On August 1, the average sales-to-production ratio of polyester filament sample enterprises dropped to 33.6%, down 3.8 percentage points from the previous trading day. This figure reflects a marked cooling in downstream restocking enthusiasm—after a weekend of concentrated purchasing, the market quickly turned cautious. For the entire industrial chain, this is more than a one-day data fluctuation; it may signal a shift in short-term demand momentum.
Market Sentiment Behind the Numbers
According to feedback from sample enterprises, the daily sales-to-production ratios varied significantly, ranging from a low of 0% to a high of 60%. More than half of the enterprises recorded ratios between 20% and 30%, with only a few reaching above 40%. This divergence indicates that not all manufacturers face the same sales pressure; some maintain higher shipments due to customer loyalty or differentiated products.
Overall, a 33.6% ratio means that sales volume was only about one-third of production, implying inventories are building passively. The previous trading day's figure stood at 37.4%, and the nearly 4-percentage-point drop within just one day highlights rapid shifts in market sentiment. Such volatility is not uncommon in the chemical fiber industry, but two consecutive days of weakening deserve attention.
Industrial Logic Behind the Weakening Ratio
The fluctuation in polyester filament sales-to-production ratio is essentially a reflection of downstream weaving enterprises' purchasing rhythm. Weekend concentrated restocking is often driven by expectations of future price increases or low raw material inventories. Once restocking is completed, the motivation for immediate additional purchases diminishes. The current decline is a typical manifestation of this logic.
A deeper cause lies in the support from end demand. Currently, it is the traditional off-season for textiles, with downstream orders mainly consisting of small and urgent batches. Weaving enterprises generally maintain low raw material inventory strategies. A weakening sales-to-production ratio implies rising inventory pressure for upstream polyester plants, which may force them to adjust pricing strategies, such as promotions or price reductions to stimulate shipments.
For upstream raw materials like polyester chips, changes in polyester filament sales-to-production ratios have a transmission effect. If filaments continue to accumulate inventory, plants will reduce purchases of chips, thereby affecting chip prices. Therefore, the sales-to-production data over the next week will be a key indicator for judging price trends across the industrial chain.
Short-Term Price Expectations and Operational Strategies
Historically, a sales-to-production ratio below 40% usually indicates downward price pressure. If the data show no improvement in the coming days, polyester filament manufacturers may resort to price cuts to alleviate inventory pressure. However, given the cost support from upstream PTA and MEG, the room for significant declines may be limited, and prices are more likely to drift lower.
For buyers, this is not the time to stockpile large quantities. Maintaining a low inventory strategy and purchasing as needed can help reduce raw material costs during a price downturn. At the same time, close monitoring of changes in the sales-to-production ratio is essential; a sustained rebound could signal a price stabilization point.
For mills, flexible production scheduling is key. During periods of weak demand, appropriately reducing operating rates and avoiding ineffective inventory accumulation is more important than merely pursuing output. Additionally, increasing the development of differentiated products can help mitigate the risk of price wars caused by homogeneous competition.
