A mere 50 yuan per ton — that was the price gap between two leading polyester FDY producers on September 11, 2026. Rongsheng Petrochemical quoted 9,700 yuan/ton, while Kaishi Group quoted 9,650 yuan/ton, both for 150D/96F semi-dull AA-grade filament. For melt-spinning plants with daily output in the hundreds of tons, such a thin spread is almost no spread at all. This is not coincidence; it is the result of cost transparency and order competition converging.
Price Signal: The Psychological Battle at the 10,000-Yuan Threshold
Polyester FDY mainstream quotes are approaching the 10,000-yuan mark but have not yet broken through. According to industry public data, the 150D/96F specification is a benchmark whose price elasticity directly reflects the operating willingness of downstream warp-knitting and water-jet loom mills. The 50 yuan/ton gap between Rongsheng and Kaishi indicates that leading producers in the Zhejiang market have highly overlapping pricing power — whoever cuts first risks triggering a chain reaction.
For buyers, this narrow spread means very limited room for negotiation. The traditional strategy of pitting suppliers against each other has lost effectiveness, because the two companies' delivery costs, settlement methods, and credit terms have become largely homogeneous. What truly influences procurement decisions is no longer the unit price itself, but delivery cycles and batch consistency.
Why has the spread narrowed to this extent? The core reason is that spot price fluctuations of PTA and ethylene glycol have moderated, making raw material cost curves highly consistent across melt-spinning producers. When upstream cost differences are erased, finished product quotes naturally converge toward the middle. This also means that the future direction of FDY prices depends more on demand than on cost.
Industrial Transmission: Order Temperature from Hangzhou to Keqiao and Shengze
Hangzhou, home base of both Rongsheng and Kaishi, serves as a bellwether for the two major fabric industrial belts in Keqiao, Shaoxing, and Shengze, Suzhou. Warp-knitting enterprises in Keqiao and water-jet loom mills in Shengze are the primary consumption channels for 150D/96F, used to produce medium-to-heavy fabrics such as luggage cloth, tent fabric, and advertising lightbox material.
The current quote holding steady in the 9,650-9,700 yuan/ton range suggests that rigid demand from weaving mills continues, but large-scale stockpiling intentions remain weak. From a supply chain transmission perspective, if FDY prices stay flat for two consecutive weeks, weaving enterprises tend to maintain low-inventory operations and purchase on order. Once a clear downward signal emerges, it could instead trigger a round of concentrated restocking.
It is worth noting that Kaishi Group's quote is slightly lower than Rongsheng's, possibly reflecting a higher share of export orders in its customer structure and greater sensitivity to exchange rate fluctuations and export freight. For foreign trade enterprises, FDY costs typically account for 55%-65% of fabric ex-factory prices. A 50 yuan/ton spread translates to less than 0.02 yuan per meter of fabric — almost negligible. This means that at the current stage, the competitiveness of export quotes depends more on weaving efficiency and delivery management than on marginal differences in raw material procurement.
Trend Assessment: The Longer the Sideways Move, the Closer the Breakout
Historically, polyester FDY's sideways period near the 10,000-yuan threshold rarely exceeds three weeks. Since the third quarter of 2026, the textile industry has been in a pattern of "off-season not off, peak season not peak," with downstream apparel brands placing fragmented orders, leaving weaving mills reluctant to stockpile.
If FDY quotes remain in the 9,650-9,700 yuan/ton range for another week, the market will enter a silent period before directional selection. For factories, the worst moves now are blind capacity expansion or significant price concessions. A reasonable strategy is to lock in some forward raw material, maintain stable operating rates, and prioritize high-margin orders with tight delivery schedules.
For buyers, the current price level sits in the mid-to-lower range of the year, offering a certain safety margin. However, be alert: once crude oil prices move unexpectedly or PTA plants undergo concentrated maintenance, FDY cost support will strengthen rapidly, and the 10,000-yuan threshold could be breached quickly.
