Recently, the gravity center of the caustic soda market in Guizhou has been stable. At present, there is no caustic soda production enterprise in the province, and downstream procurement needs to allocate sources of goods outside the province. Local alumina enterprises mainly purchase 99% flake alkali, supplemented by liquid alkali supply. Flake alkali in the region is mainly supplied by enterprises in Northwest China, and most of the liquid alkali is provided by enterprises in Sichuan and Chongqing. The load of the caustic soda supply production area is stable, the output is normal, and the export supply is at a reasonable level. The caustic soda market in Guizhou Province has sufficient supply, the downstream enterprises have moderate procurement, and the transaction price range is stable.
