A 50-yuan gap between 9,700 and 9,750 yuan per ton almost defines the entire mood of the FDY market right now. On September 15, 2026, three major Jiangsu-Zhejiang suppliers quoted 150D/96F semi-dull AA-grade FDY: Rongsheng Petrochemical at 9,700 yuan/ton, Tiansheng Chemical Fiber at 9,710, and Kaishi Group at 9,750. The spread between the highest and lowest is under 0.6% — not a coincidence, but a collective probe near the cost line across the industrial belt.
What Converging Quotes Signal
The tight clustering of quotes first indicates that pricing power in FDY is concentrating among a few leading producers. Rongsheng, as an integrated giant with self-sufficiency from PTA to polyester to spinning, sets an anchor at 9,700 yuan/ton. Kaishi and Tiansheng, quoting 10 and 50 yuan higher respectively, are following rather than leading. For buyers, the immediate consequence is shrinking bargaining room. When all suppliers hover in the same band, the traditional strategy of playing one against another loses efficiency. Procurement managers need to shift focus from pure price comparison to non-price terms such as payment periods, logistics, and batch consistency. More fundamentally, such a flat state tends to appear when the raw material side lacks clear direction. Without a trending signal from PTA or MEG futures, polyester plants have little incentive to adjust quotes proactively, preferring to hold steady and wait for downstream orders to validate demand.
Cost Transmission in the Industrial Belt
Jiangsu and Zhejiang form the core production region for polyester FDY, with Hangzhou, Shaoxing, and Xiaoshan hosting a complete chain from polymerization to texturing. Rongsheng is based in Hangzhou, while Kaishi and Tiansheng are also rooted in Zhejiang. This means their raw material procurement radius, logistics costs, and energy costs overlap heavily. Quote differences stem mainly from plant scale and management efficiency rather than locational advantage. Breaking down the cost structure, PTA and MEG account for over 80% of FDY direct costs. Maintaining quotes near 9,700 yuan/ton suggests processing fees for polyester plants have been compressed to a relatively sensitive level. If raw materials rise, plants must either pass on the increase and risk losing orders, or absorb it and erode margins — neither path is easy. Downstream weaving is equally critical. The 150D/96F semi-dull specification is mainly used for apparel fabrics and home textile linings, corresponding to the tail end of autumn orders and the start of winter orders. If weaving mills are cautious about the outlook, they will keep raw material inventories low and buy on demand, which in turn suppresses FDY transaction volumes.
Impact on Procurement and Export
Flat quotes mean different strategies for different buyers. Domestic buyers with short order cycles can treat the current price range as a short-term lock-in window. But if orders extend two months out, they need to watch raw material trends to avoid building excessive inventory at high prices. Exporters face another variable. FDY export quotes are typically based on RMB costs plus exchange rates and shipping fees. Current price stability helps with quote certainty, but overseas buyers expecting lower prices may delay orders, waiting for better levels. This game is particularly common in Southeast Asian and Middle Eastern markets. Notably, Rongsheng quotes the lowest among the three, directly linked to its highest degree of integration. For large-volume, long-cycle buyers, integrated suppliers offer advantages in supply stability and price continuity. For small-batch, multi-variety buyers, the flexibility of smaller suppliers may be more valuable.
