Recently, due to the continuous increase in deliveries from other ports, there has been a certain adjustment in the supply and demand relationship of PVC market in North China. From an analysis, the local carbide-based PVC plant has not operated at high rates, while the ethylene-based plants have gradually resumed, resulting in a slight increase in the supply of goods. At the same time, the increased sales to other areas from Northwest China has led to difficulties among local manufacturers. In terms of downstream demand, as plastic processing enterprises in major consumer areas such as East China and South China have insufficient production, the demand for PVC in the market continues to be weak.
