2Spot Overview

Based on the Changzhou market in East China, today's cash warehouse price for carbide method type five in East China is 4,650 yuan/ton, unchanged from the previous trading day. 。

The domestic PVC spot market remained generally stable, with slight fluctuations in the morning session. In the afternoon, as bulk commodities weakened, PVC spot transaction prices were adjusted downward. During the week, both supply and demand continued to increase. However, uncertainties in export policies and the release of new domestic production capacity put pressure on spot prices. In East China, carbide-based PVC type 5 spot prices (ex-warehouse) were at 4,620–4,760 yuan/ton, while ethylene-based PVC was at 4,800–5,000 yuan/ton.

5. Price Forecast

In the short term, there is limited change in the supply and demand of the domestic PVC spot market; however, the increased trial runs of new capacity units have raised concerns about supply within the industry. Unclear foreign trade export policies have suppressed export demand. In the short term, industry costs remain firm, coupled with maintenance of some upstream units, providing support to the price floor of the PVC market. It is expected that the market will remain in a stalemate within a range in the near future. The current price for the calcium carbide-based five-type PVC in East China is estimated to be between 4,650 and 4,800 yuan/ton for prompt delivery with cash payment.
