The polyester filament yarn market is navigating a delicate price equilibrium. On July 27, industry data showed quotes for polyester FDY (150D/96F, semi-dull AA grade) in two major East China production and consumption hubs both converging at 8,800 yuan per ton. The identical quotes from Rongsheng Petrochemical and Zhejiang Juxing Chemical Fiber signal not an isolated promotion but a phase consensus among leading players. This price level sits in the mid-to-low range for the year, down about 4.3% from the Q2 peak of 9,200 yuan per ton. The decline mirrors the drop in PTA spot prices, confirming that cost-side weakness is the primary driver. For weaving clusters in Shaoxing and Xiaoshan, this price means lower greige fabric costs, offering a slim profit buffer as finished fabric prices lag.
Supply-Demand Dynamics and Q3 Outlook
The current price stalemate stems from a lack of variables on both sides. On the supply side, polyester plants maintained high operating rates in July, averaging 86%, ensuring ample FDY supply. However, downstream end-markets—especially apparel fabrics and home textiles—remain sluggish during the traditional off-season, with weavers purchasing only on a need-to basis. This "stable supply, weak demand" pattern means any marginal change could break the balance. If upstream PX prices weaken further due to oil volatility, FDY prices risk a downward adjustment. Conversely, if autumn/winter orders arrive early in late August, inventory drawdown could trigger a rally. Seasonally, Q3 is a pivot point for polyester, and market expectations for the "golden September and silver October" are generally cautious this year.
Processing Margins and Industrial Transmission
At 8,800 yuan per ton, processing margins for polyester mills are razor-thin, estimated at 300-400 yuan per ton—near breakeven. This means any further price drop could force high-cost small plants to cut runs or shut down, providing a floor. For downstream weavers and dyers, this price level presents a strategic decision. Buying now locks in low raw material costs, but if Q3 orders fail to recover, inventory carrying costs could offset the advantage. The next two weeks' weaving operating rates and sample orders for autumn/winter fabrics will be decisive.
