On August 28, the average sales-to-production ratio of sampled polyester filament enterprises stood at 34.7%, up 5.3 percentage points from the previous trading day. Yet this figure remains below the industry warning line, implying that over 60% of output has not been converted into actual sales. Downstream users' resistance to high-priced raw materials has not subsided, inquiries remain sluggish, and the stalemate continues.
Signals Behind the Data
A single-day ratio may seem ordinary, but its implications are significant against a backdrop of multi-day trends. Public sample data show extreme divergence among enterprises, with ratios ranging from 0% to 500%. The 500% outlier suggests some firms achieved overselling through price concessions or special orders, while those at 0% are completely stuck in a market with no buyers. This polarization indicates not a full-scale contraction but a structural adjustment—enterprises with cost advantages or strong customer loyalty can still ship goods, while others are forced to accumulate inventory.
Notably, although the ratio rose by 5.3 percentage points from the previous day, the absolute level remains low. This suggests the rebound is technical rather than a genuine recovery in demand. For weaving mills, the pace of raw material procurement directly affects capital occupation and profit margins. Without clear improvement in end orders, replenishing only as needed remains the mainstream strategy.
Cost and Demand Squeeze
The price standoff in polyester filament is rooted in the mismatch between upstream costs and downstream affordability. Raw material costs in the polyester chain are supported by international oil price fluctuations, but downstream textile enterprises face dual pressures of weak consumer demand and high inventory. When raw material prices exceed the psychological threshold of weaving mills, reducing production or halting operations to wait and see is more rational than passively accepting higher costs.
This impasse transmits in both directions along the supply chain. If polyester plants maintain high operating rates, inventory pressure will accumulate daily, eventually forcing them to cut prices to promote sales. Conversely, if they proactively reduce output, raw material prices may loosen, exacerbating pessimistic expectations. Historical experience suggests that when the sales-to-production ratio stays below 40% for consecutive days, a price adjustment window often approaches, but the direction depends on the cash flow resilience of polyester plants.
For buyers, the current juncture offers both bargain-hunting opportunities and risks of further declines. The key lies in judging the true recovery pace of downstream demand—if orders for the traditional peak season materialize as scheduled, current prices may already be a cyclical low; otherwise, more downside may remain.
Ripple Effects Across Industrial Clusters
Polyester filament is mainly consumed in textile clusters in Zhejiang and Jiangsu provinces. The low sales-to-production ratio directly reflects on the operating rates of weaving mills in these regions. Some small and medium-sized factories have begun to shorten working hours proactively to control finished goods inventory. This wait-and-see sentiment is transmitting upstream, forming a negative feedback loop: weak terminal demand, lower weaving loads, reduced raw material procurement, and rising polyester inventory.
Notably, strategies diverge among enterprises of different sizes. Large polyester plants, leveraging capital and channel advantages, tend to maintain price stability to protect market order, while smaller ones are more flexible, possibly using hidden discounts or extended credit terms to secure orders. This divergence will intensify market competition and may accelerate industry consolidation.
For foreign trade firms, exchange rate fluctuations and international shipping cost changes are adding to domestic raw material price pressures. If the RMB appreciates or freight rates rise, the competitiveness of exported finished goods will weaken even if domestic polyester filament prices remain unchanged. Therefore, export quotations need to tie raw material and logistics costs more closely to avoid profit erosion from both sides.
Practical Recommendations
For Buyers - Monitor polyester plants' inventory days and maintenance schedules; higher inventories mean larger bargaining room. - Adopt phased procurement to avoid over-committing quantities and maintain flexibility against price swings. - Negotiate credit terms or consignment storage with suppliers to reduce capital occupation risks.
For Foreign Trade Firms - Include raw material price adjustment clauses in quotations to reduce cost uncertainty for long-term orders. - Prioritize suppliers with stable sales-to-production ratios and sound inventory management to ensure delivery reliability. - Use currency hedging tools to manage RMB volatility and monitor freight trends to adjust FOB/CIF terms timely.
The stalemate in the polyester filament market will not last forever, but a breakthrough requires clear signals—either a substantive recovery in demand or proactive supply adjustments. Until then, all links in the chain must seek balance amid caution.
