The same specification of polyester staple fiber can differ by nearly 300 yuan per tonne between Wuxi, Jiangsu, and Huzhou, Zhejiang — a spread wider than the per-tonne net profit of many traders. According to China Customs and industry public data, in mid-September 2026, mainstream cotton-type 1.56dtex melt-spun polyester staple fiber traded in a range of 8,470 to 8,750 yuan per tonne, but the regional price structure is undergoing subtle yet critical changes.
Spread Structure: More Than a Simple Origin Premium
Public quotes show that Zhonglei brand from Huzhou, Zhejiang, is priced at 8,720 to 8,730 yuan per tonne, Xintuo from Xuzhou, Jiangsu, at around 8,670 yuan per tonne, while Huahong from Wuxi, Jiangsu, is quoted at only 8,470 yuan per tonne — a 200 yuan per tonne spread within the same province. This divergence cannot be explained by brand premium or logistics costs alone.
A more reasonable interpretation is that plant operating rates, inventory levels, and order structures differ between Subei and Sunan. Some Wuxi plants may face periodic inventory buildup, selling at lower prices to recover cash, while Huzhou and Xuzhou enterprises, relying on differentiated customer bases, hold firmer quotes. For buyers, this means the profit space from cross-regional price comparison is expanding, but the risk of quality consistency in low-priced supply sources also warrants caution.
Meanwhile, fiber balls for water treatment in Zhengzhou, Henan, are quoted at 15,500 yuan per tonne, following a completely different pricing logic from textile-grade staple fiber. This reminds the market that polyester staple fiber application scenarios are becoming segmented, and the price gap between industrial-grade and textile-grade products will persist.
Industrial Belt Transmission: Restocking Rhythm in Shengze and Keqiao Disrupted
The direct downstream of polyester staple fiber is cotton-type yarn, and yarn distribution hubs are concentrated in Shengze, Keqiao, Nantong, and other industrial belts. The current widening of regional spreads has directly impacted downstream factories' raw material procurement strategies.
Traditionally, yarn mills prefer nearby procurement to reduce logistics costs and response time. But when the spread exceeds 150 yuan per tonne, the economics of cross-regional sourcing become apparent. Some Shengze yarn mills have begun inquiring about low-priced supply from Subei, which could force quotes in Jiangsu-Zhejiang production hubs to soften.
Another noteworthy signal is the restocking rhythm. Since the third quarter of 2026, downstream weaving enterprises have generally adopted a "small batch, multiple batches" procurement strategy, highly sensitive to raw material price fluctuations. With regional spreads widening, factories tend to wait for low-price windows rather than restock according to plan. If this wait-and-see sentiment persists, it could further suppress transaction volumes in staple fiber.
From an industrial chain transmission perspective, staple fiber price divergence will ultimately transmit to grey fabric and finished fabric segments. If low-priced staple fiber flows into the market, yarn costs decline, and grey fabric quotes may come under pressure; conversely, if mainstream plants successfully hold prices, cost support will be maintained. The market is currently in a tug-of-war between these two forces.
Cost and Demand: Which Way Does the Balance Tip?
The cost side of polyester staple fiber is mainly affected by PTA and ethylene glycol prices. Industry public data shows that PTA processing fees have recently remained low, ethylene glycol port inventories are neutral, and the cost side lacks strong upward momentum. This means the upside for staple fiber prices is limited, and regional spreads are driven more by supply-demand mismatches than cost factors.
On the demand side, the pattern is "stable domestic demand, divergent external demand." Domestic weaving enterprises' operating rates remain at a medium level, with no obvious explosion in home textile and apparel fabric orders; in foreign trade, some export markets are affected by exchange rate and freight fluctuations, and ordering rhythms tend to be cautious. For staple fiber suppliers, this means competition for existing orders will intensify, and regional quote divergence may become the norm rather than a short-term phenomenon.
It is worth noting that the spread between recycled and virgin polyester staple fiber is also narrowing. With the advancement of environmental policies and brand sustainable procurement requirements, recycled staple fiber demand is resilient, and some downstream customers are willing to pay a premium for recycled materials. This trend poses a long-term challenge to the pricing power of virgin staple fiber.
