In early July 2026, the polyester staple fiber spot market posted a revealing set of prices: Zhonglei brand from Huzhou, Zhejiang at 7,280 yuan/ton, Yida brand from Suqian, Jiangsu at 7,150 yuan/ton, and Huahong brand from Wuxi at only 6,870 yuan/ton. The maximum spread among the three reached 410 yuan/ton, 1.5 times the average level of the past six months.
Industrial Logic Behind Price Divergence
On the surface, this is a routine daily price update. But examining the brand-origin combinations reveals three distinct industrial niches. Zhonglei's highest price reflects its location in Zhejiang, close to downstream spinning clusters—short transport distances and strong customer loyalty command a premium. Yida, based in Suqian in northern Jiangsu, a new production capacity zone, has longer logistics radii but possibly lower raw material costs, placing its quote in the middle. Huahong, in Wuxi, a traditional southern Jiangsu production area, posted the lowest price, suggesting temporary destocking pressure in that region.
This regional price structure is not a short-term phenomenon. Over the past year, new polyester staple fiber capacity has concentrated in northern Jiangsu and Anhui, away from traditional producing areas, while downstream spinning clusters remain mainly in Zhejiang and southern Jiangsu. The resulting supply-demand mismatch has increased the weight of logistics costs in final pricing. For the same specification and quality grade, the actual landed cost difference between different delivery points can exceed 500 yuan/ton.
Real Impact on Downstream Buyers
For spinning mills, a spread of over 400 yuan means raw material costs can vary by nearly 6%. Given that cotton-type polyester staple fiber accounts for 30%-40% of spinning raw material costs, this gap directly affects product gross margins. Small and medium mills, with tight cash flows, make procurement decisions on a weekly basis, and price volatility directly transmits to order quotes.
Industry data shows the polyester staple fiber operating rate is around 78%, but regional divergence is clear: in Zhejiang, strong downstream demand keeps factory inventory at just 5-7 days, while some new lines in northern Jiangsu, struggling with customer development, have inventory of 12-15 days. This explains why different brands using the same melt-spinning process adopt such different pricing strategies.
Hidden Concerns and Opportunities in Chain Transmission
More importantly, this price spread is transmitting upstream to raw material markets. PTA and ethylene glycol price fluctuations were once the main cost drivers, but regional supply-demand mismatches are now becoming a new pricing factor. For traders, this means greater arbitrage opportunities—buying in low-price regions and selling in high-price regions, net of logistics costs, remains profitable. But the risk is that once regional supply-demand dynamics shift, the spread may quickly narrow or even reverse.
For textile exporters, regional cost differences mean products from different origins have different international competitiveness. FOB quotes at East China ports are typically based on southern Jiangsu prices, but if northern Jiangsu capacity continues to expand and offer lower prices, the raw material source for export orders may shift northward.
