From 8,500 to 8,750 yuan per ton—that’s the quote range for polyester FDY 150D/96F semi-dull AA grade on June 26, 2026. The less than 3% price spread masks a subtle shift in the supply-demand landscape within China’s chemical fiber industrial belt: leading producers are adopting divergent pricing strategies, while downstream weaving mills are growing increasingly cautious.
Price Divergence Reveals Capacity Game
Public quote data collected on June 26 shows a tiered distribution among major polyester FDY suppliers in Zhejiang Province: Rongsheng Petrochemical and Zhejiang Juxing Chemical Fiber at the low end of 8,500 yuan/ton, Zhejiang Jiabao New Fiber at 8,510 yuan/ton, Hangzhou Kaishi Chemical Fiber at 8,650 yuan/ton, Zhejiang Tiansheng Chemical Fiber at 8,710 yuan/ton, and Tongkun Group at the high end of 8,750 yuan/ton. This range spans the chemical fiber belt from Xiaoshan to Shaoxing, reflecting differentiated pricing strategies based on inventory levels, operating rates, and customer structures.
Notably, the 250 yuan/ton gap between the lowest and highest quotes is unusual for a normally quiet season. Typically, price spreads for similar products narrow to 50-100 yuan/ton when supply and demand are balanced. The current divergence suggests some firms face inventory pressure and are using price cuts to move volume, while others, with stable orders or lower capacity utilization, hold firm on higher prices.
The Squeeze Between Costs and Demand
Polyester FDX’s direct feedstocks are PTA and MEG, whose price trends directly impact the cost floor of polyester products. Recent volatility in international crude oil prices has squeezed margins in the PX link, which in turn transmits to the PTA spot market. But the more critical factor is downstream demand: weaving mill operating rates have seen a seasonal decline in late June, especially in major textile clusters like Zhejiang and Jiangsu, where some small and medium-sized mills have begun to cut production or halt operations due to insufficient orders.
Against this backdrop, the 150D/96F specification—being a standard grade—shows high demand elasticity. When upstream feedstock costs rise, downstream buyers tend to reduce raw material inventories, adopting a just-in-time purchasing approach. When feedstock costs fall, wait-and-see sentiment intensifies, creating a negative feedback loop as buyers hold out for even lower prices. The current narrow quote fluctuation is a direct manifestation of this squeeze: mills dare not raise prices aggressively (for fear of losing orders) nor cut them excessively (to protect margins).
Leading Firms’ Pricing Power and Industrial Belt Response
Looking at the quote details, Rongsheng Petrochemical’s 8,500 yuan/ton offer acts as a clear anchor. This price is 250 yuan/ton below Tongkun Group’s and 210 yuan/ton below Zhejiang Tiansheng’s. The leader’s proactive low pricing may aim to capture market share and force out smaller capacity. Tongkun’s insistence on 8,750 yuan/ton likely reflects its differentiated product mix or stability from long-term contract customers.
The chemical fiber belt in Shaoxing and Hangzhou has responded sensitively. Zhejiang Juxing Chemical Fiber and Zhejiang Jiabao New Fiber closely follow Rongsheng’s low end, showing smaller players’ passive posture in the price war. Hangzhou Kaishi’s 8,650 yuan/ton sits in the middle, seeking a balance between market share and profit. This tiered pricing effectively gives downstream buyers clear room for negotiation—for bulk orders, they can use 8,500 yuan/ton as a baseline.
