The July 9 sales data sent a clear signal to the chemical fiber market: the average sales-to-output ratio of polyester filament sample enterprises fell to just 40.4%, a dramatic drop of 63.2 percentage points from the previous day. After a concentrated restocking session on July 8, the market almost overnight shifted from 'panic buying' to 'wait and see,' with most buyers retreating and only a few continuing to replenish.
Structural Divergence in Sales Data
Looking at the specific data from 24 sample enterprises, the distribution of sales-to-output ratios is highly uneven. The top two reached 180% and 120% respectively, but more than 60% of enterprises had ratios below 40%, with two as low as 10%. This 'high at both ends, collapsed in the middle' pattern indicates that restocking demand was not broad-based but concentrated in a few enterprises or specific product specifications.
More importantly, the median sales-to-output ratio was only 35%, far below the industry's typical breakeven line of 80%-100%. This means that even considering the concentrated transactions from the previous day, the actual absorption capacity of the entire polyester filament market remains weak. Downstream weaving mills have not changed their assessment of end-user demand just because of one restocking event.
Rational Correction After Concentrated Restocking
While the July 8 sales data was not publicly disclosed, the magnitude of the July 9 drop suggests that a significant concentrated restocking likely occurred on July 8, possibly triggered by upstream raw material price fluctuations or short-term promotions. However, this impulsive procurement did not translate into sustained demand. Texcircle Editorial believes this reflects the core logic of downstream enterprises: 'buy on dips, take profits, and stop.'
From a supply chain perspective, polyester filament is the core raw material for weaving. The sharp drop in sales ratios means weaving mills have no immediate incentive to place additional orders. If this wait-and-see sentiment persists for more than a week, upstream polyester plants will face rising inventory pressure, potentially forcing price cuts or production reductions to balance supply and demand.
Practical Implications for Procurement and Production
The current market is in a typical 'destocking observation period.' After replenishing raw material inventories from a low point on July 8, downstream enterprises are in no hurry to restock again, while terminal apparel orders show no clear signs of recovery. This suggests that the polyester filament market will likely maintain a pattern of 'low sales and weak prices' through mid-to-late July.
For Procurement Managers - Extend the procurement cycle for regular raw materials from weekly to ten-day intervals to avoid stockpiling during price stability. - Monitor polyester plants' weekly inventory reports; if inventories rise for two consecutive weeks, wait for a price drop window before entering the market. - Maintain flexible inquiries for differentiated products (e.g., high-filament-count, cationic modified yarns), as sales divergence means some specifications may still face supply gaps.
For Mills - Prioritize production for existing orders and suspend stockpiling for anticipated demand to avoid finished goods inventory buildup. - Use the current low-sales period for equipment maintenance or product changeovers, reducing operating rates to match actual shipment speeds. - Establish tighter inventory-sharing mechanisms with downstream customers to reduce severe sales fluctuations caused by information asymmetry.
This round of sales volatility in the chemical fiber market is not an isolated event. Looking back at June data, a similar pattern of 'one-day surge followed by next-day decline' appeared multiple times, indicating that inventory management across the entire chain is entering a new phase of high-frequency adjustments. For industry participants, adapting to this rhythm change is more important than betting on single price moves.
