About us

Basic chemicals are necessary inputs for many manufacturing industries. However, the current supply of basic chemicals in Vietnam only meets about 40% of domestic demand. As the country industrializes and modernizes, the demand for industrial chemicals such as Caustic Soda, HCL, Chlorine, Sodium hypochlorite (Javen), and PAC are increasing. Mastering technology and producing domestically will save a significant amount of foreign currency used for imports, and helping domestic enterprises proactively organize effective production. Dong A Joint Stock Company has steadily grown for over 20 years, thanks to the expertise and management experience of experts in the chemical and paper industries, as well as the efforts of all employees.

We currently operate a 35,000m2 factory with 250 workers employed in three continuous shifts. In 2019, we launched the second phase of our Ion-exchange membrane electrolyte technology, which increased our plant's capacity to produce 20,000 tons of concentrated caustic soda per year. This is the most advanced technology in the field of Chlor-Alkali production in developed countries. We plan to expand the factory's capacity to 40,000 tons of concentrated caustic soda annum by 2023. Our product line includes Caustic soda, HCL, Chlorine, Sodium hypochlorite, liquid PAC, and high-quality PAC powder. We are proud to be a reliable partner for customers such as Samsung Electronics., Hoa Phat Steel Group, Ton Hoa Sen Group, An Hoa Paper, Masan Group, DMC Petroleum Chemicals, Quang Ninh Mining Chemicals, Song Duong Surface Water Plant …
