Narrow Price Divergence in Polyester DTY: Signals of Capacity Game in Zhejiang's Fiber Belt

On August 4, polyester DTY (150D/48F, AA grade) quotes in Zhejiang's chemical fiber belt ranged from 9,300 to 9,650 CNY/ton, a spread of 350 CNY/ton. This seemingly minor fluctuation is a direct reflection of diverging pricing strategies among regional leaders amid an overcapacity cycle.

The Logic Behind Price Divergence

Quote data shows Shaoxing's Juxing Chemical Fiber offered the lowest at 9,300 CNY/ton, while Tongkun Group quoted the highest at 9,650 CNY/ton, a 3.8% difference. In Hangzhou, Rongsheng Petrochemical and Zhejiang Jisi New Materials both quoted 9,450 CNY/ton, while Zhengkai, Kaisi, and Senkai New Materials aligned at 9,550 CNY/ton. This price clustering within the same region and specification indicates that companies are anchoring prices to secure orders rather than purely following costs.

Notably, the Shaoxing-Hangzhou gap is not coincidental. Shaoxing, as a dense cluster of chemical fiber SMEs, often shows more aggressive price cuts to win orders, while Hangzhou firms, with integrated upstream-downstream advantages, can afford firmer quotes. This regional divergence actually reflects different capacities to buffer market downturns.

Supply-Demand Imbalance and Price Outlook

The 350 CNY/ton spread is not extreme historically, but its signal is significant given current operating rates and inventory levels. Public data shows that new polyester filament capacity was released intensively in H1 2026, while downstream weaving orders grew at a slower pace, widening the supply-demand gap. Low-quote companies are likely destocking rather than cost-driven.

For buyers, this means short-term bargaining room, but they should be wary of quality and service risks behind low prices. For mills, sustained price wars will compress margins and force outdated capacity out. In a shakeout phase, cash flow matters more than profit margins.

Event Impact: Chain Reactions in the Industrial Belt

This quote update is not isolated. It signals a re-pricing process within Zhejiang's fiber belt: high-cost, small-scale capacity may be forced to cut prices to clear inventory, while integrated leaders maintain price premiums. This divergence will transmit upstream and downstream—PTA and MEG pricing negotiations may face pressure, while fabric mills may seize the opportunity to squeeze raw material costs.

Customs data shows that polyester filament exports grew in volume but declined in average price in H1 2026, indicating low-price competition overseas. With weak domestic demand and external sales pressure, polyester DTY prices are likely to remain weak and volatile in H2, with 9,300 CNY/ton as a potential short-term support level.

Practical Recommendations

For Buyers - Monitor the price gap between Shaoxing and Hangzhou; if it widens beyond 400 CNY/ton, consider short-term contracts with lower-priced suppliers to lock in costs. - While negotiating down, request recent quality inspection reports and stable supply commitments to avoid quality compromises. - Leverage the buyer's market to establish multi-supplier price comparison, but avoid excessive pressure that could strain supply relationships.

For Exporters - Build exchange rate buffers into quotes; with two-way volatility, use forward hedging tools. - Consider quarterly pricing agreements with overseas clients to mitigate downside risk from raw material price declines. - Monitor demand changes in Southeast Asia and South Asia; if local capacity expands, export prices may drop further—adjust market strategies early.
