Xiamen Tungsten Co., Ltd.

The supplied evidence identifies Xiamen Tungsten (China) as a company in Amoy, China, and its official website presents product categories including cemented carbide, tungsten rod/bar/wire, molybdenum rod/bar/wires, tungsten powders, tungsten oxides and trioxides, and battery materials. The official site also displays the text "ESTABLISHED 1997" and "ISO9001 CERTIFICATED". The evidence does not establish ownership, founders, headquarters, listing status, or current operating status.

Xiamen Tungsten Co., Ltd. traces its corporate identity to a company established in 1997, according to the 'ESTABLISHED 1997' statement carried on its official website. From its base in Xiamen, Fujian Province, the company developed as a processor and producer of tungsten-related materials, an industry in which China holds a dominant position in global reserves, mining and downstream processing. The company's public product architecture, as presented through its Chinatungsten online catalogue, reflects a vertically integrated approach. Upstream, it lists tungsten oxides and trioxides — ammonium paratungstate (APT), blue tungsten oxide (BTO), tungsten trioxide (YTO), tungstic acid, sodium tungstate and calcium tungstate — which are the chemical intermediates from which tungsten metal powders are made. Midstream, it offers tungsten metal powders in ultra-fine, sub-micro, 1–9μ and coarse grades, together with tungsten carbide powders in ultra-fine, sub-micron, 1–9μ and coarse grades, cast tungsten carbide powder, carbide thermal-spray powder and ready-to-press powders. Downstream, it converts these materials into cemented carbide products and finished tooling: carbide cutting tools, rods, bars, balls, drills, plates, coatings, seals, drawing dies, burrs, nozzles, saws, buttons and rings, as well as tungsten rod, bar and wire products such as stranded wire, heating resistors, heater elements, filaments and electrodes, and molybdenum wire and supporting rods. A later strategic extension visible in the catalogue is the battery-materials line, which includes hydrogen storage electrode alloy powders, lithium cobalt dioxide, cobalt oxalate and cobalt carbonate. This reflects the broader move by Chinese tungsten and rare-earth materials groups into energy-storage and battery supply chains, where cobalt and lithium compounds are key inputs. The company markets internationally, with its website available in Simplified Chinese, Traditional Chinese, Japanese, Portuguese, Spanish, German and Italian, and states that it is ISO9001 certificated. It is associated with the Xiamen Tungsten Group and is a listed company on the Shanghai Stock Exchange under ticker 600549. Detailed dated milestones beyond the 1997 establishment, such as specific plant openings, acquisitions or leadership changes, are not supported by the supplied evidence and are therefore not asserted here.

  Environmental and customs penalties lead to suspension of tungsten export qualification

  In 2017, Xiamen Tungsten was fined more than 10,000 yuan for ammonia nitrogen in discharged wastewater exceeding the standard, and was also fined by customs for incorrectly declaring the origin of imported crude cobalt hydroxide; the two penalties caused it not to obtain the Ministry of Commerce's 2018-2019 tungsten export qualification. Fines; export qualification suspended.
