30.9% – that was the average sales-to-output ratio for polyester filament sample enterprises on August 4, down 2.7 percentage points from the previous trading day. Behind the seemingly calm chemical fiber market, this figure sends a clear signal: downstream buyers' aversion to high prices has evolved from scattered complaints into collective action, with inquiries turning cold and transactions scarce. The pricing power along the supply chain is undergoing a subtle shift.
Sales Ratio Anomaly: Demand Side Votes with Its Feet
The sales-to-output ratio is a core leading indicator of supply-demand dynamics in the chemical fiber market. A ratio of 30.9% means that less than one-third of daily output was actually sold. The sample data shows extreme divergence: some enterprises recorded a ratio of 340%, while others reported 0%. This polarization suggests the market is not uniformly weak but structurally divided – a few companies with price advantages or differentiated products still attract orders, while most producers of conventional goods face sluggish sales.
Polyester filament primarily feeds downstream weaving sectors, including water-jet looms and warp knitting machines. The persistently low sales ratio directly reflects weakened willingness among weavers to operate. High raw material costs compress processing margins, and without sufficient support from end-fabric orders, weaving mills can only reduce purchases and consume inventories to pressure upstream suppliers for concessions. This "voting with their feet" behavior is essentially a correction to the earlier rapid price hikes.
It is worth noting that the sales ratio data exhibits significant intraday volatility. A level above 30% one day can drop sharply the next, indicating highly sensitive market sentiment. Any slight change can trigger drastic adjustments in purchasing pace. For chemical fiber enterprises, this means that relying solely on price hike expectations can no longer ensure stable shipments; they must manage customer expectations more delicately.
High-Price Aversion: A Game of Profit Redistribution
The root of the current high-price aversion lies in the rapid rise of upstream raw material costs in the polyester chain, while downstream end-demand recovery has fallen short of expectations. Polyester filament prices have been passively pushed up by cost pressures, but price transmission to fabrics and garments lags significantly, squeezing the profit margins of midstream processors. When procurement cost increases outpace product price rises, downstream companies can only reduce purchase volumes or postpone restocking, thereby exerting downward pressure on the sales ratio.
According to public industry data, such situations are not unprecedented in the chemical fiber market. Similar cycles of "cost-push inflation, demand aversion, declining sales, and price correction" occur almost every year during demand season transitions. However, this time the downstream wait-and-see attitude is more resolute and longer-lasting. This may be related to the weak recovery of end-consumption or to more cautious expectations about the economic outlook.
For chemical fiber producers, high-price aversion means rising inventory risk. If the sales ratio remains below 30% for an extended period, companies will face passive stockpiling pressure and may be forced to cut prices to destock, creating a negative feedback loop of "falling prices, falling demand." Therefore, finding a balance between maintaining prices and ensuring volumes has become the most practical challenge. Some enterprises have already begun to alleviate pressure through promotional discounts or product mix adjustments.
From an industrial cluster perspective, the main polyester filament production areas are concentrated in Tongxiang, Xiaoshan, Shaoxing in Zhejiang, and Shengze in Jiangsu. The operating rates of weaving mills in these regions often serve as an early indicator of national demand changes. The current decline in the sales ratio may foreshadow an inventory adjustment cycle in these clusters, which could subsequently affect the operating loads of upstream polyester plants.
