On August 28, the average sales-to-production ratio of sampled polyester filament yarn enterprises was only 34.7%, up 5.3 percentage points from the previous trading day. This figure remains below the industry-recognized 'sluggish line'—a ratio under 50% signals rising inventory pressure. More intriguingly, despite the sequential improvement, downstream users' resistance to high prices remained unabated, inquiries were cold, and the market was stuck in a standoff. This set of contradictory signals points to a deeper structural problem in the polyester chain: the game between cost and demand has entered a 'dull knife tug-of-war' phase.
Sales Ratio Distribution: Most Enterprises Hover in the 20%-30% Range
Looking at the specific sample data, the daily sales ratio distribution shows an obvious 'long tail': most enterprises are concentrated in the 20%-30% range, with a few even hitting 0%, while the highest reaches 500%. This extreme divergence is not accidental—high-ratio enterprises likely rely on earlier locked-in orders or differentiated products, while low-ratio ones expose the homogeneous competition dilemma of conventional specifications. For buyers, this means the market is not entirely frozen but offers structural opportunities: enterprises with counter-trend high sales ratios often have stronger cost control or product innovation, and their pricing resilience is higher.
Cost Transmission Blocked: The 'Barrier Lake' Effect in the Polyester Chain
Polyester filament yarn's upstream is PTA and MEG, whose price fluctuations directly affect yarn costs. The current low sales ratio largely stems from a 'fault' between high upstream costs and downstream acceptance. Polyester plants try to pass on raw material costs through price hikes, but downstream weaving enterprises, due to insufficient orders and difficulty raising their own product prices, adopt a 'buy as needed' strategy for high-priced materials. This 'barrier lake' effect means that if upstream costs remain firm, filament yarn plants' inventory pressure will continue to accumulate, later forcing a dilemma between 'cutting prices to destock' and 'protecting prices and margins'. For downstream weaving mills, blindly restocking or completely waiting both carry risks; they should closely monitor PTA trends and major plants' maintenance schedules.
Industrial Cluster Response: From 'Grabbing Goods' to 'Selecting Goods'
Behind the sales ratio data is an obvious shift in downstream purchasing psychology. In previous raw material uptrends, weaving enterprises often panicked and hoarded with a 'buy on rising, not falling' mentality; now, facing high prices, they are more 'picky'—only inquiring about cost-effective specifications and bargaining on conventional ones. This psychology is evident in weaving clusters like Shengze and Changxing: traders generally keep inventories low, gray fabric shipment slows, further transmitting weak demand signals upstream. For filament yarn plants, the strategy of simply following cost pricing has failed; they must more precisely match downstream demand rhythms, or sales ratios will likely remain low.
Industry Adjustment Signal: From 'Scale Competition' to 'Efficiency Competition'
Long-term low sales ratios are actually pushing the industry to shift from 'scale competition' to 'efficiency competition'. The past approach of diluting costs through expansion is unsustainable when demand growth slows. Enterprises with 0% sales ratios often have single product structures and weak customer loyalty; those with 500% may achieve excess sales through futures-spot combinations, lock-in orders, or differentiated varieties. This divergence suggests that future competition in polyester filament yarn will shift from 'whether goods are available' to 'whether goods are right'. For factories, optimizing product structure and enhancing small-order quick-response capabilities may be more sustainable than continued price cuts.
