Thanks to its stable physical and chemical properties, sodium sulfate has an extensive range of applications. The papermaking industry is our key downstream sector where we have built long-term expertise. Used as a cooking aid in pulping, it effectively breaks down lignin and increases pulp yield. It can also partially replace calcium carbonate as a filler, helping paper mills cut production costs and improve paper formation and drainage. Numerous domestic containerboard and specialty paper manufacturers place regular orders. Leading paper enterprises in Indonesia and Malaysia also make large-scale purchases from China throughout the year.

Outside the papermaking sector, daily chemicals and detergents account for the largest global consumption volume. As an essential filler for laundry powder and phosphate-free detergents, it sees persistently strong import demand from manufacturers across India, the Middle East and South America.
