A rare pricing signal has emerged in the market for PET staple fiber balls used in water treatment: one supplier quoted identical prices for three different specifications. On July 12, 2026, Henan Kaijie Water Treatment Co., Ltd. priced ordinary fiber balls in diameters of 30mm, 40mm, and 50mm uniformly at RMB 15,500/ton. This 'no-differential' pricing strategy, against a backdrop of high raw material costs and cautious downstream procurement, reveals important industry signals.
Price Stalemate: Balancing Cost Pass-Through and Demand Resilience
The RMB 15,500/ton quote is not an outlier. Industry data show that prices for water-treatment PET staple fiber balls have remained in the range of RMB 15,000-16,000/ton since Q2 2026. Polyester raw materials PTA and MEG rose over 12% in the first half of the year, directly pushing up production costs. Henan Kaijie's uniform pricing is essentially an attempt to pass on raw material cost pressure downstream.
However, the identical pricing for three common specifications (30mm, 40mm, 50mm) defies conventional logic. Typically, larger-diameter fiber balls use more material per unit and should cost more. This uniform pricing may indicate that the supplier is actively compressing profit margins to maintain sales volume, or that downstream customers are becoming less sensitive to specification differences and more focused on overall cost-effectiveness.
Industrial Cluster Response: Central China's Water Treatment Material Concentration
Henan Kaijie, based in Zhengzhou, Henan Province, is part of the central China water treatment materials industrial cluster. This region hosts numerous fiber ball, filter media, and filler manufacturers. Leveraging proximity to raw material sources (e.g., Luoyang Petrochemical, Zhongyuan Petrochemical) and logistics hubs, it dominates the northern water treatment market.
The stability of this quote reflects a common dilemma faced by enterprises in the cluster: upstream polyester raw material prices are prone to rise but hard to fall, while downstream procurement budgets for municipal sewage plants and industrial wastewater treatment facilities have not increased synchronously. For fiber ball producers in Zhengzhou and surrounding areas, RMB 15,500/ton may represent the 'psychological floor' for maintaining reasonable profits. A drop below this level would force some small and medium-sized enterprises to sell at a loss.
Impact on Buyers: The Window for Price Lock-In Is Narrowing
For procurement managers at water treatment engineering companies and environmental equipment integrators, the current price environment presents two key judgments:
First, short-term downside is limited. Raw material cost support remains intact, the PX-PTA maintenance season is not over, and PET staple fiber operating rates hover around 78%, with no significant oversupply pressure.
Second, a price inflection point may arrive around the end of Q3 to early Q4. According to industry data, new domestic PET staple fiber capacity is expected to come online around September 2026, significantly increasing supply and likely pushing fiber ball prices down from current highs.
For Procurement Managers - For near-term rigid demand, consider phased purchasing at current levels to avoid project cost overruns from sudden raw material spikes. - Monitor capacity release signals at the end of Q3. If PTA maintenance ends and new units start smoothly, consider delaying large orders until October. - Request a detailed 'specification-price' breakdown from suppliers to avoid uniform pricing masking true cost differences across specifications.
For Export Enterprises - The current domestic price of RMB 15,500/ton translates to approximately USD 2,150/ton FOB, still competitive compared to similar products from Southeast Asia. - For export orders, consider adopting a 'monthly price adjustment' clause to share raw material price fluctuation risks with clients. - Focus on water treatment project tenders in emerging markets like the Middle East and Africa, where price sensitivity is high and Chinese products currently offer a cost advantage.
Overall, the 'high-level stalemate' in the fiber ball market will not last long. With new capacity releasing at the end of Q3, a return to a more rational price range is highly probable. Procurement managers and export enterprises should use this window to optimize inventory management and contract terms.
