On September 1, the polyester filament market sent a warning signal: the average sales-to-production ratio of sample enterprises dropped to 39.8%, down 43.0 percentage points from the previous trading day. Behind this figure lies the rapid cooling of a 'false fire'—the previous evening saw some manufacturers report ratios as high as 300%-400%, only to be met with price resistance and fading inquiries the next day.
Event Background
The sales-to-production ratio is a thermometer for real demand in the polyester filament market. A ratio of 39.8% means that for every 100 tons produced, less than 40 tons were absorbed downstream. Just on August 31, some manufacturers enjoyed a temporary surge with ratios of 300%-400%—often driven by concentrated restocking or speculative expectations.
After the surge, prices for most specifications were raised on September 1, but downstream resistance intensified, and inquiry sentiment weakened. The sample data showed extreme divergence: the lowest ratio was only 10%, the highest 150%, with most enterprises stuck between 15% and 40%. This pattern suggests that price hikes were not universally accepted but were individual actions by a few companies.
It is important to note that the decline in the sales-to-production ratio does not mean demand has evaporated; rather, price signals have distorted procurement timing. When manufacturers collectively raise quotes, downstream weaving mills often pause inquiries, digest inventories, and wait for prices to stabilize. In other words, the 39.8% ratio reflects a 'procurement strike' in the intermediate segment, not a collapse in final orders.
Industry Impact
For polyester filament factories, a ratio below 40% implies renewed inventory pressure. Companies that shipped heavily during the evening surge may face a vicious cycle of 'price hike—slow sales—forced markdowns' if the market rejects higher prices. Public industry data shows that capacity utilization remains high; if the ratio stays low, output cuts may reappear.
For downstream weavers and traders, resisting price hikes is not a refusal to buy but a search for better entry points. The 39.8% ratio gives them bargaining power—when factory inventories rise, quotes often soften. The risk, however, is that if upstream raw materials like PTA and MEG strengthen simultaneously, cost support may limit price cuts, turning the standoff into a 'market with prices but no deals.'
From a chain perspective, fluctuations in the sales-to-production ratio reflect profit redistribution. Early in a price hike, filament makers attempt to shift cost pressure downstream. Yet weavers themselves face weak orders and high greige fabric inventories, limiting their tolerance for raw material increases. This upstream-downstream tug-of-war will eventually resolve through adjustments in operating rates, inventory cycles, and price concessions.
Practical Recommendations
For Buyers - Adopt a wait-and-see approach in the short term, but set a price ceiling to avoid chasing rallies when the ratio recovers. - Monitor upstream PTA and MEG trends; if costs ease, consider delaying purchases. - Use the current quiet inquiry period to negotiate payment terms or small discounts with suppliers, securing some essential volumes.
For Factories - Avoid one-off price hikes; adopt a 'small steps, frequent adjustments' strategy to gauge downstream acceptance. - Strengthen monitoring of sales-to-production data; if the ratio stays below 50% for three consecutive days, trigger output cuts or product switches. - Establish price communication mechanisms with key customers to reduce information asymmetry and collective resistance.
Price disputes eventually return to supply-demand fundamentals. The 39.8% ratio reminds all market participants that without substantive demand recovery, any price hike beyond downstream capacity is merely a 'transfer' of inventory, not 'absorption.' The sales-to-production data over the coming week will speak louder than any rhetoric.
