On September 4, the polyester filament market hit a freezing point. Industry data shows that the average sales-to-production ratio of sample enterprises fell to 21.0%, down 4.8 percentage points from the previous trading day. Behind this figure lies a collective rejection of high prices by downstream users, as buying activity shrank to just-in-time needs, pushing the market into a classic volume-price stalemate.
Demand Truth Behind the Sales Data
Looking at the day's enterprise-level data, performance varied significantly, with the lowest ratio at 0% and the highest at 40%, while most enterprises hovered between 10% and 20%. This means that more than half of the sample enterprises sold less than one-fifth of their output, and some even recorded zero transactions. The continuous decline in the sales-to-production ratio is not accidental but a concentrated release of market caution over the past week. In previous trading days, polyester filament prices remained high due to cost support, but downstream weaving enterprises showed little willingness to stock up, and price increases failed to transmit effectively to the fabric segment.
This pattern of "upstream rising, downstream waiting" reflects a structural contradiction in profit distribution along the supply chain. Polyester plants are under pressure on the raw material side and attempt to maintain processing margins by supporting prices, while weaving enterprises, burdened by insufficient orders and high finished-goods inventories, have a very limited tolerance for high-priced raw materials. The sales-to-production ratio thus becomes a key indicator of the intensity of upstream-downstream bargaining—when the figure stays below 30% for consecutive days, it often signals accumulating pressure for price adjustments.
Cost Pass-Through Failure and Industrial Cluster Reactions
The core cost components of polyester filament are PTA and MEG. Recent fluctuations in international oil prices have driven naphtha prices, and spot PTA prices have followed suit, but the transmission to the polyester filament stage has been notably attenuated. The logic of cost-push inflation often fails when demand is weak—factories try to pass on cost pressure downstream but meet rigid resistance from weaving enterprises. This failure is particularly evident in traditional textile clusters. In Shengze and Changxing, water-jet loom operating rates remain around 70%, but new orders are mostly samples and small lots, with bulk purchases rare. Traders in the Keqiao fabric market are also waiting on the sidelines for clearer price signals.
Notably, the structural divergence in sales-to-production ratios also reflects strategic differences among enterprises. Some large integrated polyester plants, leveraging cost advantages, still maintain relatively higher sales ratios, while small and medium factories face greater inventory pressure. This divergence may accelerate industry consolidation—in a low-profit cycle, capacity lacking cost competitiveness will shrink first.
Short-Term Outlook and Operational Strategies
Looking ahead, polyester filament prices are likely to fluctuate within a range. On one hand, raw material costs provide some support, and factories are inclined to hold prices firm. On the other hand, terminal demand is in a transitional period before the traditional peak season, with limited order growth. It is unlikely that the sales-to-production ratio will recover significantly until inventory pressure reaches a critical point. The real turning point may emerge when downstream weaving enterprises begin centralized restocking—which typically requires either a certain price correction or a substantial improvement in terminal orders.
For market participants, the current phase is not about prediction but risk management. A just-in-time purchasing strategy avoids high-price risks but may miss opportunities for low-price restocking. Therefore, a flexible, phased procurement strategy may be better than a single one-time decision.
For Buyers - Maintain just-in-time purchasing rhythm, avoid chasing high prices, and consider building positions in 2-3 batches to smooth costs - Closely monitor PTA and crude oil futures trends; if raw material prices correct significantly, increase purchase volumes moderately - Negotiate delayed delivery or post-pricing models with upstream factories to hedge against price volatility
For Exporters - Incorporate exchange rate fluctuation margins into export quotations and lock in forward settlement ratios - Pay attention to ocean freight changes and shipment delay risks, and plan delivery schedules accordingly - Utilize logistics and financial services on platforms like Huaxianbang to optimize capital turnover efficiency
Overall, the current stalemate in the polyester filament market is a result of intertwined industry cycles and cost bargaining. All participants need to find certainty amid uncertainty—through refined inventory management and flexible pricing strategies to protect profit margins.
