Welcome to Zhejiang Changshan Changsheng Chemical Co., Ltd. website!


Established in July 1998, Zhejiang Changshan Changsheng Chemical Co., Ltd. is a limited liability company and a private enterprise. At present, our company is located in the Eco-Industrial Park of Changshan County, with a registered capital of CNY 10.5 million, an area of ​​5,192.8 square meters and 178 employees, including 25 engineers and technicians.


Now, our company is a chemical manufacturing enterprise of dyes and pharmaceutical intermediates. In 2006, our company implemented the fine fluorine chemical transformation strategy and adjusted product structure. Equipped with the production lines of 4,000 t/a of 2,4-dichlorofluorobenzene, 5,000 t/a of nitrosylsulfuric acid and 10,000 t/a of potassium fluoride, our company achieved an industrial output value of CNY 250 million and generated annual profits and taxes of more than CNY 60 million in 2019 and 2020.


In recent years, our company has paid great attention to the independent innovation of the enterprise and increased the investment in technical force. A new technology of "high-efficient fluorination method of meta-oil to produce 2,4-dichlorofluorobenzene" won the "New Product and New Technology Appraisal and Acceptance" of province. In the same year, we applied a patent for the project based on the "Comprehensive Utilization Method of Monochloronitrobenzene Mixture by Fluorination Reaction", and obtained an invention patent with completely independent intellectual property rights (Patent No. ZL200910100558.6). By the end of 2019, our company has 2 invention patents and 11 utility model patents. In 2010, our company was recognized as the "Municipal Engineering Technology Research and Development Center for Fluorine-containing Fine Chemicals" by Quzhou City. In 2019, our company was awarded the "High-tech Enterprise" by the Provincial Department of Science and Technology.

As a major move to further implement the tenet of "science and technology as the primary productive force", our company established "Doctor Workstation" and "Academician Workstation" in 2019. 


Under the support of a good management team and a well-established management system, our company has successfully certificated to the ISO9000 quality management system and ISO14001 environmental management system, and has also passed the provincial and municipal clean production audits and the acceptance of safety production standardization.
