On August 4, spot prices for polyester POY (pre-oriented yarn) in China fluctuated between 8,250 and 8,550 yuan per ton, a spread of 300 yuan. For the same specification (150D/48F, semi-dull, first-grade), such a clear price stratification across major Zhejiang fiber production bases signals more than market volatility—it points to an internal structural adjustment within the industrial belt.
The Logic Behind Price Divergence
According to public quotes, Tongkun Group's Hengteng Differential Fiber led at 8,550 yuan per ton, followed by Kaishi Group at 8,450 yuan, while Rongsheng Petrochemical and Juxing Chemical Fiber reported lows of 8,250 yuan. Shenghong Chemical Fiber and Jiabao New Fiber sat in the middle at 8,350 yuan. This tiered distribution suggests that leading enterprises are consolidating their presence in the high-end market through differentiated pricing, while some manufacturers are choosing to trade volume for cash flow.
The widening spread directly reflects differences in raw material cost transmission. Upstream PTA and MEG prices have been volatile due to crude oil fluctuations, causing inventory cost disparities among producers. Companies with long-term contracts or low-cost inventories can maintain higher quotes, while those relying on spot purchases see their margins squeezed.
Impact on Downstream Procurement and Foreign Trade
For downstream weaving enterprises, the price divergence offers bargaining room. Buyers can reassess their product positioning based on different supplier quotes. If they prioritize quality stability, Tongkun or Kaishi's premium products suit high-end fabric needs; if cost control is key, Rongsheng or Juxing's quotes are more attractive. This choice effectively transmits market pressure upstream, forcing POY producers to optimize efficiency.
On the foreign trade front, POY prices directly affect cost calculations for export orders. The current spread may make exporters more cautious, favoring short-term floating price contracts with suppliers to hedge against raw material volatility. Meanwhile, Zhejiang's role as a global chemical fiber production base means its price movements often serve as a benchmark for international buyers; this divergence could prompt overseas clients to reassess supply stability.
Structural Adjustment in the Industrial Belt
The chemical fiber clusters in Xiaoshan and Shaoxing, Zhejiang, are undergoing a critical transition from scale expansion to quality-driven growth. The price divergence is a microcosm of this shift. Tongkun's premium strategy is backed by its technological expertise in differential fibers, while Rongsheng's low pricing may be paving the way for new capacity. In the short term, this looks like price competition; in the long run, it foreshadows increased industry concentration.
For small and medium POY producers, the 300-yuan gap intensifies survival pressure. Those unable to build advantages in cost or product differentiation risk being consolidated. Public industry data shows that polyester filament capacity has been increasingly concentrating among leading players, and this pricing dynamic may accelerate that process.
