The same POY specification, on the same day, in two adjacent Zhejiang cities, quoted at three different prices — 9,050, 9,150 and 9,360 yuan per tonne. A 310-yuan gap for identical 150D/48F semi-dull first-grade yarn. In the past, such divergence appeared only during violent raw-material swings. Today, with no extreme feedstock move, the spread persists. The pricing logic is shifting from cost-driven to capacity-structure and order-quality driven.
Three Sources of the Spread
China Customs data and industry disclosures show that since early 2026, Zhejiang melt-spinning POY capacity has further concentrated among leading players. Yet smaller plants have not exited; they have pivoted to differentiated filament counts and custom-lustre small-batch orders. The result: actual transaction prices for the same nominal grade are sliced into multiple tiers.
- Shaoxing: Juxing Chemical Fibre quoted 9,050 yuan/tonne, close to downstream texturing clusters, short logistics radius, volume-oriented
- Hangzhou: Rongsheng Petrochemical quoted 9,150 yuan/tonne, clear scale effect, mid-tier price, stability premium
- Hangzhou: Senkai New Materials quoted 9,360 yuan/tonne, smaller scale, higher quote, reflecting a customer base skewed toward small-batch, high-spec orders
These three tiers are not simply "big plants cheaper, small plants dearer." Each corresponds to different delivery schedules and payment terms. Buyers who compare unit prices alone easily overlook hidden costs embedded in credit terms, minimum order quantities and batch consistency.
Industrial Transmission Behind the Gap
From a chain perspective, a widening POY spread hits the texturing segment first, not weaving. Texturers' margins depend on the processing spread between POY procurement and DTY selling prices. When POY itself shows a 310-yuan procurement gap, the cost gap between texturers widens in tandem.
This means the same DTY order can see quotes differing by 200-400 yuan/tonne across texturers, while downstream weavers comparing DTY quotes rarely trace the source of the difference. For buyers, understanding POY-tiering is equivalent to holding advance bargaining chips for DTY negotiations.
Another overlooked variable is regional inventory. Shaoxing hosts dense texturing capacity, so POY is absorbed locally at a faster pace, with inventory turnover days typically lower than in Hangzhou. Some Hangzhou producers ship POY to Shaoxing and Xiaoshan, and transport plus warehousing costs are baked into quotes. This is one objective reason why both Hangzhou quotes sit above Shaoxing.
Practical Impact on Procurement and Export
The current 310-yuan/tonne spread, on the mainstream 150D/48F spec, equals roughly a 3.4% price band. For a texturer or weaver purchasing over 500 tonnes monthly, that translates to a cost difference exceeding 150,000 yuan per month — enough to affect cash-flow planning at a mid-sized plant.
The export impact is more indirect but equally real. Polyester fabric export orders using POY as feedstock are typically quoted on a cost-plus basis. If a buyer locks in high-priced supply while a competitor secures low-priced supply, the competitiveness gap in export quotes will show up directly in order wins, quality being equal.
Notably, a lower price does not always mean a better source. Some low quotes come with stricter payment terms or longer lead times. For lead-time-sensitive export orders, a higher but stable source may actually reduce overall risk.
Actionable Takeaways
For Buyers - Build a cross-regional comparison mechanism, tracking both Shaoxing and Hangzhou POY quotes rather than relying on a single supplier - Factor credit terms, minimum order quantities and batch consistency into total cost, not just unit price - For specs exceeding 300 tonnes monthly, consider batched lock-ins to reduce single-purchase price risk - Monitor texturing cost transmission and use POY spread information to validate DTY quote reasonableness
For Exporters - Specify feedstock lock-in methods within quote validity periods to prevent POY spread volatility from eroding margins - For lead-time-sensitive orders, prioritise mid-priced but reliably delivered sources over chasing the absolute lowest price - Incorporate feedstock spreads into export quote sensitivity analysis and pre-set acceptable price fluctuation ranges
Looking ahead, POY quote tiering will not converge in the short term. Structural divergence in melt-spinning capacity, regional concentration of texturing clusters and the small-batch trend in downstream orders are all reinforcing this pattern. What buyers must adapt to is not a one-off spread, but a persistently multi-tiered quoting market.
