During this period (August 13-19, 2026), domestic butadiene inventories increased, with total sample inventories rising 1.09% from the previous period. Specifically, sample enterprise inventories grew 14.70% week-on-week. As market prices moved higher, sellers grew reluctant to sell, leading to a slight build-up in enterprise inventories. Sample port inventories, however, declined 4.85% week-on-week. With limited import arrivals at ports during the week and downstream raw material consumption proceeding at a normal pace, port inventories decreased slightly.
Sample description: Butadiene producer inventories cover inventories held by PetroChina, Sinopec, and other enterprises, representing 45% of total domestic butadiene production capacity. The producer sample inventory comprises 19 enterprise samples.
Butadiene port inventories refer to sample inventories in the East China region, with commercial tank farms accounting for 100% of the sample. The port sample inventory includes 9 tank farm samples, consisting of 4 commercial tank farms and 5 enterprise feedstock tank farms.
Terminology: China's butadiene producer and sample tank farm inventories are physical inventory quantities, referring to the actual quantity of products stored in warehouses at a given point in time.
Statistical scope: The statistical period for Chempricehub's China butadiene inventory data is as of Wednesday of the current week, with data released before 17:00 every Thursday on working days.
