The thermometer of the polyester filament market pointed to freezing on September 2: the average sales-to-output ratio among sample enterprises stood at only 39.1%, down 0.7 percentage points from the previous trading day. In plain terms, for every 100 tons of filament produced, fewer than 40 tons were purchased downstream. What makes this more intriguing is that manufacturers generally raised their quotations, yet the center of transaction prices failed to rise in tandem—rising prices coexisting with sluggish trading reveals a deep-seated tug-of-war along the chemical fiber supply chain.
Market Context
The sales-to-output ratio is a hard indicator of real demand in the chemical fiber market. A reading of 39.1% has now remained below the breakeven line for several consecutive trading days, and on that day, more than 60% of sample enterprises recorded ratios below 30%. A few even reported zero transactions, with only one company logging a bright 310% figure—but a single outlier cannot support the broader picture. This extreme divergence suggests that demand is not universally weak but highly concentrated in a small number of low-priced or differentiated products.
The paradox of rising quotations alongside cold trading essentially reflects a standoff between cost-push pressures and weak demand. If upstream raw material prices remain firm, polyester filament manufacturers see their profit margins squeezed, making price hikes a reluctant necessity. But downstream weaving mills, faced with high-priced raw materials, show little willingness to purchase, with local buyers only making small replenishments while the majority retreat to the sidelines. This “the higher the price, the less we buy” mentality is intensifying the market deadlock.
Industry Impact
A sales-to-output ratio below 40% carries significant transmission effects along the supply chain. For polyester filament factories, inventory pressure is quietly building. If the ratio stays below 100% for an extended period, it means production is outpacing sales, and inventory days are being passively extended. Should cash flow become strained, factories may be forced to offer promotional discounts, breaking the price deadlock—but at the cost of further profit erosion.
For downstream weaving enterprises, the current wait-and-see strategy can mitigate the risk of price drops in the short term. However, if raw material prices genuinely rise due to cost pressures, delayed purchasing could mean higher input costs later. Especially with the traditional “golden September, silver October” peak season approaching, the contradiction between order delivery pressure and insufficient raw material inventory may force some companies to enter the market earlier than planned.
The transmission in the foreign trade segment is even more complex. Fluctuations in polyester filament prices directly affect the price competitiveness of fabric exports. Under the current price standoff, foreign trade firms face a dilemma when taking orders: quoting at current prices risks customer demands for renegotiation if raw materials subsequently fall, while a rise in raw materials would erode their own profits. This uncertainty is significantly lengthening the order confirmation cycle for export contracts.
It is also worth noting the regional divergence in the offtake data. The distribution of sales-to-output ratios among sample enterprises shows that the individual figure of 310% may be related to a company’s product mix or client base, rather than signaling an overall market recovery. Buyers who base their trend judgments solely on isolated data points risk misreading the market.
