A 310 Yuan/Tonne Spread in Polyester POY Quotes: What Signal Is the Shaoxing-Hangzhou Belt Sending?

A 310 yuan per tonne spread for the same polyester POY specification, in two neighbouring Zhejiang cities on the same day, is not a market failure. It is a direct readout of diverging cost structures and inventory positions inside the industrial belt. On 11 September 2026, 150D/48F semi-dull first-grade melt-spun POY was quoted at 9,050 yuan per tonne in Shaoxing, while two Hangzhou producers quoted 9,150 and 9,360 yuan per tonne. For downstream weavers, that gap already exceeds the processing margin on most standard orders, which means procurement decisions can no longer rely on a vague "Zhejiang average".

The logic behind the spread

Shaoxing and Hangzhou sit in the same core chemical fibre zone, but their capacity structures differ. Shaoxing hosts a dense cluster of small and mid-sized fibre makers tied to texturing and weaving, where POY is largely consumed locally, logistics radii are short and inventory turns fast, pushing quotes closer to cash cost. The two Hangzhou sellers are different animals: one is a leading integrated refining and petrochemical group whose costs track the crude-PX-PTA chain, while the other is a new materials player that may command a premium through differentiated scheduling.

The 310 yuan per tonne range means a buyer sourcing at the low end saves roughly 3.4% versus the high end. For a mid-sized texturer consuming 500 tonnes a month, that is more than 150,000 yuan of additional gross margin per month. Conversely, higher-priced sellers that cannot compensate through quality consistency, delivery reliability or payment terms will see orders erode quickly.

Upstream and downstream transmission

On the cost side, PTA and MEG, the direct feedstocks for melt-spun POY, have not shown a one-way collapse recently. The current spread therefore stems more from supply-demand rhythm than from a feedstock shock. Firm quotes from the integrated major suggest a high share of contract customers and limited spot exposure, while lower quotes from smaller players reflect a willingness to trade price for volume when order books are thin.

For texturers, POY purchase cost sets the floor for DTY quotes. If cheap supply persists, DTY market prices will be dragged lower, compressing texturing conversion fees. For weavers, the divergence at the raw material end actually opens a window: by switching suppliers prudently, while safeguarding batch shade consistency and yarn evenness, they can improve cost structure without sacrificing finished quality.

It is also worth noting that such a spread for a single specification often signals a stratification of regional inventory. If low-priced Shaoxing supply keeps flowing, it could pull more surrounding weaving capacity towards Shaoxing, while higher-priced Hangzhou producers will need product upgrades or service lock-in to retain customers.

Practical takeaways

For buyers - Do not rely on a regional average; compare supplier by supplier and assess whether the 310 yuan per tonne gap covers trial-run and shade-variation risks. - For high-volume specifications, consider short-term price-lock agreements with low-cost suppliers while keeping a higher-priced vendor as a quality backup. - Request batch-level data on shade variation, oil content and yarn evenness CV to verify whether low prices are sustainable.

For mills - Higher-priced producers should shift competition from price to delivery stability, payment terms and technical service, or risk continued order erosion. - Lower-priced producers must watch cash flow drain from volume-for-price tactics and avoid being forced to restock when feedstock rebounds. - Texturing and weaving operations should build a weekly raw material price comparison mechanism and feed spreads of this magnitude into procurement models, rather than relying on monthly averages.
