On August 14, quotes for polyester FDY 150D/96F semi-dull AA grade from three Zhejiang chemical fiber mills showed clear stratification: Rongsheng Petrochemical at 8650 RMB/ton, Tiansheng Chemical Fiber at 8560, and Kaishi Group at 8950. The 390 RMB gap between the highest and lowest quotes far exceeds what can be explained by normal transportation or quality variations. This divergence is not accidental but a direct reflection of current supply-demand dynamics and diverging corporate strategies in the polyester filament market.
The Industrial Logic Behind Price Stratification
For the same specification and grade, a nearly 4% price gap within Zhejiang, the core polyester production region, indicates a shift from a single market price to a 'one mill, one price' reality. Kaishi's high quote of 8950 RMB likely reflects its direct sales model and higher-end customer base; Tiansheng's low 8560 quote may signal active inventory destocking and a focus on cash flow; Rongsheng's mid-range price reflects its pricing power as a large integrated refining-petrochemical enterprise.
For buyers, the widening gap offers both opportunities and risks. A low price may mean the supplier is under inventory pressure and may offer further discounts, but it could also come with compromises in batch consistency or service response. A high price is not necessarily 'inflated'—it may include more stable quality control or shorter lead times. Simply choosing the lowest quote may lead to supply priority issues when the peak season arrives.
Upstream-Downstream Transmission and Regional Response
Polyester FDY is a core raw material for weaving, and its price fluctuations directly transmit to fabric costs and end-order quotes. Under the current price gap pattern, downstream weaving mills tend to adopt batch purchasing and small-lot, quick-response strategies to avoid risks from single-supplier price volatility. Weaving clusters in Shaoxing and Xiaoshan have already adjusted procurement rhythms, with some factories splitting monthly orders into weekly ones to capture quote dips.
Meanwhile, none of the three mills' quotes exceeded the 9000 RMB threshold, indicating the overall market remains in a weak balance. Crude oil prices are fluctuating narrowly, PTA supply is ample, and the cost side lacks strong support. On the demand side, autumn/winter fabric orders have not yet fully started, and terminal apparel brands remain cautious. This 'ceiling above, floor below' pattern is expected to persist until the traditional peak season in September.
Key Points to Watch in the Coming Week
In the short term, three things deserve attention: first, whether Rongsheng, as an industry bellwether, adjusts its quotes, which will influence market expectations; second, whether Tiansheng's low-price strategy can boost shipment volumes—if inventory is quickly digested, the gap may narrow; third, whether Kaishi's high price can hold—if customers defect, it may be forced to follow with price cuts.
Practical Recommendations
For Buyers - Establish a multi-supplier comparison mechanism, focusing on quality and delivery term differences when the price gap exceeds 300 RMB/ton. - Split monthly procurement plans into 2-3 orders to leverage price fluctuation windows and reduce overall costs. - For high-priced suppliers, request batch test reports or trial samples to verify whether the quality premium is justified.
For Foreign Trade Enterprises - Incorporate FDY raw material price fluctuations into risk clauses in export quotes to avoid margin erosion from rising material costs after locking in prices. - Monitor Zhejiang mills' quote dynamics as reference for negotiations with overseas clients, strengthening bargaining arguments. - If clients designate low-priced suppliers, confirm their production capacity in advance to prevent supply disruptions during peak season.
In summary, the 390 RMB gap is not market failure but a sign of industrial maturity. Both purchasing and sales decisions should shift from a 'price-only' mindset to a 'comprehensive value' approach, seeking certainty amid volatility.
