The polyester filament market is experiencing a classic volume-price tug-of-war: on August 28, the average sales-to-output ratio of sample enterprises stood at only 34.7%, up 5.3 percentage points from the previous trading day, yet still at a historically low level. More notably, downstream buyers' resistance to high prices has not waned, with inquiries remaining sluggish and the market stuck in a stalemate. A ratio persistently below 40% implies that substantial inventory is accumulating at polyester plants rather than being absorbed by weaving mills.
Signals Behind the Data
The day's data distribution shows extreme divergence, with ratios ranging from 0% to 500% among sample enterprises. The coexistence of zero and very high ratios indicates not an overall weak market but structural differentiation: some differentiated products still have order support, while conventional specifications are almost ignored. Such divergence often signals a shift from broad-based rallies to product-specific trends, making specification selection more critical than market direction for buyers.
A low sales-to-output ratio is not an isolated phenomenon. It directly reflects insufficient willingness among downstream weavers to operate, as well as weak demand from terminal apparel and home textile sectors. When weaving mills themselves face high finished-goods inventories and scarce new orders, even aggressive promotions by polyester plants fail to trigger substantial restocking. Therefore, the 34.7% ratio is essentially not a price issue but a signal that the demand cycle has yet to start.
Upstream-Downstream Game and Price Expectations
Whether polyester filament prices can hold current levels depends on the balance between cost support from upstream PTA and MEG and downstream affordability. Recent fluctuations in crude oil and PX prices have squeezed polyester producers' margins to low levels, limiting room for significant price cuts. Meanwhile, downstream users are clearly waiting for lower prices, and this wait-and-see mentality prolongs the stalemate.
Historically, when the sales-to-output ratio stays below 40% for several consecutive days, polyester plants are likely to intensify promotions or adopt production cuts to support prices. If production cuts materialize, supply contraction may provide some price floor; but if demand fails to follow, cuts merely postpone inventory pressure. For market participants, the ratio trend over the next two weeks will be a key indicator for identifying a turning point. If it fails to recover above 50%, the price center may shift further downward.
Chain Reactions in Regional Industrial Clusters
As major consumption areas of polyester filament, weaving clusters such as Shengze, Changxing, and Xiaoshan see their operating rates directly constrained by raw material prices and order conditions. The current low ratio implies cautious order-taking among weavers, with operating rates likely maintained at 60-70%, and some small and medium mills even opting for staggered production or temporary shutdowns. This wait-and-see sentiment is propagating upstream, making it difficult for polyester plants to execute production plans and further aggravating inventory accumulation.
For export-oriented textile enterprises, the low ratio combined with RMB exchange rate fluctuations makes profit margins on overseas orders more uncertain. Foreign buyers continue to pressure prices, but if domestic raw material prices remain firm due to cost support, exporters' ability to pass on costs will be tested. Under such circumstances, exporters tend to prefer short and small orders to hedge against dual risks of exchange rates and raw material prices.
