The polyester staple fiber (PSF) market on July 16, 2026, displayed an unusual multi-brand, multi-origin price divergence: prices for the same specification (1.56dtex*38mm, melt-spun, cotton-type) varied by up to 320 yuan/ton among different traders. This is not simple volatility but a direct reflection of mismatched inventory and demand across industrial clusters.
Regional Price Gaps: Industrial Logic
According to the latest quotes, Zhonglei brand in Huzhou, Zhejiang, was priced at 7,640 yuan/ton, while Huahong brand in Wuxi, Jiangsu, was at 7,320 yuan/ton—a gap of 320 yuan/ton. Xintuo brand in Xuzhou, Jiangsu, sat in the middle at 7,540 yuan/ton. This gradient is no coincidence: Huzhou, a key downstream processing hub for polyester, benefits from stable textile mill operating rates, supporting a brand premium. In contrast, Wuxi's earlier capacity expansion created short-term inventory pressure, forcing Huahong to cut prices.
Notably, Huaxicun brand had two quotes in the same market—7,620 yuan/ton and 7,570 yuan/ton—offered by different traders. This indicates internal channel inventory divergence: some traders discounted by 50 yuan/ton to accelerate cash recovery, while end-users leverage this information asymmetry to negotiate lower prices.
The Seesaw Effect: Fiber Balls vs. PSF
While PSF prices fluctuated, fiber balls for water treatment (30-50mm diameter) remained stable at 15,500 yuan/ton, widening the gap with PSF to nearly 8,000 yuan/ton. This highlights contrasting supply-demand dynamics: fiber balls are niche functional products with inelastic demand and concentrated suppliers (e.g., Henan Kaijie), hence low price elasticity. PSF, as a bulk textile raw material, is more sensitive to cotton substitution effects and downstream order volatility.
For buyers, this divergence means: if PSF continues to soften, some spinners may adjust formulations to increase PSF usage, potentially shrinking the substitution space for specialty fibers like fiber balls.
Industrial Cluster Reactions and Upstream-Downstream Transmission
The current pricing system reveals three key signals:
- Wuxi, Jiangsu (Huahong, Huacun) has become a price trough, with local PSF producers likely cutting output or shifting to differentiated products to ease inventory pressure.
- Huzhou, Zhejiang (Zhonglei) remains firm but must watch for cross-regional inflows of cheaper supply that could disrupt local pricing.
- Xuzhou Xintuo sits in the middle, indicating balanced order books, but if the price gap persists, it risks downstream customers shifting to Wuxi.
Downstream, cotton-type PSF primarily feeds blended yarn production. 32s polyester-cotton yarn prices have been flat for three consecutive weeks, keeping mills cautious about raw material restocking. Without sudden demand surges, PSF prices are expected to oscillate narrowly between 7,250 and 7,700 yuan/ton over the next two weeks.
