In late August, the polyester filament market in Shengze presented a facade of stability, yet beneath the surface, transactions were already adjusting. Major polyester producers kept listed prices unchanged, but bulk deals commonly included discounts of 100 yuan per ton. This pattern of 'apparent stability with hidden declines' reflects a delicate balance between feedstock costs and inventory pressures across the industry.
The Truth Behind the Price Stalemate
Public ex-factory data from August 28 to 30 showed that prices for most FDY and DTY specifications remained flat, with zero fluctuation. For instance, FDY semi-dull 50D/24F was quoted at 9,800-10,000 yuan/ton by major producers like Wujiang direct-spinning plants, Xiaoshan Rongsheng, and Shenghong Chemical Fiber. DTY 75D/36F held at 10,600 yuan/ton. This apparent calm, however, masked underlying tension—the continuous pullback in PTA and MEG futures had already loosened polyester producers' pricing resolve, though not yet reflected in public listings.
This stalemate was not driven by robust demand. Industry data indicated that trading volumes were mediocre to low, with downstream weaving mills slowing their purchasing pace. Although polyester plants did not face heavy inventory pressure, the weak performance of raw materials fueled widespread caution. For buyers, this means that listed prices may not be final transaction prices, and negotiation room is quietly expanding.
Feedstock Transmission and Chain Reactions
The pricing logic of polyester filament is essentially a game of cost transmission from upstream. PTA and MEG, as core feedstocks, often lead spot prices by 3-5 trading days. The recent feedstock decline directly compressed polyester producers' profit margins but did not immediately trigger price cuts, because many plants had higher inventory costs and were reluctant to lower prices proactively. However, if feedstock weakness persists, this price-holding stance is unlikely to last more than a week.
For downstream weaving enterprises, the feedstock easing should be positive, but actual purchasing became more cautious. Two reasons: first, fear that prices have not yet bottomed out, and early restocking could lead to inventory losses; second, weak recovery in end orders, with weavers' own finished goods inventories high, prompting them to buy raw materials only as needed. This synchronized wait-and-see attitude has led to a 'price without volume' situation in the polyester filament market.
From a regional cluster perspective, Shengze, as an important hub for chemical fiber fabrics, often serves as a bellwether for price trends. If this stalemate persists, it may trigger follow-up adjustments by polyester plants in surrounding areas such as Xiaoshan, Tongxiang, and Taicang. In fact, some small and medium plants have already begun offering hidden discounts and flexible pricing to compete for orders, intensifying industry consolidation pressure.
Short-Term Outlook and Operational Strategies
Considering feedstock futures performance, inventory levels, and downstream operating rates, polyester filament prices are likely to undergo minor downward adjustments in the short term. The magnitude may be limited to 50-150 yuan per ton, mainly for conventional specifications, while differentiated products such as fully dull and high-filament-count varieties, with relatively concentrated supply, will show stronger price resilience. The primary focus for polyester spinning mills will be inventory reduction, prioritizing shipment volume over profit margins.
