42.3% – that was the average sales-to-output ratio for polyester filament yarn sample enterprises on July 15. Compared to the previous trading day, this figure plummeted by 24.7 percentage points, hitting a recent low. More tellingly, among the 24 sample companies surveyed, more than half recorded ratios below 40%, with the lowest hitting zero.
This is not a simple daily fluctuation. It points to a more fundamental issue: downstream weaving and texturing companies are collectively hitting the brakes, shifting their procurement logic from 'stocking up to hedge against price hikes' to 'buying only as needed, or even not buying at all.'
The Chill Behind the Sales Data
The distribution of that day's sales data reveals stark divergence. The vast majority of companies reported ratios between 20% and 40%, with only a few outliers reaching 160% or 100%, likely due to large one-off orders or promotions, and thus not representative of the broader trend. Overall, downstream users were deeply cautious, maintaining only essential purchases, resulting in sluggish market transactions.
This 'chill' did not arrive suddenly. Over the past month, polyester filament yarn prices have remained elevated, while final demand from apparel and home textile sectors has not recovered in tandem. Weaving mills are caught in a pincer movement – rising raw material costs on one side and difficulty passing on price increases to finished goods on the other – squeezing profit margins to the limit. As upstream factories hold the line on prices, downstream mills are voting with their wallets by simply not buying.
A 42.3% sales-to-output ratio means that on that day, more than half of the industry's production capacity failed to translate into actual sales. This directly leads to rapid inventory accumulation at factories. Once inventory pressure exceeds a psychological threshold, price softening or even promotional discounts become almost inevitable.
The Upstream-Downstream Game Enters a Critical Window
The core contradiction in the current polyester filament yarn market is the mismatch between upstream cost pass-through and downstream affordability.
- Cost side: PTA and MEG prices remain elevated due to volatile international oil prices and tight PX supply, providing strong cost support for polyester filament yarn factories and limiting their room to cut prices. - Demand side: July is traditionally a slow season for textiles. Combined with ongoing destocking cycles in European and American markets, incremental export orders are limited. Domestic end consumption also shows a trend of 'volume growth but value decline,' making brand owners extremely sensitive to fabric costs.
This 'squeezed from both ends' dynamic has locked the polyester filament yarn market in a stalemate. Factories are reluctant to cut prices, fearing a chain reaction – traders and weaving mills that stocked up at higher prices would face losses, potentially disrupting the entire pricing system. Yet if they don't cut prices, inventory pressure will only mount.
Historical experience suggests that when the average sales-to-output ratio of sample enterprises falls below 50% for three consecutive trading days, it often signals an approaching market inflection point. The next one to two weeks will be a critical window to observe whether factories initiate 'price cuts to destock.'
Regional and Category Transmission Effects
This decline in sales-to-output ratios does not impact all regions and product categories equally.
- Regional dimension: Weaving clusters in Jiangsu and Zhejiang, such as Shengze, Changxing, and Xiaoshan, have seen operating rates fall from June highs. Some small and medium-sized mills are voluntarily reducing output or even taking holidays, cutting raw material purchases. In contrast, production bases in Fujian and Guangdong, which focus on differentiated products like stretch fabrics and warp knits, have relatively stable orders, though demand for conventional polyester filament yarn (e.g., FDY, POY) is also weakening. - Category dimension: Differentiated varieties like fine denier and high-filament-count yarns, with higher supply concentration, maintain relatively firm prices. Commodity grades like standard 150D/48F and 75D/36F face greater downward price pressure. In export markets, demand for polyester filament yarn used in home textiles remains weak due to sluggish overseas real estate markets, but varieties used in functional fabrics for outdoor and workwear applications still have support.
Practical Recommendations
For Procurement Teams - Adopt a 'small batch, high frequency' procurement strategy during this period, avoiding large one-time stockpiling. Further market corrections are possible, but the timing and magnitude are uncertain – maintaining flexibility is more important than chasing the lowest price. - Monitor the daily change in sample enterprises' sales-to-output ratio: if it remains below 50% for three consecutive days, consider phased buying; if it suddenly rebounds above 80% with rising prices, it may signal a market bottom. - Prioritize cooperation with first-tier large factories that have ample cash flow, avoiding potential delivery or quality issues arising from capital chain strains at smaller mills.
For Foreign Trade Companies - When quoting European and American clients, adopt a 'short-term fixed price + floating clause' approach. Base the initial price on current raw material costs, but include a clause for renegotiation if raw material prices fluctuate by more than 5%, effectively hedging against the risk of raw material price declines. - Demand from Southeast Asian markets (Vietnam, Bangladesh) for Chinese polyester filament yarn continues to grow, but local weaving mills are also pressing for lower prices. Consider a combination of 'differentiated products + technical service' to enhance bargaining power, rather than competing solely on price. - Pay attention to the impact of RMB exchange rate fluctuations on export prices. The current exchange rate environment favors exports, but if raw material prices fall simultaneously, actual profit margins may be compressed. Clearly specify the settlement currency and exchange rate adjustment mechanism in contracts.
Opportunities often emerge from market pessimism. A 42.3% sales-to-output ratio is both a risk warning and a decision signal. For prepared industry practitioners, this adjustment phase may well be a window to optimize supply chains and lock in lower-cost raw materials.
