The same specification of polyester DTY, quoted by five major suppliers in Zhejiang on the same day, can differ by 460 yuan per ton. That is not a rounding error — it is a real spread wide enough to determine the profit or loss of an entire order. On September 11, 2026, for the standard specification of 150D/48F semi-dull low-elasticity DTY, premium grade, Zhejiang Juxing Chemical Fiber quoted 10,100 yuan per ton, Rongsheng Petrochemical quoted 10,550 yuan, Senkai New Materials quoted 10,270 yuan, Kaishi Group quoted 10,500 yuan, and Tongkun Group quoted 10,560 yuan. The gap between the highest and lowest reached 460 yuan, or roughly 4.6 percent.
What the Price Divergence Really Means
The most noteworthy aspect of this data is not the level of any single price, but the degree of dispersion among the five quotes. For conventional specifications, leading producers usually quote within a narrow band, with spreads typically under one or two hundred yuan. A spread of 460 yuan indicates that raw material procurement timing, inventory levels, and customer structures are diverging materially among these companies.
Tongkun and Rongsheng sit at the higher end, consistent with their integrated supply chain positioning and high proportion of long-term contract customers, which reduces their incentive to chase volume with low prices. Juxing Chemical Fiber posted the lowest quote, possibly reflecting a阶段性 destocking push or a more flexible pricing strategy targeting specific customer groups. Senkai and Kaishi occupy the middle ground, tracking the mainstream market range.
For buyers, this means the room for price comparison on the same specification has widened noticeably. The era of purchasing without shopping around is temporarily over. Active inquiry and multi-source comparison can deliver meaningful cost savings at current price levels.
Industrial Belt Transmission and Supply-Demand Dynamics
Zhejiang is the core production region for polyester filament in China, with Shaoxing and Hangzhou hosting a complete industrial chain from polymerization to texturing. Keqiao in Shaoxing, as a downstream weaving and fabric distribution hub, is highly sensitive to DTY price movements. Hangzhou concentrates leading players such as Tongkun, Rongsheng, and Kaishi, whose quotes are often viewed as market benchmarks.
Behind the price divergence lies a tug-of-war between supply and demand in the polyester filament market. Upstream PTA and MEG price fluctuations have narrowed, providing stable cost support for DTY, pushing competition back to processing fees, inventory turnover, and customer service.
On the demand side, weaving mills are operating at normal utilization rates, but the sustainability of new orders remains uncertain. Some factories are purchasing on a need-only basis rather than building inventory, further capping upside for DTY prices. When leading producers hold prices firm while smaller suppliers offer flexibility, the spread naturally widens.
The impact on the supply chain is twofold. On one hand, lower-priced cargo reduces raw material costs for weavers, helping maintain profit margins. On the other, if low prices come with quality variability or extended delivery times, downstream production management costs may actually rise.
Practical Implications for Procurement and Trade
From an export perspective, domestic DTY price divergence transmits to fabric costs and ultimately to export quotations. While the 460 yuan per ton spread translates to a limited amount per meter of fabric, the cumulative effect is significant for large-volume orders. Exporters relying on a single supplier quote may end up pricing too high or too low.
From a factory perspective, raw material procurement strategies need to become more granular. The price differences among suppliers create room for batch purchasing and off-peak restocking. However, excessively low prices may come with longer payment terms or stricter minimum order quantities, meaning the actual comprehensive cost may not be the lowest.
Industry public data shows that processing fee margins for polyester DTY have been under sustained pressure in recent years, pushing competition into the realm of refined cost management. Price divergence is not a short-term phenomenon but a reflection of the evolving competitive landscape.
