II. Sample Inventory Trends and Product Price Comparison

For the period from October 12 to October 18 (a total of 7 days), barring any sudden market disruptions, incoming shipments of styrene are expected to increase. Meanwhile, downstream demand has rebounded following the National Day holiday, leading to a corresponding rise in port pickup volumes. Based on an assessment of both supply and demand factors, Jiangsu styrene port inventories are projected to experience a slight accumulation during this period.

III. Sample Inventory Trends and Product Price Comparison

During the period from October 8 to October 11 (a total of 4 days), domestic vessel arrivals decreased. The total volume of styrene arriving via vessels, pipelines, and trucks into Jiangsu's social inventory was 12,000 tons, compared to 11,900 tons over the same four-day period last year. Pickup volumes for this cycle were 19,700 tons, versus 17,300 tons in the same period last year.

As of the morning of October 12, the total sample inventory of styrene at Jiangsu ports saw a slight decrease. However, the figure remains 79.85% lower than the same period last year. Current port inventory data indicates that stocks are 132.94% higher than the lowest point recorded since 2022, but 84.62% lower than the highest point since 2022. In terms of current levels, inventory sits within the low range for the same period over the past five years (2021–2025).
