The company is a chemical enterprise primarily engaged in the production of dyes and pharmaceutical intermediates. In 2006, the company implemented a strategic transformation towards fine fluorine chemicals and adjusted its product structure. Currently, the company has production lines with an annual capacity of 4,000 tons of 2,4-dichlorofluorobenzene, 5,000 tons of nitrosyl sulfate, and 10,000 tons of potassium fluoride.
