Recently, the center gravity of the caustic soda market in Guizhou Province has remained stable. Currently, there are no caustic soda production enterprises in the province, and downstream procurement requires the allocation of goods from outside the province. Local alumina enterprises mainly purchase 99% flake alkali, with liquid alkali as a supplement. The flake alkali in the region is mainly supplied by the Northwest enterprises, while liquid alkali is mostly provided by enterprises in Sichuan and Chongqing. The caustic soda production areas have stable facility loads, normal production, and reasonable levels of export goods. There is sufficient supply of caustic soda in Guizhou Province, and downstream enterprises′ procurement is mild, with transaction prices remaining unchanged.
