Sharp Drop in Polyester Filament Yarn Sales: The Cooling Period After Downstream Stockpiling and Market Rebalancing

On July 10, trading in the polyester filament yarn market cooled sharply. According to public industry data, the average sales-to-production ratio of sample enterprises stood at only 35.5%, a steep decline of 4.9 percentage points from the previous trading day. This figure directly reflects that after completing concentrated stockpiling, downstream users quickly shifted to a wait-and-see stance, ushering in the typical 'calm after the procurement pulse.'

Event Background

The distribution of specific data reveals extreme divergence: among 21 sample enterprises surveyed, 13 reported a sales-to-production ratio below 30%, with one even recording zero transactions. Only one enterprise achieved a relatively high ratio of 70%, while most others hovered between 30% and 40%. This distribution suggests that downstream demand is not universally shrinking but is highly selective—possibly tied to specific specifications, quality, or price advantages. Nonetheless, overall buying sentiment has clearly dissipated.

As a key upstream raw material in the textile supply chain, the sales-to-production ratio of polyester filament yarn serves as a direct barometer for demand intensity in downstream weaving, apparel, and other sectors. This sudden drop comes during a sensitive period when the traditional off-season for textiles overlaps with raw material price fluctuations. The earlier round of concentrated stockpiling likely stemmed from concerns over raw material price hikes or urgent delivery of short-term orders. However, after stockpiling, the sustainability of end-user orders failed to keep pace, causing demand to dry up rapidly.

Industry Impact

For polyester filament yarn manufacturers, a sales-to-production ratio of 35.5% implies rapidly accumulating inventories. According to industry experience, if the ratio persistently falls below 50%, inventory pressure will intensify significantly within two weeks, prompting factories to adjust operating rates or launch price-reduction promotions. On the cost side, upstream PTA and MEG prices have remained relatively stable recently, but weak downstream demand has weakened the ability to pass through costs, squeezing factory profit margins from both ends.

For downstream weaving enterprises, the current wait-and-see attitude reflects uncertainty about future raw material price trends. If polyester filament yarn producers cut prices to reduce inventories, downstream players may gain lower procurement costs. Conversely, if upstream firms hold prices firm, downstream players will have to maintain low inventory operations while awaiting clearer signals. This tug-of-war will amplify short-term market volatility and hinder stable supply chain operations.

From a longer-term perspective, the sharp fluctuation in July's sales-to-production ratio is not an isolated incident. Reviewing data from late June to early July reveals similar patterns of pulse-like procurement followed by rapid retreats. This underscores a lack of sustained growth in downstream demand, with limited recovery in end-use consumer markets such as apparel and home textiles, prompting all supply chain links to adopt a cautious 'fast-in, fast-out' approach.

Practical Recommendations

For Buyers - Given the prevailing wait-and-see sentiment, maintain low inventory levels and prioritize consumption of existing stocks. Avoid chasing replenishment when the sales-to-production ratio is low. - Closely monitor inventory days and operating rates of polyester filament yarn factories. If inventory pressure continues to rise, a price softening window may open within the next 1-2 weeks. - Establish flexible order terms with suppliers, such as phased deliveries or shortened price lock-in periods, to hedge against short-term price volatility.

For Factories - Timely adjust production plans by moderately reducing operating rates to align with current weak demand, preventing excessive inventory buildup that strains cash flow. - Optimize product mix by shifting capacity toward specifications or differentiated products with relatively higher sales-to-production ratios, reducing output of commoditized products. - Strengthen communication with downstream customers to understand their end-order status, enabling proactive prediction of the next replenishment cycle and avoiding reactive price cuts.
