The September 4 polyester filament sales-to-output data has made the market realize that the high-price stalemate has spread from sentiment to actual transactions. The average sales-to-output ratio of sample enterprises was only 21.0%, a sharp drop of 4.8 percentage points from the previous trading day, with many readings as low as 0% and only a few firms managing to reach 40%. Behind this figure lies a collective rejection of high-priced raw materials by downstream users, painting a vivid picture of the polyester chain caught between costs and demand.
What the Data Reveals
The sales-to-output ratio is a core indicator of daily trading activity. A 21.0% ratio means only about one-fifth of the day's output was absorbed by the market, with the rest adding to inventory pressure. The distribution among sample enterprises shows polarization: some reached 40%, while many recorded zero transactions. This divergence suggests the market is not entirely stalled but that buyers are selectively purchasing—only taking goods with clear cost-performance advantages while avoiding generally high quotes.
More notably, the ratio fell 4.8 percentage points from the previous trading day, indicating a rapid contraction in buying interest within just one day. This sudden cooling is not driven by an unexpected event but by the concentrated release of high-price resistance: as raw material prices remain elevated, downstream weaving mills see their margins squeezed to critical levels, forcing them to postpone or reduce essential purchases.
From an industry cycle perspective, September usually marks the start of the traditional peak season, but this year's "Golden September" is showing a weak start. As an intermediate product, polyester filament's sales ratio directly reflects the transmission efficiency of end-user demand from apparel and home textiles. The current figure implies that terminal demand has not recovered as strongly as expected, and upstream price increases have failed to pass down the chain effectively.
How the Price Stalemate Reshapes Upstream-Downstream Relations
The high price of polyester filament is not an isolated phenomenon. It is supported upstream by PTA and MEG costs, while downstream, weaving mills make purchasing decisions. When the sales ratio remains depressed, upstream polyester plants face mounting inventory pressure, while downstream weavers prefer to reduce operating rates rather than restock at high prices. This two-way squeeze is reshaping the bargaining landscape across the chain.
For polyester plants, a ratio below 20% is a dangerous signal—it means the price-support strategy is losing market traction. If inventories continue to climb, plants may be forced to cut prices to stimulate sales, triggering a price correction. However, raw material costs have not softened in tandem. If filament prices fall while PTA and MEG remain firm, polyester plants' profit margins will be further compressed, potentially leading to losses.
For downstream weavers, the high-price resistance is not simply about affordability but reflects expectations of a future price decline. They believe that current high prices lack demand support and will eventually ease, so they choose to wait and watch. This psychology is reflected in the low sales ratio. Once prices see a substantive correction, pent-up essential demand may be released, forming a wave of restocking.
Notably, the 0% readings in the data mostly come from small and medium-sized enterprises, while the 40% readings likely come from large firms or those with stable orders. This divergence indicates that the market is not monolithic; some companies maintain shipments through long-term contracts or differentiated products, but overall liquidity has deteriorated significantly.
Practical Implications for Buyers and Exporters
The current market is in a typical "price discovery" phase, with both sides testing each other's limits. For buyers, the worst approach is to blindly chase high prices or over-wait. Instead, they should develop flexible restocking strategies based on their order cycles. For exporters, the low sales ratio implies that overseas orders may face delivery delays or cost reassessments, so price clauses with clients should be discussed in advance.
For Buyers - Stagger purchases: avoid large one-time stockpiles; split restocking into 3-4 batches based on production plans to reduce price fluctuation risk. - Monitor inventory turning points: if polyester plant inventories rise for two consecutive weeks, the probability of price corrections increases, so consider delaying large orders. - Compare differentiated sources: some enterprises with higher sales ratios may offer better quality or prices; prioritize inquiries with them.
For Exporters - Lock in contracts: include raw material price fluctuation clauses in export contracts, specifying adjustment mechanisms to avoid unilateral cost risks. - Hedge currency and logistics: given current market volatility, use forward exchange settlements and off-peak logistics to stabilize overall costs. - Communicate with clients early: proactively explain the raw material market situation to overseas clients and seek to build profit buffers into quotes.
The polyester filament sales ratio of 21.0% is a wake-up call for the industry chain. It reminds all participants that any price increase detached from real demand is unsustainable. The coming weeks will be a critical window to test price support, and whether the sales ratio recovers will be the most intuitive indicator of market direction.
