The price of water treatment fiber balls remains stable at 15,500 RMB per ton, a figure that stands out in the current polyester staple fiber market landscape. Compared with conventional textile-grade polyester staple fiber, the water treatment specialty grade commands a premium of 30%-40%, reflecting the pricing power of differentiated products in specific application scenarios.
Background
Industry pricing data released on July 11, 2026, shows that Henan Kaijie Water Treatment Co., Ltd. quoted fiber ball products in three diameters—30mm, 40mm, and 50mm—all at 15,500 RMB per ton, delivered in Zhengzhou, Henan Province. This quotation is not an isolated case but a snapshot of the water treatment polyester staple fiber price center over the past three months.
On the raw material side, upstream PTA and MEG prices saw a slight correction at the end of the second quarter, but water treatment fiber ball prices did not move in tandem. Public industry data indicates that in the first half of 2026, the average price of domestic water treatment fiber balls stayed in the 14,800-15,500 RMB per ton range, up about 8% year-on-year from 2025. This price resilience is underpinned by growing industrial wastewater treatment demand driven by stricter environmental policies.
Industry Impact
The high price level of water treatment fiber balls has multiple transmission effects on the polyester staple fiber supply chain. First, for upstream chemical fiber companies, it means that differentiated product lines can effectively hedge against profit fluctuations from conventional grades. In the first half of 2026, conventional polyester staple fiber saw per-ton profits squeezed to 200-300 RMB due to overcapacity, while the water treatment specialty grade achieved per-ton profits of 800-1,200 RMB.
Second, from a regional industrial cluster perspective, Zhengzhou, Henan, as the delivery point for this quotation, reflects the strengthening role of the central region in water treatment material distribution. Traditionally, polyester staple fiber industrial clusters are concentrated in Shengze (Jiangsu), Keqiao (Zhejiang), and Changle (Fujian). However, production and warehousing of water treatment fiber balls are beginning to shift toward regions closer to end markets, such as Henan and Shandong. This industrial layout adjustment means logistics costs and delivery lead times are becoming new competitive variables.
For downstream water treatment engineering firms, the 15,500 RMB per ton price level requires upward revisions in project procurement budgets. For an industrial wastewater treatment plant with a daily capacity of 50,000 tons, the cost of replacing fiber ball filter media could increase by 15%-20%. This in turn stimulates R&D into recyclable fiber balls and washable fiber balls.
