Leshan Sanjiang Biotechnology Co., Ltd. was founded by Mr. Xu Zhongyun, a world-renowned forestry scientist, and registered in Leshan National High-Tech Industrial Development Zone in 2003. The company mainly uses Chinese gallnut, a unique local forestry specialty resource, as its raw material to produce a variety of electronic chemicals, pharmaceutical intermediates, food additives and other products.
Our company boasts strong scientific and technological R&D capabilities, with technical personnel who have been engaged in the research and development of deep-processed gallnut products for many years. We are equipped with comprehensive product testing equipment and methods, and have established cooperative relationships with universities and research institutions including the Chinese Academy of Forestry, Nanjing Forestry University and Northeast Forestry University to continuously develop deep-processing projects for forest products.
Leveraging policy advantages, resource advantages and talent advantages, the company has completed a Phase I investment of 30 million yuan and built five gallnut deep-processing production lines, with an annual output of 600 tons of gallic acid, 200 tons of methyl gallate, 300 tons of propyl gallate and 300 tons of tannic acid series products.
Since its establishment, the company has focused on the electronic-grade fine chemicals sector, with emphasis on the R&D and mass production of electronic-grade gallic acid, electronic-grade methyl gallate, electronic-grade propyl gallate and other electronic chemicals. With product characteristics of high purity, high stability and low impurity content, our products are widely used in the electronic information industry, including semiconductors and integrated circuits. The company has become a competitive enterprise with the capability for large-scale production of electronic-grade products in the field of gallnut deep processing in China.
