The thermometer of the polyester filament yarn market—the sales-to-output ratio—settled at a low 34.7% on August 28. Although this figure rebounded by 5.3 percentage points from the previous trading day, it still means that nearly two-thirds of production capacity failed to convert into same-day sales when compared to the industry's normal prosperity range (usually above 60%). More notably, downstream users' resistance to high raw material prices has not subsided, with inquiries remaining cold and buyers and sellers locked in a clear standoff.
Signals Behind the Data
The sales-to-output ratio distribution among sample enterprises on that day exhibited a typical 'long-tail' pattern: the vast majority of companies fell within the 10% to 40% range, with 20% and 30% being the most frequent (six and five firms respectively), while 10% and 40% each occurred three times, and two extreme values at 0% also appeared. This distribution indicates that weak demand is not an isolated phenomenon but a widespread industry condition. Particularly noteworthy is one enterprise with a ratio of 500%, which most likely stems from special orders or intra-group transfers rather than a genuine market recovery—buyers should not interpret this as a trend signal.
A persistently low sales-to-output ratio directly leads to the continued accumulation of inventories at polyester plants. Based on industry experience, when the ratio remains below 50% for several consecutive days, social inventories of polyester filament yarn typically increase by 2-3 days' worth of production each day. At current average operating rates among sample enterprises, this implies that tens of thousands of tons of invisible inventory pressure may be transmitted backward each week. For upstream suppliers of PTA and MEG, this means a potential slowdown in raw material procurement; for downstream weaving enterprises, it means that bargaining space is opening up.
Price Game and Cost Transmission
The core contradiction in the current market lies in the tug-of-war between cost support and weak demand. On one hand, high crude oil and PX prices keep cash flow costs for polyester plants elevated, leaving limited room for price cuts. On the other hand, terminal textile and apparel orders are entering the traditional transition period between low and peak seasons, with sluggish domestic recovery and external demand disrupted by shipping and exchange rate fluctuations. Weaving enterprises are hesitant to raise operating rates and maintain a just-in-time, small-order procurement strategy. This pattern of 'a cost ceiling above and a demand floor below' has locked polyester filament yarn prices in a narrow range, making rises and falls difficult.
For downstream buyers, the current low sales-to-output ratio implies weakened seller bargaining power, presenting a window to secure better purchasing conditions. However, caution is advised: if factories reduce production due to losses, supply contraction could trigger a price rebound. Therefore, it is not recommended that buyers over-suppress prices or delay purchases excessively. Instead, they should adopt a strategy of 'batch purchasing and buying on dips' aligned with their order cycles.
Regional and Chain Linkage Observations
From a regional perspective, major polyester filament yarn production capacity is concentrated in Tongxiang and Xiaoshan in Zhejiang, and Shengze in Jiangsu—clusters highly sensitive to raw material price fluctuations. The low sales-to-output data has already reflected in the grey fabric markets of these areas: some weaving enterprises have started to lower operating rates and prioritize digesting their own inventories. This conservative 'produce-to-order' stance, if sustained for more than two weeks, will gradually transmit to terminal fabric prices, forming a pattern of 'stable but weak raw materials, loosening fabrics.'
For foreign trade enterprises, two points require attention: first, the impact of RMB exchange rate fluctuations on export order profits—given the current price standoff, exchange rate changes may become the key variable determining order profitability; second, the uncertainty of international shipping lead times—if low sales-to-output ratios persist, leading to high domestic inventories, enterprises may face the dual squeeze of 'discount promotions' and 'shipping delays.' It is recommended that foreign trade enterprises incorporate exchange rate fluctuations and freight fluctuations into their quotation formulas when signing new orders and appropriately shorten settlement cycles.
