A subtle yet telling signal has emerged in the polyester filament market: on July 3, Kaisi Group reduced its DTY polyester yarn (150D/48F AA semi-dull low-elastic) quotation to 9,300 yuan per ton, down 18.75 yuan from the benchmark price of 9,318.75 yuan per ton recorded on July 2 by industry data provider. After several days of price stability—both July 1 and 2 saw the same 9,318.75 yuan level—this minor adjustment could indicate a shift in supply-demand dynamics.
The Three Pressures Behind the Price Easing
The first pressure comes from upstream raw materials. While the price adjustment is modest, PTA and MEG—the direct inputs for polyester—have recently seen narrowing price ranges and insufficient upward momentum, weakening the cost support for polyester filament. When raw material costs no longer justify price increases, DTY prices become more susceptible to downstream demand.
The second pressure stems from inventory digestion at the weaving end. Data from major fabric markets such as China Textile City and Shengze shows that end-user procurement has slowed since late June. Weaving mills have adopted a cautious "buy-as-needed" strategy, avoiding bulk raw material stockpiling. This cautious sentiment has directly transmitted to chemical fiber plants, increasing the selling pressure on DTY and other filament varieties.
The third pressure is the competitive landscape of regional industrial clusters. Kaisi Group is located in the Yangtze River Delta, a core polyester filament production area with concentrated capacity in Xiaoshan, Shaoxing, and Wujiang. During a demand lull, companies often initiate small price cuts to maintain sales ratios and prevent inventory buildup. The 9,300 yuan per ton quotation is essentially a test of the market floor.
Transmission Effects Across the Supply Chain
For DTY buyers, the price easing opens up bargaining room. The previous days of price standoff had left buyers waiting for a drop; now that a clear downward signal has appeared, more companies are likely to follow suit with price cuts. If PTA prices continue to weaken over the next week, the probability of DTY prices falling below 9,300 yuan per ton will increase significantly.
For chemical fiber producers, price cuts are a double-edged sword. In the short term, they relieve inventory pressure, but if they trigger a chain reaction of price reductions, profit margins could be compressed. This is especially true for standardized products like low-elastic yarn, where price wars are difficult to reverse once started.
From an international trade perspective, the key variables affecting DTY exports are exchange rate fluctuations and the pace of overseas order recovery. The willingness of Southeast Asian textile mills to purchase Chinese DTY largely depends on whether the price difference is sufficient to cover freight and tariffs. At the current 9,300 yuan per ton level, it remains attractive to some Southeast Asian buyers, but more flexible payment and delivery terms are needed.
