On September 2, the polyester filament market sent a telling signal: the average sales-to-production ratio of sampled enterprises stood at only 39.1%, down 0.7 percentage points from the previous trading day. Meanwhile, most manufacturers chose to raise offers. This divergence between price hikes and sluggish transactions is not accidental—it is a typical sign of a stalemate between upstream and downstream players.
What the Data Really Shows
A ratio of 39.1% means more than 60% of daily polyester filament output failed to convert into actual sales. Enterprise-level figures varied widely, from 0% to as high as 310%, with most firms hovering between 15% and 30%. This polarization suggests that a few companies may have achieved overselling through lower prices or special channels, while the majority faced rising inventory pressure.
Price increases amid weak transactions directly reflect the tug-of-war between cost-push and soft demand. Volatility in upstream raw material prices is transmitted to the polyester filament segment, prompting manufacturers to try passing on costs, but downstream weavers are clearly reluctant to accept. Only a few users made small replenishments; most retreated to the sidelines, creating a cautious trading atmosphere.
Upstream-Downstream Transmission and Inventory Concerns
As an intermediate product, polyester filament prices directly affect the procurement costs of fabric and garment enterprises. The current low ratio indicates that inventories are accumulating at polyester plants. If this trend persists, plants may face cash flow pressure, potentially leading to production cuts or price reductions, which would create downward price risk.
For downstream buyers, the current wait-and-see approach may avoid short-term high prices, but if upstream costs remain firm, polyester filament prices may not correct significantly. Historical experience shows that a ratio below 40% often appears near turning points—either as a precursor to price softening or as a prelude to collective price support by manufacturers. The key lies in future raw material price trends and polyester plant operating adjustments.
Industrial Belt Reactions and Order Rhythm
In key consumption areas like Shengze and Changxing, weaving enterprises have recently adopted a just-in-time purchasing strategy. Terminal orders have not shown significant growth, and greige fabric inventory digestion is slow, dampening enthusiasm for raw material procurement. This cautious sentiment is transmitting upward along the supply chain, intensifying the wait-and-see atmosphere in the polyester filament market.
It is worth noting that daily sales-to-production ratios are volatile, and a single day's reading should not be over-interpreted. However, if low levels persist for several consecutive days (as seen in recent daily reports), it warrants attention. On the export front, the pace of overseas demand recovery remains uncertain, prompting exporters to maintain lean raw material inventories to hedge against exchange rate and freight fluctuations.
