Several factors lie behind the rise, according to Claight market monitoring. Maintenance shutdowns at major domestic steam crackers including Qilu and TSRC reduced spot supply in early September. Sinopec also raised ex-factory butadiene prices by 600 to 700 RMB/ton on September 1, as reported by ECHEMI.
Supply tightness extended to trade and stocks. Mysteel reported on 2026-09-15 that Middle East tensions had reduced butadiene flows from Japan and South Korea to China. The same source recorded that China butadiene port inventory plunged 27.48% to 19,000 tonnes as of September 10.
