According to the Commodity Market Analysis System of Shengyi Society, from March 10th to 14th, the domestic aggregated MDI market experienced a weak decline, with an average price of 17466 yuan/ton at the beginning of the week and 17400 yuan/ton at the end of the week, a decrease of 0.38% during the period and a year-on-year increase of 3.57%. The domestic MDI aggregation market did not see any improvement in transactions within the week, and there is a strong willingness to ship at low prices. Downstream cautious entry into the market, limited news boost, and the market remains weak.

On the supply side, the domestic Fujian plant operates at low negative loads, while other plants operate smoothly. The 70000 ton/year MDI plant of Japan’s Covestro will begin maintenance in early March and is expected to be serviced around January. Huntsman’s 500000 ton MDI plant located in North America is scheduled to be shut down for maintenance starting from early March, lasting for one month.

On the cost side, raw material pure benzene: The price of pure benzene has continued to decline, and the operating rate of pure benzene has rebounded. The inventory of pure benzene in ports continues to decrease, and downstream production of caprolactam is at a high level. The demand for pure benzene is relatively strong, and currently it is still mainly supported by costs. Raw material aniline: Aniline has fallen, with a mainstream price of 8700-8850 yuan/ton. The overall shipment of aniline factory is not smooth, with accumulated inventory and insufficient confidence in the field.

On the demand side, downstream demand follow-up is average, with a focus on essential needs. Export orders are still acceptable, but demand needs further improvement.

Future forecast: The current aggregated MDI market is running weakly, supported by overseas maintenance news, with suppliers controlling their inventory and digesting it, waiting for demand to rebound.

According to the Commodity Market Analysis System of Shengyi Society, the domestic adipic acid market has been weak and declining since March. On March 1st, the average market price of adipic acid was 8366 yuan/ton. On March 14th, the average market price of adipic acid in China was 7833 yuan/ton, a decrease of 7.11%.

Loose supply leads to weak decline in domestic adipic acid market

Since March, the prices of pure benzene and cyclohexanone raw materials for adipic acid have continued to decline, with poor demand from the terminal industry and oversupply in the adipic acid market. The prices of adipic acid manufacturers and traders have continued to decline, resulting in a decrease in market trading volume and mediocre sales. The average market price of adipic acid has dropped to 7700-7900 yuan/ton, with an overall decrease of 200-300 yuan/ton.

An analyst from Shengyi Society believes that in late March, due to poor demand in the terminal industry and a weak decline in raw material prices, the adipic acid market will continue to decline in the future.

According to the Commodity Market Analysis System of Shengyi Society, the aggregated MDI market has recently experienced a high decline. The mainstream price for Shanghai goods (44V20, M20S, 5005) is 17600-18800 yuan/ton, while the mainstream price for domestic goods (PM200) is 17900-18100 yuan/ton. The Fujian plant is on the brink of shutdown, but the market supply is still sufficient. Downstream demand is average, while upstream demand is more proactive, resulting in reduced prices for delivery. There is no obvious positive boost in the market, and it is expected that the aggregated MDI market will operate weakly in the short term.

According to the monitoring of the commodity market analysis system of Shengyi Society, the price of activated carbon at the beginning of the week was 11956 yuan/ton, and the price of activated carbon at the end of the week was 11966/ton, with a price increase of 0.08%.

Domestic activated carbon manufacturers have seen some price increases this week, while most have remained stable. The ex factory price of activated carbon for coconut shell water purification in East China is between 9500-12500 yuan/ton, and market transactions have accelerated. Industry insiders are optimistic about the future and are focusing on market transactions.

The shipment of coconut shell charcoal for applications such as gold extraction, water purification, and filter cartridges has accelerated, especially for gold charcoal, which has received more inquiries from the African market; The shipment of fruit shell charcoal is smooth. There is a recent rebound trend in imported carbide materials, so pay more attention to the transaction situation.

Prediction: The trading atmosphere in the activated carbon market is active, and it is expected that the price of activated carbon will mainly fluctuate with a strong trend in the short term.

(Note: The cycle refers to the period from September 1, 2011 to present)

2、 Market analysis

According to the commodity analysis system of Shengyi Society, the market for soda ash this month first fell and then rose. The utilization rate of soda ash production capacity remained at a high level during the month, and the market supply was sufficient. The sales pressure of spot soda ash factories was high, while downstream glass fluctuated narrowly and mainly consumed inventory, resulting in limited demand for soda ash and overall weak soda ash prices. At the end of the month, affected by the news of soda ash maintenance, the market supply expectation decreased, and the intention of factories to rise increased, resulting in a strong increase in soda ash prices.

As of February 28, 2025, the mainstream market price of light soda ash in East China is around 1480-1550 yuan/ton; The mainstream market price of light soda ash in Central China is around 1400-1500 yuan/ton; The mainstream market price of light soda ash in North China is around 1480-1570 yuan/ton.

On the demand side: According to the commodity analysis system of Business Society, the price trend of glass has fluctuated and risen this month. The average market price of glass at the beginning of the month was 16.20 yuan/square meter, and the average market price at the end of the month was 16.40 yuan/square meter, an increase of 1.23%. The capacity utilization rate of the glass market has decreased, and the spot market is fluctuating at a high level. Downstream market entry follows suit according to demand, and the trading atmosphere in the market is still acceptable. The glass inventory has increased, and the price market is consolidating.

According to the price monitoring of Shengyi Society, the price comparison index of Shengyi Society’s soda ash and glass products on February 28th was 81.65, an increase of 4.69 points from yesterday, a decrease of 27.34% from the highest point of 112.37 points during the cycle (October 6, 2023), and an increase of 10.79% from the lowest point of 73.70 points on February 16, 2025. (Note: Cycle refers to January 1, 2012 to present)

Market forecast: According to the commodity analysis system of Shengyi Society, there are maintenance plans for some domestic soda ash plants, and the expected capacity utilization rate is decreasing. The mentality of spot soda ash plants is optimistic. Recently, the price of light soda ash has risen strongly, and the overall demand for soda ash in the downstream is limited. The supply and demand game in the market is expected to cause fluctuations in soda ash prices in the later stage, depending on downstream market demand.

The butadiene rubber market experienced a significant decline in February. According to the Commodity Market Analysis System of Shengyi Society, as of February 27th, the market price of butadiene rubber in East China was 14030 yuan/ton, a decrease of 6.47% from 15000 yuan/ton at the beginning of February. The price of raw material butadiene has dropped significantly, and the cost center of butadiene rubber has shifted downwards; The production of Shunding rubber has slightly decreased compared to the end of January, and the pressure on the supply side has slightly decreased; In mid to late February, downstream tire production increased significantly, providing strong support for the demand for butadiene rubber. As of February 27th, the mainstream price in East China is 13850-14250 yuan/ton.

Since February, the price of butadiene has significantly decreased, and the cost center of butadiene rubber has shifted downwards. According to the Commodity Market Analysis System of Shengyi Society, as of February 27th, the price of butadiene was 11087 yuan/ton, a decrease of 12.44% from 12662 yuan/ton at the beginning of February.

In February, the domestic production of butadiene rubber plants remained at around 6.20%, and the supply pressure slightly decreased compared to January.

Demand side: Downstream tire production will increase after the holiday, mainly supporting the demand for butadiene rubber market. As of February 20th, the operating load of semi steel tires in domestic tire enterprises is around 8.0%; The construction of all steel tires by tire enterprises in Shandong region has slightly increased to around 6.7% of the load.

Market forecast: From a fundamental perspective, analysts from Shengyi Society believe that after a sharp drop in butadiene prices in the short term, it will consolidate weakly, and the cost support of butadiene rubber will continue to be weak; Post holiday downstream construction will increase; The production of butadiene rubber remains at a low level, and overall, it is expected that the butadiene rubber market will fluctuate and consolidate in the later stage.

According to the Commodity Market Analysis System of Shengyi Society, as of February 26, 2025, the reference price of n-butanol in Shandong Province, China is 7133 yuan/ton. Compared with February 1 (reference price of n-butanol is 7066 yuan/ton), the price has increased by 77 yuan/ton, an increase of 0.94%.

In February, the overall n-butanol market in Shandong region of China showed a trend of “rising first and then falling”. In early February, with the return of the Spring Festival holiday, the n-butanol market in Shandong Province experienced an upward trend. As of February 15th, the reference price for n-butanol market in Shandong was 7300-7400 yuan/ton, with a 3.63% increase in the first half of the year.

In late February, the downstream stage of n-butanol stocking was basically completed, and the focus of n-butanol market negotiations shifted downwards. As of February 26th, the market price of n-butanol in Shandong region is around 7100-7200 yuan/ton, with a decline of 2.59% in the latter half of the year.

Analysis of Market Factors

In terms of supply and demand: In early February, after the holiday, some factories in the n-butanol field are expected to start production later, resulting in overall tight supply and lower supply pressure. Downstream demand for n-butanol is gradually recovering, and downstream demand is entering a stage of stocking. With the support of supply and demand, the market price of n-butanol is constantly moving upwards. The downstream stage stocking of n-butanol has basically ended, and the demand side has weakened, providing loose support for n-butanol. The overall supply side of n-butanol is under certain pressure, and some factories have shifted the focus of n-butanol market negotiations to ensure low inventory and make concessions for shipment.

In terms of cost: In February, the upstream propylene market fluctuated, but after the Spring Festival, the rise in the propylene market provided stronger cost support for n-butanol. Subsequently, the downward market trend weakened the support for n-butanol. As of February 25th, the reference price of propylene was 6810.75 yuan/ton, a decrease of 0.18% compared to February 1st (6823.25 yuan/ton).

Market analysis in the future

At present, the overall operation of the n-butanol market is being consolidated, and the overall negotiation atmosphere in the market is relatively low-end. n-butanol factories are mostly stabilizing prices and shipping, while downstream users are mainly purchasing for essential needs at low prices. The n-butanol data analyst from Shengyi Society predicts that in the short term, the domestic n-butanol market will mainly adjust its operation within a narrow range, and specific changes in supply and demand news need to be closely monitored.

Product Name: Pure Benzene

Latest price: On February 25th, the average market price was 7759.67 yuan/ton, a decrease of 0.43% from the previous trading day.

Analysis: The price of pure benzene in the domestic market has fallen today. Shandong’s local refining enterprises continue to offer discounts on market prices, while the spot price of pure benzene in East China is consolidating weakly. International crude oil futures closed higher, while the price of pure benzene fell in the foreign market. Today, the styrene futures market weakened. Overall, the buying potential in the pure benzene market is still acceptable at low levels. It is expected that the pure benzene market will consolidate weakly in the short term, and actual transactions are subject to negotiation.

According to the Commodity Market Analysis System of Shengyi Society, as of the 21st, the price of ethyl acetate was 5623.33 yuan/ton, a decrease of 0.30% compared to the price of 5640.00 yuan/ton on February 15th, and a decrease of 0.12% from the beginning of the month. The utilization rate of supply side production capacity has increased, downstream demand performance is insufficient, the market supply is strong and demand is weak, and the ethyl acetate market is consolidating and declining.

This week, the operating rate of domestic ethyl acetate plants has increased, the supply of market goods has increased, the prices of raw materials continue to rise, and cost pressure continues to increase. However, downstream production of ethyl acetate is not high, and demand performance is weak. In order to maintain shipments, enterprises have lowered their prices for ethyl acetate, resulting in poor on-site trading and weak operation of the ethyl acetate market.

In the future, some enterprises plan to increase the load of their ethyl acetate facilities, and the utilization rate of on-site production capacity will continue to increase. The pressure on market supply of goods will increase, and downstream factories will not start operating enough. Market demand is limited, and it is expected that the price of ethyl acetate will continue to be weak in the short term. Specific attention should be paid to changes in supplier facilities and downstream follow-up situations.
