Price trend

According to the SunSirs Commodity Market Analysis System, the domestic butadiene market was primarily range-bound this cycle. From September 8 to 15, 2025, the price of butadiene decreased by 2.06% from 9,400 RMB/ton to 9,206 RMB/ton. Last week, the domestic butadiene market was weaker. On the supply side, some plants were shut down, leading to a slight decline in domestic production. Port arrivals have been low recently, leaving port inventories at low levels, providing a slight boost to the supply side. On the demand side, the downstream synthetic rubber market was weak, with low market participation and weak purchasing intentions. Lack of demand support has led to a generally weaker butadiene market. As of September 15, the delivered price in Shandong was between 9,350 and 9,450 RMB/ton, down approximately 200 RMB/ton from the same period the previous week.

Market outlook

Domestic butadiene supply has seen some support recently, but downstream demand has not significantly increased. Market expectations were generally weaker, the overall market was weaker under the purchase intention of just-needed. The butadiene market is expected to fluctuate and weaken in the short term. However, there is room for further growth before the holiday due to the pre-holiday stocking demand.
