7,500 yuan/ton—that's the anchor price for Jiangsu's polyester staple fiber (PSF) spot market on July 17. On the surface, it reads as 'stable,' but beneath lies a delicate balance of upstream-downward bargaining. The negotiation range of 7,450-7,600 yuan/ton, with isolated deals as low as 7,300 yuan/ton, signals expanding buyer leverage, yet sellers remain reluctant to concede.
The Cost-Demand Tug-of-War
PSF pricing logic begins with raw materials. PTA, the key upstream, has recently oscillated within a narrow band due to PX volatility, offering PSF mills some cost buffer. The real pressure comes from downstream. Weaving and spinning capacity utilization typically dips in July's off-season, with small and medium-sized mills in Jiangsu and Zhejiang reducing output or rotating shifts. This leaves PSF procurement focused on restocking for immediate needs, with speculative hoarding virtually absent.
This means the 'stability' at 7,500 yuan/ton reflects not supply-demand equilibrium but a standoff: upstream refuses to cut, downstream refuses to chase. Should PTA shift direction or terminal orders fail to improve before August, this price platform could quickly erode.
Industrial Chain Transmission
Jiangsu, one of China's largest PSF production hubs, transmits price signals swiftly to downstream clusters like Shengze, Nantong, and Shaoxing. The lower end of the current negotiation range has touched 7,300 yuan/ton—a level where cost-efficient mills can still break even, but for smaller enterprises reliant on purchased raw materials, profit margins are squeezed to the breaking point.
Historical data shows 7,300 yuan/ton approaches the 12-month low band. In the same period of 2025, the average PSF price in Jiangsu was about 7,800 yuan/ton, meaning the current price is roughly 3.8% lower year-on-year. While modest, this decline, combined with the industry's overcapacity, could trigger chain reactions—especially if traders begin destocking.
Buyer Strategy
For fabric and yarn buyers, the current market offers an observation window. In the short term, prices near 7,300 yuan/ton carry some safety margin, but two risks warrant caution: first, if crude oil declines drags PTA lower, PSF could follow; second, if downstream orders remain weak, inventory will tie up capital and storage.
A key signal: since July, PSF sell-through rates have hovered between 50% and 70%, below the 80% breakeven line. This suggests mill inventories are building, and price cuts to clear stock are possible within the next two weeks.
Export and Supply Chain Variables
On the export front, Southeast Asian textile demand for PSF remains steady, but RMB exchange rate fluctuations and rising freight costs are squeezing margins. Jiangsu's PSF export price averages around $800/ton (FOB), about 8% above domestic spot. If this spread narrows, export momentum will weaken, adding domestic supply pressure.
