Weekly Data Statistics on Butadiene Inventory in China (November 5–11, 2026)

During the current period (November 5–11, 2026), domestic butadiene inventories saw a slight increase, with total sample inventory rising by 1.23% compared to the previous week. Specifically, inventory at sampled enterprises increased by 1.63% week-on-week. Strong downstream resistance to high raw material prices and generally subdued market trading activity contributed to this modest buildup in enterprise inventories. Meanwhile, port inventory among samples rose by 0.95% from the previous week, driven by a slight replenishment of domestic supply during the week and normal consumption of raw materials by downstream users.

Sample Description:

• Butadiene Producer Inventory: This metric covers inventories held by Sinopec, PetroChina, and other producers, representing 45% of total domestic butadiene production capacity. The sample comprises 19 enterprises.
• Butadiene Port Inventory: This metric reflects sample inventories in the East China region, where commercial tank farms account for 100% of the sampled capacity. The sample includes 9 tank farm sites: 4 commercial tank farms and 5 enterprise-owned raw material tank farms.
