Recently, due to the continuous decline in the price of semi-coke, the carbide market has fluctuated downward in Wuhai, accompanied by insufficient orders of manufacturers. Under the influence of inventory pressure, those producers give priority to sales by lowering the ex-factory quotation for many times. At this stage, the mainstream ex-factory price of local first-grade calcium carbide is reduced to 3300-3350 yuan/ton. In the context of low sales volume, some production enterprises even offer their carbide goods at a lower rate in actual transactions.
