On July 2, 2026, spot pricing for polyester staple fiber (PSF) revealed a noteworthy signal: the price spread for the same specification (1.56dtex*38mm, melt-spun cotton type, premium grade) across different production regions has widened to 410 yuan/ton. Huahong brand in Wuxi, Jiangsu was quoted at 6,870 yuan/ton, Zhonglei brand in Huzhou, Zhejiang at 7,280 yuan/ton, and Yida brand in Suqian, Jiangsu at 7,150 yuan/ton. This spread structure, more than a single price movement, reveals the current state of the chemical fiber supply chain.
The Capacity Game Behind the Spread
On the surface, this is a regional price difference among brands and delivery locations. But deeper analysis shows that the three quotation points correspond to two key zones of China's PSF capacity distribution: southern Jiangsu (Wuxi) and northern Jiangsu (Suqian), plus northern Zhejiang (Huzhou). Southern Jiangsu has long been a dense area for PSF production, where companies in Jiangyin and Wuxi face intense competition and chronically low capacity utilization. When the industry enters an oversupply phase, companies in this region tend to cut prices aggressively to maintain cash flow.
Huzhou Zhonglei's quotation is 410 yuan/ton higher than Wuxi Huahong, not because of a fundamental quality difference—both are premium-grade cotton-type products with identical specifications. The core difference lies in Huzhou's relatively concentrated PSF capacity, giving local producers stronger bargaining power. Additionally, northern Zhejiang's downstream weaving and garment clusters provide more robust demand support for staple fiber, reducing the need for aggressive price cuts to clear inventory. Suqian Yida's mid-range price reflects its position as an emerging capacity recipient: clear cost advantages but still-developing logistics infrastructure.
Real Impact on Downstream Spinning Mills
What does this spread structure mean for downstream spinning mills? First, procurement decisions become significantly more complex. In the past, purchasing managers only needed to focus on absolute price levels. Now, they must balance price, supply stability, logistics costs, and delivery timeliness. Choosing lower-priced southern Jiangsu sources can reduce per-ton raw material costs by approximately 6%, but carries the risk of supply concentration—if local companies cut output or shut down due to cash flow problems, raw material supply could tighten instantly.
Second, the widening spread also signals accelerating industry consolidation. The companies offering the lowest prices in southern Jiangsu are often those with the highest debt ratios and greatest financial pressure. Their low-price strategy is essentially "volume for price," sacrificing margins to maintain utilization rates and market share. For buyers, this means conducting deeper due diligence on supplier financial health to avoid production interruptions from sudden supplier shutdowns.
Price Expectations Under the Capacity Cycle
Looking at the longer cycle, the PSF industry is in a classic overcapacity phase. After a concentrated release of new capacity in 2024-2025, industry operating rates have fallen from above 85% to around 75%. Against this backdrop, the widening regional spread is not a short-term phenomenon but a long-term feature of the industry's transition from "high profit, high growth" to "low profit, differentiated competition." Over the next 12 months, some high-cost capacity in southern Jiangsu is expected to be forced out, while regions with cost or demand advantages, like northern Zhejiang and northern Jiangsu, will maintain relatively firm pricing.
