On August 28, the average sales-to-output ratio of polyester filament sample enterprises was only 34.7%, up 5.3 percentage points from the previous trading day. What does this number mean? Simply put, for every 100 tons of polyester filament produced that day, fewer than 35 tons were purchased by downstream buyers. The market did not lack transactions entirely; rather, purchasing willingness was suppressed by high prices.
Low Sales Ratio: Not Disappearing Demand but Price Mismatch
A 34.7% sales-to-output ratio is considered a cold level in the polyester filament industry. Looking at the distribution among sample enterprises, ratios ranged from 0% to 500%, with extreme values reflecting divergent pricing strategies. Some companies offered discounts and achieved ratios as high as 500%, while most held firm on prices, with ratios hovering between 10% and 30%. This divergence reveals a core contradiction: downstream users' resistance to high prices remains unabated, inquiries are cold, and the market is at a standstill.
From an industry chain perspective, low sales ratios do not signal an overall collapse in demand. Weaving enterprises still operate at reasonable capacity utilization rates, but their raw material inventory strategies have turned cautious. When polyester filament prices are at elevated levels, downstream buyers prefer to reduce inventory days rather than pay high prices. This is essentially a game of price expectations between upstream and downstream—upstream is constrained by PTA and MEG costs with limited room to cut prices, while downstream is extremely sensitive to raw material price increases due to thin margins on end orders.
Cost-Demand Tug-of-War: Industrial Logic Behind Price Standoff
The root of the polyester filament price standoff lies in the dual squeeze from cost and demand. Upstream in the polyester chain, PTA and MEG prices remain high due to international oil price fluctuations and supply-demand dynamics, providing strong cost support for polyester filament. However, downstream weaving and garment industries are in a transitional period between traditional peak and off-seasons, with no explosive growth in end orders, leaving polyester filament in an awkward position—unable to rise or fall.
For polyester plants, discounting means compressed profits, potentially even below cash costs, while holding prices risks inventory buildup. The August 28 data shows that most enterprises chose to wait, preferring lower sales ratios over price cuts, reflecting industry expectations of demand recovery in the future. Notably, persistently low sales ratios will force production cuts and maintenance, creating a new balance on the supply side.
Market Transmission and Regional Industrial Cluster Reactions
Changes in polyester filament sales ratios are now transmitting downstream. Procurement managers in weaving clusters such as Shengze, Changxing, and Keqiao generally report a noticeable slowdown in raw material purchasing, with most orders being urgent replenishment only. Some weaving enterprises are adjusting product mixes, increasing the proportion of differentiated products to avoid price wars on standard specifications. In the short term, this adjustment may intensify sales pressure for regular polyester filament varieties, but in the long run, it helps drive product upgrades across the industry.
For foreign trade enterprises, RMB exchange rate fluctuations and rising shipping costs add further uncertainty to order taking. During the price standoff, quotation cycles for foreign orders lengthen as both buyers and sellers await clearer price signals.
Practical Recommendations
For Buyers - Monitor sales ratio trends; if it remains below 40% for several days, anticipate upstream discount promotions and consider phased purchasing. - Sign short-term floating-price contracts with suppliers to lock in part of raw material needs and hedge against sudden price surges. - Optimize raw material inventory management and use futures tools to hedge price volatility, especially for standard specifications.
For Foreign Trade Enterprises - Include raw material price adjustment clauses in quotations to incorporate polyester filament price fluctuations into cost calculations and avoid losses on long-term orders. - Prioritize short-term and quick-turn orders to reduce exposure to raw material price swings, while monitoring exchange rates and locking forward settlements. - Expand exports of differentiated products such as recycled polyester filament and functional fabrics to reduce price competition pressure on standard items.
Price standstills never last forever. When sales ratios remain low for consecutive days, inventory pressure on polyester plants will force concessions. For every link in the chain, what is needed now is sensitivity to data and respect for cycles.
