On January 12, Shandong Xinfah's PVC plant operating rate increased to full capacity. Today, the ex-factory price for calcium carbide-based SG-5 PVC is quoted at 4,530 yuan/ton, with the manufacturer's total PVC production capacity at 1.1 million tons. PriceSeek's analysis of PVC: Bull-Bear Score: -1. The increase in Shandong Xinfah's PVC plant operating rate to full capacity indicates a significant rise in supply. With the manufacturer's total production capacity at 1.1 million tons and an ex-factory price of 4,530 yuan/ton, the expansion in supply may lead to an oversupply in the market, exerting downward pressure on spot prices. Based on the current changes in supply and demand, this is assessed as a generally bearish factor, with a score of -1.
