The sales data on September 4 poured cold water on the polyester filament market: the average sales-to-production ratio of sample enterprises was only 21%, down 4.8 percentage points from the previous trading day. What does this number mean? Simply put, for every 100 tons produced, only 21 tons were sold that day, with over 70% of output turning into inventory pressure. Downstream users' resistance to high-priced raw materials has not subsided, rigid demand purchases are the only support, and market transactions have fallen into an unusual sluggishness.
Signals Behind the Data
Looking at the distribution of sales data released that day, the sales-to-production ratios of sample enterprises ranged from 0% to 40%, forming a clear polarization. The coexistence of extreme values of 0% and 40% indicates significant differences in the market game positions of enterprises of different scales and product structures. Some enterprises maintained relatively high sales ratios through differentiated products or customer loyalty, while enterprises with conventional products almost came to a standstill. This differentiation is not accidental but a typical manifestation of the ability to resist risks determined by product structure and customer relationships as the chemical fiber industry enters a mature stage.
The continuous decline in the sales ratio is not caused by a single factor. Since late August, polyester filament prices have continued to rise, with obvious cost push from raw materials. However, downstream weaving enterprises, facing high-priced raw materials, generally choose to purchase on demand and reduce inventory. This state of "neither high nor low" is essentially a game between upstream and downstream over price expectations: upstream wants to pass on costs through price increases, while downstream uses low purchase volumes to force upstream concessions.
Squeeze of Cost Transmission and Weak Demand
The direct driver of polyester filament price increases is the rise in polyester raw material costs. PTA and ethylene glycol, as major raw materials, have recently experienced price fluctuations that directly transmit to the filament sector. However, cost-side support has not effectively translated into downstream purchasing enthusiasm. Terminal textile and apparel demand is weak, weaving enterprises have insufficient orders, and their ability to afford high-priced raw materials is limited. The industry chain presents a typical pattern of "rising costs, weak demand," with intermediate polyester filament producers forced to balance between costs and demand.
Under such circumstances, the production-sales pressure on polyester filament enterprises will gradually accumulate on the inventory side. If the sales ratio remains low, rising inventory will force enterprises to alleviate pressure through price cuts or production reductions. Historical experience shows that if the sales ratio remains below 30% for more than a week, it often indicates the opening of a price adjustment window. The current 21% sales ratio is already in the warning zone, and the sales data for the coming week will become a key indicator for judging price trends.
Structural Opportunities in the Stalemate
Despite the overall sluggish market, structural opportunities still exist. Data shows that some enterprises still achieve a sales ratio of 40%. Such enterprises typically possess the following characteristics: high product differentiation, such as functional or fine-denier products; stable customer relationships with a large proportion of long-term cooperation orders; or smooth export channels that can divert domestic inventory pressure. For purchasers, this means that in a general decline, there are still some cost-effective or high-value-added supplies to choose from.
Another signal worth noting is that fluctuations in sales data often accompany extreme market sentiment. When the sales ratio drops to freezing point, some traders begin to test bottom-fishing, which injects liquidity into the market. For polyester filament enterprises, the key at this moment is to calmly judge: whether to continue the high-price strategy, sacrificing sales ratios for profit margins, or to moderately concede profits and accelerate inventory destocking. Both options have pros and cons, but the core lies in predicting future demand.
Practical Recommendations
For Purchasers - Under current high-price resistance, appropriately slow down procurement pace, maintain rigid-demand inventory, and wait for price corrections, but be alert to price rigidity caused by continued raw material cost increases. - Monitor continuous sales data. If the sales ratio rebounds above 30% for three consecutive days, it may indicate price stabilization; consider building positions in batches. - Negotiate with suppliers for a combination of long-term contracts and spot purchases, leveraging the current sluggish market to obtain more favorable settlement terms or logistics support.
For Factories - Strictly control product inventory, prioritize production of varieties with order support, and reduce passive accumulation of conventional products. - Utilize the low sales period for equipment maintenance and production process optimization, preparing for the next round of demand recovery. - Strengthen communication with downstream customers to understand the real situation of terminal orders, avoid blindly following price adjustments, and consider launching small-batch customized services to activate some demand.
Every trough in the chemical fiber market is an opportunity for industrial adjustment. The 21% sales ratio is indeed worrying, but it also reminds all participants that only through flexible response and precise positioning can they navigate through cycles in the supply-demand game. In the coming week, the direction of polyester filament prices will depend on inventory digestion speed and cost-side changes. All parties in the industry chain need to closely track sales data and adjust business strategies in a timely manner.
