Dexing Longsheng Calcium Carbonate Co., Ltd. (德兴市龙圣碳酸钙有限公司) is a China-based manufacturer specializing in the production and supply of various forms of calcium carbonate and related compounds. Established in Dexing City, Jiangxi Province, the company has emerged as a regional leader in the field of non-metallic mineral product processing, offering a wide range of chemical materials tailored for food, pharmaceutical, and industrial applications.
The company focuses on the processing and commercialization of high-purity calcium-based chemical products. Its core product lines include:
These products serve multiple industries, including food processing, pharmaceuticals, plastics, rubbers, coatings, and environmental protection sectors. The company's calcium carbonate is widely used as a functional filler or additive due to its fine particle size, high purity, and chemical stability.
Dexing Longsheng has specialized in achieving high-level material fineness and chemical consistency across its product range. Its nano and active calcium carbonate products are tailored to meet the demands of high-performance industrial applications. The company emphasizes quality control and process optimization, ensuring uniformity in particle distribution and moisture content.
Key differentiators include:
Dexing Longsheng primarily serves domestic Chinese industries but is also positioned for international exports, particularly in:
Its products are utilized by manufacturers in food processing, PVC and plastic industries, rubber production, and coatings.
While specific factory size or production capacity details are not publicly disclosed, available trade records and industry listings confirm that the company engages in bulk manufacturing with scalable output capabilities. Dexing Longsheng maintains in-house laboratories for testing and material characterization, ensuring compliance with performance and safety standards across applications.
Although no direct certification details were found in public databases, the company's product categories—particularly those serving the food industry—imply adherence to national Chinese food additive standards and potentially compliance with GB (Guobiao) standards. However, verified certification (e.g., ISO, HACCP, or FDA) was not located.
According to records available on ImportYeti and other trade data platforms:
While specific revenue or profitability figures are not available from public financial disclosures, the consistent export activity suggests a healthy mid-sized operation with stable demand across multiple regions.
The business is reportedly led by Yu Weilong, who is listed as the principal contact and business owner in several Chinese business directories and B2B platforms such as Qichacha and 1688.
While direct testimonials are limited due to language and platform constraints, repeat purchases recorded in B2B transaction logs and trade platforms reflect consistent customer satisfaction, especially for the quality consistency of calcium carbonate grades tailored for different industrial requirements.
Dexing Longsheng Calcium Carbonate Co., Ltd. continues to strengthen its footprint in the calcium carbonate market through continuous innovation in product development, commitment to quality, and expanding trade relationships globally.
