Analysis review
According to the SunSirs’ commodity analysis system, caustic soda prices rise over the weekend this week. In Shandong Province, the mainstream market price for 32% ion-exchange membrane caustic soda is around 800-880 RMB/ton. In Jiangsu Province, prices are stable, with the mainstream market price for 32% ion-exchange membrane caustic soda at around 850-930 RMB/ton. In Inner Mongolia, prices are consolidating, with the mainstream market price for 32% ion-exchange membrane caustic soda at around 2,700-2,800 RMB/ton (Equivalent to 100%). In Shandong Province, caustic soda prices remain stable during the week, with a slight increase over the weekend. Due to the fact that equipment that had been undergoing maintenance has not yet been restored, companies are facing minimal inventory pressure. Major downstream companies are raising the price of liquid caustic soda, leading to rising prices across the region. Alumina purchases are primarily on-demand, and non-aluminum purchases are primarily on-demand.
Future outlook:
Analysts from SunSirs believe that the price of caustic soda has risen slightly over the weekend. The recent domestic downstream demand is still good, and the inventory pressure of caustic soda companies is not great. There is a game between supply and demand.. It is generally expected that caustic soda will maintain a strong market in the later period, depending on the downstream market demand.
