September 18th News
As of September 17, 2026, the Chinese PVC spot market continued to operate weakly, with dealers' quotes continuously declining slightly. The market is characterized by a strong wait-and-see sentiment and low trading volume. According to the average difference method, the current PVC price is in a clear downward trend, with the one-year cycle price at a medium-low level. In the short term, it remains under pressure due to the weakening futures market and insufficient demand support, but the long-term downward space is relatively limited.
