During the current period (July 30–August 5, 2026), domestic butadiene inventories increased, with total sample inventories up 7.95% from the previous period. Among these, sample enterprise inventories declined 2.74% week on week. Some enterprises slightly reduced operating rates, leading to a modest decline in supply, while downstream feedstock inventories were digested normally, causing enterprise inventories to edge lower. Sample port inventories rose 12.39% week on week, as some cargoes arrived at ports earlier during the week, lifting port inventory levels.
Sample description: Butadiene producer inventories include those of PetroChina, Sinopec, and other producers, accounting for 45% of the total production capacity of domestic butadiene producers. The producer inventory sample comprises 19 enterprises.
Butadiene port inventories are sample inventories in East China, with 100% sample coverage of commercial tank farms. The port inventory sample comprises 9 tank farms, including 4 commercial tank farms and 5 enterprise feedstock tank farms.
Terminology explanation: China’s butadiene producer and sample tank farm inventories are physical inventories, meaning the actual quantities of products stored in warehouses at a given point in time.
Statistical scope: Chempricehub Information’s China butadiene inventory statistics cover data as of Wednesday of the current week, with data released before 17:00 every Thursday (working day).
