Polyester Staple Fiber Price Retreats to Mid-Range, Market Intensifies

The benchmark price of polyester staple fiber closed at 7,419.88 RMB/ton on June 30, 2026, marking a 5.26% decline from the beginning of the month. This drop is not an isolated event but a reflection of the price oscillating within the mid-range after falling from a one-year high of 8,426.02 RMB/ton. Industry data shows the current price still holds a 1,152.71 RMB premium over the yearly low of 6,267.17 RMB/ton, yet it has lost over 1,000 RMB from the peak. This indicates that upstream inventory pressures are transmitting downstream, while weaving mills remain hesitant to restock.

Supply-Demand Dynamics Behind the Price Move

Over the past 12 months, polyester staple fiber prices have swung widely between 6,267 and 8,426 RMB/ton, with an average of 6,962 RMB/ton. The current level of 7,419 RMB sits slightly above the mid-point of 7,346 RMB, but the daily decline of 0.43% suggests a lack of directional momentum. On the cost side, raw materials like PTA and MEG have remained relatively firm, providing a floor for polyester staple fiber. However, the recovery in downstream orders for apparel and home textiles has been slower than expected, limiting mill operating rates and keeping restocking to a hand-to-mouth basis. This tug-of-war between cost support and weak demand keeps the price stuck in the middle range.

Ripple Effects in Industrial Clusters

Feedback from textile clusters like Keqiao and Shengze aligns closely with the price data. In Shengze, where polyester staple fiber is a key raw material for blended yarns, price fluctuations directly impact grey fabric cost calculations. Industry surveys show that local weaving mills now maintain only 7-10 days of raw material inventory, down from 15-20 days last year. This 'buy-as-needed' approach is a direct hedge against the downward price trend. In the Nantong home textile market, demand for polyester staple fiber filling has also entered a seasonal lull; summer is traditionally a slow season, and with falling price expectations, buyers are postponing large orders.

Strategies for the Mid-Range Game

Historically, when polyester staple fiber prices trade between 7,267 and 8,426 RMB/ton, market buying and selling are most intense. At the current 7,419 RMB level, it is neither a safe bottom nor a profitable peak. For mills, fixed costs remain unchanged; every 100 RMB drop in raw material prices expands finished product margins, but only if orders are stable. For exporters, the uncertainty of RMB exchange rates and overseas end-demand complicates decisions on hedging and forward contracts.

Practical Recommendations

For Buyers - The current price is in the lower-mid range; consider phased purchasing to avoid heavy positions during a downturn. Use weekly averages as a reference and increase volumes when prices dip below 7,300 RMB/ton. - Monitor PTA and MEG inventory levels: if upstream destocking accelerates, the floor for polyester staple fiber will strengthen, making quarterly contracts a viable option for cost locking.

For Exporters - For inquiries from Southeast Asian and South Asian clients, propose floating pricing clauses that index settlement to the polyester staple fiber price to hedge raw material volatility. - Use the current mid-range window to negotiate processing fees with dyeing and garment factories in advance, protecting order margins if prices rebound later.
