During the current cycle (Aug 20–26, 2026), domestic butadiene inventory increased, while total sample inventory declined by 8.62% from the previous cycle. Among this, sample enterprise inventory fell 11.25% week-on-week; within the contract delivery period, downstream purchases based on rigid demand contributed to the decline in enterprise inventory. Sample port inventory decreased by 7.24% week-on-week; imported cargo arrivals remained limited during the week, and downstream raw material inventories were digested normally, resulting in the decline.
Sample description: Butadiene producer inventories include inventories of PetroChina, Sinopec, and other producers, representing 45% of total domestic butadiene production capacity. The butadiene producer inventory sample covers 19 producers.
Butadiene port inventory is based on sample inventories in East China, with commercial tank farm samples accounting for 100%. The butadiene port inventory sample covers 9 tank farms, including 4 commercial tank farms and 5 enterprise feedstock tank farms.
Terminology: Butadiene producer and sample tank farm inventories in China refer to physical inventory, i.e., the actual quantity of products stored in warehouses at a specific point in time.
Statistical basis: The China butadiene inventory statistics cycle of Chempricehub News is based on data as of Wednesday of the relevant week, with data released before 17:00 every Thursday on working days.
