Recently, the caustic soda market has risen steadily in Gansu Province with the price up 100 yuan/ton. While the mainstream ex-factory price of 32% concentrated liquid caustic soda is 4000-4100 yuan/ton (price 100% consistency), the price of liquid alkali with a concentration of 50% is 4200-4300 yuan/ton (price 100% consistency). Some transactions have concluded at a lower price. At present, as the impact of the local epidemic has eased in the province, some caustic soda facilities resume production and the local caustic soda output has increased accordingly. At the same time, downstream sectors in chemical synthesis operate at an increased run rate, consuming a larger amount of caustic soda. Accompanied by an accelerated supply-demand pattern, the ex-factory price has inched up.
