SunSirs: The Upstream and Downstream Markets Were Stabilizing, the Polyamide Filament Market Was Stable

Price trend

According to the SunSirs’ commodity market analysis system, polyamide filament prices remained stable and weak last week (August 4-10, 2025). As of August 10, 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 remaining unchanged from the previous period.

Analysis review

Last week (August 4-10, 2025), the market trend of polyamide PA6 chips upstream of polyamide yarn gradually stabilized, with limited support on the cost side, high inventory levels on the market, ample supply, and no improvement on the demand side. It was difficult for downstream manufacturers to increase their purchasing enthusiasm, and the market trading atmosphere was general. The price trend of the polyamide fiber market was weak and stable.

Costs: Last week (August 4-10, 2025), caprolactam spot market prices remained weak and stable. Sinopec's weekly caprolactam settlement price was 9,050 RMB/ton (six-month acceptance, interest-free). polyamide PA6 chips market prices remained weak and stagnant, with cost support. As of August 10, 2025, the SunSirs’ caprolactam benchmark price was 9,070 RMB/ton, indicating a weakening and consolidating trend. polyamide PA6 chips and high-speed spinning chips also saw weak, stable prices with minor fluctuations, with cost support being the primary factor.

Supply and demand: During the week, the operating rates of some polyamide filament manufacturers were reduced, and the overall supply in the market declined, 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 their follow-up on just-in-time needs, and most industry players adopted a cautious wait-and-see attitude.

Market outlook

Cost side: As for caprolactam, benzene is expected to be weak, 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 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 anticipates 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 fall. 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 market price of polyamide filament will be mainly weakly consolidated in the short term.
