heavy rare earth elements are sourced predominantly from China, adding supply chain concentration risk even for Japanese producers.
Shin-Etsu has a confirmed supply relationship with Lynas Rare Earths (ASX: LYC), which supplies NdPr oxide from its Malaysian separation facility at Kuantan. Lynas is the only significant producer of separated rare earth oxides outside China at commercial scale, making its relationship with Shin-Etsu material to Western supply chain security assessments. Japan’s upstream rare earth security is also supported through JOGMEC (Japan Organization for Metals and Energy Security), which funds exploration and strategic stockpiling programmes.
Shin-Etsu Rare Earth in the Global Magnet Market
Shin-Etsu competes in the sintered NdFeB magnet market against Chinese producers including DMEGC Magnetics, Zhongke San Huan, and Ningbo Yunsheng, which dominate on volume and cost. Within Japan, its principal competitors are TDK Corporation and Proterial Ltd (formerly Hitachi Metals), which holds foundational NdFeB magnet patents in certain jurisdictions. The three Japanese producers collectively represent the most significant non-Chinese source of sintered rare earth magnets globally.
Western OEMs — particularly European and North American automotive manufacturers — have long preferred Japanese-sourced magnets where supply volumes allow, on the basis of quality consistency, traceability, and geopolitical risk reduction. This preference has intensified since 2023 as the EU Critical Raw Materials Act and US IRA provisions introduced domestic content and supply chain disclosure requirements.

Shin-Etsu does not publish standalone revenue figures for its rare earth magnets segment. Market share estimates from industry analysts place the three major Japanese producers at a combined 15–20% of global sintered NdFeB production, with China accounting for the remainder. These estimates are subject to revision as Chinese capacity data is not fully transparent.

What rare earth products does Shin-Etsu Chemical produce?
Shin-Etsu Chemical produces sintered NdFeB (neodymium-iron-boron) permanent magnets through its Shin-Etsu Rare Earth Magnets division. These include standard grades for consumer electronics and industrial motors, and high-coercivity grades for EV traction motors and wind turbine generators. The company processes rare earth oxides through to finished magnet products at its Takefu facility in Japan.
Where does Shin-Etsu Chemical source its rare earth materials?
Shin-Etsu sources NdPr oxide from Lynas Rare Earths, which separates rare earth oxides at its Kuantan facility in Malaysia. Heavy rare earth inputs — dysprosium and terbium — are sourced predominantly from China. Japan’s JOGMEC also supports upstream rare earth security through strategic stockpiling and exploration programmes.
How large is Shin-Etsu’s rare earth magnet operation?
Shin-Etsu does not disclose standalone revenue for its magnets segment. The company’s group revenue for FY2024 was approximately ¥2.6 trillion (~$17bn USD). Industry analysts estimate the three major Japanese sintered magnet producers — Shin-Etsu, TDK, and Proterial — collectively account for approximately 15–20% of global NdFeB sintered magnet production.
How does Shin-Etsu Chemical compare to Chinese magnet manufacturers?
Chinese producers including DMEGC Magnetics, Zhongke San Huan, and Ningbo Yunsheng dominate global NdFeB production by volume and undercut Japanese producers on cost. Shin-Etsu competes on quality, traceability, and supply chain security credentials valued by Western automotive and industrial OEMs. As geopolitical pressure on China-sourced magnets increases, Shin-Etsu’s non-Chinese production base has become a commercial differentiator.
What rare earth elements does Shin-Etsu Chemical use in its magnets?
Shin-Etsu’s NdFeB magnets primarily require neodymium (Nd) and praseodymium (Pr) as base alloy inputs. High-coercivity grades for EV motors and wind turbines incorporate dysprosium (Dy) and terbium (Tb) as additives to maintain magnetic performance at elevated temperatures above 150°C. Both heavy rare earth elements are sourced predominantly from China.
