On August 4, trading in the polyester filament market hit a freezing point. The average sales-to-output ratio among sample enterprises fell to 30.9%, down 2.7 percentage points from the previous trading day, meaning nearly 70% of the day's output failed to convert into actual transactions. Downstream users' resistance to high-priced raw materials is evolving from verbal complaints into substantive procurement pauses.
Background
The sales-to-output ratio is a core leading indicator of the chemical fiber market. A reading of 30.9% sits at the lower end of the past three years, reflecting insufficient end-demand support at current prices. The sample data reveals extreme divergence, with individual ratios ranging from 0% to 340%—a few enterprises achieved above-average sales through differentiated products, while most conventional grades faced zero transactions.
This divergence is not accidental. Conventional polyester filament is highly homogeneous with transparent pricing, giving downstream weaving mills strong bargaining power. In contrast, differentiated products (e.g., cationic, high-elasticity yarns) have more concentrated supply, so even with high prices, rigid-demand orders sustain higher ratios. In other words, the market is not shrinking across the board but is structurally uneven.
Industrial Impact
Persistent low ratios first pressure inventory turnover at polyester plants. At the current pace, sample enterprises' inventory days are passively accumulating. If this trend continues, plants will face a choice between price cuts to destock or output cuts to support prices. Historically, when the ratio stays below 40% for three consecutive days, polyester plants likely launch promotions or maintenance plans to balance supply and demand.
For downstream weaving mills, the current wait-and-see approach avoids short-term high-price risks but harbors the risk of missing restocking opportunities. Once upstream output cuts tighten supply, prices may rebound quickly, making chase-buying costs higher than current concessions. Thus, buyers must balance "waiting for drops" and "locking prices" rather than betting one-sidedly.
Notably, the ratio also signals cash-flow stress. Low ratios mean slower cash recovery, putting small and medium polyester enterprises under greater liquidity pressure. This may accelerate industry consolidation, allowing financially strong leaders to expand market share while outdated capacity without cost control exits.
Practical Recommendations
For Buyers - Batch purchasing: Avoid one-time bulk purchases; adopt a "small batches, high frequency" strategy to gradually replenish inventory during price dips, reducing average cost risk. - Monitor inventory and operating rates: Closely track polyester plants' inventory days and maintenance plans; if inventory peaks and output-cut news lands, treat it as a price bottom signal. - Lock differentiated products: For filament types needed in high-value fabrics, sign long-term agreements with suppliers in advance to avoid passive price hikes during supply tightness.
For Foreign Trade Companies - Shorten quotation cycles: During volatile periods, reduce quote validity from 30 days to 7-10 days to protect margins from raw material hikes. - Hedge currency risk: For import orders settled in USD, monitor RMB exchange rate fluctuations and use forward settlement tools to lock costs. - Tiered client management: Offer price protection clauses to long-term partners; use floating quotes for short-term inquiries to balance relationships and profitability.
The current adjustment in the polyester filament market is essentially a re-matching process between price and demand. Short-term pain is inevitable, but if all chain links optimize inventory and procurement strategies accordingly, they can seize the initiative in the next upward cycle.
