II. Trend Forecast for Sample Inventories

For the period from October 8 to October 11 (4 days), barring any sudden disruptive news, arrivals of styrene vessels are expected to remain relatively stable. There is a slight expectation of demand recovery among downstream users after the holiday; however, high styrene prices are hindering price transmission to downstream sectors. Most downstream customers are maintaining contract-based essential procurement, leading to a steady decline in port pickup volumes. Overall, it is projected that styrene inventories at Jiangsu ports will see a slight accumulation.
