Masan High-Tech Materials Corp. is a Vietnam-based materials manufacturer engaged in the exploration, mining, processing, and distribution of advanced industrial materials and critical minerals. Founded in 2010 and headquartered in Ho Chi Minh City, Vietnam, the company operates as a subsidiary of Masan Group Corporation and manages the Nui Phao polymetallic mine and processing complex in Thai Nguyen Province. Masan High-Tech Materials offers a comprehensive portfolio of midstream and downstream specialty materials and chemical products, comprising: tungsten chemicals and engineered powders, including ammonium paratungstate, blue tungsten oxide, yellow tungsten oxide, tungsten metal powders, and tungsten carbide powders for use in cutting tools, hardmetal alloys, wear parts, mining equipment, automotive components, and aerospace applications; acid-grade fluorspar (calcium fluoride) for the manufacturing of hydrofluoric acid, fluorochemicals, refrigerants, and aluminum smelting flux; bismuth products, including high-purity bismuth metal, bismuth needles, and bismuth oxide for pharmaceutical formulations, non-toxic lead-replacement alloys, cosmetics, and electronics; and copper concentrates alongside associated byproduct metals for metallurgical processing and electrical equipment manufacturing. The company distributes its products to industrial manufacturers and technology clients across Asia, Europe, and North America. In recent corporate developments, Masan High-Tech Materials entered into a strategic agreement to sell 100% of its equity interest in H.C. Starck Holding (Germany) GmbH to Japan-based Mitsubishi Materials Corporation to optimize its asset portfolio, reduce corporate leverage, and refocus capital on upstream mining and refining operations at Nui Phao while securing long-term tungsten supply and offtake arrangements. Additionally, the company maintains a strategic equity investment and commercial partnership with Nyobolt Limited to supply advanced tungsten materials for the commercial deployment of ultra-fast-charging lithium-ion battery technologies.
