On June 26, 2026, the spot price range for polyester FDY 150D/96F semi-dull grade in East China was only 250 RMB per ton—from 8,500 to 8,750 RMB. Compared with the volatile swings of the past two years, this narrow band signals a market entering a rare period of tight fluctuation.
Market Signals from Price Convergence
Among the six major suppliers reporting prices that day, Rongsheng Petrochemical and Zhejiang Juxing Chemical both quoted 8,500 RMB/ton, Zhejiang Jiabao New Fiber quoted 8,510 RMB, Hangzhou Kaishi Group quoted 8,650 RMB, Tiansheng Chemical Fiber quoted 8,710 RMB, and Tongkun Group quoted 8,750 RMB. All quotes fell within the 8,500-8,750 RMB range, with no outliers below 8,500 or above 8,800.
This price convergence was uncommon during 2024-2025, when intra-month spreads often exceeded 500 RMB/ton due to crude oil volatility and mismatched downstream demand. The current 250 RMB spread indicates a consensus between buyers and sellers on short-term price expectations.
On the supply side, top players like Rongsheng and Tongkun quoted at the upper end, reflecting their cost advantages and pricing power with premium customers. Mid-sized firms like Juxing and Jiabao quoted near the lower end, suggesting they are prioritizing order volume over price in a period of moderate order book saturation.
Dual Squeeze from Costs and Demand
The narrow FDY price range is underpinned by a lack of directional moves in upstream raw materials PTA and MEG. Profit compression in the PX chain has passed through to PTA, stabilizing polyester plants' input costs. Meanwhile, downstream weaving has entered a traditional off-season, with loom utilization in Jiangsu and Zhejiang hovering around 70%, resulting in mostly hand-to-mouth purchasing and low speculative inventory building.
Notably, the quoting locations—Hangzhou, Shaoxing, and Jiaxing—are the most concentrated polyester filament production hubs in China. The near-simultaneous price movements across these companies reflect high information transparency and strong price linkage within the industrial cluster. A price change by one firm is typically matched by others within 24 hours.
Practical Implications for Buyers and Mills
This narrow-band environment creates distinct operational strategies for different supply chain participants.
For Buyers - The current price range offers a clear cost anchor; adopt a just-in-time purchasing approach rather than waiting for further declines. - Focus on the monthly settlement policies of top suppliers like Tongkun and Rongsheng, which often provide additional discounts for bulk orders. - Consider consolidating purchase intervals to lock in feedstock costs for the next two weeks while prices remain stable.
For Mills (Chemical Fiber Producers) - Narrow volatility reduces inventory management complexity but also compresses profit margins, necessitating further non-raw-material cost reductions. - Differentiated products (e.g., cationic dyeable or flame-retardant FDY) command higher premiums than standard 150D; prioritize their production scheduling. - Closely monitor demand changes in July-August as downstream mills begin sampling for autumn/winter fabrics, which may reopen the price range.
Overall, the polyester FDY market has transitioned from the sharp volatility of 2024 to a consolidation phase in mid-2026. For industry participants, the key is no longer betting on directional moves but accurately calculating the marginal cost and marginal return per ton of product.
