According to the commodity analysis system of Shengyi Society, the overall domestic market for maleic anhydride rose in March. As of March 31st, the average quoted price of maleic anhydride was 6790.00 yuan/ton (including tax), an increase of 3.19% from 6580.00 yuan/ton on March 1st.

Supply side: In March, the spot supply of maleic anhydride in the market was tight, and downstream unsaturated resin manufacturers of maleic anhydride mainly maintained stable production. Due to the rise in raw material prices, unsaturated resins slightly increased, and the replenishment of maleic anhydride was mainly for urgent needs. At present, the increase in spot supply in the maleic anhydride market is limited. As of March 31st, the factory price of solid anhydride in Shandong region is around 6700 yuan/ton, and the factory price of liquid anhydride is around 6400 yuan/ton.
Upstream: The market price of pure benzene has fallen. Since the beginning of the month, the price of pure benzene has almost been declining one by one. On March 1st, the price was 7518 yuan/ton; On March 31st, the price was 6634.67 yuan/ton, a decrease of 11.57% from the beginning of the month. In the short term, the market price of pure benzene continued to fluctuate and consolidate.
In March, the international crude oil market fluctuated downwards, and the price of n-butane fluctuated upwards. As of March 31st, the price in Shandong was around 5300-5350 yuan/ton.
Downstream: Currently, unsaturated resin companies are mainly operating steadily, but due to the impact of rising raw material prices and subsequent declines, the unsaturated resin market remains stable, and there is a strong wait-and-see sentiment in the market.
The analyst of Shengyi Society’s maleic anhydride products believes that the recent replenishment of downstream resin demand for maleic anhydride has ended, and new order signings are limited; At present, the prices of the main factories producing maleic anhydride have fallen, and it is expected that the maleic anhydride market will mainly consolidate weakly in the near future.

According to the Commodity Market Analysis System of Shengyi Society, the domestic ethanol market was weak and volatile in March. From March 1st to 31st, the average price of domestic ethanol producers decreased from 5275 yuan/ton to 5262 yuan/ton, with a price drop of 0.24% during the period and a year-on-year price drop of 14.43%.
In the first half of the month, the domestic edible ethanol market price remained stable with some increase, but the upward trend slowed down. The price of raw material corn continues to operate strongly, and the production cost of corn ethanol is under pressure. Holders have a strong mentality of supporting prices and a strong focus.

In mid month, the domestic edible ethanol market experienced narrow fluctuations in prices, with a balanced supply and demand performance. In some regions, with strong support from corn on the cost side, production companies have raised their quotations.
At the end of the month, the domestic edible ethanol market prices slightly adjusted, and the raw material corn prices were narrow and strong, with strong cost support. After the price rose, it remained stable. The downstream market has a strong wait-and-see attitude, with a focus on stocking up for urgent needs, resulting in lukewarm transactions.
As the end of the month approaches, the domestic edible ethanol market prices have slightly declined, and the price of raw material corn is running weakly, putting pressure on production costs and increasing the willingness to raise prices; Downstream customized procurement based on demand, with cargo holders accompanying the shipment, resulting in an average transaction atmosphere.
On the cost side, in the first half of the month, the price of raw material corn remained stable but slightly strong, and the cost side provided some support for alcohol prices. With the boost of favorable costs, enterprises have a strong mentality of supporting prices. At the end of the month, the demand in the corn market is currently slightly average, and the corn market prices are running weakly. The cost support of ethanol is still acceptable.
Supply side, stable operation of supply side. The maintenance of the biological fermentation ethanol plant is concentrated in April, and the on-site supply side is stable and organized. The stable operation of cassava corn ethanol supply side. Coal to ethanol production: Anhui Carbon Xin and Hengxin facilities are temporarily shut down, while other facilities are producing steadily. There are unlikely to be major favorable factors in the supply of ethanol.
On the demand side, from the demand side, Baijiu consumption support is limited; The operating rates of downstream methyl ethyl carbonate and ethyl acetate do not change significantly, and their consumption of ethanol remains stable; Other downstream chemical industries are accompanied by regular procurement, with a focus on stocking up for essential needs, resulting in limited demand boost. The short-term demand for ethanol has a moderate impact.
In the future, the price of raw corn is expected to fluctuate and stabilize, putting pressure on production costs; The mentality of the demand side is cautious, with a focus on purchasing essential needs. Business Society’s ethanol analyst predicts that the domestic ethanol market will consolidate and operate in the short term.

In March 2025, the market trend of the main raw material for viscose staple fiber dissolution pulp was weak, and the demand in the terminal market was sluggish. Downstream yarn factories mainly purchased according to demand, and the actual negotiation focus fluctuated and declined. The viscose staple fiber market operated weakly, and prices were slightly lowered.

According to the Commodity Market Analysis System of Shengyi Society, as of March 31st, the average market price of viscose staple fiber was 13600 yuan/ton, a decrease of 120 yuan/ton from the previous month, with a monthly decline of 0.87%.
The trend of the main raw material dissolution slurry market is downward
In March 2025, the upstream main raw material dissolution pulp market experienced a weak decline. As of March 31, the price of domestically produced dissolution pulp was around 7600 yuan/ton, the price of outer broad-leaved pulp was around 930 US dollars/ton, and the price of coniferous pulp was around 1030 US dollars/ton. The auxiliary liquid alkali market and sulfuric acid market continue to maintain stable prices. Overall, the upstream main raw material dissolution slurry market is trending downward, while the auxiliary liquid alkali market and sulfuric acid market continue to maintain stable prices. The price center of the raw material market has fallen, and the cost support of adhesive short fibers is weak.
Good supply and demand are hard to find
In March 2025, some adhesive short fiber parking and maintenance facilities in Jiangsu have not yet restarted, while some adhesive short fiber facilities in Shandong and Xinjiang have increased their operating loads, resulting in a gradual increase in on-site supply; Downstream yarn manufacturers are experiencing poor shipments, resulting in low enthusiasm for picking up adhesive short fibers. The overall inventory level of the adhesive short fiber market has increased narrowly, and the positive support from the supply side is limited.
The downstream cotton yarn market equipment has basically resumed normal operation, with little price change. As of March 31st, the price of 30S cotton yarn spun by ring spinning in Jiangsu region was around 17550 yuan/ton, a decrease of 75 yuan/ton from the beginning of the month. However, due to insufficient orders in the end market, the shipment situation of yarn factories is not ideal, and there is still a certain amount of raw material inventory and finished product inventory, resulting in a weak willingness to purchase adhesive short fibers, and it is difficult to find favorable support from the demand side.
Future forecast
From a cost perspective, the main material dissolution slurry market is dominated by consolidation; From the perspective of supply and demand, there are plans to increase the operating rate of some adhesive short fiber facilities in Jiangsu Province. The on-site supply may increase slightly, and the industry inventory may remain at a normal level. The downstream market or consumption of raw material inventory is the main focus, and there has been no significant improvement on the demand side. Overall, the market lacks good news to boost it. Business analysts predict that the domestic adhesive short fiber market will be mainly weak in the short term, with prices expected to be accepted at 13400-13600 yuan/ton.

Analysis: This week (3.24-28), the liquid ammonia market in Shandong region showed weak performance, with prices reversing last week’s upward trend and turnover declining. According to the Commodity Market Analysis System of Shengyi Society, the main production area of Shandong experienced a weekly decline of 5.43%. The main reason is that the supply has shifted from tight to loose, increasing supply pressure. The early maintenance equipment has gradually resumed, and the operating rate of manufacturers has increased. Coupled with the poor performance of the urea market, some manufacturers have switched to ammonia, which has further exacerbated the contradiction of oversupply in the ammonia market. From the beginning of the week to the weekend, some mainstream large factories in Shandong generally lowered their prices by 100-200 yuan/ton. Distributors mainly underreport shipments. And downstream procurement enthusiasm is not high, agricultural demand is still in the off-season, industrial demand remains rigid, and the overall demand side is bearish. At present, the mainstream quotation in Shandong region is 2500-2700 yuan/ton.

Prediction: The peak season for spring plowing has ended, agricultural demand has weakened, downstream procurement is more rational, market atmosphere is light, downstream operating rates have significantly decreased, and industrial demand is urgently following suit. However, the supply of liquid ammonia is relatively sufficient, and the pressure of supply and demand is prominent. It is expected that there is still room for ammonia prices to decline before the Qingming Festival.

This week, the price of bromine has been rising, with the price of bromine in Shandong region increasing. The mainstream market price is around 23000-24000 yuan/ton. Bromine inventory is tight, and although downstream flame retardant manufacturers have low operating rates, demand is active. Imported bromine has been delayed, and prices have risen. It is expected that prices will remain stable with some increase in the short term. In terms of raw materials, domestic sulfur prices have been running weakly, with an average market price of 2487.67 yuan/ton at the beginning of the week and 2434.33 yuan/ton over the weekend. The price has decreased by 2.14% and increased by 132.58% compared to the same period last year. Downstream demand is generally average.

Prediction: Bromine prices are expected to rise recently, while upstream sulfur prices are expected to remain weak. Bromine supply is tight, and downstream demand is good. However, the supply of imported bromine is slow. Overall, it is expected that bromine prices may continue to rise in the later period, depending on downstream market demand.

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.
