During the current statistical cycle (July 23-29, 2026), domestic butadiene inventories declined, with total sample inventories down 7.71% from the previous cycle. Sample producer inventories fell 11.25% week on week; as some downstream enterprises continued procuring essential feedstocks to meet contract deliveries, producer inventories edged lower. Sample port inventories decreased 6.15% week on week, as import arrivals during the week provided limited replenishment and downstream feedstock consumption proceeded normally, leaving port inventories slightly lower.
Sample description: Butadiene producer inventory data cover PetroChina, Sinopec, and other producers, accounting for 45% of total domestic butadiene production capacity. The producer inventory sample comprises 19 producers.
Butadiene port inventory data are based on samples in East China, with commercial tank farms accounting for 100% of the sample coverage. The port inventory sample comprises 9 tank farms, including 4 commercial tank farms and 5 enterprise feedstock tank farms.
Terminology: China's butadiene producer and sample tank farm inventories refer to physical inventory, i.e., the actual quantity of product stored in warehouses at a given point in time.
Statistical scope: Chempricehub Information collects China butadiene inventory data as of Wednesday of the current week and releases the data by 17:00 every Thursday (working day).
