Analysis review

Last week (July 14-20, 2025), the market trend for high-speed spinning of raw material polyamide PA6 slices declined, with weakened cost support and high inventory levels in the market. The supply side performed well, while the demand side remained weak. Some polyamide filament manufacturers had poor shipments, and low-priced sources increased in the market. Amidst mixed news in the market, the price of polyamide filament continued to decline.

In terms of cost: Last week (July 14-20, 2025), the spot market price of caprolactam was weak during the week, with Sinopec's high-end caprolactam closing price of 9,095 RMB/ton. The polyamide PA6 chip market experienced a slight decline, indicating insufficient support on the cost side. As of July 20, 2025, the benchmark price of caprolactam in SunSirs was 8,943 RMB/ton, with a weak price and a weekly decline of 0.43%. During the week, the market price of high-speed spun polyamide PA6 slices slightly decreased, with weak cost support being the main factor.

Supply and demand: During the week, some polyamide filament manufacturers lowered their operating rates, resulting in a decline in overall market supply. However, industry inventory levels continued to increase, leading to poor performance on the supply side; The demand in the end market was weak, and some downstream manufacturers had reduced production or switched production, resulting in a decrease in demand for polyamide filament. It is difficult to find favorable support from the demand side, and many parties were following suit with rigid demand. Many industry players were adopting a cautious and wait-and-see attitude.

Future outlook:

Cost side: In terms of caprolactam, the expectation for benzene is weak, and slice manufacturers have low enthusiasm for purchasing caprolactam. It is expected that the caprolactam market will continue to decline next week; In terms of PA6 slicing, cost support is limited, and the supply level of PA6 slicing market may continue to improve. Downstream market demand is weak, and it is expected that the market price of polyamide PA6 slicing will decline.

Supply and demand: July belongs to the off-season of traditional demand in the market, and coupled with the lack of signs of improvement in terminal market demand, downstream market procurement enthusiasm is not high. Therefore, it is expected that the demand for polyamide filament market next month may decrease. If there is no significant improvement in demand, under the pressure of large inventory, some polyamide filament manufacturers may have the possibility of reducing production capacity, while the industry continues to release new production capacity. Therefore, it is expected that the supply of polyamide filament market will decrease next month.

Overall, both the upstream raw material caprolactam spot market and the polyamide PA6 chip market are likely to continue to decline, with a lack of cost support and difficulty in improving downstream market demand. The demand side is dragging down market trends, and under the dual negative factors, analysts from SunSirs predict that the short-term polyamide filament market prices will continue to be weak, with a expected decline of 100-300 RMB/ton.
