On September 4, the trading atmosphere in the polyester filament yarn industry hit a freezing point, with the average sales-to-output ratio of sample enterprises at only 21.0%, a sharp drop of 4.8 percentage points from the previous trading day. Behind this figure lies the continued resistance of downstream users to high raw material prices, with purchases shrinking almost entirely to rigid demand. The chemical fiber market is experiencing a deep deadlock caused by the game between costs and demand, and its transmission effects along the industrial chain deserve vigilance from every practitioner.
Event Background
The sales-to-output ratio is a barometer measuring the ratio of actual sales volume to production output on a given day. An average of 21% implies that nearly 80% of the day's output failed to translate into effective sales, with the risk of passive inventory accumulation mounting. Public sub-data shows a highly dispersed distribution from 0% to 40%, with many clusters in the 10%-20% range and only a few enterprises reaching 40%. This divergence reflects significant differences in customer structure, product differentiation, and pricing strategies, signaling that intra-industry reshuffling may accelerate.
Notably, this decline is not an isolated event. Reviewing data from previous trading days, the polyester filament yarn market has been in a low sales-to-output state for several consecutive days, with no obvious recovery in downstream weaving operating rates, and terminal orders dominated by short and small batches. The scissors gap between high raw material prices and weak demand is squeezing profit margins across the entire polyester industrial chain. For polyester plants, price cuts may not effectively stimulate demand and could further strengthen downstream wait-and-see sentiment, while maintaining prices means bearing financial pressure from rising inventories.
Industry Impact
The direct impact of the low sales-to-output ratio is the passive extension of inventory days for polyester plants. Based on current sales levels, if demand does not effectively pick up in the coming days, inventory turnover days for some enterprises may exceed the 30-day warning line, forcing them to choose between production cuts or maintenance. While this supply-side self-regulation helps alleviate supply-demand contradictions, it may intensify raw material price fluctuations in the short term, transmitting bearish signals to upstream PTA and MEG markets.
For downstream weaving and garment enterprises, the current market environment demands more refined raw material procurement strategies. On one hand, rigid-demand procurement ensures production continuity but lacks cost advantages; on the other hand, excessive inventory reduction in anticipation of price drops risks cost overruns if raw material prices rebound suddenly. Against the backdrop of low sales-to-output ratios, price negotiations between upstream and downstream will become more intense, and payment terms and settlement methods may become new focal points of contention.
From a broader industrial belt perspective, operating rates in major polyester filament yarn consumption hubs such as Shengze, Changxing, and Xiaoshan have shown regional divergence. Some small and medium-sized weaving mills focused on conventional varieties are proactively reducing loads due to thin profits, while enterprises capable of developing differentiated products maintain relatively stable orders. This structural adjustment is essentially a correction of previous overcapacity expansion, creating a relatively favorable competitive window for enterprises with high-value-added product lines.
