During the current period (September 10–16, 2026), domestic butadiene inventories increased, with total sample inventory rising by 13.42% week-on-week. Specifically, sample enterprise inventory decreased slightly by 0.32% compared to the previous week. Downstream demand showed no significant improvement, and procurement intentions for raw materials remained weak, resulting in minimal changes in enterprise inventory levels. Meanwhile, sample port inventory surged by 24.74% week-on-week. Although limited imported butadiene cargoes arrived during the week, domestic supply arrivals replenished stocks. Additionally, downstream consumption of raw materials slowed slightly, contributing to the increase in port inventory.
Sample Description:
