On August 31, the average sales-to-production ratio of polyester filament sample enterprises reached 82.8%, up 48.1 percentage points from the previous trading day—a rare single-day surge in recent sales statistics. However, the underlying data reveal a wide dispersion: from highs of 135%, 200%, and 260% to lows of 40% and 50%. This is not a synchronized recovery but a divergent game among enterprises of different scales and order structures under cost anxiety.
Divergence Behind the Numbers
The sales-to-production ratio measures how much of a day's output is sold; a ratio above 100% indicates that sales exceeded production, typically signaling inventory drawdown. On August 31, some enterprises achieved ratios as high as 260%, while others lagged at 40%—a six-fold gap. Such extreme divergence suggests that the market did not see a broad-based pickup; instead, certain players captured limited incremental demand through pricing advantages or customer loyalty.
Industry-wide, an 82.8% ratio still sits below the 100% breakeven line, meaning destocking is incomplete. Yet the 48.1-percentage-point jump indicates a significant activation of downstream purchasing intent. Notably, about half of the sample enterprises reported ratios between 50% and 80%, implying that most are still on the slow lane of inventory reduction, with only a few leaders achieving above-par sales.
Cost-Side Support and the Hoarding Logic
The immediate driver of the surge is cost-side support. Rising raw material prices lifted production costs, prompting manufacturers to adopt a low-price, hold-back sales strategy—preferring to reduce shipments rather than sell at prices that would erode margins. This is reflected in the lower ratios (40%, 50%) among some enterprises that deliberately controlled sales pace, waiting for a better price window.
Meanwhile, downstream users' fears of rising future procurement costs were ignited. Faced with upward raw material price expectations, weaving mills opted for small, incremental replenishments to lock in current relatively low costs, rather than building large inventories. This "ant-like" purchasing behavior explains both the overall recovery and why most enterprises hovered between 50% and 80%—downstream is still testing the waters, not yet committing to safety stock.
Short- and Medium-Term Implications for the Chain
In the short term, the ratio recovery helps ease inventory pressure for polyester filament makers, especially those with ratios above 100%, whose destocking will accelerate. But the divergence means pressure is not uniformly released; some SMEs may still face high inventory turnover days.
Medium-term, if cost-side strength persists, polyester filament prices are likely to find support, and manufacturers' hoarding sentiment may continue, pushing the price center of gravity upward. This poses cost pressure on downstream weaving mills, potentially squeezing their margins and even causing order delays or reductions. Foreign trade firms need to monitor the linkage between exchange rates and raw material costs to avoid signing fixed-price contracts during the cost transmission lag.
