The polyester staple fiber market sent a warning signal in early July: the price gap for identical specifications produced by the same process reached 410 yuan/ton across different regions. This is not a statistical anomaly but a microcosm of shifting supply-demand logic in regional industrial clusters.
Price Divergence: Three Regions, Three Logics
According to publicly available industry data on July 2, melt direct-spun cotton-type polyester staple fiber (1.56dtex×38mm) was quoted at 7,280 yuan/ton in Huzhou, Zhejiang; 7,150 yuan/ton in Suqian, Jiangsu; and only 6,870 yuan/ton in Wuxi, Jiangsu. The Wuxi quote is 5.6% lower than Huzhou, a spread that is relatively high in recent market conditions.
From a cost perspective, melt direct spinning inherently offers integrated cost advantages, but differences in raw material sourcing, energy prices, and logistics efficiency directly impact final quotes. The higher prices in Huzhou and Suqian may relate to upstream PTA/MEG procurement channels or local environmental costs, while the lower Wuxi price suggests higher inventory pressure or stronger willingness to sell among local mills.
For buyers, this spread means that refined sourcing by origin can yield direct cost savings of hundreds of yuan per ton. For a medium-sized spinning mill using thousands of tons annually, this alone can save millions of yuan.
Regional Responses: From Uniform Market to Regional Game
Traditionally, polyester staple fiber quotes showed strong regional correlation, with spreads typically within 100-200 yuan/ton. The current 410 yuan/ton gap indicates structural divergence in supply-demand matching across regions.
In the southern Jiangsu region around Wuxi, downstream weaving and garment clusters are dense, but recent operating rates have fluctuated. Some small and medium enterprises have reduced raw material inventories due to insufficient orders, forcing local staple fiber mills to cut prices to maintain shipment volumes. In contrast, Huzhou has relatively concentrated staple fiber capacity, with limited substitution demand from local filament weaving clusters, giving sellers stronger pricing power.
Suqian's middle-of-the-range quote reflects its position as an emerging fiber production base—combining cost advantages of northern Jiangsu with hidden costs from longer logistics radii.
This divergence means that the traditional "one-size-fits-all" quoting model is failing. Procurement decisions must be based on real-time, precise data on regional inventories and operating rates, not just futures prices or average indices.
