On September 2, the average sales-to-output ratio of polyester filament sample enterprises stood at 39.1%, down 0.7 percentage points from the previous trading day. This figure means that for every 100 tons of polyester filament produced, only about 39 tons found buyers—over 60% of output stayed overnight in warehouses. More intriguingly, most manufacturers raised their quotes that day, but the actual transaction price increases varied widely. A few users made small replenishments, while the majority retreated to the sidelines, resulting in a sluggish market. The paradox of rising prices alongside weak sales has become the most telling footnote of today's chemical fiber market.
Low Sales-to-Output Ratio: A Clear Signal of Weak Demand
The 39.1% ratio is not an isolated data point. The detailed figures released for sample enterprises show extreme divergence, ranging from 0% to 310%. The 310% extreme likely indicates that a particular enterprise achieved oversold status due to concentrated delivery of earlier orders or promotional pricing, but the numerous data points at 0%, 5%, and 10% point to a more general truth: the purchasing willingness of downstream weaving and texturizing enterprises has dropped to freezing point. When the sales-to-output ratio remains below 40% for consecutive days, it usually means that channel inventories are passively building up, and the recovery of end-user orders is far behind the expansion of supply.
This divergence is not accidental. Polyester filament capacity has been continuously released in recent years, while downstream demand, constrained by sluggish apparel consumption recovery and fluctuating foreign trade orders, has failed to form effective absorption. When supply growth outpaces demand, a declining sales-to-output ratio becomes inevitable. For factories, a low ratio directly raises inventory costs and squeezes cash flow, forcing some to offer discounts to gain liquidity, which in turn undermines the sustainability of price hikes.
Price Hikes and Wait-and-See: Broken Price Transmission Mechanism
The intention behind manufacturers raising quotes is often to signal downstream buyers to restock early, thereby alleviating their own inventory pressure. However, the market performance on September 2 showed this strategy did not work. The significant divergence in transaction price increases indicates that price hikes remained mostly at the quotation level, with actual transaction prices not following suit. Downstream users generally resisted high-priced supplies, and the sporadic replenishment was limited to essential specifications rather than speculative stockpiling.
This deadlock of "rising but not following" reflects intensified game-playing between upstream and downstream in the industrial chain. Upstream polyester plants, constrained by raw material costs and processing margins, have an inherent urge to raise prices to protect profits; but downstream weaving enterprises, squeezed by falling product prices and insufficient orders, have almost no capacity to absorb raw material price increases. When the price transmission chain becomes blocked in the middle, the market falls into a vicious cycle where the more prices rise, the more buyers wait. For procurement teams, this implies that any short-term quote increases may leave room for negotiation, rather than signaling an imminent supply crunch.
Regional and Varietal Divergence: Structural Opportunities Remain
Despite the overall low sales-to-output ratio, the sub-segment data still reveals structural clues. Sample enterprises with a ratio as high as 310% are likely concentrated in differentiated varieties or tight specifications, while conventional POY, FDY, and DTY products generally moved slowly. This suggests the market is not shrinking across the board; rather, demand is shifting toward high-value-added and functional products. Meanwhile, different regional industrial clusters show varying operating rates and procurement rhythms. Some export-oriented weaving bases, buoyed by recovering orders, have shown significantly higher willingness to stock up on raw materials than regions dependent on domestic sales.
For upstream factories, rather than exhausting market trust through blanket price hikes, it may be wiser to increase investment in new product development and customized services, using product strength to hedge against cyclical fluctuations. For downstream users, the current wait-and-see sentiment does not mean they can completely stop purchasing—a low sales-to-output ratio often coincides with price troughs. Moderately locking in essential supplies at low prices may be more pragmatic than waiting for the absolute bottom.
