Xiamen Tungsten rare earth operations place the company among China’s most strategically diversified critical mineral producers — one of the few listed conglomerates controlling both rare earth and tungsten supply chains simultaneously. Incorporated in 1997 and listed on the Shanghai Stock Exchange (600549.SH), Xiamen Tungsten Co., Ltd. has built downstream integration across NdFeB permanent magnet materials, rare earth smelting and separation, and battery cathode materials through its separately listed subsidiary.
Company Overview
Xiamen Tungsten was incorporated in 1997 and is headquartered in Xiamen, Fujian Province, China. The company carries registered capital of CN¥1.42 billion and trades on the Shanghai Stock Exchange under ticker 600549.SH. Its core business spans two designated critical mineral categories: rare earth processing and tungsten products.
The company operates through distinct business segments covering rare earth smelting, separation and downstream manufacturing, alongside tungsten concentrate processing and cemented carbide production. In 2021, Xiamen Tungsten listed its battery materials division separately as Xiamen Tungsten New Energy Materials Co., Ltd. (688778.SH) on Shanghai’s STAR Market — a structure that gives investors direct exposure to the EV battery supply chain as a standalone vehicle.
Xiamen Tungsten Rare Earth — Smelting, Magnets and Battery Materials
Xiamen Tungsten rare earth processing covers the full value chain from smelting and separation through to finished magnetic and battery materials. The company produces neodymium-iron-boron (NdFeB) permanent magnet materials — the dominant magnet type in EV drive motors, wind turbine generators, and industrial robotics — alongside rare earth alloy and metal products.
Rare earth battery materials represent a second manufacturing stream, focused primarily on nickel-metal hydride (NiMH) battery applications. NiMH batteries use lanthanum-rich mischmetal as an anode material and retain a significant market in hybrid vehicles and consumer electronics despite lithium-ion growth.
On the separation side, Xiamen Tungsten operates rare earth smelting and solvent extraction capacity in Fujian — one of China’s established rare earth processing provinces. For context on how China’s processing infrastructure shapes global supply, see rare earth separation technology developments and the broader neodymium supply chain.
Tungsten Operations and Critical Mineral Diversification
Tungsten is the business Xiamen Tungsten was built on, and it remains a core revenue contributor. The company processes tungsten concentrate into cemented carbide (tungsten carbide) products used in industrial cutting tools, mining drill bits, and wear-resistant components, alongside pure tungsten metal products for electronics and defence applications.
The strategic relevance of this dual positioning is material. Both tungsten and rare earth elements appear on the critical minerals lists of the United States, European Union, and United Kingdom. A producer controlling meaningful capacity in both categories occupies an unusual position in the supply chain — one that Western procurement planners and policy analysts are increasingly scrutinising as export control risks multiply.
China’s dominance in tungsten processing mirrors its position in rare earths: USGS data consistently shows China accounting for over 80% of global tungsten mine production, with Xiamen Tungsten among the country’s largest tungsten carbide producers.
Battery Materials — The EV Growth Angle
The listing of Xiamen Tungsten New Energy Materials (688778.SH) on the STAR Market reflects a deliberate strategic decision: isolate the high-growth battery cathode business for independent capital market access. The subsidiary develops and manufactures cathode materials for lithium-ion batteries — including ternary (NMC/NCA) cathode materials used in EV battery packs.
This positions Xiamen Tungsten across two distinct EV supply chain inputs: rare earth permanent magnets for drive motors, and lithium battery cathode materials for energy storage. Few companies outside China span both. As global EV production scales, demand for both material categories is forecast to grow substantially through 2030 and beyond, according to analyst projections cited by rare earth energy transition analysis.
The battery materials subsidiary’s STAR Market listing provides a more transparent financial window into this segment than consolidated reporting alone — a factor relevant to investors tracking the lithium battery materials supply chain.
US Legal Context and Supply Chain Scrutiny
In February 2020, Tan Hongjin — a scientist who had worked at Phillips 66 — was sentenced to 24 months in federal prison by a US court for theft of proprietary battery technology information. Court documents in the case alleged that Tan had received a job offer from Xiamen Tungsten and that the arrangement involved providing access to technical knowledge. Xiamen Tungsten was not charged in connection with the case.
A US Department of Justice official, commenting at the time of sentencing, stated that the case uncovered what was described as China’s persistent attempts to acquire American intellectual property. The case is a matter of public record and is referenced in US government commentary on technology transfer risks in the critical minerals and battery materials supply chains.
Western procurement teams and institutional investors conducting supply chain due diligence on Chinese battery and rare earth material suppliers should be aware of this public record as part of standard counterparty assessment.

Xiamen Tungsten Rare Earth in the Global Market
Xiamen Tungsten rare earth operations sit within China’s tiered rare earth processing hierarchy — below the six state-controlled mining quota groups at the extraction level, but with significant downstream manufacturing capacity in magnets and battery materials that places it in direct competition with other listed rare earth processors including GRINM, DMEGC, and Shenghe Resources.
Western exposure comes primarily through the magnet supply chain. NdFeB magnets manufactured in China — including by producers such as Xiamen Tungsten — supply global EV and wind turbine manufacturers either directly or through trading intermediaries. As Western governments push to diversify magnet supply away from Chinese producers, Xiamen Tungsten’s position in that supply chain is subject to the same policy headwinds affecting the broader sector.
