At present, as the calcium carbide market operates in a weak trading atmosphere in Wuhai, the mainstream transaction price has decreased compared with the previous period. At this stage, while the mainstream ex-factory price of first-class calcium carbide is 3800-3850 yuan/ton in the region, the low-end transaction price is around 3780 yuan/ton. As the domestic acetylene-based PVC price keeps falling, the downstream chlor-alkali enterprises gradually increase the pressure on the calcium carbide purchase price. The abundant arrival of goods to major consumer areas makes it more difficult to improve the market atmosphere. Therefore, as is expected that the carbide market can hardly improve in Wuhai, we do not rule out the possibility of the declining trend.
