Divergence in Polyester Staple Fiber Prices: Industrial Fibers Remain Firm While Spinning Grades Face Downward Pressure

On June 26, the polyester staple fiber market sent a warning signal: prices within the same raw material category are diverging sharply. Industrial-grade fiber balls (e.g., Henan Kaijie 30-50mm diameter) held steady at 15,500 RMB/ton, while spinning-grade polyester staple fiber (Yida 1.56dtex*38mm cotton-type) in Suqian, Jiangsu, dropped from 7,330 to 7,250 RMB/ton. The price gap of over 8,000 RMB reflects not just specification differences but a structural divergence in downstream demand.

Industrial Demand Supports Fiber Ball Prices

Industrial fiber balls maintain high prices due to rigid demand in water treatment, oil field extraction, and air filtration. These sectors require continuous procurement and high product consistency. Henan Kaijie, a major supplier, quoted the same 15,500 RMB/ton for diameters 30mm, 40mm, and 50mm, indicating low price sensitivity among industrial users who prioritize quality and supply reliability.

Industry data shows that domestic industrial water treatment project investment grew about 12% year-on-year in the first half of 2026, while oil field chemical demand remained stable. These factors provide a solid floor for fiber ball prices. Unless environmental regulations or industrial capacity utilization drop sharply, this price range is unlikely to weaken.

Spinning-Grade Staple Fiber Under Pressure

In contrast, spinning-grade polyester staple fiber faces downward pressure from weak end-consumption. Yida's 1.56dtex*38mm cotton-type fiber in Suqian fell 80 RMB/ton in a single day, a 1.1% drop that, though modest, challenges spinners' cost control in a low-margin environment.

The root cause is sluggish textile consumption. Export orders for garments are slowing, and domestic demand lacks momentum, leading to low mill operating rates and inventory-focused raw material purchases. China Customs data shows textile and apparel exports fell 3.2% month-on-month in May 2026, with year-on-year growth narrowing to 1.5%. This weak demand forces suppliers to cut prices to compete for limited orders.

Regional and Channel Price Gaps Widening

Notably, Zhejiang Tianchen, a trading company, quoted two different prices for the same Yida fiber: 7,330 and 7,250 RMB/ton. This likely reflects differences in delivery terms, payment conditions, or order size, not mere confusion. It signals that market liquidity is low, and price elasticity across channels is increasing.

Regionally, Zhengzhou, Henan, as a fiber ball hub, shows stable pricing, while Suqian, Jiangsu, a spinning-grade fiber production center, experiences more frequent fluctuations. Buyers should monitor regional spreads and consider cross-regional price comparisons for better costs.

Practical Recommendations

For Buyers - Clarify fiber end-use: Industrial fiber balls and spinning-grade staple fiber serve different applications. Confirm the final use before purchasing to avoid waste from mismatched specifications. - Focus on regional spreads: Spinning-grade fiber prices in Suqian are under downward pressure; prioritize negotiations with local suppliers. For fiber balls, lock in stable suppliers like Henan Kaijie to ensure quality consistency. - Leverage price flexibility: Traders like Zhejiang Tianchen show pricing flexibility. For large orders, consider batch purchasing or negotiate volume discounts.

For Mills (Production Side) - Optimize product mix: If spinning-grade fiber margins continue to shrink, consider shifting some capacity to industrial fiber balls or differentiated products to enhance risk resilience. - Control inventory cycles: With spinning-grade raw material prices still in a downtrend, keep inventory cycles to 7-10 days to avoid further mark-to-market losses. - Strengthen regional cooperation: Mills near Suqian can form joint purchasing groups to boost bargaining power, or sign short-term floating price agreements with downstream yarn mills to lock in partial orders.
