SunSirs: Oversupply, Polyamide Filament Market Continued to Decline

Last week (October 13-19, 2025), the market trend of polyamide PA6 chips upstream of polyamide filament was weak, favorable support on the cost side was hard to find, the supply in the market was loose, the contradiction between supply and demand was prominent, there was overcapacity, and orders from all downstream links were relatively small. In the case of high inventory, the main focus was on digesting inventory. From the perspective of the downstream weaving industry, the upward momentum of grey cloth prices was insufficient and profits were low, which suppressed the price of polyamide filament and the polyamide filament market continued to decline.

Polyamide filament market continued to decline 

According to the SunSirs commodity market analysis system, polyamide filament prices declined weakly last week (October 13-19, 2025). As of October 19, 2025, polyamide filament DTY (premium grade; 70D/24F) in Jiangsu Province was quoted at 13,660 RMB/ton, down 220 RMB/ton from the same period last week, a weekly decline of 1.59%. polyamide POY (premium grade; 86D/24F) was quoted at 11,400 RMB/ton, down 175 RMB/ton from the same period last week, a weekly decline of 1.51%. polyamide FDY (premium grade: 40D/12F) was quoted at 14,325 RMB/ton, down 175 RMB/ton from the same period last week, a weekly decline of 1.21%.

The raw material end was running empty

Costs: Last week (October 13-19, 2025), caprolactam spot prices continued to decline, with Sinopec's weekly caprolactam settlement price at 8,058 RMB/ton (six-month acceptance, interest-free). The polyamide PA6 chips market was primarily consolidating, with stable prices and weak cost support. As of October 19, 2025, the SunSirs caprolactam benchmark price was 8,460 RMB/ton, reflecting a weak consolidation trend and a weekly decline of 2.31%. The market price of polyamide PA6 chips for high-speed spinning remained stable with minor fluctuations during the week, primarily driven by weak cost support.

Supply and Demand: polyamide filament manufacturers maintained sufficient supply throughout the week, but industry inventory levels continued to increase. Some companies experienced queues of orders, but overall activity was far below the same period last year. Overall, weak market demand led to increasing inventory pressure at polyamide manufacturers. Supply-side performance was poor; end-market demand was weak, and some downstream manufacturers reduced or switched production, reducing demand for polyamide filament. Favorable support on the demand side was difficult to find, and most industry players maintained a cautious wait-and-see approach, focusing on just-in-time demand.

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: While October is traditionally peak season, the distinction between peak and off-season has become less pronounced in recent years, and trading sentiment remains predominantly weak. Therefore, sluggish demand for polyamide filament is expected to persist next month. However, under current inventory pressures as of October 19, some polyamide filament manufacturers may reduce their production capacity. Furthermore, with the industry continuing to release new production capacity, overall supply pressure remains relatively 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. The contradiction between supply and demand is prominent, and there is no good news. Analysts of SunSirs Exchange predict that the polyamide filament market will continue to be stable at a low level in the short term, with prices mainly consolidating weakly.
