The polyester staple fiber (PSF) market is experiencing a pronounced price divergence. On July 10, 2026, industry data showed fiber balls (standard grade) holding steady at 15,500 RMB/ton, while mainstream cotton-type PSF (1.56dtex*38mm, melt-blown) ranged from 7,080 to 7,370 RMB/ton, a spread exceeding 8,000 RMB/ton. This extreme divergence reflects deep shifts in downstream demand structure.
Regional and Product Logic Behind Price Divergence
From the detailed quotations, fiber ball supply is highly concentrated in Henan Kaijie, with all three diameters (40mm, 50mm, 30mm) uniformly priced at 15,500 RMB/ton. These water-treatment fiber balls are specialty PSF with high technical barriers and customer stickiness, resulting in near-zero price competition and strong price stability.
Cotton-type PSF, conversely, shows a competitive landscape. Quotations come from multiple producing areas: Xuzhou (Xintuo at 7,330 RMB/ton), Suqian (Yida at 7,220 RMB/ton), and Wuxi (Huahong at 7,080 RMB/ton, Huaxi Village at 7,370 RMB/ton), with a spread of up to 290 RMB/ton. Huahong offers the lowest price, Huaxi Village the highest, reflecting pricing flexibility due to brand, inventory, and sales strategy differences.
Notably, the price gap between fiber balls and cotton-type PSF has widened from about 6,000 RMB/ton at the start of the year to over 8,000 RMB/ton. This means that if downstream spinning or nonwoven fabric producers attempt to substitute cotton-type PSF for fiber balls, it is technically infeasible—the two products serve entirely different purposes, and the price signal is merely a surface phenomenon.
Pressure on Cotton-Type PSF: Double Squeeze from Ample Supply and Weak Demand
Cotton-type PSF quotations generally hover around 7,200 RMB/ton, down 5%-8% year-on-year. This trend is directly linked to persistently weakening upstream feedstock PTA prices. In the first half of 2026, international oil price volatility combined with new capacity releases pushed PTA costs lower, directly undermining PSF cost support.
On the supply side, Jiangsu, as the core producing region for cotton-type PSF, sees plants like Xintuo, Yida, Huahong, and Huaxi Village operating at high capacity utilization, resulting in ample market supply. Industry data shows that domestic PSF output grew approximately 4% year-on-year in January-June 2026, while downstream textile and apparel export growth slowed to under 2%, narrowing the supply-demand gap.
More critically, demand structure is shifting. Traditional cotton-type PSF downstream sectors—pure polyester yarn and polyester-cotton blended yarn—face competition from recycled PSF and differentiated staple fibers. Recycled varieties, benefiting from cost advantages and policy support, are priced 500-800 RMB/ton lower than virgin cotton-type PSF, gradually eroding low-end market share. In contrast, high-value-added water-treatment fiber balls, due to their rigid demand in industrial filtration and wastewater treatment, exhibit extremely low price elasticity.
Practical Implications for Buyers and Exporters
The current price divergence means procurement strategies must be differentiated by product category. For cotton-type PSF, ample supply and an open downward price channel give buyers strong bargaining power. For specialty products like fiber balls, with highly concentrated supply and rigid pricing, buyers need to secure supply volumes in advance.
