Jiangsu region /2500 yuan/ton /2400 yuan/ton /2490 yuan/ton
Zhejiang region /2700 yuan/ton /2600 yuan/ton /2700 yuan/ton
In the first half of May, the price of acetic acid fell weakly, mainly due to the high utilization rate of on-site production capacity and sufficient supply of market goods. However, downstream stocking was not active, resulting in significant pressure on enterprise shipments and a continuous shift in the focus of acetic acid transactions; In the second half of the month, prices first rose and then fell. News of equipment maintenance in the early stage was released one after another, and the mentality of the industry was optimistic. Acetic acid prices rose, while enterprise shipments increased, inventory pressure weakened, and the market trend continued to rise. Due to the obvious intention of enterprises to rise, downstream sentiment towards high prices gradually increased, and the enthusiasm for entering the market weakened. At the end of the month, some areas did not sell their products, and prices fell.
The methanol market on the raw material side is weak and declining. As of May 31st, the average price in the domestic market was 2250 yuan/ton, a decrease of 7.79% compared to the beginning of the month price of 2440 yuan/ton.

Although downstream external procurement and equipment start-up have provided some support to the market, overall demand is weak, and the domestic methanol market is under pressure and declining.
Market forecast: Business Society analysts believe that the current acetic acid market is mainly stable, with poor shipments from enterprises, weak mentality of industry players, low enthusiasm for downstream market entry, limited market trading, and an increase in capacity utilization in the future. On site supply will continue to exceed demand, and it is expected that the acetic acid market will operate weakly in June. Specific attention should be paid to downstream follow-up situations.

According to the Commodity Market Analysis System of Shengyi Society, the domestic ethanol market saw a unilateral upward trend in May. From May 1st to 30th, the average price of domestic ethanol producers increased from 5233 yuan/ton to 5438 yuan/ton, with a price fluctuation of 3.93% and a year-on-year decrease of 8.86%.
In the first half of the month, some enterprises in certain regions continued to conduct inspections on their equipment, resulting in limited ethanol supply and strong prices of raw material corn, leading to significant cost pressures. As a result, enterprises showed a clear willingness to raise prices.

In mid month, the ethanol market continued to rise, with some regions facing significant cost pressures for enterprises. Orders were shipped, production was not high, inventory pressure was not significant, and there was a clear intention to increase prices. However, new orders were limited in transactions.
At the end of the month, the domestic ethanol market prices stabilized at a high level. Enterprises in the Northeast region continue to undergo rotation inspections, with low production rates and a clear willingness to raise prices. In the short term, without inventory pressure, prices may remain stable. The transaction situation in Henan region is still acceptable, with prices maintaining a high level of consolidation.
On the cost side, in the first half of the month, corn prices remained relatively firm, and the purchase prices for deep processing have also increased. Prices in production areas have continued to rise recently, and traders’ shipping mentality has slightly changed. Overall, there is not much corn surplus in the production area, and the quotation is firm. The price of corn fluctuated in the second half of the month. The arrival volume of deep processed corn in Shandong and Hebei is still acceptable, and some enterprises have seen a narrow reduction in corn prices. Henan’s deep processing enterprises have generally received goods and prices have increased. Before the wheat harvest, grassroots grain points were able to monetize their shipments, but overall supply pressure was not significant. The cost of ethanol is influenced by favorable factors.
There are unlikely to be significant favorable factors in the supply of ethanol.
On the demand side, from the demand side, the demand for Baijiu fluctuates little, and the downstream stock of chemical industry needs to be replenished. The short-term demand for ethanol has a moderate impact.
Future forecast: Limited supply, partial orders shipped, downstream stocking nearing completion. The ethanol analyst from Shengyi Society predicts that the domestic ethanol market will remain strong and stable in the short term.

In May 2025, the upstream cost support of nylon filament was insufficient, and the purchasing power of downstream enterprises was poor, resulting in an overall increase in inventory levels in the industry.

As of May 30, 2025, DTY (premium product) of nylon filament in Jiangsu region; 70D/24F) quoted 14760 yuan/ton, a decrease of 280 yuan/ton from the previous month, a monthly decrease of 1.86%; Nylon POY (premium product; The quotation for 86D/24F is 12300 yuan/ton, a decrease of 200 yuan/ton from the previous month, with a monthly decrease of 1.60%; The price of nylon FDY (premium: 40D/12F) is reported at 15400 yuan/ton, a decrease of 250 yuan/ton or 1.60% compared to the previous month.
Since the beginning of the month, the weekly closing price of Sinopec’s caprolactam has been continuously lowered, and the market for high-speed spinning of nylon PA6 chips has been under pressure and downward, with weak cost support; The demand in the terminal market is showing signs of fatigue, downstream yarn factories are experiencing poor shipments, and their enthusiasm for raw material procurement has declined, resulting in a significant increase in inventory in the nylon filament market. Under multiple negative factors, the price of nylon filament market continues to decline.
Until the end of the month, the market price of nylon filament rebounded slightly. The strong upward trend in crude oil and pure benzene market prices has driven the continuous rise in the spot market of caprolactam and the market for nylon PA6 chips. Subsequently, the weekly closing price of caprolactam by Sinopec has been raised, and cost support has been strengthened; Individual downstream factories stocked up on dips, resulting in a slight increase in demand. Amidst mixed market news, the nylon filament market price saw a narrow rise before consolidating and operating.
As of the end of the month, there has been no significant improvement in terminal demand, and the demand side has constrained the raw material market from bottom to top. The price of nylon filament market has entered a downward channel.
The raw material market continues to weaken and decline
In terms of cost, the weekly settlement price of Sinopec Caprolactam first fell and then rose, with a significant decrease in monthly settlement price. The market for high-speed spinning of nylon PA6 slices slightly fell, and the price center of the raw material market shifted downwards, with weak support on the cost side. As of May 30, 2025, the benchmark price of caprolactam in Shengyi Society was 9190 yuan/ton, with a monthly decline of 0.77%. Nylon PA6 experienced a monthly decline of 3.04%.
Supply and demand: In May, there was little fluctuation in the overall supply of nylon filament market. Starting from the May Day holiday, some nylon filament manufacturers have reduced their load operation or stopped for vacation, resulting in a decrease in on-site supply. By mid month, the early parking inspection devices in Zhejiang have gradually resumed, and with the continuous release of new production capacity in the industry, the supply has gradually increased. The demand in the terminal market has not improved, foreign trade orders are insufficient, domestic demand is limited, downstream manufacturers’ finished product inventory continues to accumulate, and the demand for nylon filament market is gradually decreasing, making it difficult to find favorable support on the demand side.

Future forecast
Cost aspect: In terms of caprolactam, pure benzene is expected to be weak, and the supply of caprolactam may recover next month. Slice manufacturers have low enthusiasm for purchasing caprolactam, and it is expected that the caprolactam market will continue to decline next month; In terms of PA6 slicing, cost support is limited, and the supply level of PA6 slicing market may continue to improve. Downstream market demand is weak, and it is expected that the PA6 slicing market price will decline next month. Therefore, it is expected that the market price trend of nylon filament raw materials will be poor next month, and the cost support will be insufficient.
Supply and demand: June is a transitional period from the market to the traditional off-season, coupled with the lack of signs of improvement in terminal market demand and low purchasing enthusiasm in downstream markets. Therefore, it is expected that the demand for nylon filament market may decrease next month. If there is no significant improvement in demand, under the pressure of large inventory, some nylon filament manufacturers may have the possibility of reducing production capacity, while the industry continues to release new production capacity. Therefore, it is expected that the supply of nylon filament market will decrease next month.
Overall, both the upstream raw material caprolactam spot market and the nylon PA6 chip market are likely to decline, with a lack of cost support and difficulty in improving downstream market demand. The demand side is dragging down the market trend, and under the dual negative factors, analysts from Shengyi Society predict that the nylon filament market price will continue to be weak next month, with a decline of 100-300 yuan/ton.
