The spot price of polyester staple fiber in Jiangsu dropped by 70 yuan per ton on July 2, settling at 7,130 yuan per ton. Transaction ranges concentrated between 7,100 and 7,150 yuan, with some low-end lots falling to 6,860 yuan—a level rarely seen in the past three months. The decline not only breached the psychological 7,200 yuan mark but also approached the cash cost line for many small and medium-sized producers.
Cost Weakness Is Only the Trigger
Falling crude oil prices have reduced feedstock costs for PTA and MEG, thereby lowering polyester staple fiber production expenses. However, cost-side easing alone cannot explain such a sharp single-day drop. The real pressure came from downstream weaving mills and yarn spinners tightening their procurement pace. In Jiangsu and Zhejiang, operating rates at small and medium-sized weaving mills dipped in late June, with many mills choosing to consume existing inventories rather than restocking, directly weakening spot liquidity.
Quotation Divergence Reveals Structural Risks
The 7,100-7,150 yuan negotiation range appears narrow, but the 6,860 yuan low-end quote sends two signals: first, some holders face capital pressure and are eager to sell for cash; second, the market is experiencing quality or channel differentiation, with lower-grade products under more severe downward pressure than mainstream brands. For buyers, this creates both opportunity and risk—low prices may be accompanied by quality fluctuations, requiring stricter inspection procedures.
Direct Impact on Downstream Procurement
The price decline benefits spinners and nonwovens producers most directly. At current levels, raw material costs per ton of yarn can drop by about 70-80 yuan. For low-margin products like pure polyester yarn or polyester-cotton blends, this reduction can create a 2-3% price advantage in order quotations. However, if crude oil continues to fall, PSF prices may not have bottomed out, making large-scale stockpiling at current levels risky.
Inventory and Demand Game Is Escalating
This price drop is a microcosm of the broader destocking cycle in the chemical fiber industry. Rapid capacity expansion in the polyester chain during the first half of the year has kept supply elevated, while end-apparel export orders have not recovered as strongly as expected. The supply-demand gap is widening. As an intermediate product, PSF price fluctuations reflect the concentrated release of upstream cost pressure and downstream demand weakness in the spot market.
