A 25.8% sample sales-to-output ratio and a 13.3 percentage point single-day drop—this is the alarming set of data from the polyester filament market in early September. Behind these numbers lies the dual squeeze of high costs and weak demand, a signal that the tug-of-war along the supply chain has entered a deeper phase.
What the Data Reveals
According to industry public data, the average sales-to-output ratio of sampled polyester filament enterprises on September 3 was only 25.8%, down 13.3 percentage points from the previous trading day. The breakdown shows ratios ranging from 0% to 90%, with most firms falling in the low 10%-30% range, and only a few reaching above 50%. This distribution indicates that weak demand is not an isolated phenomenon but rather widespread.
The sales-to-output ratio is a core metric measuring the match between daily sales and production. A ratio of 25.8% implies that over 70% of the day's output failed to translate into actual sales, meaning inventory pressure is building at the production end. Notably, this comes against a backdrop of persistently high polymerization costs, where cost-side support contrasts sharply with demand-side drag.
The Cost-Demand Tug-of-War
Persistently high polymerization costs are the direct reason polyester filament producers have chosen to follow price increases. In theory, cost-push price hikes are not uncommon in the polyester industry chain, but this time they have met strong downstream resistance. Market buying is thin, and transactions are scarce, indicating that downstream users have limited acceptance of high-priced raw materials and prefer to digest existing inventories or wait on the sidelines.
This situation is closely tied to the recovery pace of end-use textile orders. We are currently on the eve of the traditional peak season, but end demand has yet to show a clear uptick, suppressing intermediate purchasing willingness. For polyester filament producers, if price hikes cannot be passed down, their profit margins will be further compressed; if they do not raise prices, they face the risk of cost inversion. This dilemma makes producers cautious in pricing, and the market has fallen into a stalemate.
Industrial Transmission and Regional Responses
The sluggish sales ratio is not an isolated event; its impact is transmitting both upstream and downstream along the chain. Upstream suppliers of PTA and MEG will feel the weakened demand from the polyester segment, while downstream weaving enterprises may gain some bargaining power when raw material prices ease. Regionally, major polyester filament production areas such as Shengze and Changxing, as well as downstream fabric distribution centers like Keqiao, will face common pressures of insufficient orders and inventory digestion in the short term.
For weaving enterprises, persistently high raw material costs mean eroding profits, and there is a time lag in passing on product prices, leading some small and medium enterprises to consider output cuts or temporary shutdowns. If such cuts become a trend, they will further weaken demand for polyester filament, creating a negative cycle.
Market Outlook and Operational Strategies
In the short term, polyester filament prices are likely to maintain a high-level fluctuation pattern. If costs do not drop significantly, producers' willingness to hold prices remains strong; however, weak demand limits the upside potential. Whether this deadlock can be broken depends on two variables: whether polymerization costs ease, and whether end orders pick up before the peak season.
Historical experience suggests that a sales-to-output ratio persistently below 30% for several consecutive days often signals accumulating downward price pressure. If the ratio remains sluggish, producers may resort to promotions or price cuts to alleviate inventory pressure, potentially leading to a phased pullback in prices. For downstream buyers, this could be a window worth watching for restocking.
Practical Recommendations
For Purchasing Departments - Replenish on a need basis; avoid large-scale stockpiling during price stalemates to control raw material inventory costs. - Closely monitor changes in the sales ratio and polymerization costs; if the ratio remains below 30% for consecutive days, consider waiting for price corrections before purchasing.
For Foreign Trade Enterprises - Pay attention to RMB exchange rate fluctuations and lock in forward rates when taking orders to prevent exchange losses. - When signing long-term contracts with upstream suppliers, include price adjustment clauses to cope with sharp fluctuations in raw material prices.
