SunSirs: Polyamide Filament Prices Remained Stable at Low Levels due to Weak Demand

Price trend

According to the SunSirs commodity market analysis system, polyamide filament prices remained stable at low levels last week (August 18-24, 2025). As of August 17, 2025, polyamide filament DTY (premium grade; 70D/24F) in Jiangsu Province was quoted at 14,320 RMB/ton; polyamide POY (premium grade; 86D/24F) was quoted at 12,050 RMB/ton; and polyamide FDY (premium grade: 40D/12F) was quoted at 14,900 RMB/ton, all unchanged from the previous period.

Analysis review

Last week (August 18-24, 2025), the upstream raw material market trend of polyamide filament was weak and fell slightly. The polyamide PA6 chip market was mainly consolidating. The cost side was insufficiently supported, the inventory level on the market was high, the industry supply was sufficient, and the downstream market demand showed no signs of improvement. The operating rate of downstream enterprises was not high, and most of them maintained just-in-time purchases. The trading atmosphere on the market was not good, and most industry players adopted a cautious wait-and-see attitude. The polyamide filament market was stable and prices remained low.

Costs: Last week (August 18-24, 2025), caprolactam spot market prices remained weak and stable. Sinopec's weekly caprolactam settlement price was 9,575 RMB/ton (six-month acceptance, interest-free). The polyamide PA6 chips market was primarily consolidating, with a weekly decline of 0.64%, supported by weak costs. As of August 24, 2025, the SunSirs’ caprolactam benchmark price was 8,986 RMB/ton, showing a weak consolidation trend, with a weekly decline of 0.37%. The polyamide PA6 chips and high-speed spinning chips market was also weak and stable with minor fluctuations, supported by weak costs.

Supply and demand: The operating rates of some polyamide filament manufacturers decreased during the week, and the overall supply in the market was sufficient, but the industry's inventory level continued to increase, and the supply side performed poorly; the terminal market demand was weak, and some downstream manufacturers reduced production or switched production, which reduced the demand for polyamide filament. It was difficult to find favorable support on the demand side, and most people maintained a cautious wait-and-see attitude.

Future outlook:

Cost side: As for caprolactam, benzene is expected to be weaker, and chip manufacturers are not very enthusiastic about purchasing caprolactam. It is expected that the caprolactam market will be mainly weak and low next week; as for PA6 chips, the cost side has limited support, the supply level of PA6 chips market may continue to increase, and the downstream market demand is weak. It is expected that the market price of polyamide PA6 chips will fall weakly.

Supply and Demand: August is traditionally a low season for demand, and with no signs of improvement in end-market demand, downstream purchasing enthusiasm is subdued. Therefore, SunSirs anticipate a decrease in polyamide filament market demand next month. If demand does not improve significantly, some polyamide filament manufacturers may reduce their production capacity due to high inventory levels. Meanwhile, the industry continues to release new production capacity, leading to a decrease in polyamide filament market supply next month.

On the whole, both the spot market of upstream raw material caprolactam and the market of polyamide PA6 chips are likely to continue to decline. The cost side lacks support, and the demand in the downstream market is unlikely to improve. The demand side is dragging down the market trend. Under these two negative factors, analysts of SunSirs predict that the polyamide filament market will be stable in the short term, with prices mainly consolidating weakly.
