The September 4 production-sales data cast a cold shower on the chemical fiber market. The average sales-to-production ratio of polyester filament sample enterprises fell to 21%, down 4.8 percentage points from the previous trading day. This figure means nearly 80% of production capacity failed to convert into actual transactions. When buyers are only willing to pay for essential needs, the carefully maintained price system of sellers is facing an unprecedented test.
Market Logic Behind the Data
The sales-to-production ratio is a barometer of supply-demand balance in the chemical fiber industry, and the 21% reading has touched the lower end of this year's range. Looking at the distribution among sample enterprises, ratios range from 0% to 40%, with some even recording zero transactions, indicating extreme divergence in demand. More alarming is that this data continues to decline from an already low base, suggesting no signs of stabilization.
Downstream resistance to high prices is not unfounded. Since late August, upstream raw material prices have strengthened, pushing up polyester filament quotations. However, terminal orders for apparel and home textiles have not rebounded simultaneously, leaving weaving enterprises struggling with cost transmission bottlenecks. When processing margins are squeezed to critical levels, purchasing decisions naturally turn conservative, making just-in-time procurement the mainstream strategy.
Chain Reactions Across the Industry
The persistently low sales-to-production ratio first impacts inventory management. At current sales rates, finished goods inventory days for sample enterprises are being passively extended. If this trend continues, polyester filament manufacturers will face pressure to cut prices to destock, potentially triggering a price correction that could break the current relatively rigid quotation pattern.
For upstream polyester chips, weak filament sales mean reduced motivation for raw material procurement. Chip suppliers may have to lower ex-factory prices to maintain shipments, further squeezing their profit margins. This bottom-up pressure transmission may reshape the profit distribution across the entire chemical fiber chain in the coming weeks.
From a regional industry cluster perspective, weaving enterprises in major polyester filament production areas such as Shengze and Changxing are closely monitoring raw material fluctuations. Some fabric merchants have begun adjusting their order-taking strategies, building larger price adjustment buffers into quotations to mitigate risks from future cost changes. If this cautious sentiment spreads to end users, it will further suppress demand release.
For foreign trade enterprises, exchange rate fluctuations and international oil price movements have become additional variables. As a downstream product of petroleum, polyester filament costs are highly correlated with international oil prices. If geopolitical tensions push up oil prices while demand remains weak, enterprises will face a dilemma between costs and orders.
