Guizhou Redstar Co., Ltd. was restructured and established in 1999. The company’s listed headquarters is located in Dingqi Subdistrict, Zhenning County, Anshun City, Guizhou Province, and it was listed on the Shanghai Stock Exchange in March 2001. The company’s core business focuses on the research, development, production, and sales of barium salts, strontium salts, and manganese-based products. Its parent company primarily manufactures and sells inorganic chemical products, fine chemical products, and innovative eco-friendly building materials for wall construction (with restrictions on handling hazardous chemicals—specifically limited to barium nitrate, barium chloride, sulfur, thiourea, and sodium sulfide). Barium salts and strontium salts are fundamental inorganic chemical materials, while manganese-based materials fall under the category of electronic chemicals. All three major companies—Guizhou Redstar Co., Ltd., along with its subsidiaries Chongqing Dafu Hongdie Strontium Industry Co., Ltd., and Guizhou Redstar Development Dalong Manganese Industry Co., Ltd.—are recognized as high-tech enterprises. Barium salt products include a range of specialized barium carbonates, various grades of barium sulfate, high-purity barium carbonate, and high-purity barium chloride. Strontium salt products mainly consist of strontium carbonate, strontium nitrate, strontium chloride, strontium hydroxide, and ultra-pure strontium carbonate. Meanwhile, manganese-based products encompass EMD used in primary and lithium batteries, as well as high-purity manganese sulfate. In addition to these core activities, the company is also involved in the production and sale of by-products such as sulfur, thiourea, sodium sulfide, and environmentally friendly bricks made from barium slag. Furthermore, the company operates a liquid logistics terminal and has expanded into the natural pigment industry.

Barium carbonate is primarily used in the production of ceramics and ceramic glazes, functional glass, magnetic materials, electronic components, and other barium salt products. Barium sulfate, on the other hand, finds extensive applications in paints, coatings, plastics, batteries, metallurgy, and more—particularly modified barium sulfate, which is widely employed in industries such as agricultural mulch films, greenhouse protective films, and stretch wrapping films. Strontium salt products are mainly utilized in magnetic materials, liquid crystal glass substrates, metal smelting, fireworks, and other advanced processing of strontium salts. They also have versatile applications in industries like sweeteners, energy-storage fluorescent powders, automotive airbags, and aerosol fire suppression systems. Electrolytic manganese dioxide is predominantly used as a cathode material for primary batteries and lithium-ion secondary batteries, while high-purity manganese sulfate serves as a key precursor for ternary cathode materials in lithium-ion batteries.

The company is firmly committed to implementing its key strategic initiatives, continuously reinforcing the development philosophy that "safety is the bottom line, and environmental protection is our competitive edge." We are maintaining stable production while further enhancing our refined management practices. At the same time, we’re advancing the automation and digitalization of our equipment management systems, strengthening performance evaluation mechanisms, and closely monitoring industry trends in key products as well as downstream demand—enabling us to promptly adjust our sales strategies. As a result, our business performance continues to improve steadily. Through these dedicated efforts, the company has earned prestigious recognitions, including being named a "National Torch Program Key High-Tech Enterprise," a "Guizhou Provincial High-Tech Enterprise," a "Guizhou Provincial Innovative Enterprise," and a "Guizhou Provincial Environmentally Friendly Enterprise." Additionally, we’ve been honored with accolades such as the "National May 1st Labor Medal" and the title of "National Model Enterprise for Harmonious Labor Relations."

Company's growth strategy: Transitioning from a basic chemical raw material supplier to a provider of new energy and advanced materials, while shifting from a labor-intensive enterprise to a high-tech company.

Company's product development directions: Barium and strontium salts—extending the industry chain toward next-generation inorganic functional materials and high-end industries; manganese salts—shifting from primary battery applications to secondary battery applications.

With the care and support from all sectors of society, the company will steadfastly push forward its transformation, upgrading, and management enhancement initiatives. We remain committed to pursuing a path of high-quality, advanced, and specialized growth, leveraging Redstar's diverse strengths and resources. At the same time, we are dedicated to fostering a fair and transparent corporate culture, continuously improving employee satisfaction, and steadily strengthening and expanding the business.
