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 12033 yuan/ton, and the price of activated carbon at the end of the week was 12166/ton, with a price increase of 1.11%.
Most domestic manufacturers of activated carbon have stable quotes this week, with some increasing. The ex factory price of activated carbon for coconut shell water purification in East China is between 8800-13000 yuan/ton, and the market transaction atmosphere is active. We will focus on the market transaction situation.
The shipment of coconut shell charcoal for applications such as gold extraction, water purification, and filter cartridges has accelerated, especially for gold charcoal, with an increase in inquiries from the African market; The shipment of fruit shell charcoal is accelerating. There is a recent rebound trend in imported carbide materials, so pay more attention to the transaction situation.
Prediction: The activated carbon market is experiencing accelerated sales, and it is expected that the price of activated carbon will mainly fluctuate with a strong trend in the short term.

According to the Commodity Market Analysis System of Shengyi Society, as of May 7, 2025, the reference price of n-butanol in Shandong Province, China is 6133 yuan/ton. Compared with April 30 (reference price of n-butanol is 6266 yuan/ton), the price has decreased by 133 yuan/ton, a decrease of 2.13%.
Returning from Labor Day in May, the n-butanol market in Shandong, China, experienced a cold and downward trend. After the holiday, n-butanol factories and suppliers in Shandong region have successively lowered the shipment price of n-butanol by 100-200 yuan/ton. The overall negotiation focus of the n-butanol market has declined. As of May 7th, the reference price of n-butanol in the domestic Shandong region is around 6150-6200 yuan/ton.
Analysis of Market Factors
On the supply side: During the pre holiday period, the supply of n-butanol was loose. During the holiday period, the pressure on the supply side of n-butanol increased. In order to maintain low inventory, n-butanol factories were under pressure to lower market prices, and the overall supply side provided insufficient support for n-butanol.
On the demand side: Before and after the Labor Day holiday, the downstream demand side of n-butanol performed poorly, and downstream users were cautious in stocking up before the holiday, providing limited support to the market. During the holiday period, downstream demand continued to be weak, and the demand side provided loose support to the market.
Market analysis in the future
At present, the trading atmosphere of n-butanol in the market is light, and there is a strong wait-and-see sentiment in the market. Downstream demand is cautious. The n-butanol data analyst from Shengyi Society predicts that in the short term, the n-butanol market in Shandong Province will mainly be weak and stable, and specific changes in supply and demand information need to be closely monitored.

1、 Price trend
According to monitoring data from Business Society, the caustic soda market was weak in April. At the beginning of the month, the average price of caustic soda in Shandong region was 887 yuan/ton. At the end of the month, the price of caustic soda in Shandong region was 807 yuan/yuan, a decrease of 9.02% and an increase of 2.15% compared to the same period last year. On April 29th, the Business Social Chemical Index was 789 points, a decrease of 1 point from yesterday, a decrease of 43.64% from the highest point of 1400 points during the cycle (2021-10-23), and an increase of 31.94% from the lowest point of 598 points on April 8th, 2020. (Note: The cycle refers to the period from December 1, 2011 to present)
2、 Market analysis
According to survey data from Business Society, the overall price of caustic soda is weak. The price of caustic soda in Jiangsu region is currently stable, with a mainstream market price of around 870-980 yuan/ton for 32% ion exchange membrane alkali. The price of caustic soda in Shandong region is running weakly, with a mainstream market price of around 770-850 yuan/ton for 32% ion exchange membrane alkali. In early April, the overall price of caustic soda fell, and the main caustic soda inventory accumulated. With the main regional liquid caustic soda procurement prices once again lowered. The main regional liquid alkali market has experienced a decline, and non aluminum demand is high, so it is necessary to wait and see. The market demand is average. In the middle of the month, the price of caustic soda stopped falling and rebounded, and downstream replenishment was carried out in stages, resulting in an upward trend in caustic soda prices. At the end of the month, caustic soda operated weakly, with sufficient supply from caustic soda enterprises and average downstream demand, resulting in a weak operating trend in caustic soda prices.
Business analysts believe that in the near future, the price of caustic soda has been weak in the operating market, and the downstream demand in China has been average, with no positive support. The comprehensive supply-demand game predicts that caustic soda will maintain a stable operating market in the later stage, depending on downstream market demand.

Aluminum prices began to stabilize after a significant drop in April
After a significant drop in aluminum prices in April, they stabilized. According to the Commodity Market Analysis System of Shengyi Society, as of April 29, 2025, the average price of aluminum ingots in the East China market in China was 20033.33 yuan/ton, a decrease of 2.64% from the market average price of 20576.67 yuan/ton on April 1; Compared to the market average price of 1940 yuan/ton on April 9th, it has increased by 2.52%.
In early April, due to the impact of US tariff news, the commodity market experienced a stress response, and aluminum prices showed a significant decline. Recently, the price of aluminum ingots has rebounded and begun to return to fundamental considerations.
Positive factors:
Aluminum ingots are well stocked. According to inventory data, as of April 28th, the total inventory of electrolytic aluminum in the mainstream domestic market was 643000 tons, a decrease of 129000 tons from the total social inventory of 774000 tons at the beginning of the month (4.3).
The price of alumina has stopped falling, and the cost side profit margin has been fully utilized. The negative feedback on the cost side of electrolytic aluminum has subsided. In March April 2025, alumina enterprises will gradually face losses, and multiple companies will choose the opportunity to carry out maintenance. From the end of March to April, a total of about 11.5 million tons of production capacity underwent maintenance, and some companies provided feedback on their maintenance plans for May. Due to concentrated maintenance and production reduction, the operating capacity of alumina is lower than the theoretical demand for electrolytic aluminum production, the spot supply is tightening, prices have stopped falling, and there has been a slight rebound in the northern region.
Negative factors:
Under the pressure of global trade risks, the uncertainty of aluminum demand has increased. There is an expectation of a transition from shortage to surplus in aluminum supply and demand throughout the year. Under the influence of US tariffs, the export prospects of aluminum containing end products are bleak, and the demand for aluminum ingots is showing a strong internal and weak external trend, putting pressure on aluminum exports.
Future Market:

In the short term, it is expected that the price of aluminum ingots will fluctuate around 20000 yuan/ton and enter a sideways range.

Recently (4.22-4.28), the market price of Shunding rubber has slightly increased. According to the commodity market analysis system of Shengyi Society, as of April 28th, the market price of Shunding rubber in East China was 11950 yuan/ton, an increase of 1.88% from 11730 yuan/ton on the 22nd. The price of raw material butadiene has significantly increased, and the cost support of butadiene rubber has greatly strengthened; Shunding rubber production has slightly increased, leading to a slight increase in supply pressure; Downstream production slightly decreased, and overall inquiries in the Shunding rubber market remained flat. Merchant offers slightly increased, with mainstream quotes in Qilu, Daqing, Sichuan, and Yangtze Shunding in East China ranging from 11900 to 12200 yuan/ton as of April 28th; The price of some private Shunding is around 11700~11900 yuan/ton.
Recently (4.22-4.28), the price of butadiene has significantly increased, and the cost support of butadiene rubber has strengthened. According to the Commodity Market Analysis System of Shengyi Society, as of April 28th, the price of butadiene was 9300 yuan/ton, an increase of 13.41% from 8200 yuan/ton on the 22nd.
Recently (4.22-4.28), the construction of domestic butadiene rubber plants has rebounded, with an overall construction rate of around 6.70%. There are still some plans to restart the maintenance equipment in the later stage, and the supply of butadiene rubber is expected to increase.
On the demand side, downstream tire production has slightly decreased, and there is a strong wait-and-see atmosphere in the Shunding rubber market, with flat inquiries. As of April 25th, the operating load of semi steel tires in domestic tire enterprises was around 7.8%; The production of all steel tires by tire companies in Shandong Province has slightly decreased to around 6.3% of the load.
Market forecast: From a fundamental perspective, analysts from Shengyi Society believe that the current price of butadiene has significantly increased, and the cost support for butadiene rubber has greatly strengthened; However, due to the impact of the international trade situation, downstream inquiries are cautious and market transactions are flat in the short term. In addition, with the increase in production of butadiene rubber, it is expected that the butadiene rubber market will continue to consolidate weakly in the later stage.

This week (April 21-27, 2025), the upstream raw material market prices continued to decline, while downstream manufacturers held onto their demand and followed suit. There was no positive support from both the cost and demand sides, and some nylon filament manufacturers had high inventory. With mixed news on the market, the price trend of nylon filament continued to decline.
According to the Commodity Market Analysis System of Shengyi Society, the price of nylon filament continued to decline weakly this week (April 21-27, 2025). As of April 27, 2025, DTY (premium product) of nylon filament in Jiangsu region; 70D/24F) quoted 15340 yuan/ton, a decrease of 140 yuan/ton from last week’s price, a weekly decrease of 0.90%; Nylon POY (premium product; 86D/24F) quoted 12675 yuan/ton, a decrease of 225 yuan/ton from last week’s price, a weekly decrease of 1.74%; The price of nylon FDY (premium: 40D/12F) is reported at 15875 yuan/ton, a decrease of 200 yuan/ton or 1.24% from last week’s price.
The raw material market continues to decline
In terms of cost, the weekly closing price of Sinopec’s high-end caprolactam has been lowered to 9430 yuan/ton. The market price of high-speed spinning nylon PA6 slices has continued to decline during the week, and the price center of the raw material market has declined. It is difficult to find favorable support for the cost side. As of April 27, 2025, the benchmark price of caprolactam in Shengyi Society was 9360 yuan/ton, with a weekly decline of 3.11%. During the week, the market price of high-speed spun nylon PA6 chips fell sharply, with a 2.92% drop in nylon PA6 prices, indicating weak cost support.
Supply and demand: This week (April 21-27, 2025), some nylon filament manufacturers lowered their equipment operating rates to control inventory, resulting in a decline in overall industry supply and mediocre performance on the supply side; The issuance of new orders in the terminal market is limited, and there is a certain degree of risk aversion in the downstream market. The purchasing enthusiasm is not high, and the demand side is dragging down the market trend. The market price of nylon filament is under pressure and declining, and the overall profit margin of the market is not ideal.
Future forecast
Cost aspect: There is a lack of significant boost in raw material supply, and there is ample supply of caprolactam in the market. Downstream enthusiasm for receiving goods is not high, and it is expected that the market price of caprolactam will narrow down next week. In terms of nylon PA6 slicing, the negative pressure on the cost side has decreased, and the operating level of the nylon PA6 slicing market is at a low level. Downstream manufacturers may gradually replenish their inventory due to low demand. It is expected that the nylon PA6 slicing market will slightly decline next week. Therefore, it is expected that there may be a possibility of a decline in the raw material market prices next week.
On the supply and demand side, shipments are not ideal, inventory continues to accumulate, and some nylon filament manufacturers still have plans to lower their operating loads. It is expected that the supply of nylon filament in the market may still decrease in the short term; The demand in the terminal market remains weak, and downstream manufacturers are holding onto rigid procurement. There is no sign of improvement on the demand side, so it is expected that the demand side of the nylon filament market will perform poorly next week.
Overall, the spot market for raw material caprolactam and the PA6 chip market may continue to decline, with a lack of cost support. Some downstream manufacturers have plans to reduce production, making it difficult for demand to improve. Business analysts predict that the nylon filament market prices will continue to decline next week, with an expected drop of 100-200 yuan/ton.

As of April 25th, the reference price for cyclohexanone market in Shandong is around 7600-7750 yuan/ton, with a price reduction of around 400-600 yuan/ton for the month.
Market influencing factors
In terms of supply and demand: During the month, the overall trading atmosphere in the cyclohexanone market in Shandong was poor, with abundant supply on the supply side and slow overall market shipments. The supply side remained under pressure. In terms of downstream demand, the overall market support for cyclohexanone downstream demand is insufficient, and the downstream chemical fiber market is cautious in following up on new orders. The demand transmission is slow, and the contradiction between cyclohexanone supply and demand is intensifying.
