Polyester Filament Yarn Sales Rate Plunges 30%: The Industrial Logic Behind Downstream Buying Sentiment Freeze

On July 7, the average sales-to-production ratio of polyester filament yarn sample enterprises stood at just 42.9%, a sharp drop of 29 percentage points from the previous trading day. This figure is not only a recent low but also means nearly 60% of production capacity failed to convert into actual sales. Downstream buying sentiment has hit a freezing point, with the overall market performing weakly and only a handful of companies barely breaking even through price concessions.

Signals Behind the Data

The distribution of sales-to-production ratios among sample enterprises was highly dispersed, ranging from 10% to 200%, but the vast majority clustered in the 20%-45% range. The extreme value of 200% merely reflects a few companies achieving short-term destocking through aggressive price cuts and does not indicate a broader demand recovery. Industry data shows that a ratio below 50% signals passive inventory accumulation; if this trend persists, the willingness of weaving mills to stock raw materials will further shrink.

This data aligns closely with the recent supply-demand dynamics of the polyester chain. Upstream PTA and MEG prices remain elevated, but downstream weaving enterprises have clearly adopted a wait-and-see attitude, buying only when prices rise. When prices are stuck in a range, the sustainability of end-user orders becomes the key variable determining procurement pace.

Upstream-Downstream Transmission: From Passive Restocking to Active Destocking

The precipitous drop in polyester filament yarn sales ratios essentially reflects a shift in the inventory cycle of the industrial chain. In the first half of 2026, supported by raw material costs and early-year restocking demand, sales ratios remained high. However, entering July, the traditional off-season effect has combined with a slowdown in pre-shipment of overseas orders, leading to a loosening of weaving mill operating rates.

For downstream users, procurement decisions have shifted from 'fear of price increases' to 'fear of price drops.' The sales ratio data indicates that even when some factories offer discounts, downstream buyers remain reluctant to increase stockpiles. Historically, such a 'buying sentiment freeze' often foreshadows short-term downward price pressure. Based on past experience, if the sales ratio remains below 50% for three consecutive trading days, polyester filament yarn factories are likely to initiate a new round of price promotions.

Regional and Product Differentiation

From a regional perspective, sales ratios varied significantly across major production areas such as Xiaoshan, Shaoxing in Zhejiang and Shengze in Jiangsu. Differentiated products like cationic yarn and high-elastic yarn maintained relatively stable sales ratios due to tight supply, while conventional grades like FDY and POY faced greater destocking pressure. This divergence suggests that within the overall downturn, supply-demand imbalances in specific subcategories may present structural opportunities.

Practical Recommendations

For Buyers - Monitor consecutive sales ratio data: If the ratio remains below 50% for the next 3-5 trading days, wait for factory price promotions before making large replenishments. Avoid heavy stockpiling during price stalemates. - Prioritize locking in differentiated products: For tight-supply items like cationic yarn and high-elastic yarn, consider stocking up at current price levels to avoid potential price surges due to supply constraints later. - Build positions in batches during discount windows: For conventional grades, adopt a small-lot, high-frequency procurement strategy to capture short-term opportunities from individual factory price concessions.

For Foreign Trade Companies - Assess the pace of overseas order pre-shipment: The July sales ratio plunge may reflect an earlier-than-usual procurement cycle by overseas clients. Review delivery schedules for existing orders to avoid passive adjustments in export quotations due to domestic raw material price drops. - Monitor the exchange rate-raw material linkage: If polyester filament yarn prices decline, export costs will fall. Consider adjusting FOB quotes to enhance competitiveness, but be vigilant against exchange rate fluctuations eroding margins. - Maintain long-term supplier relationships: During low sales periods, factories tend to prioritize stable customers. Strengthen communication with core suppliers to ensure supply priority when the peak season arrives.
