Polyester staple fiber (PSF) prices are undergoing a moderate but directional correction. As of July 1, 2026, industry data shows the benchmark price at 7,418.65 yuan per ton, down 5.27% from the previous month, with a daily decline of only 0.02%. Over the past 12 months, prices have fluctuated between 6,267 and 8,426 yuan per ton, placing the current level at the mid-range, approximately 12% below the annual peak. This price movement is not an isolated event but a result of weakening upstream raw material costs and subdued downstream demand.
Industrial Signals from Mid-Range Pricing
The current price of 7,418.65 yuan per ton sits near the one-year median of 7,346.6 yuan per ton. This indicates that PSF has neither returned to the low levels of the same period last year nor maintained the high volatility of the first half of the year. With an annual average of 6,963.91 yuan per ton, the current price is slightly above the mean but has clearly departed from the previous high-range channel. For spinning mills, this means raw material costs have dropped by approximately 390 yuan per ton compared to last month, directly reducing the production cost of cotton-type yarns. However, the mid-range pricing also suggests a lack of clear market direction, making it difficult for enterprises to establish long-term price expectations.
Tightening Upstream-Downstream Transmission
The core driver of PSF price correction is the cost collapse in upstream PX and PTA segments. Over the past month, volatility in international crude oil prices has narrowed naphtha cracking margins, pulling down the PX price center. PTA, as the direct feedstock for PSF, has weakened in tandem, compressing processing margins for staple fiber plants. From a transmission timeline perspective, PSF price adjustments typically lag PTA by one to two weeks, and the current magnitude of change aligns with upstream declines, indicating a normal transmission chain.
Notably, downstream demand has not responded positively. Operating rates at spinning and weaving mills saw a slight decline in late June, with some small and medium-sized factories opting for production cuts or maintenance shutdowns to cope with rising finished goods inventories. PSF procurement has thus slowed, with market transactions focused on essential replenishment and speculative hoarding nearly absent. This supply-demand weakness leaves PSF prices with little near-term support for a rebound.
Differentiated Reactions Across Industrial Clusters
Feedback from major production hubs shows that traders in Jiangsu and Zhejiang (Shaoxing, Xiaoshan, Shengze) remain cautious, keeping inventory levels at a low 15-day supply. In Fujian's Changle and Guangdong's Shantou—regions concentrated on knitted yarn—PSF procurement volumes fell by 8% to 10% month-on-month, reflecting pressure from end-use garment orders. In contrast, inland cotton-spinning areas like Hubei and Henan show relatively inelastic demand for PSF due to substitution effects, with lower price sensitivity than coastal clusters.
This regional divergence means that further PSF price trends will depend heavily on the recovery pace of final consumption. If the traditional peak season orders in Q3 fail to materialize, destocking pressure in coastal clusters may force PSF plants to cut prices, triggering another round of downward movement. Conversely, if export orders improve or domestic consumption stimulus policies take effect, the current mid-range price could become a temporary bottom.
