Fiber Ball Prices Hold Steady as Industrial Filtration Market Enters Supply-Demand Standoff

15,500 RMB per ton—this was the price quoted by Henan Kaijie Water Treatment Co., Ltd. on July 18, 2026, for ordinary fiber balls in three specifications (30mm, 40mm, 50mm). Against a backdrop of rising raw material volatility, this stability is a signal worth deeper analysis.

Cost Logic Behind the Price

Fiber balls are primarily made from polyester staple fiber (PSF), whose price is heavily influenced by crude oil, PTA, and the polyester supply chain. Since Q2 2026, international crude oil has oscillated between $70-80 per barrel, while PTA spot prices have fallen roughly 3.5% from Q1. PSF prices have only dropped about 1.2% due to divergent downstream demand, meaning fiber ball manufacturers haven't fully relieved their cost pressures. The 15,500 RMB/ton quote represents a calculated balance between protecting margins and maintaining market share.

The three specifications—30mm, 40mm, and 50mm—are primarily used in industrial wastewater, circulating water, and municipal sewage treatment, with different particle sizes corresponding to varying filtration precision and resistance. Henan Kaijie's uniform pricing suggests its production lines have achieved scale-driven changeover, diluting conversion costs. For buyers, this means no short-term price premium exists across specifications.

Industry Impact: Cross-Transmission from Water Treatment to Textiles

Fiber balls belong to the industrial textiles filtration segment. Their price trend reflects both the water treatment sector's health and indirectly signals supply-demand dynamics in upstream chemical fibers. In H1 2026, domestic water treatment investment grew approximately 8.7% year-on-year, with industrial wastewater projects accounting for over 60% of total, maintaining stable demand for consumables like fiber balls. However, downstream users have adopted a 'procure-as-needed, low-inventory' strategy, resulting in smaller, more frequent orders.

This procurement shift is forcing fiber ball producers to adjust production schedules. Quarterly stockpiling has given way to monthly or even weekly flexible scheduling, placing higher demands on PSF inventory management. Meanwhile, tightening environmental regulations on industrial wastewater discharge—such as the draft revision of the 'Discharge Standard of Water Pollutants for Dyeing and Finishing of Textile Industry'—will shorten filter media replacement cycles, long-term bullish for fiber ball demand.

Practical Recommendations

For Buyers - Monitor PSF futures trends; when PTA is at a cyclical low, consider moderately increasing fiber ball inventory to lock in cost advantages. - Request batch test reports from suppliers, comparing filtration efficiency and backwash cycle data between 30mm and 50mm specifications to avoid operational cost increases from mismatched sizing. - Establish multi-supplier price comparison mechanisms, especially tracking quotes from major production hubs like Henan and Shandong, leveraging regional price differentials to reduce procurement costs.

For Manufacturers - Optimize PSF procurement rhythm by signing short-term floating price contracts with upstream chemical fiber plants to reduce inventory devaluation risk during raw material price drops. - Develop differentiated products, such as antibacterial or high-strength fiber balls, targeting premium niches like medical wastewater and ultra-pure water for electronics. - Build a customer demand database to predict order peaks based on historical procurement cycles, adjusting capacity and raw material reserves in advance.
