A price gap of merely 400 yuan between 8,500 and 8,750 yuan/ton reveals the divergence and anxiety within Zhejiang's polyester FDY industrial cluster. On June 26, 2026, public quotes from six major producers—including Rongsheng Petrochemical, Tongkun Group, and Tiansheng Chemical Fiber—showed that the price of standard polyester FDY (150D/96F, AA grade, semi-dull) has slipped from around 9,000 yuan/ton at the beginning of the month, with the lowest quote hitting 8,500 yuan/ton.
Price divergence is no accident. Tongkun Group quoted the highest at 8,750 yuan/ton, while Rongsheng Petrochemical and Juxing Chemical Fiber offered the lowest at 8,500 yuan/ton, a spread of 250 yuan/ton. This typically indicates varying inventory pressures among leading firms or differing expectations for the near-term market. In the chemical fiber industry, pricing is not merely a cost-plus exercise; it is a forward-looking reflection of supply-demand expectations for the coming month.
Micro-Signals of Supply-Demand Imbalance
Geographically, the quoting firms are concentrated in Hangzhou and Shaoxing, the most capacity-dense regions for polyester filament yarn in China. Tiansheng Chemical Fiber quoted 8,710 yuan/ton, Jiabao Fiber 8,510 yuan/ton, and Kaishi Group 8,650 yuan/ton. The clear price gradient suggests significant differences in operational strategies, customer structures, and inventory levels among firms within the same industrial cluster.
The deeper issue lies on the demand side. The primary downstream sectors for polyester FDY are water-jet looms and warp knitting machines, concentrated in Wujiang, Changxing, and Xiuzhou. Since Q2 2026, sluggish growth in end-apparel orders has pulled down weaving mill operating rates from 75% in April to around 68% by mid-June. Inventory pressure transmitting from weaving mills upstream to chemical fiber plants is the direct cause of current price weakness.
Cost Support and Price Bargaining
The direct raw materials for polyester FDY are PTA and MEG. In June, spot PTA prices hovered around 5,800 yuan/ton, and MEG around 4,000 yuan/ton, with no sharp cost-side fluctuations. This implies the recent price decline is driven more by weak demand than by a collapse in costs.
For buyers, the current price range presents an opportunity. The 8,500 yuan/ton level is close to the cash cost line for some small and medium enterprises, limiting further downside. However, for well-capitalized buyers with flexible inventory management, waiting for lower prices carries risk—should downstream orders see a seasonal rebound in July, prices could recover quickly.
Divergent Responses within the Industrial Cluster
Facing downward prices, firms of different sizes are adopting divergent strategies. Integrated players like Rongsheng and Tongkun, with their full PX-PTA-polyester filament value chains, can hedge raw material costs internally. In contrast, specialized firms like Juxing and Jiabao, focused solely on filament production, face greater operational pressure and must cut prices to maintain cash flow.
This divergence will accelerate industry consolidation in the coming months. Cost-advantaged and customer-loyal leading firms may use price wars to further squeeze smaller players. For foreign trade enterprises, current RMB exchange rate volatility and uncertainty in overseas orders complicate procurement decisions.
