On July 2, the average sales-to-production ratio of polyester filament yarn sample enterprises dropped to 31.7%, a further decline of 4.1 percentage points from the previous day. Behind this figure lies a sharp clash between high cash flow and downstream resistance: market transactions are sluggish, and actual deals are scarce. The chemical fiber chain stands at a subtle inflection point—when cost pressures can no longer be passed downstream, pricing power is quietly shifting from mills to buyers.
Signals from the Sales Data
Looking at the public data, out of 25 sample enterprises, two reported a ratio of 0%, five were below 20%, and the highest was only 70%. This distribution pattern—low volume, fragmented, without concentrated releases—reflects that downstream weaving mills have frozen their purchasing intentions. Typically, a ratio of 60%-80% is considered normal; below 50% signals rapid inventory buildup. The 31.7% figure, lingering at low levels for multiple days, indicates a trend rather than a one-day fluctuation.
The sustained high cash flow is the root of the current contradiction. With relatively stable raw material prices for PTA and MEG, polyester filament yarn mills have enjoyed generous margins from low-cost feedstock inventories. However, downstream users are unwilling to pay for these margins. Weaving mills face weak order visibility, and end-use demand from apparel and home textiles remains sluggish, limiting their ability to accept high-priced raw materials.
Disruption and Reshaping of the Supply Chain
The traditional pricing logic in the chemical fiber chain is "cost-plus": price fluctuations from PX to PTA to polyester filament yarn are transmitted stepwise downstream through inventory and capacity adjustments. But the current scenario is breaking this linear chain. When mills try to maintain high cash flow, downstream players "vote with their feet"—reducing operating rates, consuming existing inventories, and delaying purchases.
The feedback to upstream is direct and brutal: persistently low sales ratios will force mills to cut production or lower prices. Historical experience shows that when the ratio stays below 40% for a week, price promotions or voluntary price cuts typically occur within two weeks. Once a price-cut expectation forms, downstream buyers will wait further, creating a negative spiral of "more decline, less buying."
For industrial clusters like Shengze, Changxing, and Xiaoshan, this signal is critical. Weaving mills in these regions are currently caught between insufficient orders and high raw material costs. If polyester filament yarn prices do not see a meaningful correction, weaving operating rates could drop from the current ~70% to below 60%, impacting downstream processes like greige fabric and dyeing.
Practical Recommendations
For Buyers - Stay on the sidelines in the short term; current high-cash-flow prices lack demand support, with a 5%-8% downside likely in the coming week. Avoid chasing high prices for stockpiling. - Monitor mills' inventory days and production cut announcements—when average inventory exceeds 15 days, a price-cut window will open. - Use the current sluggish market to renegotiate long-term agreements with suppliers, seeking more flexible settlement terms or price adjustment mechanisms.
For Mills - Proactively reduce operating loads to prevent passive inventory buildup; a 5%-10% cut can ease sales pressure and signal price adjustments. - Adjust product mix toward differentiated, high-value-added varieties (e.g., cationic, high-elastic yarn) to reduce competition in commodity grades. - Strengthen direct supply partnerships with key downstream clients through volume-locked or tolling arrangements to stabilize cash flow.
The core contradiction in today's chemical fiber market has shifted from upstream cost games to downstream demand pricing. The 31.7% ratio is not an isolated data point—it is a microcosm of the entire chain's transition from a seller's to a buyer's market. In the next two weeks, the direction of polyester filament yarn prices will hinge on whether mills can find a balance between production cuts and price reductions. For all participants, this adjustment is both a challenge and an opportunity to reassess supply chain resilience.
