On September 3, the polyester filament market witnessed a sharp drop in trading activity: the average sales-to-production ratio of sample enterprises fell to 25.8%, down 13.3 percentage points from the previous trading day. Behind this figure lies a fierce tug-of-war between persistently high polymerization costs and growing downstream resistance. As cost-push price hikes meet weak demand, the profit distribution along the chemical fiber supply chain is undergoing subtle shifts.
Cost-Demand Mismatch
The core raw materials for polyester filament, PTA and MEG, have recently maintained firm prices, keeping polymerization costs at elevated levels. This cost pressure has forced polyester filament producers to follow up with price increases to alleviate their own margin squeeze. However, downstream weaving enterprises have shown no willingness to chase prices, instead adopting strategies of digesting inventories and purchasing on demand, resulting in sluggish overall market buying.
The cliff-like drop in the sales-to-production ratio directly reflects weak demand. Data from sample enterprises on that day showed significant divergence: some achieved ratios as high as 90% or even 70%, indicating rigid demand for certain specifications or customer groups; but many hovered at low levels of 10%-25%, with extreme cases of 0%. This pattern suggests that the market is not universally shrinking but rather experiencing intensified structural differentiation.
Upstream-Downstream Game and Transmission
Polyester filament sits in the middle of the polyester industry chain, with its price trends influenced both by upstream raw material costs and downstream demand. Currently, firm upstream costs provide bottom support for filament prices, but downstream resistance prevents smooth transmission of price increases. This tug-of-war has led to a stalemate in polyester filament prices: rising lacks transaction support, while falling is not allowed by costs.
For downstream weaving enterprises, persistently high raw material prices mean further compression of production profits. With no obvious recovery in end demand, weavers tend to maintain low raw material inventories to avoid price correction risks. This cautious sentiment in turn intensifies the production-sales pressure on filament enterprises, forcing some to make concessions or offer discounts, albeit with limited effect.
Historically, a sales-to-production ratio persistently below 30% often signals rapid inventory accumulation. If this trend continues, filament enterprises will face rising inventory pressure, and price wars may become inevitable. However, given the still-high polymerization costs, the room for substantial price cuts is equally limited, so the market is expected to maintain a narrow range consolidation in the short term.
Market Expectations and Operational Strategies
The core contradiction in the current polyester filament market lies in the mismatch between cost support and weak demand. For upstream factories, balancing price maintenance and inventory reduction is a dilemma; for downstream buyers, a balance must be struck between cost pressure and stock-up risks. Notably, the structural highlights in the production-sales data (such as a 90% ratio) suggest that differentiated products or tight specifications still have market acceptance, providing direction for enterprises to adjust product mixes.
Looking ahead, close attention should be paid to trends in polyester raw material prices and changes in downstream loom operating rates. If cost side loosens, polyester filament prices may usher in an adjustment window; conversely, if demand remains weak, some manufacturers may resort to production cuts to stabilize the market. Before the market direction becomes clear, all parties along the chain are advised to maintain flexible operations and avoid excessive speculation.
