The August 28 sales-to-production data for polyester filament serves as a mirror reflecting the current stalemate in the chemical fiber supply chain. The average sales-to-production ratio of sample enterprises stood at 34.7%, up 5.3 percentage points from the previous trading day, but behind the numbers lies persistent downstream resistance to high prices, with inquiries sluggish and the market essentially treading water. What does this ratio level mean? It is far below the industry's recognized equilibrium line (typically a ratio above 60% is considered healthy), indicating that demand is simply not willing to absorb supply, and factory inventories are passively accumulating.
Signals Behind the Data
The 34.7% average ratio becomes more intriguing when broken down. Among sample enterprises, ratios ranged from 0% to 500%, showing extreme divergence. Some enterprises achieved a 500% ratio, suggesting that a few factories may have oversold through price cuts or special channels, but the majority hovered between 10% and 40%, and two enterprises even recorded 0%, meaning they sold almost nothing that day. This divergence is not accidental; it reflects a lack of unified confidence in the market—no trend has formed, buyers only pick bargains at low prices, and sellers stubbornly hold their cost lines without conceding.
More concerning, the 5.3-percentage-point increase in the ratio is not a sign of demand recovery, but rather the result of selective price cuts by some enterprises to stimulate sales. The persistent downstream resistance to high prices indicates that terminal orders have not improved substantially, and weaving mills are purchasing raw materials only for immediate needs, with speculative stockpiling virtually absent. This 'passive destocking' type of ratio increase is of questionable sustainability; once prices rebound, the ratio may decline again.
Malfunctioning Transmission Mechanism
The stalemate in the polyester filament market is essentially a manifestation of a malfunctioning transmission mechanism between upstream and downstream. Upstream PTA and MEG prices are supported by crude oil fluctuations, but downstream weaving mills face the dual pressure of weak terminal apparel orders and high inventory. Costs cannot be passed on, and finished goods are not selling, forcing mills to compress raw material purchases, thereby transmitting pressure back to polyester filament factories. Thus, filament factories are caught in a dilemma: if they follow raw material price increases, their sales-to-production ratio declines further; if they cut prices to promote sales, their profits are squeezed or they incur losses.
This tug-of-war is particularly pronounced in late August. The traditional 'golden September and silver October' peak season is approaching, but there are no signs of early stockpiling. Filament factories hope to leverage peak-season expectations to hold prices, while downstream players bet that factories will concede under inventory pressure. Judging from the ratio data, buyers currently have a slight upper hand, but a true inflection point is still far off. For buyers, this implies that prices may remain in a narrow range in the near term, with low probability of sharp rises or falls, but they should be wary of sudden price cuts if factory inventories exceed critical thresholds.
Chain Reactions in Industrial Clusters
The main production areas for polyester filament are concentrated in Tongxiang, Shaoxing, Xiaoshan in Zhejiang, and Shengze in Jiangsu. Inventory and operating rates in these clusters directly affect the national chemical fiber market. Persistently low sales-to-production ratios may force some factories to cut production or conduct maintenance to control inventory. If the scope of production cuts expands, it could actually support prices, but the side effect is reduced upstream raw material demand, impacting PTA and MEG trends. This chain reaction will ultimately transmit to the fabric sector: weaving mills in Shengze may adjust procurement rhythms, while traders in Keqiao will be more cautious in taking orders.
For the textile industry, the key focus now is not the small daily fluctuation in the sales-to-production ratio, but the overall profit distribution pattern across the chain. If polyester filament prices remain in a stalemate for a long time, it will squeeze upstream raw material profits and may also intensify price wars in downstream fabrics. Foreign trade enterprises should pay special attention: overseas order quotation cycles are typically long, and if raw material prices are unstable, quotation risks rise significantly.
