On September 3, the average sales-to-production ratio of sampled polyester filament enterprises fell sharply to 25.8%, down 13.3 percentage points from the previous trading day—a figure that stands out in recent market activity. The sales-to-production ratio serves as a barometer of real demand; when it drops below 30%, it means that for every 100 tons of polyester filament produced, over 70 tons fail to convert into actual sales. This is not merely a matter of inventory accumulation but a signal that the game between upstream and downstream has entered a new phase.
Signals Behind the Data The disclosed data show a wide dispersion in daily sales-to-production ratios, ranging from 0% to 90%. A 0% ratio indicates virtually no transactions for some enterprises that day, while the 90% sample may benefit from specific orders or customer structures. However, the overall average of only 25.8%, down 13.3 percentage points from the previous day, reflects not random fluctuation but a systematic contraction in downstream purchasing willingness.
High polymerization costs are the core driver behind the recent price increases. Polyester filament producers have chosen to raise prices in tandem to pass on cost pressures, but this strategy has met with obvious resistance from downstream users. Weak buying interest has directly led to lower sales-to-production ratios, creating a cycle of "cost-push inflation, demand resistance, and shrinking transactions." If this stalemate persists, upstream companies will be forced to choose between production cuts to support prices or price reductions to stimulate sales.
For weaving enterprises, current procurement decisions are no longer simple price comparisons but bets on future cost trends. Behind the resistance lies downstream skepticism about the sustainability of high raw material prices and concerns about their own finished goods inventory turnover. If end-order demand cannot support high raw material prices, downstream will not readily accept them, even if polymerization costs remain high.
Industrial Game Under Price Stalemate The price game between polyester filament and downstream weaving is essentially a struggle over profit distribution. With high polymerization costs, upstream profit margins are compressed, strengthening their desire to raise prices. However, downstream users face difficulties in passing on their own product prices and are highly sensitive to raw material increases. This two-way squeeze has left the market in a "quoted but not traded" dilemma.
Historical patterns suggest that sales-to-production ratios persistently below 30% often herald a price inflection point. If downstream resistance continues, upstream companies may be forced to concede on pricing to stimulate transactions, potentially triggering a price correction. Conversely, if polymerization costs continue to rise and are supported by end demand, current prices may become the new normal. Buyers should closely monitor subsequent sales-to-production ratio trends as a key reference for adjusting procurement pace.
It is worth noting that the divergence among sampled enterprises is significant; some still maintain relatively high transaction levels, indicating that the market is not universally shrinking but rather structurally divided. Enterprises with product differentiation advantages or stable customer relationships are less affected. This reminds industry participants that during downturns, customer loyalty and product added value become critical to weathering risks.
Practical Recommendations
For Procurement Managers - Incorporate the sales-to-production ratio into daily monitoring; if it remains below 30% for three consecutive days, adopt a wait-and-see approach or small-batch replenishment to avoid overstocking during price stalemates. - Leverage the current buyer's market to negotiate more flexible settlement terms or deferred pricing clauses with suppliers, shifting some price risk upstream. - Monitor polymerization cost trends; if raw material prices such as PTA or MEG show signs of easing, consider postponing large orders to wait for a more favorable entry window.
For Weaving Factories - Optimize raw material inventory structure, maintaining a safety stock of 7-10 days to avoid cost inversions caused by raw material price volatility. - Strengthen the linkage between greige fabric and finished order management, prioritizing long-term orders with clear pricing terms to reduce raw material price exposure. - Establish information-sharing mechanisms with upstream suppliers to secure more favorable purchase prices or payment terms during periods of low sales-to-production ratios.
The current stalemate in the polyester filament market is an inevitable result of dual pressures from costs and demand. For all parties in the value chain, rather than passively waiting for prices to become clear, it is wiser to proactively adjust business strategies and seek certainty amid volatility. Though small, the sales-to-production ratio is the most direct window into the industry's warmth and cold.
