II. Comparison of Sample Inventory Trends and Product Prices

From August 31 to September 6 (7 days), on the information front, and barring unexpected disruptions, styrene vessel arrivals at ports are expected to increase during this period. Downstream demand remains stable, with expectations of a modest improvement, and port offtake volumes are expected to remain steady. On balance, port replenishment supply is expected to be slightly higher than offtake, and moderate inventory accumulation is expected at Jiangsu styrene ports next week.

During the 7 days from August 24 to August 30, domestic trade vessel arrivals increased notably. The total volume of styrene arriving at Jiangsu public social warehouses via vessel, pipeline, and truck unloading was 3.325 ten-thousand tonnes, compared with 5.94 ten-thousand tonnes in the same period last year (7 days). During this period, offtake was 3.925 ten-thousand tonnes, versus 4.190 ten-thousand tonnes in the same period last year.

As of the morning of August 31, the total sample inventory of styrene at Jiangsu ports continued to decline, down 79.75% year-on-year.
