35.5% — that was the average sales-to-production ratio for polyester filament yarn sample enterprises on July 10, down 4.9 percentage points from the previous day. This means that for every 100 tons of polyester filament yarn produced that day, less than 36 tons actually reached downstream weaving mills, leaving over 64 tons as inventory.
Downstream users' concentrated replenishment lasted only a short time before they quickly retreated to a wait-and-see stance. This pulse-like buying followed by an immediate halt sends a clear signal to the entire chemical fiber supply chain: demand has not truly recovered; it was only temporarily activated by short-term price stimuli.
Background: The Behavioral Logic Behind Sales Data
The July 10 sales data comes from multiple sample enterprises, with specific values distributed as: 0%, 20%, 20%, 20%, 20%, 20%, 25%, 25%, 30%, 30%, 30%, 30%, 30%, 30%, 35%, 35%, 40%, 60%, 70%. More than half of the enterprises reported sales rates at or below 30%, with only one at 70% and one at 60%. This extremely differentiated yet uniformly low distribution indicates that the market is experiencing a widespread contraction in transactions, not just structural cold spots.
Compared to the previous trading day's data, users had replenished some inventory after concentrated buying, but the volume did not exceed routine demand. More critically, after replenishment, downstream enterprises did not continue procurement but collectively entered a 'wait-and-see mode.' In the textile industry, this behavior typically signals two things: first, terminal orders have not yet broadly improved; second, there is an expectation of further price declines.
Timing also matters. July is traditionally a low season for textiles, with weaving mill operating rates already at annual lows. Polyester filament yarn, as an intermediate raw material, directly reflects downstream mills' willingness to operate and their restocking pace. A 35.5% sales rate, combined with a sequential decline, suggests that downstream players are not only refraining from increasing purchases but are actively reducing raw material inventories.
Industry Impact: The Transmission Path of Inventory Pressure Upstream
A sustained sales-to-production ratio below 40% means that polyester filament yarn manufacturers are rapidly accumulating finished product inventories. Industry norms dictate that when the ratio stays below 50% for multiple consecutive days, mills face two direct pressures: warehouse overflow risk and declining capital turnover efficiency.
Once inventory pressure builds, it typically transmits upstream along three paths:
- First, polyester plants may adjust supply through production cuts or maintenance to stabilize price expectations.
- Second, raw materials like PTA and MEG will feel the demand slowdown, putting prices under pressure.
- Third, intermediate inventories held by traders will accelerate destocking, further compressing market liquidity.
Polyester filament yarn prices had already experienced a round of increases, but the sharp drop in sales data implies that downstream players have limited acceptance of current price levels. If terminal orders do not materially improve, the likelihood of price corrections is rising. For foreign trade enterprises, this means the window for export quotations may be narrowing, and they need to be wary of dual volatility from exchange rates and raw material prices.
