II. Comparison of Sample Inventory Trends with Product Prices

For the seven-day period from September 7 to September 13, based on available market information, unless there are unexpected disruptions, styrene vessel arrivals during this period are expected to increase slightly. Downstream demand remains stable, and port withdrawals are expected to stay steady. Overall, replenishment arrivals are expected to be slightly higher than withdrawals, so Jiangsu styrene port inventory is expected to accumulate modestly next week.

III. Comparison of Sample Inventory Trends with Product Prices

For the seven-day period from August 31 to September 6, domestic trade vessel arrivals weakened. The total volume received into Jiangsu public styrene storage — via vessel, pipeline transfer, and truck unloading — was 23,000 metric tons, versus 18,000 metric tons in the same period last year (7 days). Withdrawals over this period were 25,500 metric tons, versus 38,000 metric tons in the same period last year.

As of the morning of September 7, the total sample inventory at Jiangsu styrene ports continued to decline, down 78.87% year-on-year. Based on current port inventory data, the current inventory is 119.41% higher than the low point since 2022 and 85.51% lower than the high point since 2022. Accordingly, the current inventory is in the low range for the corresponding period over the past five years (2021–2025).
