Gansu Tongshi Technology Co., Ltd. is a technology-driven chemical enterprise located in the Chemical Industry Park of Minle County’s Ecological Industrial Park, Zhangye City, Gansu Province. The company traces its roots back to 1958, when it was founded as the Work-Study Program Base of Haimen Normal School. Over the decades, it evolved through several stages—from a school-run factory to Nantong Reagent Factory, then to Nantong Tongshi Reagent Co., Ltd., and later to Suqian Tongshi Reagent Co., Ltd.—before ultimately relocating to Zhangye, Gansu in 2019. With nearly 70 years of production experience in fluorine chemistry, the company holds a nationally issued production license for industrial chemical reagents.

Established in October 2019, the company has a total project investment of RMB 50 million and covers a planned area of approximately 60 mu (about 4 hectares). The company is primarily engaged in the R&D, production, and sales of high-purity inorganic fluoride salt series products, with its flagship products including high-purity potassium hydrogen fluoride, sodium fluoride, and calcium fluoride, and an annual production capacity of 9,802 tons. As a nationally encouraged project in the field of new chemical materials, its products feature high technological content and low energy consumption, and are widely used in industries such as glass, ceramics, electronics, metal surface treatment, electroplating, and analytical testing.

Thanks to its superior product quality, the company has become a key supplier to subsidiaries of China National Nuclear Corporation (CNNC) and numerous research institutes, and has repeatedly won bids in CNNC's procurement projects for sodium fluoride, calcium fluoride, and other products. The company places great emphasis on industry-university-research collaboration and has established an internship and employment base with the College of Chemistry and Chemical Engineering of Hexi University, engaging in in-depth cooperation in technological breakthroughs, talent cultivation, and the commercialization of research achievements. We warmly welcome domestic and international customers to visit our company for business negotiations, and we are committed to achieving win-win outcomes and creating a brighter future together!
