The polyester filament market is experiencing a delicate game where price hikes coexist with sluggish trading. On September 2, industry data showed the average sales-to-output ratio of sample enterprises fell to 39.1%, down 0.7 percentage points from the previous day, while most manufacturers raised quotations. This contrast signals more than just cost support; it reflects weak downstream demand and fragile market confidence. When the ratio drops below 40%, the transmission logic of the chemical fiber supply chain is shifting subtly.
Signals Behind the Data
A sales-to-output ratio of 39.1% is a warning sign. In the chemical fiber industry, a ratio below 50% typically indicates rising inventory pressure, and 39.1% is near yearly lows. The distribution of daily sales ratios among sample enterprises shows extreme divergence: the highest reached 310%, the lowest was 0%, with most firms concentrated in the 10%-40% range. This polarization suggests the market is not universally shrinking but that demand is highly concentrated among a few suppliers with price advantages or strong customer loyalty, leaving others facing order attrition.
The coexistence of price hikes and declining sales reflects dual pressures from costs and demand. Upstream raw material price fluctuations push filament producers to pass on costs downstream, but weak recovery in textile and apparel consumption dampens weaving enterprises' purchasing willingness, undermining price hike support. Small replenishments by some users are more driven by rigid demand than proactive stockpiling, confirming strong wait-and-see sentiment. For buyers, this means the current moment is not ideal for locking in long-term contracts; inflated prices warrant caution.
Transmission and Industrial Belt Reactions
Polyester filament price trends directly impact weaving costs in major industrial belts like Shengze and Keqiao. A falling sales-to-output ratio will force upstream producers to adjust strategies: if inventory pressure accumulates, price cuts or promotions may follow. Historical experience indicates that when the ratio stays below 40% for consecutive days, filament prices often soften within one to two weeks. Thus, the current price hike appears more like a tentative probe, with actual transaction prices varying widely, reflecting a shift in pricing power from sellers to buyers.
For downstream weaving enterprises, raw material costs account for 60%-70% of total production costs, making filament price fluctuations directly impact their margins. Under current wait-and-see sentiment, weavers maintain low raw material inventories and adopt a need-based purchasing strategy. This short-order, small-lot model reduces inventory risk but weakens bargaining power with upstream suppliers. The profit distribution along the supply chain is tilting, and whoever breaks the deadlock first will determine the next phase's direction.
Price Expectations and Operational Strategies
Given the supply-demand signals, the polyester filament market is likely to maintain a range-bound pattern in the short term. If costs remain high, producers' intention to support prices persists; but without substantial demand improvement, the sales ratio cannot recover effectively, limiting upside. In the medium term, attention should be paid to actual order fulfillment during the traditional 'golden September and silver October' peak season and marginal changes in terminal apparel retail data. If peak-season demand disappoints, a destocking price correction may occur.
