Affected by the increase of regional arrival of goods and the intensified imbalance between supply and demand, the carbide market could hardly maintain a stable situation in Shandong in the early stage, with individual purchase prices slightly loosened. At this stage, while the mainstream delivery price of first-class calcium carbide purchased by chlor-alkali enterprises is mostly 3930-4050 yuan/ton in this region, the delivery price in regions with long transportation distance is about 4130 yuan/ton. With the price focus of acetylene-based PVC remaining at a low level, chlor-alkali enterprises under great pressure continue to depress the purchase price in the context of stable arrival of calcium carbide goods, leading to the difficulties in the stability of the market focus.
