Polyester Staple Fiber Price Hovers Near Median, Chemical Fiber Market Awaits Directional Signals

The chemical fiber market entered the third quarter of 2026 with unusual quietness. The benchmark price of polyester staple fiber (PSF) continued to soften over the past month, reaching 7255.83 RMB/ton on July 6, down 2.19% from 7418.65 RMB/ton at the start of the month. This price level sits exactly at the median of its one-year range, triggering neither panic buying among downstream users nor large-scale production cuts at mills.

Price Position and Market Sentiment

Looking at the annual statistical range, PSF prices have fluctuated sharply over the past 12 months, hitting a high of 8426.02 RMB/ton and a low of 6267.17 RMB/ton, a spread of 2158.85 RMB/ton. The current price of 7255.83 RMB/ton is near the median value of 7346.6 RMB/ton, with a gap of 1170.19 RMB to the top and a buffer of 988.66 RMB to the bottom.

This position creates a subtle psychological game for both buyers and sellers. For chemical fiber mills, the price has moved above the annual average of 6971.19 RMB/ton, so current profit margins, while not as fat as during the peak, are still not loss-making. For weaving and texturing enterprises, the price is neither cheap enough to justify large-scale stockpiling nor high enough to force urgent cost locking.

Supply-Demand Weak Balance

The sideways movement of PSF prices in early July is not an isolated phenomenon. Upstream raw materials PTA and MEG also lack direction, with crude oil hovering around $70 per barrel, providing limited cost support. On the downstream side, garment export orders have entered a traditional slow season, demand from the home textile market is lackluster, and weaving mill operating rates generally remain at 60-70%, with no obvious restocking impulse.

Notably, with the price at the median, there is ample room for movement in either direction if cost-side volatility occurs. A geopolitical spike in crude oil could quickly push PSF prices toward 8000 RMB/ton; conversely, if demand continues to weaken, the risk of prices breaking below 6800 RMB/ton cannot be ruled out.

Inventory Signals from Industrial Clusters

Feedback from major textile clusters such as Keqiao and Shengze indicates that PSF social inventories are at a moderately high level. Traders generally adopt a fast-in, fast-out strategy and are unwilling to leverage inventory accumulation when the price direction is unclear. Some small chemical fiber mills have already begun to reduce operating rates to cope with sales pressure, but leading enterprises have not yet signaled significant production cuts.

This inventory structure means the market lacks a buffer function. If downstream orders show marginal improvement, prices could rebound quickly; but if the seasonal weakness deepens, the probability of prices breaking below the median range will increase.

Practical Recommendations

For Buyers - Adopt a small-lot, high-frequency purchasing strategy to avoid locking in high costs at once. - Monitor crude oil and PTA price changes; if cost-side volatility exceeds 2%, adjust procurement pace quickly. - Negotiate short-term floating price agreements with suppliers, shortening pricing cycles to within one week to cope with potential fluctuations.

For Chemical Fiber Mills - Maintain moderate operating rates to avoid increasing finished goods inventory amid unclear demand. - Use futures tools to hedge part of production capacity and lock in production margins. - Strengthen communication with downstream customers to understand actual order conditions and avoid passive inventory buildup.
