Polyester Filament Yarn Sales Rate Plunges 16 Percentage Points: Cold Thinking on Cost Transmission Failure

The polyester filament yarn market delivered an exceptionally dismal report card on June 25: the average sales-to-production ratio among sample enterprises was merely 29.5%, a precipitous drop of 16.1 percentage points from the previous trading day. This figure means that for every 100 tons of filament yarn produced that day, over 70 tons failed to convert into actual sales, with inventory pressure rapidly accumulating.

The Vicious Cycle of Cost Collapse and Demand Apathy

The direct trigger for the market's coldness was a sharp decline on the cost side. The short-term weakening of raw material prices, such as PTA and MEG, has significantly loosened cost support for polyester filament yarn. Feedback from enterprises indicates that downstream weaving companies have generally adopted a "buy on rising, not on falling" strategy—the more raw material prices fall, the more cautious they become about placing orders, waiting for even lower prices. This wait-and-see sentiment is vividly reflected in the data: among the 19 sample enterprises, 5 reported a sales ratio of 0%, with most concentrated in the 10%-40% range, and only a few reaching 60%-70%.

This situation reveals a deeper industry issue: the cost transmission mechanism in the current chemical fiber industry chain is failing. Under normal circumstances, falling raw material prices would stimulate downstream procurement, as weaving companies can lock in lower costs. However, when the decline is too rapid and severe, it triggers a "negative feedback loop"—downstream firms not only refrain from restocking but accelerate destocking, further increasing upstream inventory pressure.

Divergence Among Regions and Enterprises Reflected in Sales Data

The sales data from sample enterprises shows a clear "dumbbell-shaped" distribution: few at both ends, many in the middle. Enterprises with zero sales account for over 26%, while those with sales ratios above 60% represent only about 10%. This divergence suggests that enterprises of different scales and customer structures are facing vastly different situations. Large integrated companies, benefiting from direct supply to major clients and long-term contracts, maintain relatively stable sales ratios. In contrast, small and medium-sized polyester filament yarn factories are more exposed to the volatility risks of the spot market, becoming the group most hurt by the "wait-and-see wave."

From a regional perspective, the Jiangsu-Zhejiang area, as the main production base for polyester filament yarn and also the home to downstream weaving industrial clusters (such as Shengze, Changxing, and Xiaoshan), shows stronger transmission of sales pressure. When the sales ratio of local filament yarn factories drops below 30%, it indicates that the purchasing willingness of downstream grey fabric and fabric sectors has frozen to an ice point, making a rapid recovery in demand unlikely in the short term.

Cascading Impact on the Upstream and Downstream Industry Chain

The sharp drop in polyester filament yarn sales ratios primarily impacts inventory costs. According to current industry practices, the reasonable inventory turnover days for filament yarn factories are typically 10-15 days. A sales ratio below 30% could quickly push inventory days above 30, significantly increasing capital occupation pressure. Some enterprises may be forced to adopt measures such as production cuts or maintenance shutdowns to balance supply and demand, which will suppress demand for upstream PTA and MEG, further depressing raw material prices.

Although the downstream weaving sector temporarily enjoys the dividend of falling raw material prices, it faces the plight of insufficient orders. A low sales ratio is not an isolated event; it often interacts with weak consumption in the end-use apparel and home textile markets. Weaving companies' grey fabric inventories are also high, and even if polyester filament prices fall, it is difficult to stimulate large-scale restocking. The entire industry chain is caught in a spiral of "raw material decline → wait-and-see → weak demand → further price decline."

Practical Recommendations

For Buyers - Adopt a "small batch, frequent order" procurement strategy to avoid the risk of price declines from large one-time stockpiles. - Monitor PTA futures trends and polyester plant operating rates. If PTA prices stabilize and factories begin to cut production, moderately increase procurement to lock in periodic lows. - Negotiate more flexible payment and delivery terms with suppliers to transfer some inventory pressure upstream while retaining a buffer for price adjustments.

For Foreign Trade Companies - Overseas customers are highly price-sensitive. Leverage the current cost advantage to proactively adjust quotes and secure new orders. Include price protection clauses in contracts to avoid losses from subsequent raw material rebounds. - Strengthen efforts to explore markets in Southeast Asia and South Asia, where the textile industry is expanding and has sustained demand for polyester filament yarn and downstream fabrics. - Monitor exchange rate fluctuations and ocean freight changes. When costs decline, ensure export quotes remain competitive by integrating logistics and settlement costs.
