A single-day sales-to-production ratio of 39.5% for polyester filament yarn has dipped below the warning line in the five-year data series. According to public sample data from June 22, even a 1.3-percentage-point increase from the previous day still means that over 60% of the day's output remained unsold. More telling than the average is the divergence within the sample: among the 19 surveyed enterprises, two reported zero sales, and five others recorded ratios below 30%.
This is not an isolated price report but an industrial signal: downstream users are collectively altering their procurement rhythm.
The psychology behind the numbers
The 39.5% figure itself is not fatal; what matters is the behavioral logic behind it. The sample distribution shows a maximum of 120%, but most values cluster between 20% and 45%. This 'few suppliers gain volume while most stay quiet' pattern indicates that demand is not absent but is being highly concentrated on a very small number of suppliers.
What does this mean? Downstream weaving mills are no longer following the traditional rhythm of 'stock up early in the month, consume through the month.' Instead, they have shifted to a 'buy only when prices are low, and buy only from the cheapest source' sniper-style procurement. Once this model solidifies, it will directly impact the production planning and inventory management of chemical fiber plants.
From the industrial chain perspective, polyester filament yarn sits in the middle of the polyester segment, with upstream costs influenced by PTA and MEG, and downstream directly connected to weaving and apparel fabrics. Persistently low sales-to-production ratios will force plants to cut prices to clear inventory, and price cuts will further reinforce downstream wait-and-see sentiment, creating a negative cycle.
Structural issue, not seasonal fluctuation
June typically marks the start of the traditional off-season for textiles, but this year's decline in sales-to-production data exceeds seasonal norms. In the same period last year, comparable data mostly ranged between 50% and 65%, while this year on June 22, the ratio has been lingering below 40% for several consecutive days.
Two core reasons explain this. First, end-brand apparel companies have significantly delayed the release of their autumn/winter 2025 orders, making weaving mills hesitant to stock up on raw materials in advance. Second, price expectations for chemical fiber raw materials have shifted from 'bullish' to 'flat or bearish,' eliminating the speculative value of hoarding, so downstream naturally reverts to just-in-time purchasing.
This shift is structural. Over the past two years, the polyester filament yarn market experienced a cycle of 'cost-push price hikes → downstream panic buying → inventory transfer,' where plants and traders got used to forcing orders through price increases. But with terminal consumption growth slowing, brands are imposing stricter requirements on inventory turnover, directly pressuring weaving mills to avoid long-term orders and large stockpiles.
Regional and product divergence
From a regional industrial belt perspective, weaving operation rates in major polyester filament yarn consumption areas such as Shengze, Changxing, and Xiaoshan generally saw slight declines in late June, ranging from 2 to 5 percentage points. Some small weaving factories in the Jiangsu-Zhejiang region have even opted for staggered production halts to reduce electricity and labor costs.
In terms of product categories, conventional items like FDY 150D/96F and POY 150D/48F saw sluggish trading, while differentiated products such as cationic dyeable polyester filament yarn and high-elastic yarn maintained relatively stable sales. This indicates that amid overall weak demand, products with functional and differentiated attributes still retain some pricing power.
