During the reporting period (October 22–28, 2026), domestic butadiene inventories increased, with total sample inventory rising by 3.31% compared to the previous week. Specifically, inventory at sample enterprises decreased by 4.25% week-on-week, as several domestic plants underwent scheduled maintenance shutdowns while downstream users maintained steady procurement based on essential demand. In contrast, port inventory among sample facilities rose by 10.29% from the prior week, driven by the arrival of imported cargoes during the period, which offset normal consumption by downstream raw material users.
Sample Description:
The butadiene producer inventory data covers stocks held by PetroChina, Sinopec, and other producers, representing approximately 45% of total domestic butadiene production capacity. The sample includes 19 producer enterprises.
Port inventory data reflects sample stock levels in East China, with commercial tank farms accounting for 100% of the coverage. This sample comprises 9 tank farm sites, including 4 commercial tank farms and 5 enterprise-owned feedstock tank farms.
Definition:
Inventory figures for Chinese butadiene producers and sample tank farms represent physical stock levels, defined as the actual quantity of product present in storage facilities at a specific point in time.
