The same specification of polyester DTY can differ by more than 600 RMB per ton within a single trading day. That is not random bargaining by traders — it is the real spread quoted by several major producers in Zhejiang. Identical parameters — 150D/48F, semi-dull, low-elasticity, AA grade — carried factory prices ranging from 10,250 to 10,910 RMB per ton, with no discount or payment-term differences involved.
What the Spread Reveals
Tongkun Group quoted 10,910 RMB per ton at the top of the range. Rongsheng Petrochemical stood at 10,700 and Kaishi Group at 10,650 in the middle. Senkai New Materials quoted 10,420, while Zhejiang Yongsheng anchored the bottom at 10,250. All are based in Zhejiang, with Hangzhou and Shaoxing accounting for nearly the entire sample.
The gap is not accidental. Higher quotes from leading players typically correspond to more consistent batch quality, a fuller inspection chain and stronger service capacity for long-term contract clients. Lower quotes tend to come from suppliers that are more flexible on spot turnover, regional delivery or small-to-mid-sized orders. For buyers, the 600-plus RMB difference is essentially a choice between buying certainty and buying flexibility.
It is also worth noting that Yongsheng listed the identical 10,250 RMB per ton price twice on the same day. Repeated listings usually signal that the level is a tradeable anchor rather than a tentative offer.
Why This Spread Matters
Polyester DTY prices are never isolated numbers. On the cost side they connect to PTA and MEG; on the demand side they link to texturing, weaving and end-use apparel orders. When products of the same specification show clear stratification within a single region, it means the market is no longer in a homogeneous phase where everything rises or falls together.
For upstream mills, a widening spread raises the risk of customer attrition. Producers quoting above the midpoint must compensate through delivery times, batch consistency or payment terms, or small and mid-sized weavers will quickly migrate to cheaper suppliers. Conversely, low-priced players are not guaranteed winners — sustained low pricing squeezes processing margins, and when raw material costs swing, they are the first to feel the strain.
For downstream weaving and export operations, the immediate impact is greater difficulty in cost accounting. Quoting off a market average has become misleading now that the spread exceeds 600 RMB. On a 300-ton order, choosing the wrong supplier could add nearly 200,000 RMB in raw material costs.
Regional Signals
The sample's concentration in Hangzhou and Shaoxing is no coincidence. Hangzhou hosts players with integrated refining backgrounds or large-scale texturing capacity, such as Rongsheng and Kaishi. Shaoxing, anchored by the Keqiao fabric belt, has formed a short-chain ecosystem from raw material to weaving. The price difference between the two cities reflects, to some degree, the cost structures of a raw-material-self-sufficient model versus a market-support model.
Industry data shows Zhejiang has long been China's core production region for polyester filament and DTY, with high capacity concentration and fast price signal transmission. When stratification emerges within this region, it typically spreads to texturing plants in Jiangsu and Fujian within one to two weeks, shifting the national DTY trading center of gravity.
Another variable that cannot be ignored is the specification itself. 150D/48F semi-dull low-elasticity yarn is a standard item in weaving — high volume, highly substitutable. That is precisely why its spread is so indicative. If even a standard specification shows stratification, it suggests the market is shifting from seller pricing to buyer selectivity.
