Price trend

According to the commodity market analysis system of SunSirs, the domestic 1,3-butadiene market fluctuated within a range in November 2025. From November 1st to 30th, the domestic 1,3-butadiene market price decreased from 7,516.67 RMB/ton to 7,050 RMB/ton, a drop of 6.21% during the period.

Early November: At the beginning of the month, the domestic 1,3-butadiene market was weaker and experienced a wide decline. As prices continued to fall, some downstream buyers replenished their stocks at lower prices, which improved the trading atmosphere in the spot market and led to a slight recovery in spot market prices. However, due to persistently weak downstream demand and a bearish supply, the 1,3-butadiene market remained weak overall under the influence of these two negative factors.

Late November: After entering the latter part of the month, the 1,3-butadiene market fluctuated within a range, first rising and then falling. From the supply side, the overall supply remained relatively loose recently. As prices rose, downstream enthusiasm for entering the market weakened significantly. In addition, the synthetic rubber market was weak recently, and the 1,3-butadiene market also weakened.

Market Analysis

On the cost side:

Crude oil prices declined slightly. During this cycle, OPEC+ announced a new round of production increases, but market concerns about long-term oversupply risks persisted. Regional tensions eased somewhat, and weakening US demand, coupled with the drag from US tariffs on global economic and demand expectations, led to a slight decline in international oil prices. As of the 26th, the settlement price for the January contract of US WTI crude oil futures was $58.65 per barrel. The settlement price for the February contract of Brent crude oil futures was $62.54 per barrel.

Supply side:

As of November 27th, the listed price of 1,3-butadiene from Sinopec's various sales companies was 7,100 RMB/ton, a decrease of 800 RMB/ton compared to the same period last month.

Shenghong Refining & Chemical's 200,000-ton/year 1,3-butadiene unit was operating normally, with a price increase of 200 RMB/ton, at 7,050 RMB/ton.

Dongming Petrochemical's 50,000-ton/year 1,3-butadiene unit was operating normally, with 224 tons sold externally at a base price of 7,000 RMB/ton.

Satellite Chemical's Lianyungang Petrochemical's 90,000-ton/year 1,3-butadiene unit was operating normally, with a price increase of 100 RMB/ton, now at 7,000 RMB/ton.

On the demand side:

The domestic BR market saw a slight overall increase followed by a decline during this cycle. Firstly, 1,3-butadiene prices rose slightly from their low levels, weakening cost support for BR. Secondly, some previously shut-down plants restarted, leading to a slight increase in BR operating rates. Thirdly, downstream tire production remained relatively stable, providing support for BR demand. Overall, the fundamentals for BR remained weak. According to data from the SunSirs commodity market analysis system, as of November 24th, the BR market in Northwest China saw slight consolidation. As of November 24th, mainstream BR prices in Sichuan, Dushanzi, and Lande were quoted at 10,500-10,700 RMB/ton.

Market outlook

The 1,3-butadiene market had previously rebounded, with prices tentatively rising. However, downstream enthusiasm for entering the market declined significantly, and spot market trading was generally weak. Overall, the 1,3-butadiene supply was temporarily relatively ample, downstream demand was weak, and the synthetic rubber market was trending downwards. Lacking positive support, the 1,3-butadiene market is expected to fluctuate and weaken, with a focus on downstream procurement demand.
