In the third quarter of 2025, the nylon filament market lacks favorable conditions, and the overall price trend is downward. Taking nylon DTY as an example, as of September 30th, the Jiangsu region’s nylon filament DTY (premium product; 70D/24F) quoted 13880 yuan/ton, a decrease of 4340 yuan/ton from the same period last year, a decrease of 23.82%.
The price of nylon filament has dropped significantly
Specifically, on the one hand, the weak downward trend in the price of raw material nylon PA6 for high-speed spinning has had a negative impact on the cost of nylon filament; On the other hand, the contradiction between supply and demand is prominent, with downstream orders being relatively low during the quarter. In the context of high inventory, the main focus is on digesting inventory, and the enthusiasm for purchasing upstream raw materials is insufficient. The demand transmission from bottom to top is not smooth, resulting in continuous weak shipments from nylon filament manufacturers and increasing inventory pressure. In addition, from the perspective of downstream weaving industry, there is insufficient action on the price of raw fabric, resulting in low profits and thus suppressing the price of nylon filament. Overall, in the absence of favorable market conditions, the price of nylon filament yarn showed a downward trend throughout the quarter.
Raw material side runs empty
In the third quarter of 2025, the domestic nylon PA6 market will experience a weak downward trend, mainly influenced by two factors: firstly, the supply of nylon PA6 will increase, but the consumption will decrease, and the supply-demand contradiction will intensify; Secondly, the price of raw material PA6 for high-speed spinning has decreased. As of September 30th, the price was 10133 yuan/ton, a decrease of 4.41% from early July, indicating a bearish cost outlook. As a result, the price of nylon filament has decreased.
Prominent supply-demand contradiction
In the third quarter of 2025, only the transaction situation of nylon DTY fine denier was relatively good, and some enterprises had a backlog phenomenon. However, the overall activity was far below the same period last year. Overall, the market demand performance was weak, leading to increasing inventory pressure on nylon factories. Specifically, downstream orders are relatively low and inventory is high, so there is a lack of speculative demand for nylon filament. As of September 30th, the operating rate of downstream weaving machines was 69%, a decrease of 5 percentage points from the same period last year. As a result, the inventory level of nylon manufacturers continues to increase, and although some manufacturers have reduced production operations, the relief effect on inventory pressure is limited.
The raw material market in the fourth quarter may be weak and difficult to change
It is expected that the market price of nylon PA6 will remain low in the fourth quarter, which lacks support for the price of nylon filament. Specifically, in terms of supply and demand, new PA6 production capacity will continue to be released, with plans to add 600000 tons of production capacity within the quarter. By the end of the year, the total industry production capacity may reach 8.858 million tons, with a significant increase in supply. Especially this year, the market has shown the characteristics of weak peak season and even weaker off-season. By comparison, it is expected that the production of PA6 in the fourth quarter will be 1.787 million tons, with a consumption of 1.466 million tons, and the supply-demand gap will expand to over 300000 tons. In terms of cost, the weak downstream demand for pure benzene in the fourth quarter and the high amount of pure benzene arriving in Hong Kong may have a negative impact on prices, which will then be transmitted downwards to the caprolactam market and PA6 market, thus lacking support for nylon filament.
The supply-demand contradiction may continue

On the supply side, according to incomplete statistics, there may be about 440000 tons of new production capacity released in the fourth quarter of nylon yarn. However, under high inventory pressure, it is expected that the industry’s operating level may be significantly lower than in the third quarter. As a result, production may be around 1.1258 million tons, a decrease of 1.62% month on month, which is relatively small, and the supply side may continue to be under pressure.
In terms of demand, terminal demand may remain weak and be transmitted upwards to the weaving process, making it difficult to effectively alleviate the pressure on raw fabric inventory. Therefore, it is expected that demand will continue to be light. In addition, the rise in raw fabric inventory prices is difficult to start, which may continue to suppress the price of nylon filament.
Overall, according to previous years, October is the traditional peak demand season for “golden September and silver October”, and the probability of nylon filament prices rising is relatively high. From November to December, the probability of a downward trend is relatively high. However, in the fourth quarter, nylon filament prices may show a downward trend due to cost declines and prominent supply-demand contradictions. Therefore, it is expected that October will break the seasonal pattern, and the seasonal pattern from November to December will remain unchanged. Business analysts predict that the mainstream transaction prices of domestic nylon filament will continue to decline in the fourth quarter due to supply side pressure and weak raw material and demand sides.

According to the Commodity Market Analysis System of Shengyi Society, lithium carbonate has recently ended its volatile market and rebounded. On October 21st, the benchmark price of battery grade lithium carbonate in Shengyi Society was 75016 yuan/ton, an increase of 2.74% compared to the same period last week (October 14th), a month on month increase of 2.93%, and a year-on-year decrease of 7.84%. The benchmark price of industrial grade lithium carbonate trading company is 73166 yuan/ton, an increase of 2.81% compared to the same period last week (October 14th), a month on month increase of 2.69%, and a year-on-year decrease of 7.15%.
Boosting sentiment in futures market
Last week (October 13-1017), the warehouse receipts for lithium carbonate futures decreased from 42669 lots to 30686 lots, resulting in a destocking of 12000 tons of lithium carbonate, reflecting strong demand in the current market and insufficient downstream stocking.
Explosive demand: dual wheel drive of new energy and energy storage
New energy vehicle demand exceeds expectations: According to data from the China Association of Automobile Manufacturers, wholesale sales of new energy passenger vehicles reached 1.5 million units in September, a year-on-year increase of 22%, and single month sales reached a historic high. The strong demand from end-users is directly transmitted to the upstream industry chain. The delivery cycle of orders from leading battery companies such as CATL and BYD has been extended to 45 days, and the production rate in September remains above 95%. The production of positive electrode material factories continues to rise month on month, forcing the concentrated release of demand for lithium carbonate procurement.
The demand for energy storage has exploded: According to the production scheduling data of domestic battery companies in October, the total output of power, energy storage, and consumer batteries reached 186GWh, an increase of 22.4% compared to the previous month. Among them, the proportion of energy storage battery cell production was as high as 40.3%, and the production lines of top enterprises were operating at full capacity. At the domestic policy level, the “Special Action Plan for the Large scale Construction of New Energy Storage (2025-2027)” specifies that the installed capacity will exceed 100 million kilowatts in the next three years, further opening up the consumption space of lithium resources.
Continuously reducing inventory to solidify the price foundation
As of early October, the total inventory of lithium carbonate in China decreased by 2023 tons to 134802 tons month on month, providing solid support for spot prices due to the continuous destocking trend.
The data analyst of Shengyi Society believes that lithium carbonate is currently in a short-term strong oscillation under tight balance, but the total inventory of 130000 tons still suppresses the increase, making it difficult to quickly break through the previous high point. It is expected that the price will continue to fluctuate, and specific market changes still need to be monitored.

Last week (October 13-19, 2025), the execution of orders was the main focus, and the trend of the adhesive short fiber market remained stable. The fluctuation of the raw material main material dissolution slurry market was not significant, and the performance on the cost side was average, with limited support on the cost side; The overall inventory level in the market is not high, and there is no obvious inventory pressure at the moment. Supply side support still exists, and downstream cotton yarn factories mainly consume inventory, following up on demand. The overall trading atmosphere in the market is stable, and the prices of viscose staple fiber market are weak and consolidating, continuing the stable trend.
According to the Commodity Market Analysis System of Shengyi Society, last week (October 13-19, 2025), the market price of viscose staple fiber was weakly stable. As of October 19, the average market price of viscose staple fiber was 13120 yuan/ton, which was the same as the previous price.
In terms of cost: Last week (October 13-19, 2025), there was little change in the market price of raw material dissolving pulp, with a weak and stagnant situation. The cost side performance was average and limited support. As of now, the price of domestic dissolving pulp is around 6700 yuan/ton, the price of external broad-leaved pulp is around 800 US dollars/ton, and the price of coniferous pulp is around 870 US dollars/ton. The market prices of auxiliary materials such as liquid alkali and sulfuric acid remain stable but fluctuate slightly, with average cost support.
Low inventory level
The industry supply remains stable, and the current daily operating rate in the market remains at around 75%. The inventory levels of various adhesive short fiber manufacturers are not high, and downstream yarn enterprises pick up goods according to demand. The overall inventory of the adhesive short fiber market has decreased, and the supply fluctuation in the industry is not significant. Some manufacturers have low inventory, and the support from the supply side is limited.
Downstream on-demand pickup
The operating rate of downstream cotton yarn market equipment has slightly increased, and price fluctuations are not significant. As of October 19th, the price of ring spun R30S in Jiangsu region is around 17200 yuan/ton, and the price of ring spun R40S is around 18300 yuan/ton. The market is in a traditional off-season of demand, and downstream cotton yarn market transactions are not ideal. Only a few models of vortex spun cotton yarn have slightly better export orders. Cotton mills mainly consume raw material inventory and replenish urgently needed goods, with no significant improvement in demand.
Market forecast
On the raw material side, the main material dissolution slurry market and the auxiliary material sulfuric acid market are generally stable, while the liquid alkali market may experience a narrow decline. Therefore, it is expected that the market price trend of adhesive short fiber raw materials will decline in the short term, and the cost support will be insufficient.
Supply and demand side: The operating rate of the adhesive short fiber market equipment may not fluctuate significantly, and some manufacturers have low inventory levels. Therefore, it is expected that the supply side support of the adhesive short fiber market will be strong in the short term; The demand in the terminal market has increased, with on-demand procurement being the main focus. It is expected that the driving force of the adhesive short fiber market from the demand side will be limited in the short term.
Overall, the main raw material dissolution slurry market may be weak and stagnant, with sufficient overall supply. Downstream yarn factories mainly sign orders and purchase on demand. Under the interweaving of on-site news, adhesive short fiber manufacturers may maintain their previous quotations. Therefore, Business Society analysts predict that the domestic adhesive short fiber market will remain stable with small movements in the short term, and the price is expected to be around 13000-13200 yuan/ton for acceptance.

According to the analysis of the Business Society’s market monitoring system, on October 17th, the reference price for the domestic market of silicon metal # 441 was 9680 yuan/ton, and on October 12th (the market price of silicon metal # 441 was 9700 yuan/ton), the price decreased by 20 yuan/ton, a decrease of 0.21%.
This week, some brands in the domestic silicon metal market have been declining
From the commodity market analysis system of Shengyi Society, it can be seen that this week, the domestic silicon metal market as a whole showed a narrow downward trend, and the market prices of some grades of silicon metal in some regions were narrowly lowered, with an overall decrease of around 50-100 yuan/ton. As of October 17th, the market price of metal silicon # 441 in Huangpu Port area is reference to 9600-9800 yuan/ton, with a decrease of 50 yuan/ton during the week. The market price of metal silicon # 441 in Tianjin Port area is reference to 9400-9700 yuan/ton, with a decrease of 50 yuan/ton during the week. The market price of metal silicon # 553 in East China area is reference to around 9300-9400 yuan/ton, with a decrease of 50 yuan/ton during the week. The market price of oxygen 553 # in Xinjiang area is reference to around 8600-8900 yuan/ton, with a decrease of 100 yuan/ton during the week.
Analysis of Market Factors
On the supply side: Currently, the supply and demand game in the silicon metal market is more evident, and the supply and demand game stimulates narrow fluctuations in market prices. In terms of supply, currently, the operating rate of the silicon industry in Xinjiang continues to increase, and the overall operating rate in Xinjiang is expected to climb to a high point this year. The operating rates in the northwest and Yunnan regions remain stable, while silicon companies in Sichuan have started to reduce production slightly. The operating rate in Sichuan has decreased narrowly, and the overall market supply has continued to increase.
On the demand side: Currently, the demand for metallic silicon is showing some weakness, with an increase in downstream organic silicon plant maintenance and a decline in overall production. The demand for industrial silicon raw materials will be loosened, and although the overall production of polycrystalline silicon will continue to rise narrowly, the purchasing mentality for raw materials is cautious. The downstream aluminum alloy industry has stable production and demand. But with a slight increase in overall inventory in the market, the overall support provided by demand is limited.
Market analysis in the future
At present, the supply and demand transmission of metal silicon is relatively slow, and the regional differentiation characteristics of the metal silicon market are more obvious. The southwest region is gradually reducing production, while the northwest region continues to increase production. The overall supply pressure and demand drag game in the market continue. The metal silicon data analyst of Business Society predicts that in the short term, the domestic metal silicon market will mainly adjust and operate within a narrow range, and specific changes in supply and demand news need to be paid more attention to.

price trend
According to the bulk ranking data from Shengyi Society, the domestic PC market in China experienced a stagflation and correction in October. The spot prices of some brands have fallen. As of October 16th, the mixed benchmark price of Business Society PC is around 14483.33 yuan/ton, with a price increase or decrease of+0.12% compared to early October.
Root cause analysis
On the supply side: In the first half of October, domestic PC aggregation enterprises had a large and stable load with small fluctuations. As of the time of writing, the industry’s operating rate is about 81%, with an average weekly output of around 68000 tons, with limited changes compared to the beginning of the month. However, many companies in the future will have centralized release of maintenance arrangements. In terms of inventory, there is a high-level stalemate, and the pattern of abundant PC supply remains unchanged. The positive news of early maintenance has basically been exhausted, and the market is waiting for the implementation of maintenance arrangements for many aggregation plants. Overall, the weak reality and strong expectations on the PC supply side provide moderate support for PC.
In terms of raw materials, it can be seen from the above chart that the bisphenol A market significantly declined in the first half of October. Upstream phenol and acetone both suffered heavy setbacks, which has a significant impact on the bisphenol A market. In addition, the continuous weakness of bisphenol A consumption has led to a rapid decline in spot prices due to multiple factors. The current market atmosphere remains bleak, with many businesses offering discounts and taking orders, making it difficult for the market to have a chance to stop falling. It is expected that bisphenol A will continue to seek a balance point downwards in the future, while its support effect on the cost of PC will weaken.
On the demand side: October is still in the traditional peak season for PC, but the downstream factory load of the “Golden Ten” this year is not ideal, and the inventory remains at a weak level of rigid demand. Pre holiday warehouse building is not obvious, and post holiday inventory digestion is slow. Although there were maintenance signals that stimulated the early rise of spot prices, as the positive news gradually dissipated, market trading activity declined. Merchants tend to focus on selling goods to recoup funds, leading to a concentration of profit taking and price stagnation and decline. In addition, the industry’s market momentum has been weak for a long time, social inventory is high, and on-site sources of goods are abundant. Although there are collective price increases from aggregation factories, terminal enterprises are resistant to high priced sources of goods. After the demand for filling vacancies in the first half of the month was met, the speed of market supply circulation slowed down again. Overall, the demand side provides average support for PC spot prices.
Future forecast
In October, the domestic PC market in China experienced stagflation and fell back. The upstream bisphenol A market is still in a downward trend, and the cost value of PC support has collapsed. Domestic PC aggregation plants have large and stable loads with small fluctuations, and maintenance in the future is relatively concentrated. The spot price of PC has risen to a high level in the early stage, and the current market trading situation is not good. It is expected that the PC market will be hindered from rising in the short term and enter a consolidation market.
