Polyester Staple Fiber Price Center Shifts Up: Narrowing Annual Range Signals New Market Equilibrium

The price center of polyester staple fiber (PSF) is undergoing a structural upward shift. As of July 28, 2026, the industry benchmark stood at 7532.75 CNY/ton, up 1.54% from 7418.65 CNY/ton at the beginning of the month. However, a day-on-day decline of 1.70% suggests short-term correction pressure. This level sits slightly below the median of the annual range, nearly 900 CNY/ton below the year's high of 8426.02 CNY/ton, but more than 1200 CNY/ton above the low of 6267.17 CNY/ton.

Narrowing Price Range: A New Phase in Supply-Demand Dynamics

Over the past year, PSF prices fluctuated between 6267.17 and 8426.02 CNY/ton, with an amplitude of approximately 34.4%, down from over 50% in the previous year. The narrowing range indicates that market participants' expectations have converged, improving price discovery efficiency. The annual average of 7019.32 CNY/ton suggests the current price is about 7.3% higher, meaning the price center has moved up. For weaving mills, this implies a higher bottom for raw material costs, reducing the cost-effectiveness of low-inventory strategies.

Behind the Daily Decline: Short-Term Supply and Inventory Dynamics

The 1.70% daily drop is not a trend reversal signal but likely a normal correction following increased supply. July typically sees a mix of maintenance shutdowns and restarts in PSF plants. The resumption of some previously idled capacity has temporarily boosted supply. Meanwhile, downstream weaving mills have slowed procurement after early-month restocking, leading to a price pullback. From an annual perspective, current prices remain in a healthy range, far from any warning level, indicating stable industry operations.

Transmission to Downstream Weaving and Apparel Chains

PSF is a key raw material for cotton substitute blends and fillers. Its price changes directly affect fabric costs and end-product pricing. The upward shift in the price center means fabric mills must recalculate cost structures. For export orders involving polyester-cotton blends, if the RMB exchange rate fluctuates simultaneously, profit margins will be squeezed from both sides. On the positive side, a narrower price range facilitates long-term contract pricing negotiations, reducing default risks caused by sharp raw material swings.

Regional Industrial Cluster Reactions: Procurement Strategy Adjustments from Keqiao to Shengze

In the Keqiao and Shengze textile clusters, PSF price changes have already been reflected in grey fabric quotes. According to publicly available industry data, since mid-July, quotes for some standard polyester-cotton grey fabrics have risen by about 2%-3%, but end-brand acceptance remains limited. Buyers generally adopt a "procure on demand, small orders with quick turnaround" model to avoid inventory depreciation from price fluctuations. Some mills in Shengze have started adjusting product mixes, increasing the use of differentiated PSF products to mitigate price risks in homogeneous competition.

Practical Recommendations

For Buyers - With prices in the lower-middle part of the annual range, consider moderately increasing safety stocks to lock in raw material costs for the next 2-3 months. - Monitor plant maintenance schedules: some PSF factories have annual maintenance plans in August-September, which could tighten supply and push prices up. Advance stockpiling can hedge against sudden spikes. - When negotiating floating-price agreements with suppliers, use the annual average of 7019 CNY/ton as a baseline and set price adjustment triggers at ±5%.

For Export Enterprises - When quoting export orders, include a raw material price fluctuation clause, basing cost calculations on a PSF price range of 7000-8000 CNY/ton. - Monitor the correlation between RMB exchange rate and PSF prices: if both rise simultaneously, export margins will shrink significantly. Communicate price adjustment mechanisms with clients in advance. - Use forward exchange contracts to lock in exchange rates while signing short-term supply agreements with upstream suppliers to reduce uncertainty from dual fluctuations.
