This week, the polyester filament market as a whole showed a weak downward trend, with a slight shift in price focus. As of October 17th, the mainstream polyester filament factories in Jiangsu and Zhejiang have quoted POY (150D/48F) at 6400-6700 yuan/ton, polyester DTY (150D/48F low elasticity) at 7750-8000 yuan/ton, and polyester FDY (150D/96F) at 6500-6800 yuan/ton.
Weakened cost support
The recent decline in international oil prices has weakened the cost support of polyester filament. At the same time, market concerns about US tariff policies have intensified market panic.
Rising inventory pressure
After the National Day holiday, the inventory of polyester filament continued to accumulate. As of October 9th, the average inventory in the industry has reached about 22 days, including POY for about 13-14 days, FDY for about 24 days, and DTY for about 29 days. High inventory levels make factories strongly willing to ship, and they tend to alleviate pressure by offering discounts and promotions.
The demand side continues to be sluggish
Downstream weaving enterprises are very cautious in procurement, mainly focusing on replenishing inventory for essential needs, and have a weak willingness to stock up in large quantities. At the same time, there is also uncertainty in the external trade environment. Although Trump’s attitude has softened after his tough stance, the high comprehensive tariff rate still poses a challenge to the sustained recovery of textile export orders.
Considering factors such as insufficient cost support, high inventory, and low downstream purchasing willingness, it is expected that the price of polyester filament will continue to fluctuate weakly in the short term. The prices of some varieties with high inventory pressure may continue to decline slightly.
