In late August, the polyester filament market in Shengze fell into a rare stalemate: mainstream specifications held prices steady for two consecutive days, yet bulk transaction prices quietly flexed. The cost pullback from PTA and MEG futures collided with polyester plants' modest inventories, leaving the market oscillating between 'discounting to move goods' and 'holding prices to wait'. This surface calm may warrant more caution than a one-way rally or decline.
Background
From August 29 to 30, filament prices showed a pattern of 'firm quotes, flexible deals'. According to public industry data, mainstream FDY semi-dull specs such as 40D/12F and 50D/24F held flat, with a major Wujiang mill quoting 10,300 and 10,000 yuan/ton respectively; DTY 75D/36F stayed at 10,600 yuan/ton. However, some polyester producers offered discounts of around 100 yuan/ton for large orders, making actual transaction prices notably more negotiable.
The cost side is the direct trigger. PTA and MEG futures pulled back, weakening support for filament prices, but polyester plants' inventories were not burdensome, so there was little incentive for aggressive cuts. This combination of weak feedstock and low inventory pushed both upstream and downstream into wait-and-see mode: polyester mills hesitated to cut margins, while weavers waited for a cheaper entry point.
Industry Impact
Feedstock volatility is slowly transmitting down the chain. For polyester plants, the core dilemma is 'protect profit' vs. 'protect cash flow'. Low inventories mean no urgent need to dump stock, but if feedstock keeps weakening, inventories produced from earlier high-cost raw materials face depreciation risk, and a passive price cut might hurt more than an active one. Hence, many mills choose 'stable on the surface, flexible underneath', testing downstream acceptance with negotiable prices.
For weavers, price stagnation is not necessarily good. Buyers generally expect further dips, so they postpone restocking and keep raw material inventories lean, which in turn intensifies pressure on polyester mills to ship. Major weaving hubs like Shengze, Xiaoshan, and Tongxiang have not seen significant drops in operating rates, but new orders are mostly small, need-based lots, with few bulk orders. This 'buy on rising, not falling' psychology is amplified during weak feedstock cycles.
Notably, price gaps across specifications and origins are narrowing. For FDY semi-dull 75D/36F, Shaoxing Tiansheng and Shenghong both quoted 9,400 yuan/ton, while Tongkun and Xinfengming quoted 9,500 yuan/ton—a gap of only 100 yuan. This indicates that in a sluggish demand environment, brand premiums and regional differences are compressed, pushing price competition toward homogenization. For buyers, this actually creates comparison opportunities—the price difference across mills for the same spec may offer more actionable value than simply waiting for a market-wide drop.
