II. Sample Inventory Trend and Product Price Comparison (Outlook)

For the period of September 28 to October 7 (10 days), barring any sudden market disruptions, incoming styrene shipments to port are expected to increase slightly during this cycle. Additionally, with the National Day holiday approaching, downstream demand is trending weaker, and port delivery volumes are expected to stabilize or decline. Based on comprehensive analysis, Jiangsu styrene port inventories are projected to see a slight accumulation.

III. Sample Inventory Trend and Product Price Comparison (Historical Data)

During the 7-day period from September 21 to September 27, domestic arrivals weakened. Total styrene arrivals in Jiangsu social inventory—via ship discharge, pipeline transport, and truck unloading—amounted to 29,250 tons, compared to 38,300 tons for the same period last year (over 7 days). Deliveries during this cycle totaled 29,050 tons, versus 27,300 tons in the same period last year.

As of the morning of September 28, the total sample inventory at Jiangsu styrene ports increased slightly but remained 78.84% lower than the same period last year. Current port inventory data indicates that stock levels are 145.88% higher than the lowest point recorded since 2022, yet 83.77% lower than the highest point since 2022. In terms of historical comparison, current levels fall within the low range for the same period over the past five years (2021–2025).
