The polyester staple fiber market experienced a new round of price adjustments in June 2026. According to publicly available data from China's textile industry, the benchmark price of polyester staple fiber closed at 7,419.88 yuan per ton on June 30, down 5.26% from the beginning of the month at 7,831.69 yuan per ton, with a single-day decline of 0.43%. This price level has fallen more than 1,000 yuan from the one-year high of 8,426.02 yuan per ton but still holds an approximately 18% premium over the year's low of 6,267.17 yuan per ton.
Price Trends and Industry Signals Looking at the annual statistical range, the current price of 7,419.88 yuan per ton is near the one-year median of 7,346.6 yuan per ton, neither touching the bottom nor approaching the top. The annual price volatility reached 2,158.85 yuan per ton, reflecting intense supply-demand fluctuations in the polyester staple fiber market. Notably, the current price is about 6.6% above the one-year average of 6,962.04 yuan per ton, indicating that the market remains in a relatively high range, though downward pressure has been largely released.
For the textile supply chain, polyester staple fiber is a core chemical fiber raw material, and its price changes directly affect yarn, fabric, and even garment costs. The sustained decline since June benefits downstream weaving mills by easing cost pressures, but it also raises concerns about weak demand. Industry data shows that although the daily decline is only 0.43%, the month-to-date cumulative drop exceeds 5%, a rare pace in the past six months, reflecting concentrated short-term selling.
Supply-Demand Imbalance Drives the Decline The primary driver of this price decline is the supply-demand imbalance. On the supply side, domestic polyester staple fiber plant operating rates remain high, with new capacity continuing to come online, leading to inventory accumulation. On the demand side, the growth rate of textile and apparel exports has slowed, and domestic consumption recovery has been lackluster, prompting weaving mills to adopt a just-in-time procurement strategy with low restocking willingness. This 'strong supply, weak demand' pattern intensified in June, forcing holders to offer discounts to move inventory.
From a regional perspective, major polyester staple fiber producing areas in Jiangsu and Zhejiang provinces are experiencing significantly increased shipment pressure, with some small and medium-sized factories reporting inventory buildup. In fabric distribution hubs like Shengze and Keqiao, traders remain cautious, waiting for prices to stabilize further. This tug-of-war between upstream and downstream players prevents short-term prices from forming a clear direction.
However, the sustained price decline is also triggering market self-correction mechanisms. The current price of 7,419.88 yuan per ton is approaching the cost line for some producers, limiting further downside. Industry data shows the year's low of 6,267.17 yuan per ton occurred at the end of 2025, when the market underwent a deep destocking cycle. While the current price is still over 1,100 yuan above that low, falling raw material prices for PTA and MEG are weakening cost support.
