Polyester Filament Sales-to-Output Ratio Falls Below 40%: Price Hikes Fail to Spur Restocking, Market Turns Cautious

On September 2, the average sales-to-output ratio of polyester filament sample enterprises fell to 39.1%, down 0.7 percentage points from the previous trading day. This figure indicates that over 60% of the day's output was not converted into actual sales, signaling a silent accumulation of inventory pressure. More notably, despite synchronized price hikes by most manufacturers, the market did not see the expected volume increase. The coexistence of price increases and wait-and-see attitudes reflects a new phase of game-playing between upstream and downstream sectors.

Event Background

The released production-sales data showed extreme divergence: some enterprises recorded a ratio as high as 310%, while others reported zero. This polarization is not accidental; it mirrors differences in bargaining power among enterprises of varying sizes and product structures. Leading companies, leveraging product differentiation and customer loyalty, maintained higher shipment levels, while small and medium-sized enterprises lacking distinctive features faced dual pressures of order loss and inventory buildup.

On the price front, most manufacturers raised quotations, but the magnitude of transaction price increases varied significantly. This suggests that price hikes are more cost-push than demand-pull. Downstream weaving enterprises did not show panic buying in response to rising raw material prices; instead, they chose to wait and see, indicating divergent views on future price trends or insufficient orders to justify expanding raw material inventories.

Industry Impact

A sales-to-output ratio below 40% is generally regarded as a warning line for industry prosperity. For polyester filament producers, this implies slower cash flow recovery and increased capital occupation by inventories. If the trend continues, enterprises may be forced to cut prices to stimulate sales, squeezing profit margins. For the polyester chain, price support for upstream materials such as PTA and MEG will weaken, and cost transmission mechanisms may be hindered.

For downstream buyers, the current market environment offers negotiation leverage. With low sales-to-output ratios and rising inventories, sellers' bargaining power weakens, and buyers may secure more flexible payment terms and favorable prices. However, excessive wait-and-see may also miss windows for low-price restocking, especially when raw material prices have shown signs of increase. Timing of purchases becomes crucial.

From an industry structure perspective, the divergence in production-sales data intensifies market reshuffling. Small and medium-sized enterprises lacking capital strength and customer resources may face greater operational pressure, while leading companies are expected to expand market share through scale advantages and channel integration. This adjustment may benefit long-term healthy development, but in the short term, it could trigger partial capacity elimination and price fluctuations.

Practical Recommendations

For Buyers - Closely monitor the sales-to-output ratio and inventory days. When the ratio remains below 40% for three consecutive days, consider signing medium-term fixed-price contracts to hedge against potential price rebounds. - Leverage the window when sellers are eager to ship to request extended payment terms or additional quality compensation clauses, but be cautious of potential quality instability associated with low-priced sources.

For Manufacturers - Optimize product mix, reduce production of homogeneous products, and increase development of differentiated, high-value-added varieties to enhance resilience. - Establish a production-sales linkage mechanism, dynamically adjusting production loads based on daily ratios to avoid excessive inventory buildup. Additionally, consider using futures hedging tools to lock in long-term raw material costs and smooth price fluctuations.
