Price trend

Last week (September 8-14, 2025), demand remained weak, and the polyamide filament market remained weak and stable. Sinopec's high-end caprolactam settled at 9,184 RMB/ton. The polyamide PA6 chips market was stable, with moderate cost support and no significant improvement in end-user demand. Downstream manufacturers mostly followed up on demand, resulting in a subdued trading atmosphere. polyamide fiber prices were mainly consolidating, remaining weak and stable.

According to the SunSirs commodity market analysis system, polyamide filament prices remained stable at low levels last week (September 8-14, 2025). As of September 14, 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

Costs: Last week (September 7-14, 2025), caprolactam spot market prices weakened and fell. Sinopec's weekly caprolactam settlement price was 9,184 RMB/ton (six-month acceptance, interest-free). The polyamide PA6 chips market was primarily consolidating, with stable prices and weak cost support. As of September 14, 2025, the SunSirs caprolactam benchmark price was 8,806 RMB/ton, reflecting a weak consolidation trend and a weekly decline of 1.27%. The polyamide PA6 chips high-speed spinning chips market was also weak, with prices remaining stable with minor fluctuations, primarily supported by weak cost support.

Supply and demand: The operating rates of some polyamide filament manufacturers decreased during the week, and the overall market supply 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.

Market 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 weakly consolidated at low levels in the short term; as for polyamide 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: September is a month of traditional market demand and a positive trading atmosphere, leading to an expected increase in polyamide filament market demand next month. However, due to inventory pressures, some polyamide filament manufacturers may reduce their production capacity. Furthermore, with the continued release of new production capacity, overall supply pressure remains high.

On the whole, the spot market of upstream raw material caprolactam and polyamide PA6 chips will continue to operate in a weak position, with a lack of support on the cost side and relatively high supply pressure. It is difficult for the downstream market demand to improve significantly, and it will mainly follow up on demand. There is no good news. Analysts of SunSirs predict that the polyamide filament market will continue to be weak and stable in the short term, with prices mainly consolidating weakly.
