According to the Commodity Market Analysis System of Shengyi Society, the domestic butadiene market will experience range bound fluctuations in November 2025. From November 1st to 30th, the domestic butadiene market price decreased from 7516.67 yuan/ton to 7050 yuan/ton, with a price drop of 6.21% during the period.
Early October: At the beginning of the month, the domestic butadiene market was weak and experienced a wide decline. As prices continued to fall, it attracted some downstream buyers to replenish their inventory at low prices, leading to an improvement in the trading atmosphere of the spot market and a slight rebound in spot market prices. However, due to weak downstream terminal demand and bearish supply performance, the overall butadiene market remained weak under the dual negative impact.
Late period: After entering late period, the butadiene market fluctuated in a range of first rising and then falling. In terms of supply, the overall supply has remained relatively loose in the near future. With the rise in prices, the enthusiasm for downstream market entry has significantly weakened. In addition, the recent weak trend of the synthetic rubber market has weakened the trend of the butadiene market.
Cost wise: According to the Commodity Market Analysis System of Shengyi Society, the butadiene market fluctuated in a range of first rising and then falling after entering the latter half of the year. In terms of supply, the overall supply has remained relatively loose in the near future. With the increase in prices, the enthusiasm for downstream market entry has significantly weakened. In addition, the recent trend of the synthetic rubber market has been weak, and the trend of the butadiene market has weakened. As of the 26th, the settlement price of the January WTI crude oil futures contract in the United States was $58.65 per barrel. The settlement price of Brent crude oil futures for February is $62.54 per barrel.
Supply side: As of November 27th, the listed price of butadiene for various sales companies of Sinopec is 7100 yuan/ton, a decrease of 800 yuan/ton compared to the same period last month.
Demand side: The domestic market for butadiene rubber in this cycle first rose and then fell, with an overall small increase. On the one hand, the price of raw material butadiene has risen slightly at a low level, and the cost support for butadiene rubber is relatively weak; Part of the pre maintenance equipment has restarted operation, and the production of butadiene rubber has slightly increased; The downstream tire production is basically stable, and there is a strong demand for support for butadiene rubber. The basic operation of butadiene rubber is weak. According to the Commodity Market Analysis System of Shengyi Society, as of November 24th, the market situation of Shunding rubber in the northwest region has slightly improved. At present, the mainstream prices for butadiene rubber in Sichuan, Dushanzi, and Lande are 10500-10700 yuan/ton.
Market forecast: The butadiene market has rebounded in the early stage, with market prices tentatively rising, and downstream market enthusiasm significantly declining. Currently, the trading situation in the spot market is average. Overall, the current supply of butadiene is relatively loose, downstream demand is weak, and the trend of the synthetic rubber market is weak, lacking favorable support. It is expected that the butadiene market will continue to be weak and volatile, with a focus on downstream procurement demand.

Cost stabilization supported by demand, phthalic anhydride prices fluctuated and fell this week, plasticizer costs decreased, and there is still downward pressure on plasticizer DOP this week.
Future expectations
According to the data analyst of Shengyi Society’s plasticizer products, in terms of cost, the price of isooctanol has risen, while the price of phthalic anhydride has fluctuated and fallen. The downward pressure on the cost of plasticizer DOP still exists, and the upward support is increasing; In terms of supply, the operating rate of plasticizer enterprises has slightly increased, the production of plasticizers has increased, and the supply of plasticizers is sufficient. In the future, with sufficient supply and rising costs, it is expected that the price of plasticizer DOP will fluctuate and rise.

This week, the domestic phenol market saw a narrow upward trend before weakening. Sinopec East China’s listed price is 6300 yuan/ton. According to data monitored by Shengyi Society, from the perspective of the East China market, the domestic phenol market price was 6295 yuan/ton on November 1st, and 6307 yuan/ton on November 21st, a decrease of 0.2%.
This week, the operating rate of Fuyu Petrochemical’s phenol ketone unit has gradually increased, and the first phase of Zhejiang Petrochemical’s unit has restarted and increased its load.

In the first half of the week, the market was boosted by supply support, and on Tuesday, the main factories in Shandong region raised their listing prices. From the demand side, participation is limited, downstream offers are low, cautious pursuit of price increases, downstream demand for bisphenol A urgently needs to follow up, and other downstream changes are not significant. The market has weakened again due to sluggish demand.
Business Society predicts that the phenol market will experience narrow fluctuations next week. Currently, the cost of pure benzene is relatively strong, which may lead to a slight increase in phenol prices in the short term. As the supply and shipment pressure approaches the end of the month, there is little intention to offer discounts. However, considering the sluggish buyer market, it is difficult for the market to see a significant increase. It is expected that the phenol market will experience narrow fluctuations and adjustments next week.

This week (11.10-14), domestic liquid ammonia continued its upward trend from last week. According to the Commodity Market Analysis System of Shengyi Society, the weekly increase of liquid ammonia in Shandong region was 3.33%, indicating a strong upward trend. The main reason for the continued rise of domestic liquid ammonia is due to the background of environmental protection and production restrictions in the north, coupled with the favorable supply of equipment maintenance in some areas and the linkage factors of downstream demand improvement. At present, the mainstream price of liquid ammonia in Shandong region is between 2400-2600 yuan/ton.

In terms of supply, the supply-demand pattern continued to improve this week, with tight supply performance. Some provinces in the northern main production areas have implemented environmental protection production restrictions, resulting in a decrease in enterprise operating rates. In addition, some facilities are still under maintenance, leading to a decrease in supply. In addition, due to the influence of Hebei, Shanxi and other regions, prices in the northwest and Inner Mongolia have shown a linked upward trend, while the production of ammonia enterprises in the southwest has declined, and equipment has been operating at reduced loads, resulting in a slight rebound in prices. This week, manufacturers in Shandong region raised prices within the range of 100-200 yuan/ton, with varying degrees of price increases from the beginning of the week to the weekend. The market performance is in short supply.
On the demand side, there has been a slight improvement in downstream demand, with the operating rate of compound fertilizers continuing to improve, and the demand for urea remaining strong and demanding; Especially with the strong upward trend of downstream nitric acid, the operating rate of acid enterprises has increased, and the demand for liquid ammonia has significantly increased. Overall, in terms of agriculture, there has been a significant increase in demand for agricultural procurement, while industrial demand remains strong with a moderate upward trend. Downstream urea also continues to rebound, with a 0.46% increase in urea prices this week according to the Commodity Analysis System of Shengyi Society. Terminal delivery capacity has strengthened, and many purchases are made at low prices.
Market forecast:
Business analysts believe that the rise in liquid ammonia prices this week is mainly due to favorable conditions from the supply side. However, with the expectation of resuming work on northern maintenance facilities next week, the tight supply situation may ease in the later stage, and it is expected that the space for liquid ammonia prices to rise may be limited.
