On July 7, the polyester filament yarn market saw a sudden chill in trading activity. Industry public data shows that the average sales-to-production ratio of sample enterprises was only 42.9%, a sharp drop of 29 percentage points from the previous trading day. This means more than half of the day's output failed to translate into actual sales, rapidly building inventory pressure.
Downstream buyers' purchasing sentiment hit rock bottom, with overall market performance lackluster. Among the 23 sample enterprises surveyed, only two achieved a 60% ratio, one barely balanced at 200% through discounting, while the rest languished between 10% and 45%. This extreme divergence indicates that pricing strategy has become the only lever for a few firms to gain liquidity.
Supply-Demand Imbalance: Weak Demand vs. High Capacity
The sharp decline in the polyester filament yarn sales-to-production ratio is not an isolated event but a concentrated release of long-accumulated contradictions in the industrial chain. On the supply side, domestic polyester filament yarn capacity has continued to expand since 2025, with new capacity releases not slowing despite weaker downstream demand. Industry operating rates have remained above 80%, keeping market supply at historical highs.
Demand, however, has failed to keep pace. End-use weaving enterprises face a double squeeze of insufficient orders and high finished product inventories, shifting their procurement strategy from active stockpiling to just-in-time replenishment. July is traditionally a slack season for textiles, with factors like high-temperature power cuts and volatile overseas orders further weakening weavers' willingness to operate. When upstream factories continue to produce at capacity inertia, downstream absorption capacity is clearly overstretched.
This supply-demand mismatch is directly reflected in the sales-to-production data: a 42.9% ratio means over 57% of the day's output goes into inventory. If this trend persists, social inventories of polyester filament yarn could breach warning levels within two weeks, forcing factories to ramp up production cuts or price reductions.
Failed Cost Transmission: Raw Material Price Hikes Can't Be Passed Down
Another dimension worth noting is the cost side. Recently, upstream raw material prices like PTA and MEG have risen due to crude oil fluctuations, but polyester filament yarn ex-factory prices have not followed suit. Behind this is strong downstream resistance to high-priced raw materials—fabric prices haven't risen, so fabric buyers refuse to accept higher yarn costs. The cost transmission chain is completely blocked at the weaving stage.
Looking at the July 7 data, the only enterprise achieving a 200% ratio did so through 'discounting to move goods.' While this price-for-volume tactic temporarily relieves its own inventory pressure, it further drags down overall market price expectations. If other firms follow with price cuts, they risk falling into a negative feedback loop of 'lower prices lead to more waiting, more waiting leads to lower prices.'
For polyester plants, the current challenge is not just low sales ratios but also sharply narrowing profit margins. If raw material costs continue to rise while end-product prices cannot be passed through, some high-cost capacity may face loss-making production cuts, potentially triggering a wave of passive destocking in the third quarter.
Regional and Product Differentiation: Structural Opportunities Remain
Despite the overall downturn, not all is bleak. From the sample data, some enterprises focusing on differentiated products maintained ratios around 60%, significantly higher than those for commodity grades. This indicates that demand for functional, customized polyester filament yarn still has rigid support.
Regionally, weaving start-up rates in traditional clusters like Shengze, Changxing, and Xiaoshan show clear divergence. Some export-oriented weaving enterprises, benefiting from a marginal recovery in overseas orders, show slightly higher replenishment willingness than those serving the domestic market. The improvement in foreign trade orders could be the key variable to breaking the current stalemate.
Practical Recommendations
For Buyers - The current price channel is downward. Recommend weekly batch purchasing, avoiding large one-time price locks, and waiting for factory discount windows during destocking. - Prioritize suppliers of differentiated varieties (e.g., cationic, high-elastic, functional yarns), which have stronger price resilience and faster rebound after capacity contraction. - Monitor upstream PTA and MEG inventory changes. Accelerated destocking of raw materials may signal a nearing bottom for polyester yarn prices, a good time to increase procurement.
For Foreign Trade Enterprises - Leverage current low domestic polyester yarn prices to sign forward fixed-price contracts with Southeast Asian and South Asian clients, locking in cost advantages for H2 orders. - Watch for recovery signals in overseas textile end-demand (e.g., US apparel retail inventory ratios, EU textile imports). Once demand picks up, cheap domestic inventory can translate into export profits. - Negotiate 'consignment storage' models with upstream polyester plants: factories provide storage, and enterprises pay upon actual withdrawal. This eases factory inventory pressure while reducing the buyer's capital tie-up.
Texworld believes this sharp drop in the sales-to-production ratio is an inevitable outcome of the industry's cyclical adjustment. In the short term, the market will endure a painful destocking phase; but long-term, capacity liquidation will open new growth space for firms with cost advantages and product differentiation. Buyers and foreign trade enterprises that can grasp the rhythm of current price volatility may build cost advantages during the industry trough.
