The sales-to-output data for polyester filament yarn is sending a clear signal: downstream purchasing willingness has hit rock bottom. According to publicly available industry data from June 22, the average sales-to-output ratio of sample enterprises was only 39.5%, a marginal increase of 1.3 percentage points from the previous trading day, but still at a low point for the year. Behind these numbers lies a supply-demand stalemate that has persisted for weeks, reflecting intensifying competition throughout the chemical fiber supply chain.
What the Sales Data Really Means
A 39.5% sales-to-output ratio means that for every 100 tons of polyester filament yarn produced that day, over 60 tons went unsold and directly into inventory. The distribution among sample enterprises was highly uneven—ranging from a high of 120% to a low of 0%. This polarization suggests that not all companies face the same difficulties. Some, with price advantages or strong customer relationships, still move product, but the majority are trapped in a situation of "quoted prices but no buyers."
Importantly, the ratio improved only 1.3 percentage points from the previous day, indicating no substantive change in market sentiment. Downstream users are adopting a "buy-as-you-use" strategy, compressing replenishment cycles to the minimum, which directly suppresses spot trading volume. For chemical fiber plants, sustained low sales rates mean rapidly rising inventory days and mounting pressure on working capital.
The Logic Behind Downstream Caution
Why are downstream users so cautious? Three core reasons stand out. First, the recovery in end-use textile and apparel demand has fallen short of expectations, leaving weaving mills with insufficient orders and little incentive to stock up. Second, polyester filament yarn prices have fluctuated slightly but lack clear directional guidance, prompting buyers to wait for more definitive price cuts. Third, the persistent overhang of industry overcapacity—new production lines continue to come online despite weak demand—adds to supply-side pressure.
This negative cycle of "the more you wait, the more prices fall; the more prices fall, the more you wait" is eroding profit margins across the entire supply chain. Price movements in upstream raw materials like PTA and MEG struggle to pass through to polyester yarn, as downstream resistance to price increases is extremely high. Pricing power in the current market has effectively shifted from sellers to buyers.
Inventory Pressure Cascading Upstream
Low sales rates lead directly to inventory accumulation. According to industry estimates, social inventories of polyester filament yarn are now at elevated levels for the past year. To relieve cash flow pressure, factories have resorted to price cuts and promotional discounts, which only reinforce market wait-and-see attitudes.
From a supply chain perspective, inventory pressure is cascading upstream. Purchasing of polyester chips and PTA has also slowed, as polyester yarn factories, burdened with their own high inventories, have little incentive to replenish raw materials. This "bottom-up" negative feedback loop means the entire chemical fiber chain is in a painful destocking phase. For traders, intermediary margins are severely compressed, and the risk of holding inventory has risen sharply.
Practical Recommendations
For Buyers - This is a clear buyer's market with ample room for negotiation. Adopt a "small lot, multiple batch" procurement strategy to avoid locking in prices or volumes at once. - Closely monitor inventory levels and maintenance schedules at polyester yarn plants. If signs of concentrated production cuts emerge, consider increasing stockpiles to lock in low prices. - Prioritize suppliers with higher sales ratios and healthier cash flows to mitigate the risk of supply disruption due to financial strain.
For Foreign Trade Companies - Overseas orders are also facing weak demand. Leave sufficient flexibility in export quotations to absorb potential losses from exchange rate fluctuations or rising freight costs. - Take advantage of the current domestic price trough by negotiating long-term contracts with overseas customers to lock in raw material costs for the coming months. - Keep an eye on demand shifts in emerging markets such as Southeast Asia and South Asia, where rigid demand for polyester filament yarn still exists, offering a key avenue for export diversification.
Overall, the current adjustment in the chemical fiber market has yet to bottom out. Whether the sales-to-output ratio can recover to a healthy level above 60% will depend on actual improvements in end-use demand and the extent of factory-side production cuts. For industry participants, patience and flexibility are the most valuable assets right now—it is still too early to call a trend reversal before inventories are cleared.
