The same specification of polyester DTY, within the same province and the same week, can show a price gap of nearly 700 yuan per ton. That number itself is a signal. In late September 2026, mainstream quotations for 150D/48F semi-dull low-elasticity AA-grade white yarn in the Zhejiang market ranged from 10,250 to 10,910 yuan per ton. Six suppliers did not converge; instead, they formed clear tiers. For downstream weaving mills, this is not an ordinary quotation sheet but a health check on cost expectations and inventory pressure.
Three Layers of Divergence in the Quotation Structure
Start with the prices themselves. At the top of the range, Tongkun Group quoted 10,910 yuan per ton. Rongsheng Petrochemical and Kaishi Group quoted 10,700 and 10,650 yuan respectively, forming the middle tier. Senkai New Materials quoted 10,420 yuan, while Zhejiang Yongsheng in Shaoxing offered 10,250 yuan, the lowest in the range. The spread between the highest and lowest is 660 yuan, or about 6.4%.
Why does this spread matter? Because 150D/48F is a highly standardized DTY variant—melt-spun, semi-dull, low-elasticity, AA-grade—with nearly identical parameters. Theoretically, products of the same specification should not show such wide dispersion. The existence of this gap indicates that suppliers are at very different positions in terms of raw material procurement rhythm, chip inventory costs, and order saturation.
Now look at geography. Quoting entities are concentrated in Hangzhou and Shaoxing. Hangzhou-based firms—Rongsheng, Kaishi, and Senkai—generally quote higher, while Shaoxing's Yongsheng is notably lower. Hangzhou and Shaoxing both belong to the Hangzhou Bay chemical fiber belt. Logistics radius differences cannot explain a gap of hundreds of yuan; more likely, it stems from different long-term contract raw material costs and recent production-sales ratios.
How the Spread Transmits Downstream
For buyers, what does a 660 yuan per ton spread mean? Take a medium-sized weaving mill consuming 300 tons of DTY per month. Choosing the lowest-priced supplier versus the highest creates a monthly raw material cost difference of nearly 200,000 yuan. That magnitude is enough to change a factory's gross margin structure, especially when bargaining room on the fabric side is limited.
But low price does not equal optimal choice. The core variables in DTY procurement have never been just unit price; they include batch consistency, breakage rates, and delivery cycles. Suppliers quoting lower prices are often trading price for order saturation, which may signal elevated inventory or tight cash flow. If buyers fixate only on the lowest price, they may pay hidden costs in subsequent batch consistency.
From a production scheduling perspective, a widening spread usually signals two possibilities: either upstream PTA and MEG costs are loosening, prompting some firms to concede margin early; or downstream texturing and weaving utilization rates are diverging, leaving suppliers with uneven order flows. Either way, DTY prices are likely to reconverge or diverge further within the next two to four weeks.
For export-oriented firms, this dispersion directly compresses the quotation window. Fabric export quotes typically require locking raw material costs for 7 to 15 days. The wider the spread, the higher the locking risk. Using a high-priced supplier's cost may mean losing price competitiveness in bidding; using a low-priced one means bearing the risk of subsequent price hikes.
What to Watch Next in the Supply Chain
Put this quotation sheet back into the broader industrial context. The Zhejiang chemical fiber belt is at a delicate equilibrium. On one hand, polyester filament capacity is highly concentrated, giving leading firms strong price guidance. On the other, smaller suppliers' flexible quotes in niche specifications are becoming an important supplement to market price discovery.
The first indicator to track is the production-sales ratio. If leading firms maintain high quotes while keeping the ratio above 80%, demand still has support, and the spread is structural rather than trend-driven. Conversely, if high quotes coincide with weakening sales, the probability of a downward shift in the price center rises.
The second indicator is texturing utilization. DTY's downstream is texturing and weaving. Once texturing mills' operating rates decline, DTY procurement shifts from刚性需求 to order-based buying. The spread between suppliers would then widen further, because orders themselves become scarce resources.
The third observation point is the price linkage between chips and virgin materials. When chip price volatility increases, integrated producers with in-house facilities enjoy clearer cost advantages and more pricing confidence. Suppliers reliant on purchased chips are more likely to be passive in price competition.
