The same specification of polyester POY, sold in two adjacent cities in Zhejiang, can differ by 310 yuan per tonne. Industry quotations on September 11 showed that 150D/48F semi-dull first-grade melt-spun POY was offered at 9,050 yuan/tonne by a Shaoxing mill, while two Hangzhou-based producers quoted 9,150 and 9,360 yuan/tonne respectively. For a product as standardized as POY, that spread is unusual.
Cost Stratification Behind the Spread
POY is one of the most standardized items in the chemical fiber chain. Products of the same specification and grade should theoretically trade within a very narrow band. A 310 yuan/tonne gap, equivalent to 3.4% of the quotation, is wide enough to cover a meaningful portion of processing costs. This implies that at least one of raw material cost, energy cost or financing cost differs materially among the three producers.
Although Shaoxing and Hangzhou both sit in Zhejiang, their chemical fiber supply-chain logic is not identical. Shaoxing leverages the Keqiao fabric cluster, with short procurement radii for PTA and MEG, low logistics costs and dense downstream weaving capacity. POY is absorbed quickly and inventory pressure is relatively manageable. Hangzhou-based producers, by contrast, serve more external markets and contract customers, embedding higher service and credit costs into their pricing.
Notably, the lowest-priced supplier is not the largest. This suggests that in the POY segment, scale effects are being partially offset by raw material integration. Mills with upstream PTA or MEG capacity have a stronger buffer against feedstock price swings, while those relying entirely on purchased raw materials must reflect cost pressure in quotations in real time.
From a chain transmission perspective, POY quotation divergence spreads downstream along two paths. The first is price: weavers will prioritize inquiries toward lower-priced regions, forcing higher-priced mills to adjust quotations or offer payment-term compensation. The second is quality: differences in chip sourcing, spinning processes and oil formulations ultimately show up in texturing breakage rates and dyeing uniformity.
Real Impact on Downstream
For texturing mills, the 310 yuan spread is not a simple procurement choice. If lower-priced POY comes with higher breakage rates, efficiency losses in texturing may exceed raw material savings. Industry experience suggests that differences in POY processability become significantly amplified when texturing speeds exceed 800 meters per minute. Procurement decisions, therefore, cannot rely on quotation sheets alone.
For exporters, POY price divergence transmits through fabric costs into export quotations. Fabrics made from lower-priced Shaoxing POY have greater quotation flexibility, a competitive advantage that cannot be ignored amid volatile external demand and fragmented orders. However, lower-priced feedstock may bring more challenges in batch consistency, and exporters need to budget for quality communication costs when taking long orders.
Over a longer cycle, POY pricing power is shifting from a simple cost-plus model toward a broader contest of regional integration, customer structure and capital efficiency. Shaoxing's lower quotations essentially reflect high turnover and low inventory costs within the industrial cluster; Hangzhou's higher quotations embed greater contract stability and service premiums. Both models are rational, and neither is absolutely superior.
For buyers, the current window is worth revisiting supplier structures. A wider spread means more room for comparison, but also requires more careful assessment of quality stability and delivery reliability. For mills, differences in cost pass-through capability will be further amplified in the next round of feedstock volatility. Locking in raw material integration or adjusting customer mix in advance is more critical than simply chasing quotation competitiveness.
