According to the monitoring of the commodity market analysis system of Shengyi Society, the price of activated carbon at the beginning of the month was 11766 yuan/ton, and at the end of the month it was 12033/ton, with a price increase of 2.27%.

Domestic activated carbon manufacturers have seen some price increases this month, but most have remained stable. Henan Province, as the main production area, has relatively small price fluctuations. The ex factory price of activated carbon for coconut shell water purification is between 9500-13500 yuan/ton. Downstream sewage treatment plants, water plants, steel mills, and other chemical enterprises have increased their demand for carbon, and the demand fundamentals have slightly improved, which has slightly boosted the mentality of industry players.
In terms of imports: The price of imported coconut shell carbonization materials has increased, with the Philippines and Indonesia quoting a factory price of 6600-7000 yuan/ton for bulk materials including taxes, and a factory price of 7200-7300 yuan/ton for specification materials including taxes, which is slightly higher in some areas. The transaction volume of shell charcoal in gold extraction, water purification, filter and other applications is light, with more inquiries from African gold charcoal; The shipment of fruit shell charcoal is smooth.
Prediction: The transaction volume in the activated carbon market is accelerating, and it is expected that the price of activated carbon will mainly fluctuate with a strong trend in the short term.

1、 Price trend

According to the commodity analysis system of Shengyi Society, the price trend of soda ash remained stable this week. As of April 25th, the average market price of soda ash was 1400 yuan/ton, which was the same as the 1400 yuan/ton soda ash price on April 18th and a decrease of 2.37% from the beginning of the month.
2、 Market analysis
This week, the soda ash market has remained stable with small fluctuations, and prices in some regions have slightly decreased during the week. The operating rate of supply side equipment remains high, the market supply is sufficient, and enterprises maintain active shipment. Downstream consumption of inventory is the main factor, and the market buying sentiment is average. The demand for soda ash is limited, and on-site trading is weak. The overall transaction price of soda ash fluctuates slightly.
As of April 25th, the reference price for the soda ash market in East China is around 1280-1500 yuan/ton for light soda ash, which remains unchanged from last Friday; The reference price for the soda ash market in Central China is around 1240-1400 yuan/ton for light soda ash, a decrease of 20 yuan/ton compared to last Friday.
According to the commodity analysis system of Shengyi Society, the downstream glass market is running steadily. From April 18th to 25th, glass prices remained at 15.58 yuan/square meter. The capacity utilization rate of the glass market has slightly decreased, downstream demand is poor, market consumption is slow, glass inventory has accumulated narrowly, and market prices are stable and waiting to be seen.
In the future forecast, there will be maintenance plans for some domestic soda ash facilities, resulting in a decrease in capacity utilization and an improvement in market sentiment. However, in terms of demand, downstream entry enthusiasm is not high, and the situation of oversupply in the market still exists. It is expected that the soda ash market will operate steadily in the short term, and specific attention will be paid to downstream demand follow-up.

According to the Commodity Market Analysis System of Shengyi Society, as of April 25th, the average price of acetic acid was 2750 yuan/ton, a decrease of 2.83% compared to the price of 2830 yuan/ton on April 19th, and a decrease of 2.14% compared to the beginning of the month.
This week, the acetic acid market has been weak and declining, with enterprise quotations continuously falling. On the supply side, as the acetic acid plant of a large factory in Shandong is increasing its load, the market capacity utilization rate has increased, the pressure on on-site supply of goods has increased, and enterprises are actively shipping. Downstream market sentiment is not high, and a small amount of purchases are being made on demand, resulting in limited business transactions. Under the supply-demand game, the price of acetic acid continues to decline.
As of April 25th, the market prices of acetic acid in various regions are as follows:
Region /April 18th /April 25th /Rise and fall
South China region /2700 yuan/ton /2675 yuan/ton / -25
North China region /2765 yuan/ton /2675 yuan/ton / -90
Shandong region /2780 yuan/ton /2700 yuan/ton / -80
Jiangsu region /2580 yuan/ton /2540 yuan/ton / -40
Zhejiang region /2825 yuan/ton /2750 yuan/ton / -75
The upstream methanol market fluctuates within a certain range. From April 19th to 25th, the average domestic market price increased from 2413.75 yuan/ton to 2417.50 yuan/ton, with an overall increase of 0.16%. The recent demand for pre holiday stocking of methanol downstream in mainland China has provided some support for the market atmosphere, with smooth shipments from enterprises. However, there is still a wait-and-see attitude towards high prices, and the overall price changes in the market are limited.
The downstream acetic anhydride market continues to decline, with an average ex factory price of 4737.50 yuan/ton on April 25th, a decrease of 1.04% compared to the price of 4787.50 yuan/ton on April 19th. The upstream acetic acid market is weak and declining, with a negative impact on the cost of acetic anhydride. Acetic anhydride companies have a bearish attitude, with prices continuously decreasing. Downstream demand is limited, and market transactions are insufficient. Acetic anhydride prices have been weak during the cycle.
In terms of future market forecast, the acetic acid analyst from Shengyi Society believes that the current utilization rate of acetic acid production capacity is high, the market supply is sufficient, downstream buyers enter the market on demand, the trading atmosphere in the market is weak, and enterprise shipments are limited. Under the supply-demand game, it is expected that the acetic acid market will operate weakly in the short term. Specific attention should be paid to changes in the equipment and downstream follow-up situations.

According to the Commodity Market Analysis System of Shengyi Society, from April 14th to 18th, the domestic aggregated MDI market accelerated its decline, with an average price of 15116 yuan/ton at the beginning of the week and 14300 yuan/ton over the weekend, a decrease of 5.4% during the period and a year-on-year decrease of 15.64%. There is a strong pessimistic atmosphere in the domestic MDI aggregation market during the week, and there is a strong willingness to ship at low prices. The on-site supply is sufficient, but the demand is light, resulting in a wide decline in the aggregated MDI market.

On the supply side, the 1.2 million tons/year MDI plant of Wanhua Ningbo in China began rotating between two sets of plants on March 20th, while other plants were running smoothly. BASF and Huntsman have maintenance plans in May. There is a maintenance plan for the 400000 tons/year MDI plant in Tosa, Japan in May.
On the cost side, raw material pure benzene: After the continuous decline in the pure benzene market, there has been a slight rebound in prices recently, but due to the uncertainty of tariff policies, the future market is not optimistic. Raw material aniline: Aniline continues to fall sharply, with mainstream prices ranging from 7500-7600 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 poor, the enthusiasm for entering the market is not high, and the market is in a stage of oversupply.
Future forecast: The current aggregated MDI market is greatly affected by policies, and the mentality of industry players is relatively pessimistic. At the same time, under the further pressure of weak supply and demand, the price of aggregated MDI has fallen to a low level. It is expected that the market will maintain a weak trend in the short term and the decline will decrease.

The domestic fluorite price trend has slightly declined this week. As of the weekend, the average domestic fluorite price was 3743.75 yuan/ton, a decrease of 0.83% from the beginning of the week price of 3775 yuan/ton and a year-on-year increase of 5.46%.
Supply side: Some manufacturers have started production, and the supply of fluorite has increased
The current situation of the game in the domestic fluorite industry still exists. Overall, the operating rate of enterprises has not changed much. Upstream mining is tight, backward mines will continue to be eliminated, and new mines will be added. Mineral investigation work is still difficult. In addition, national departments need to rectify fluorite mines, and fluorite mining enterprises are facing increasingly strict safety and environmental protection requirements. The difficulty of operating fluorite mines has increased, and the shortage of raw materials has limited the operation of fluorite enterprises. The supply of fluorite sources is still tight. However, as the temperature rises, the previously suspended enterprises gradually start working, and the supply of fluorite enterprises on site has increased. This week, the fluorite market has slightly declined.
Demand side: The price of hydrofluoric acid is temporarily stable, and the refrigerant market is still acceptable
This week, the domestic price of hydrofluoric acid has remained stable, and the mainstream price for hydrofluoric acid negotiations in various regions of China is 11700-12200 yuan/ton. The downstream hydrofluoric acid units are still shut down, and there is little change in the spot supply of hydrofluoric acid. Manufacturers mainly purchase hydrofluoric acid on demand, and the overall production of hydrofluoric acid remains at more than 50%. Fluorine enterprises maintain essential orders, and hydrofluoric acid enterprises are in a loss making state. They are not actively purchasing raw material fluorite, and the fluorite price market has slightly declined due to this news.
The downstream refrigerant market in the terminal is still promising, and the terminal policies of the refrigerant industry are being strengthened. Demand is expected to achieve substantial improvement, and fluorine chemical enterprises within quota control have strong confidence in raising prices in the refrigerant market. Currently, the pace of high price procurement is relatively slow, but the industry’s inventory is transmitting in a positive and orderly manner, and upstream products are mainly purchased on demand. The trend of refrigerant market is temporarily stable, while there is little change in the fluorite market.
In addition to the traditional demand in the refrigerant industry, fluorite, as an important mineral raw material for modern industry, is constantly developing in emerging fields. It is also applied in strategic emerging industries such as new energy and new materials, as well as in national defense, nuclear industry and other fields, including lithium hexafluorophosphate, PVDF、 Graphite negative electrodes, photovoltaic panels, etc., have received certain support in the application of fluorite due to the demand for new energy and semiconductors.
Market forecast: In the near future, the supply of domestic fluorite mines is difficult to improve, and some mines have stopped production and undergone safety inspections. The tight supply of fluorite mines is a major positive support for the fluorite market. However, downstream resistance to high prices is serious, and hydrofluoric acid enterprises mainly purchase on demand without actual demand increase. Overall, the fluorite market price is mainly fluctuating in the short term.

According to the Commodity Market Analysis System of Shengyi Society, the domestic butadiene market experienced a volatile decline in February 2025. From March 1st to 31st, the domestic butadiene market price dropped from 11462.5 yuan/ton to 11000 yuan/ton, with a price drop of 4.03% during the period.

Early month: At the beginning of the month, the butadiene market continued to show a weak trend, and the overall supply in the spot market was loose. The spot market was under pressure, and although the holders had a bullish attitude, the market atmosphere was difficult to support. The demand side synthetic rubber market trend remained weak within the week, and under the pattern of weak supply and demand, the butadiene market continued to delay its weak operation this week.
Mid month: The butadiene market first fell and then rose, but overall it remained weak. At the beginning of the week, the overall trading trend continued from the previous period, and the market was weak. Later, as the downstream synthetic rubber futures market began to improve and mainstream enterprises in East China temporarily shut down, the dual factors led to holders holding up prices and being reluctant to sell, driving the atmosphere of the spot market to improve and market prices to slightly rebound.
Late month: The performance of the domestic butadiene market remains weak, with a slight decrease in spot market prices and a weak market operation. This week, the spot market supply is relatively loose, and the supply side is slightly short. On the demand side, the synthetic rubber market has slightly weakened, and there is a need to replenish raw materials as needed. The mentality of the spot market is weak due to weak supply and demand, and the overall market operation is weak.

As of the 28th, the settlement price of the main contract for WTI crude oil futures in the United States was $69.36 per barrel, and the settlement price of the main contract for Brent crude oil futures was $72.76 per barrel. On the one hand, the United States is increasing its crude oil production, coupled with escalating trade tariffs that may suppress global economic growth, which is bearish for the international oil market. On the other hand, the situation between Russia and Ukraine has eased. If the geopolitical situation between Russia and Ukraine ends, the United States will also ease its oil sanctions against Russia, causing international oil prices to fall. Overall, the trend of international oil prices has declined.
