On September 1, 2026, the benchmark price of polyester staple fiber settled at 7816.55 CNY per ton, up 0.93% from the previous day and 3.32% from the start of the previous month. While the number itself may not seem dramatic, it has climbed to a mid-to-high position within the annual range—more than 24% above the year's low of 6267.17 CNY per ton. This upward shift in raw material prices is now transmitting through the yarn, fabric, and garment segments, potentially reshaping profit distribution across the textile supply chain at a critical moment this year.
The Logic Behind the Price Center Shift
Annual statistics show that over the past 12 months, polyester staple fiber averaged 7126.48 CNY per ton, with a median of 7346.6 CNY. The current price is nearly 10% above that average, indicating a trend rather than a temporary spike. The distance to the year's high of 8426.02 CNY is only about 7.8%, leaving room for further upside.
For buyers, this means raw material costs are rising structurally, and the benefits of earlier low-price stockpiling are fading. For mills, the key question is whether higher input costs can be passed down to downstream customers, which depends on final order demand. Historically, when polyester staple fiber prices break above the median, weaving mills tend to increase restocking, but if end demand fails to support, a standoff between high prices and low volume may emerge.
Transmission and Regional Industrial Cluster Reactions
Polyester staple fiber is a primary raw material for cotton and blended yarns, directly affecting procurement costs in clusters like Shengze and Keqiao. In Shengze, where chemical fiber weaving is dense, raw materials often account for over 70% of costs, so this price hike will squeeze margins. Keqiao's home textile producers, including curtain and sofa fabric makers, face similar pressures.
On the flip side, rising prices signal demand. If downstream orders are robust, companies can raise product prices to pass through costs; otherwise, they may have to absorb the hit. Public industry data indicates loom utilization in Jiangsu and Zhejiang remains around 70%, suggesting demand has not weakened significantly, providing some support for price transmission.
Price Expectations and Inventory Strategy
With the price at a mid-to-high annual position and a daily gain of 0.93%, short-term momentum remains strong. For exporters, currency fluctuations combined with rising raw material costs are narrowing the window for adjusting export quotations. Monitoring the basis between futures and spot prices is advisable; if the basis strengthens, locking in forward order prices could mitigate risks.
From an inventory cycle perspective, rising raw material prices often trigger a 'buy on rising' psychology, potentially stimulating a restocking wave. But caution is warranted: if final consumption recovery disappoints, high-cost inventory could become a burden. Therefore, companies should avoid chasing highs and adopt phased procurement to smooth cost volatility.
Practical Recommendations
For Buyers - Purchase on demand, avoid bulk hoarding, and split orders into 3-4 batches to hedge against price corrections. - Monitor the spread between polyester staple fiber and cotton; if it widens, adjust blending ratios to optimize cost structures.
For Exporters - Include raw material price adjustment clauses in contracts or use forward pricing to hedge dual risks from materials and exchange rates. - Strengthen quarterly negotiations with suppliers for more flexible payment terms to ease cash flow pressure.
The upward shift in polyester staple fiber prices is both a cost challenge and a signal of industry health. In times of unclear demand and manageable inventories, rational response beats chasing trends. The resilience of the textile chain lies in such fine-tuned management amid price volatility.
