The polyester staple fiber market is undergoing a structural divergence in regional pricing. According to publicly available industry data from July 3, 2026, the price gap for cotton-type polyester staple fiber of the same specification between different producing regions has exceeded 400 CNY/ton. Special-grade fiber balls are priced at more than double the level of standard staple. This tiered pricing is not a short-term fluctuation but a result of capacity distribution, logistics costs, and downstream demand structure.
Regional Pricing and Capacity Logic
From the quotes, Huahong brand (Wuxi, Jiangsu) offered 6,940 CNY/ton for 1.56dtex*38mm, while Zhonglei brand (Huzhou, Zhejiang) offered 7,320 CNY/ton for the same spec, a spread of 380 CNY/ton. Xintuo (Xuzhou, Jiangsu) at 7,200 CNY/ton and Yida (Suqian, Jiangsu) at 7,150 CNY/ton both undercut Zhejiang prices. This comparison reveals a key fact: Jiangsu, as a polyester capacity hub, benefits from ample local supply and competitive ex-factory prices; Zhejiang, with relatively limited local capacity and reliance on inter-provincial transfers, incorporates higher transportation costs.
What does this spread mean for buyers? For a spinning mill consuming over 1,000 tons annually, a 380 CNY/ton gap translates into hundreds of thousands of yuan in raw material cost differences. If a company's warehouse or factory is near the Jiangsu-Zhejiang border, choosing Jiangsu supply can yield significant logistics savings—provided product quality is consistent, as the "first-grade" standard quoted needs to be verified upon delivery.
Fiber Ball Prices: Water Treatment Demand as an Independent Variable
Unlike the moderate fluctuation in cotton-type staple, fiber ball prices remained stable at 15,500 CNY/ton, more than double the standard staple. Fiber balls are used as water treatment media, with demand logic entirely different from textiles. Municipal wastewater upgrading and industrial zero-discharge policies are driving sustained market expansion. Henan Kaijie's quotes for diameters from 30mm to 50mm are identical, indicating pricing is based on material and processing rather than size.
The sustainability of this price level warrants attention. If water treatment sector sentiment remains high, the premium may attract some polyester staple producers to switch production. However, conversion requires modification of cutting and crimping equipment, not achievable immediately. In the short term, the fiber ball market will remain seller-favorable, and downstream water treatment contractors should lock in long-term orders early.
Implications for Procurement Timing
The current market presents a "two ends high, middle stable" pattern: high-end specialty products are firm, low-end commodities are competitive, and mid-range products track feedstock costs. Buyers should monitor two key variables:
- Crude oil and PTA trends: Polyester staple costs are highly dependent on upstream petrochemicals. If crude trends downward, Jiangsu producers may have more room to cut prices than Zhejiang producers.
- Regional inventory levels: Some Jiangsu plants are near breakeven, limiting further cuts; Zhejiang supply may stay relatively high due to rigid logistics costs.
