On August 4, the average sales-to-output ratio of polyester filament sample enterprises dropped to 30.9%, down 2.7 percentage points from the previous trading day. This figure reflects strong downstream resistance to high raw material prices, sluggish market inquiries, and overall weak sales. When the ratio consistently falls below the 40% threshold, every link in the chemical fiber chain must reassess inventory and order strategies.
Supply-Demand Standoff Behind the Numbers
A 30.9% sales-to-output ratio means that for every 100 tons of polyester filament produced, only about 31 tons found buyers. The distribution among sample enterprises was highly uneven: the lowest was 0%, the highest 340%, but most companies fell in the 15%-40% range. This extreme divergence suggests that a few enterprises achieved excess sales through price cuts or special channels, while the majority faced severe inventory pressure.
Polyester filament is the core intermediate product in the polyester industry chain, connecting upstream PTA and MEG, and downstream weaving, dyeing, and apparel. The persistently low ratio directly reflects insufficient purchasing willingness among downstream weaving enterprises. High-price resistance is not an isolated phenomenon but an inevitable result of the game between cost and demand: when raw material price increases exceed what terminal orders can bear, intermediate links can only wait and see.
Sluggish and Divergent Price Transmission
Low sales ratios are usually accompanied by price declines, but this time prices have not dropped significantly. Behind this is a tug-of-war between cost support and weak demand: PTA and MEG prices remain high, squeezing polyester filament producers' profit margins and limiting room for price cuts; downstream weaving enterprises, due to insufficient terminal orders, are extremely reluctant to accept high prices. This deadlock has led to dysfunctional price transmission, with upstream increases unable to smoothly pass through, and midstream inventory pressure accumulating.
For buyers, the current market pattern means that the window for bargaining is opening, but the scope is limited. For factories, the divergent sales ratios indicate that those who can flexibly adjust product structures or even lock in profits through futures and spot combinations are gaining competitive advantages. Enterprises relying on single specifications and lacking pricing power may fall into passive inventory buildup.
Chain Reactions in Industrial Clusters
The main production areas of polyester filament are concentrated in Tongxiang and Xiaoshan in Zhejiang, as well as Shengze and Wujiang in Jiangsu. Weaving enterprises in these clusters are the primary buyers. The decline in sales ratios is directly reflected in changes in operating rates. According to industry public data, some weaving enterprises have recently begun to reduce operating loads to cope with the dual pressure of high raw material prices and insufficient orders.
This pressure is transmitting further upstream. If polyester filament sales ratios remain low, polyester plants may be forced to cut production, which would in turn affect the demand expectations for PTA and MEG. Conversely, downward expectations for raw material prices would further weaken downstream purchasing willingness, forming a negative feedback loop. For foreign trade enterprises relying on exports, exchange rate fluctuations and overseas demand uncertainty add to decision-making complexity.
Practical Recommendations
For Buyers - Purchase in batches to avoid large one-time stockpiles, leveraging bargaining space during low sales ratio periods. - Monitor PTA and MEG futures trends; if raw material prices loosen, wait for better buying opportunities. - Include price adjustment clauses in long-term contracts with suppliers to lock in some risks.
For Foreign Trade Enterprises - Reserve room in quotations for exchange rate and raw material price fluctuations to avoid profit erosion. - Develop differentiated product lines to reduce dependence on standard polyester filament specifications. - Use futures tools to hedge raw material price risks, or negotiate deferred pricing with upstream plants.
The current sales ratio data is just a snapshot of the market, but it reveals the divergence of expectations across the chain. Before costs and demand rebalance, cautious operation is more important than blindly bottom-fishing or chasing rises.
