On September 2, the polyester filament market delivered a thought-provoking result: the average sales-to-output ratio of sample enterprises stood at only 39.1%, down 0.7 percentage points from the previous trading day. Behind this figure lies a fierce tug-of-war between collective price hikes by manufacturers and widespread wait-and-see sentiment among downstream users, reflecting a deep divergence in expectations along the polyester supply chain.
Low Sales-to-Output Ratio: A Direct Indicator of Weak Demand
A ratio of 39.1% implies that for every 100 tons of polyester filament produced, only about 39 tons are absorbed by the market. Data from individual enterprises show extreme divergence, ranging from 0% to 310%. Some firms may have achieved over-sales due to long-term contracts or temporary replenishment, but more than 60% of sample enterprises recorded ratios below 50%, with several at zero. This polarization is not accidental; it mirrors weak end-user demand concentrated at the midstream of the industry chain.
More notably, the ratio continued to decline sequentially, indicating that downstream weaving mills are slowing their raw material inventory digestion and weakening their replenishment appetite. Traditionally, September is a stocking window before the peak season, but current data show no signs of seasonal recovery. This suggests that the 'golden September' may be less robust this year, a warning signal for chemical fiber traders and weaving factories that rely on seasonal demand.
Price Hikes vs. Wait-and-See: The Cost Pass-Through Dilemma
In sharp contrast to the declining sales-to-output ratio, most polyester filament manufacturers raised quotes on the same day. This 'counter-trend' price increase appears cost-pushed—upstream PTA and MEG prices remain high, squeezing polyester plants' margins. But on a deeper level, it may be an attempt to stabilize market expectations through price signals, avoiding a panic-driven inventory sell-off.
However, the divergence in transaction centers indicates that price hikes have not been widely accepted downstream. Limited small-scale replenishment by local users is more demand-driven than trend-following. The wait-and-see stance of most users reflects either their non-acceptance of current prices or expectations of future declines. This standoff implies that cost pressures cannot be smoothly passed downstream, forcing polyester plants to absorb some cost increases, thereby compressing their profits.
From an industrial transmission logic, if polyester filament prices fail to rise effectively, they will exert downward pressure on upstream raw material prices, creating a negative feedback loop. But if raw materials remain firm, polyester filament faces a deadlock where it can neither rise nor fall. For buyers, the current juncture requires more nuanced weighing of the risks of locking in prices versus waiting.
Event Impact: Regional and Chain-Wide Repercussions
Core polyester filament production areas are concentrated in Tongxiang, Shaoxing, and Shengze, where weaving mill operating rates and raw material purchasing rhythms directly determine the sales-to-output ratio. The current low ratio implies that downstream operations in these regions may be underutilized, or orders are predominantly short-term and small. This, in turn, affects polyester plants' inventory strategies—if sales remain sluggish, they may be forced to cut production or discount prices, triggering regional price adjustments.
For export-oriented textile enterprises, RMB exchange rate fluctuations and overseas inventory destocking cycles remain critical variables. September is typically a negotiation period for foreign trade orders, but overseas demand uncertainty makes order pacing difficult. Fluctuations in polyester filament prices directly impact the cost calculations of exported fabrics, requiring foreign trade firms to build greater flexibility into their quotes.
