Polyester FDY Price Divergence: A Signal of Profit Redistribution in the Polyester Chain

Beneath the calm surface of the polyester filament market, currents are shifting. On June 26, 2026, public quotes for polyester FDY 150D/96F semi-dull AA-grade widened to a 250 CNY/ton range—from Tongkun Group's 8,750 to Rongsheng Petrochemical and Zhejiang Juxing's 8,500, a 2.9% spread. For a highly standardized chemical fiber grade, this dispersion is no coincidence but a direct projection of imbalanced profit distribution along the chain.

Quote Dispersion: Mirror of Costs and Inventories

The divergence first stems from differences in raw material cost transmission. PTA and MEG experienced a volatile up-and-down cycle in June, but varying procurement timings and contract pricing models among producers resulted in a 200-300 CNY/ton cost gap. Rongsheng and Juxing's 8,500 quote reflects cost advantages locked in during lower raw material prices, while Tongkun's 8,750 suggests higher inventory costs or a bullish outlook.

A deeper factor is inventory pressure. Public industry data shows FDY factory inventories in Jiangsu and Zhejiang climbed to 18-22 days by mid-June, up 3-5 days from May. Hangzhou-based Tiansheng Chemical's 8,710 quote sits in the mid-to-high range, consistent with its above-95% operating rate and faster inventory turnover. In contrast, Shaoxing-based Juxing's aggressive 8,500 quote likely aims to destock and free up cash.

Regional Industrial Belt Differentiation

The quote dispersion also reveals varied competitive dynamics across industrial belts. Hangzhou and Shaoxing, as China's two core polyester filament production hubs, show divergent pricing strategies. Hangzhou producers (Rongsheng, Tongkun, Tiansheng) quote between 8,650-8,750, generally higher, reflecting their upstream PTA integration and stronger risk resilience.

Shaoxing producers (Juxing, Jiabao) cluster around 8,500-8,510, significantly lower. The region's many small-to-medium enterprises rely heavily on external raw material procurement, making cost control weaker during PTA volatility, thus more inclined to cut prices for orders. This "Hangzhou stable, Shaoxing falling" pattern fundamentally reflects differences in chain integration.

Downstream Transmission Effects

For downstream weaving mills, FDY quote dispersion increases procurement opportunities. But the 250 CNY/ton spread also carries risk: low-priced supply may reflect distressed inventory clearance—once raw materials rebound, these suppliers could quickly raise prices or cancel orders. Buyers must distinguish between "cost-driven low prices" and "inventory-driven low prices."

From a macro perspective, widening FDY quote dispersion often precedes profit redistribution along the polyester chain. When PTA and MEG stay elevated but end demand cannot keep pace, intermediate FDY/POY/DTY margins are inevitably squeezed. In H1 2026, average FDY processing spread narrowed from 1,200 CNY/ton at the start of the year to around 850 CNY/ton in June, with some small producers approaching breakeven.

Practical Recommendations

For Buyers - Prioritize integrated producers (e.g., Rongsheng, Tongkun) for more stable pricing and lower supply chain risk. - For low-priced supply around 8,500 from Shaoxing, request recent quality inspection reports and clear delivery timelines to avoid quality or lead-time issues from distressed inventory. - Build a supplier list with 3-5 price tiers, and execute batch procurement within the 250 CNY/ton spread to reduce speculative risk per order.

For Exporters - Use a "PTA + processing fee" floating formula in export contract pricing to avoid confusion from domestic FDY quote dispersion. - Monitor Hangzhou vs. Shaoxing quote indices; when quoting to Southeast Asian or South Asian clients, prioritize integrated producer prices as benchmarks. - Leverage the current spread window to sign short-term price-lock agreements with low-priced suppliers, but cap lock-in periods at 15 days to hedge against raw material rebound risk.
