On September 7, the sales-to-output ratio of sampled polyester filament enterprises averaged only 23.5%, up 2.5 percentage points from the previous trading day, yet this level remains low for the year. More concerning, prices are consolidating sideways, downstream buyers show strong resistance to high prices, and market transactions are sluggish. This data sends a clear signal: the chemical fiber industry chain is in a delicate standoff, with both supply and demand waiting for the other to make a move.
Interpreting the Sales-to-Output Data
The sales-to-output ratio is a core indicator measuring the match between daily sales and production. An average of 23.5% means that for every 100 tons of polyester filament produced, only about 23.5 tons were sold that day; the rest either becomes inventory or is carried over. The distribution among sample enterprises ranges from 0% to 130%, showing clear polarization: some achieve overselling (130%), while many are stuck at 10%-25%, with some reporting zero transactions. This divergence is not accidental; it reflects differences in product mix, customer loyalty, and pricing strategies.
Compared with historical data, 23.5% sits in the mid-to-low range for the same period in recent years. Typically, early September should see stocking up for the 'golden September and silver October' season, with ratios often exceeding 50%. This year's weakness suggests that downstream weaving mills do not have full order books, and their willingness to build inventory is low. It also implies that under high raw material prices, end brands have limited acceptance of rising fabric costs, and the price transmission chain is blocked.
The Game Between Cost Support and Weak Demand
The sideways price movement of polyester filament is essentially a tug-of-war between cost support and weak demand. Upstream PTA and MEG prices have been oscillating recently, making production costs relatively rigid. Factories are reluctant to cut prices—doing so would compress profit margins and could trigger expectations of further declines, exacerbating wait-and-see sentiment. However, downstream users clearly resist current price levels, preferring to purchase on a need-to basis to avoid holding high-priced inventory during a downward cycle.
This standoff results in sluggish transactions and low sales-to-output ratios. From an industry chain perspective, polyester filament sits in the middle of the polyester chain: upstream is petrochemicals, downstream is weaving, dyeing, and ultimately apparel and home textiles. The current price stalemate essentially reflects that terminal consumption recovery is insufficient to absorb midstream and upstream costs. National Bureau of Statistics data shows that retail sales of clothing, shoes, and hats grew at a slower pace in August, and export orders face overseas destocking pressure, suggesting demand is unlikely to surge in the short term.
Chain Reactions in Industrial Clusters and Regional Differences
Major polyester filament production capacity is concentrated in Tongxiang and Xiaoshan in Zhejiang, and Shengze and Taicang in Jiangsu. Low sales-to-output ratios directly affect operating rates and inventory levels in these clusters. According to public industry data, inventory at some mainstream plants has risen to 15-20 days, above the normal level of under 10 days. Rising inventory pressure is forcing some enterprises to consider production cuts or maintenance to balance supply and demand. Weaving mills in the Shengze area report slower grey fabric movement and significantly reduced purchases of polyester filament, corroborating the sales data.
Notably, regional differences also appear in the ratio: export-oriented enterprises, with relatively stable overseas orders, have higher ratios, while domestic-oriented enterprises are more affected by weak local consumption. This structural difference implies that recovery will not be uniform; enterprises that can flexibly adjust product mix and explore new channels will emerge from the downturn faster.
Short-Term Outlook and Strategies
Looking ahead, polyester filament prices are likely to maintain narrow fluctuations, with limited upside but also limited downside. Key variables include: first, whether international oil prices and upstream raw material costs ease; if costs collapse, the price center may shift down. Second, whether the 'golden September and silver October' peak season truly materializes; if terminal orders improve significantly in late September, the sales-to-output ratio could rebound above 50%. For enterprises across the chain, it is not wise to bet blindly on market direction; instead, focus on cash flow and inventory management.
