Recently, Aluminum Corporation of China, the world's second-largest supplier of alumina, announced a 5% reduction in spot prices to RMB 2850 per ton, marking the first time this year that the company has lowered its alumina prices. And there are reports that the operating load of alumina plants in some areas has also been reduced, leading to a weakening of downstream alumina industry support for the caustic soda market. At present, some caustic soda enterprises in Chongqing, Henan and other regions in China are feeling pressure on their shipments, and the wait-and-see atmosphere among enterprises has increased. The factory quotation is stable, and the transaction price of some sources has decreased by 50 yuan/ton.
