Price trend 

According to the SunSirs' commodity market analysis system, the domestic 1,3-butadiene market fluctuated upwards during this period. From November 17th to November 24th, 2025, the price of 1,3-butadiene rose from 6,966.67 RMB/ton to 7,066.67 RMB/ton, an increase of 1.44%. This period saw the domestic 1,3-butadiene market initially rise and then fall, with an overall upward trend. Recently, the 1,3-butadiene market was relatively strong. From a supply perspective, the overall supply remained relatively ample. However, as prices rose, downstream enthusiasm for entering the market weakened significantly. Coupled with the recent weakness in the synthetic rubber market, the 1,3-butadiene market had weakened.

Market Analysis

From a cost perspective: According to data from the SunSirs' commodity market analysis system, as of November 21st, the settlement price of the January contract for US WTI crude oil futures was $58.06 per barrel. The settlement price of the February contract for Brent crude oil futures was $61.94 per barrel. During this period, OPEC+ announced a new round of production increases, but the market remained concerned about the long-term risk of oversupply. 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.

Supply side: Sinopec's sales companies were maintaining a listed price of 7,200 RMB/ton for 1,3-butadiene.

Shenghong Refining & Chemical's 200,000-ton/year 1,3-butadiene unit was operating normally, with prices reduced by 200 RMB/ton to 7,100 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 7,100 RMB/ton.

Satellite Chemical's Lianyungang Petrochemical 90,000-ton/year 1,3-butadiene unit was operating normally, with prices reduced by 200 RMB/ton to 7,100 RMB/ton.

On the demand side: According to the commodity market analysis system of SunSirs, as of November 19th, the price of styrene-1,3-butadiene rubber (SBR) in the East China market was 11,050 RMB/ton, a decrease of 2.07% from 11,283 RMB/ton at the beginning of the month, and an increase of 4.25% from the low point of 10,600 RMB/ton during the cycle. On the one hand, raw material support was weak. On the other hand, downstream tire production was unstable, providing some support for the rigid demand for SBR; SBR production had increased slightly, but the fundamentals of SBR were weak, and the market was experiencing weak fluctuations. As of November 21st, the mainstream market price for SBR 1502 in Fushun, Jilin Chemical, Yangzi, and Qilu in East China was around 10,950-11,200 RMB/ton.

Market Outlook:

The 1,3-butadiene market saw a continuous upward trend in the previous period, but downstream enthusiasm for entering the market declined significantly, resulting in generally weak trading in the spot market. Overall, the 1,3-butadiene supply was relatively ample, while downstream demand was weak. Lacking positive support, the 1,3-butadiene market is expected to continue to fluctate and weaken, with a focus on downstream procurement demand.
