Neodymium magnet manufacturers supply the permanent magnets that power electric vehicle motors, wind turbine generators, and defence systems — making them a critical node in the global rare earth supply chain. China accounts for more than 90% of sintered NdFeB magnet production by volume, with the country’s top producers operating at a scale no Western facility currently matches. The following ranking covers the ten most significant neodymium magnet manufacturers by output volume and strategic position, as of 2026.
Each entry in this list produces or processes sintered or bonded NdFeB magnets at commercial scale. Distributors, resellers, and component assemblers that do not manufacture magnets from raw materials are excluded. For background on neodymium demand drivers, see what is neodymium and neodymium price.
How We Ranked the Top 10 Neodymium Magnet Manufacturers
Neodymium magnet manufacturers are ranked primarily by sintered NdFeB production capacity, supplemented by strategic significance for Western supply chain diversification where Chinese and non-Chinese producers cannot be directly compared by volume alone. Chinese producers operate at volumes that dwarf Western peers — a direct consequence of China’s integrated rare earth supply chain from mining to finished magnet. Production figures for Chinese companies are sourced from company filings, USGS Rare Earths Statistics, and industry estimates where precise annual figures are not publicly disclosed.
1. Zhong Ke San Huan Hi-Tech — China (SZ: 000970)

The Outlook for Neodymium Magnet Manufacturers
Demand for sintered NdFeB magnets is forecast to grow in line with EV and offshore wind deployment through the end of the decade — both end markets are structurally dependent on neodymium magnet manufacturers for their primary drive components. The EV sector alone is expected to absorb a significant proportion of incremental magnet supply through 2030, according to Shanghai Metals Market and industry analysts tracking downstream demand.
The principal risk for investors tracking neodymium magnet manufacturers is supply chain concentration: Chinese producers control the raw material, separation, alloying, and magnet manufacturing steps. Western policies — including the US NDAA magnet sourcing restrictions and the EU Critical Raw Materials Act — are designed to accelerate non-Chinese capacity, but MP Materials and USA Rare Earth remain early-stage relative to the output volumes that Chinese peers have built over three decades.

Who are the largest neodymium magnet manufacturers in the world?
The largest neodymium magnet manufacturers by production volume are Chinese: Zhong Ke San Huan Hi-Tech (Sanhuan), Zhenghai Magnetic Material, and Ningbo Yunsheng are consistently cited as the three highest-volume sintered NdFeB producers. Outside China, TDK Corporation and Shin-Etsu Chemical are the most significant producers by revenue and output. China accounts for more than 90% of global sintered NdFeB magnet production.
Does the US produce neodymium magnets?
Yes. MP Materials operates a magnet manufacturing facility in Fort Worth, Texas — the first fully integrated domestic US NdFeB supply chain, processing rare earths mined at Mountain Pass into finished magnets. USA Rare Earth is developing a second facility in Stillwater, Oklahoma. Both companies target US defence and EV customers where non-Chinese sourcing is required under the National Defense Authorization Act. Combined output remains small relative to Chinese producers.
What is the difference between Chinese and Western neodymium magnet manufacturers?
Chinese neodymium magnet manufacturers operate at significantly higher volumes, supported by integrated rare earth supply chains from mining to finished magnet. Western manufacturers — including TDK, Shin-Etsu, VAC, and Arnold — compete on specification, regulatory compliance, and supply chain security rather than price or volume. Western producers supply sectors where Chinese-origin magnets are restricted by defence procurement rules or where high-temperature performance grades are required.
Which neodymium magnet manufacturers supply electric vehicle motors?
The primary EV motor magnet suppliers are Chinese producers — Sanhuan, Zhenghai, and Yunsheng — alongside Japanese manufacturers TDK and Shin-Etsu, which supply Japanese and Korean hybrid and EV platforms. MP Materials is developing supply relationships with US EV OEMs as part of its domestic magnet programme. The specific magnet grades used in EV traction motors are high-coercivity sintered NdFeB, typically containing dysprosium or terbium additions to maintain performance at operating temperature.
Why do neodymium magnet manufacturers depend on China?
The rare earth supply chain — from mining to separation to alloy production to finished magnet — is concentrated in China. Chinese neodymium magnet manufacturers benefit from access to domestic rare earth feedstock, established processing infrastructure built over three decades, and scale economies that Western producers cannot currently match. Export controls on rare earth products, introduced or tightened periodically by Chinese authorities, create pricing and availability risk for non-Chinese manufacturers who depend on Chinese feedstock.
