Shanghai BaiJin Chemical Group Co., Ltd, headquartered in Shanghai, was established in 1990. With carbon disulfide production as the major business, BaiJin Group consistently extend the industrial chain of fine chemicals and chemical fibers, and endeavor in international trade, technical export, and R&D of science of technology. As a professional group company with the largest production scale, the most complete technical processes and the most comprehensive technologies in domestic and international carbon disulfide markets, it is honored as a vice-president unit of CISIA and a president unit of carbon disulfide association With 8 subordinates, BaiJin Group not only has an experienced and professional team working on R&D, technical management and project construction, but also has ISO9001: 2008 Quality Management System, ISO14001: 2004 Environment Managemenet System and GB/T 28001-2001 Occupational Health and Safety Management System.
BaiJin Group implements the strategy of investing and founding factory close to raw material, markets, and customers, and continually strengthens the development of carbon disulfide as its main business. It owns 15 independent patents and is applying for 2 international patents. Successively, 6 carbon disulfide manufacturing plants in Chongqing, Sichuan, Xinjiang, Anhui, Shandong, and Jiangsu respectively have been established, with an annual output of 220, 000 tons. In the meanwhile, a nationwide marketing network helps achieve the dominating market share in the industry. In addition, the carbon disulfide product of BaiJin brand has been exported to many countries and regions, including Indonesia, India, Taiwan, Thailand, Japan, Korea, and Brazil In 2008, BaiJin Group set a pioneering example by inventing the patented technology of producing carbon disulfide with natural gas process and exporting whole sets of equipments to overseas market and built up a production line of carbon disulfide with production capacity of 35 KT in Indonesia. In 2011, BaiJin Group cooperated with Phil's India again to develop the carbon disulfide market in India and to expend its industry to international field.
Regional advantages have been taken into full play by BaiJin Group to expand the space of industrial chain and implement the long-term strategic objectives of development. In Chongqing at western China, BaiJin Group has introduced the listed company Hubei Xingfa Group to develop the fine chemicals industrial chain for the 20 KT DMSO production line that leads the world in terms of scale and competitiveness. In Xinjiang at northwestern China, a first-phase project of 50KT cotton pulp production line has been set up at Akesu to take the most use of its resource superiority of cottons. In Shanghai at eastern China, it makes the best of location advantages as well as resource advantages to promote technical R&D and the export of technology and equipment, expand domestic and overseas trade and boost its development in capital market.
