II. Sample Inventory Trends vs. Product Prices

From October 26 to November 1 (a total of 7 days), domestic vessel arrivals increased slightly during this period. The total volume of styrene arriving via vessels, pipeline transport, and truck unloading into social inventories in Jiangsu was 34,950 tons, compared to 34,300 tons over the same 7-day period last year. Deliveries during this period amounted to 28,950 tons, compared to 48,000 tons delivered during the same period last year.

III. Forecast for Next Period

For the period from November 2 to November 8 (7 days), overall domestic styrene operating rates are expected to remain stable, with no clear signs of upward movement. At the beginning of the week, domestic shipment volumes declined slightly within a narrow range, suggesting that overall arrival levels may also see a minor decrease. On the demand side, downstream industries are maintaining steady operations based on rigid demand, leaving limited room for further growth. Considering both supply and demand dynamics, along with the current port inventory base, it is projected that fluctuations in Jiangsu styrene port inventories will be limited this period, with a possibility of slight destocking.
