At present, as the arrival volume of calcium carbide market in Hebei is slightly insufficient, the tight supply and demand situation continues. The downstream PVC production enterprises actively engage in purchasing among an upbeat market atmosphere, concluding deals at the mainstream transaction price maintaining the level after the early rise. Currently, while the delivery price of the first-class calcium carbide purchased by local chlor-alkali producers was 4440-4450 yuan/ton, the actual transactions went toward the high end. Recently, as calcium carbide manufacturers have successively increased the operating load, the market supply is recovering, and the subsequent output will increase. Therefore, it is expected that the calcium carbide market in Hebei will operate steadily in a wait-and-see sentiment in the following few days.
