The July 7 sales-to-production data hit the polyester filament market like a bucket of cold water. The average ratio among sample enterprises stood at only 42.9%, a sharp 29-percentage-point drop from the previous trading day's close. What does this figure mean? It means that for every 100 tons of polyester filament produced that day, nearly 57 tons ended up as inventory rather than being purchased downstream.
More alarmingly, this decline is the largest single-day drop since June. Within the broader polyester industrial chain, this is not an isolated market fluctuation but a collective signal from downstream weaving and texturing sectors to shift strategy.
Behind the Sales Data: Real Buying Structure
Breaking down the specific data, the distribution of sales ratios across the 23 sample enterprises was highly uneven. More than 70% of enterprises reported ratios below 45%, with the lowest at just 10% and 16%. Only a handful, such as those achieving ratios of 200% and 80%, managed to reduce inventory through price concessions.
This pattern of 'a few standouts, most sluggish' indicates that demand is not entirely absent but is extremely price-sensitive. Downstream buyers have reached a 'freezing point' in sentiment. They are no longer actively restocking as they did in June but have shifted to a wait-and-see approach, even beginning to consume existing raw material inventories.
Why Downstream Procurement Strategy Suddenly Shifted
To understand this sudden drop, we must look beyond a single day. Over the past two weeks, polyester filament prices have been pushed up by rising feedstock costs for PTA and MEG, with polyester plants maintaining a strong price-holding stance. However, orders at the downstream weaving level have not kept pace, and grey fabric inventories have been accumulating.
When upstream prices rise but downstream refuses to accept them, intermediate processors like texturing and weaving mills become squeezed. Their cash flow is tied up in high-cost raw materials, while the fabrics they produce cannot be sold at profitable prices. Under such pressure, the most rational move is to halt purchases and consume inventory. The July 7 data is a concentrated reflection of this rational choice across the industrial chain.
Impact on Polyester Plant Inventory and Price Expectations
The immediate consequence of the plunging sales ratio is a rapid buildup of finished product inventory at polyester plants. If this low sales environment persists for three to five days, inventory days could quickly rise above 15, putting significant pressure on cash flow and working capital.
Historical patterns suggest that when the average sales ratio for sample enterprises falls below 50% for three consecutive days, polyester plants are highly likely to launch a round of price promotions to boost sales volumes. This implies that polyester filament prices may face downward adjustment pressure in the coming week, especially for specifications with higher inventories and persistently low sales ratios, such as certain FDY and POY grades.
However, whether price cuts can effectively stimulate demand depends on the recovery of downstream grey fabric orders. If end-user apparel export orders do not show significant improvement by late July, even price concessions from polyester plants may only generate 'pulse-like' buying rather than sustained restocking.
Practical Insights for Industry Participants
Based on current data signals, the polyester filament market in mid-to-late July is likely to enter a 'buyer's market' phase. Upstream polyester plants are losing pricing power, while downstream users have more room for negotiation.
