When the quotation spread for the same specification of polyester DTY across five major Zhejiang mills compresses to less than 5%, the market is no longer engaged in simple price competition — it is redistributing pricing power over processing margins. On September 11, 2026, 150D/48F semi-dull low-elasticity polyester DTY was quoted between 10,100 and 10,560 yuan/ton across leading Zhejiang producers, a maximum gap of just 460 yuan/ton. That number itself deserves more attention than any single quote.
Quotation Structure: Who Anchors, Who Follows
Public data shows no clear stratification between the Shaoxing and Hangzhou industrial belts. Juxing Chemical Fiber sits at the lower bound of 10,100 yuan/ton, while Tongkun Group quotes 10,560 yuan/ton at the upper end. Rongsheng Petrochemical, Kaishi Group, and Senkai New Materials fall between 10,270 and 10,550 yuan/ton. A spread of under 500 yuan/ton among leading players indicates that cost curves under the melt-spinning route have become highly convergent.
For buyers, the immediate consequence is a narrowing window for price comparison. The bargaining advantage once gained through cross-mill inquiries is eroding, and the marginal benefit of switching suppliers is declining. Conversely, this suggests that leading enterprises are forming a tacit understanding around processing fee floors — no one wants to be the first to break the price equilibrium, because the cost of restarting production after falling below cash cost far exceeds short-term concessions.
Notably, all quotes in this round point to the 150D/48F standard specification. This is the most liquid DTY grade and the best indicator of genuine industry supply and demand. When standard product quotes are highly concentrated, it typically means inventory levels are neutral — neither panic selling nor supply shortage expectations are present.
Industry Impact: Processing Margin Competition and Capacity Discipline
The pricing logic of polyester DTY is essentially PTA and MEG costs plus a processing fee. When raw material volatility moderates, the processing fee becomes the core variable determining profitability. With five Zhejiang mills quoting between 10,100 and 10,560 yuan/ton, the processing fee space is compressed into a relatively narrow range, placing sustained pressure on highly leveraged, high-depreciation older capacity.
From a capacity perspective, integrated players like Tongkun and Rongsheng benefit from PTA self-sufficiency and economies of scale. Their upper-bound quotes reflect brand premium and delivery reliability rather than cost disadvantage. In contrast, mills at the lower bound often rely on flexible scheduling and regional customer stickiness to maintain shipments. This divergence means future DTY competition will shift from pure price wars to a comprehensive contest of delivery cycles, batch consistency, and payment terms.
For downstream weaving and texturing enterprises, stable raw material prices send a dual signal. On one hand, clear cost expectations facilitate order quotations. On the other, if end-use fabric orders do not recover in tandem, the pressure of compressed processing fees will transmit upward through the supply chain. Texturing plants around Shaoxing and Hangzhou need to assess whether current price levels have already touched the cash flow breakeven line for some factories.
Practical Recommendations
For Buyers - In a convergent pricing environment, prioritize batch color consistency and on-time delivery rates over chasing the lowest price - Explore spread opportunities in specifications beyond 150D/48F, where bargaining room is typically wider - For medium-to-long-term volumes, consider lock-in agreements but include adjustment mechanisms linked to raw material indices
For Exporters - Shorten quotation validity to 7–10 days to avoid raw material volatility eroding margins - Specify semi-dull versus full-dull and low-elasticity versus high-elasticity in contracts to reduce delivery disputes - Monitor Southeast Asian buyers' alternative sourcing moves — Zhejiang DTY's export competitiveness is shifting from price to quality consistency
Overall, the 460 yuan/ton spread is both an outcome and a signal. It shows that pricing discipline in Zhejiang's polyester industrial belt is strengthening, but it also reminds market participants that as price competition space narrows, the real battle returns to product consistency and supply chain efficiency.
