1. On Tuesday, international crude oil prices fell, with ICE Brent May futures down by $1.19 per barrel to $71.62.

2. The price of raw material Bisphenol A in East China was stable at 9400 yuan/ton.

3. This week, the ex-factory prices of domestic PC manufacturers remained steady or decreased by 100 yuan/ton, while Zhejiang Petrochemical's auction price dropped by 200 yuan/ton.

4. Downstream demand for essential purchases remains limited, with some continuing to decline.

Core logic: Cost pressures are increasingly evident, but the contradiction between supply and demand is difficult to resolve in the short term, leading to a weak and low consolidation of the market situation.

III. Market Outlook

This week, as some domestic PC ex-factory prices continue to fall, the price difference with raw material Bisphenol A has narrowed to within 3000 yuan/ton. The cost pressure on the PC industry is increasing, but the current capacity utilization rate is still around 85%, indicating a high level of supply of domestically produced materials. However, downstream demand remains insufficient. It is expected that the weak trend of the domestic PC market will be hard to reverse, likely maintaining a weak and fluctuating trend. Attention should be paid to the extremely low prices of domestically produced materials and their impact on market sentiment and further trading dynamics.
