On September 1, the average sales-to-production ratio of sampled polyester filament enterprises dropped to 39.8%, a sharp 43-percentage-point decline from the previous trading day's close. This figure contrasts sharply with the late-day surge in sales for some producers—reaching as high as 300-400%—and the subsequent price hikes across the market, which triggered immediate resistance from downstream users and a noticeable cooling in inquiries.
Background
This volatile fluctuation is not an isolated event. In the late trading session of the previous day, several polyester filament manufacturers saw significant sales volume, with some achieving ratios between 300% and 400%, indicating a phase of concentrated restocking demand. However, when most manufacturers raised their quotes, downstream users did not accept the increases and instead adopted a wait-and-see stance. On the day in question, the distribution of sales-to-production ratios among sampled enterprises showed that most operated in the 20-40% range, with only a few reaching 80% or 150%, reflecting generally subdued transaction activity.
This cycle of "surge in sales—price hike—resistance—shrinking volume" is not unfamiliar in the chemical fiber market, but the magnitude and speed of this adjustment deserve attention. A single-day drop of 43 percentage points in the sales-to-production ratio signals that market sentiment has shifted rapidly from short-term exuberance to caution, with price transmission encountering obstacles at the end-use level.
Industry Impact
The essence of the plunge lies in the widening divergence in price expectations between upstream and downstream players. Earlier rises in raw material costs had pushed up polyester filament production costs, prompting manufacturers to attempt passing on these costs through price increases. However, downstream weaving and garment enterprises, facing uncertainty in end-demand, have shown significantly lower tolerance for high-priced feedstock. This divergence is directly reflected in the sales data and suggests that upward price momentum may be limited in the near term.
For buyers, the current market is in a phase of "price-testing vs. buyer-waiting," where blindly chasing highs carries risk, but waiting entirely could mean missing opportunities to stock up at lower levels. For mills, weaker sales-to-production ratios imply that inventory pressure may re-accumulate, making cash flow management more critical than pursuing one-off price increases. For foreign trade companies, raw material price volatility directly impacts quote competitiveness, and mismatches between order cycles and procurement cycles could erode profit margins.
Notably, the data distribution reveals a divergence among enterprises. Some still achieve ratios of 80% or even 150%, indicating sustained demand for differentiated products, while conventional varieties face greater sales pressure. This structural split suggests that the market is not uniformly weakening, but rather that demand is concentrating toward higher value-added and differentiated offerings.
