2. Sample Inventory Trends vs. Product Price Comparison

From October 26 to November 1 (a total of 7 days), barring any sudden market disruptions, incoming vessel shipments of styrene are expected to increase slightly. Meanwhile, downstream demand is projected to remain stable, with limited room for further growth. Considering both supply and demand dynamics along with current port inventory levels, Jiangsu styrene port inventories are expected to see minimal changes, exhibiting narrow-range adjustments during this period.

3. Sample Inventory Trends vs. Product Price Comparison

During the week of October 19–25 (7 days), domestic arrivals decreased slightly. Total styrene inflows to Jiangsu social inventories via vessels, pipelines, and truck deliveries amounted to 22,500 tons, compared to 24,000 tons over the same 7-day period last year. Outflows during this period totaled 30,900 tons, versus 33,500 tons in the same period last year.

As of the morning of October 26, total sample inventory of styrene at Jiangsu ports declined. However, the figure remains 87.20% lower than the same period last year. Current port inventory data indicates that stock levels are 45.29% higher than the lowest point since 2022 but 90.41% lower than the peak since 2022. Based on current figures, inventory levels are within the low range observed during the same period over the past five years (2021–2025).
