On July 8, the polyester filament market recorded a striking data point: the average sales-to-production ratio of sample enterprises surged from 42.9% on the previous trading day to 103.6%, a single-day increase of 60.7 percentage points. While this figure appears impressive at first glance, a closer look at individual enterprise data reveals a far more complex picture.
Cost-Driven Pulse Recovery
The most direct driver of this surge came from upstream costs. The recent strength in international crude oil prices pushed up polyester raw materials including PX, PTA, and ethylene glycol. This rapid cost escalation transmitted strong price hike expectations downstream, prompting weaving mills to replenish inventories in a panic. Historically, such 'buying on rising prices' behavior is not uncommon in the polyester supply chain, but it reflects fear of price increases rather than genuine order growth.
Enterprise Divergence: A Tale of Ice and Fire
The detailed sales data released that day reveals the market's true colors. Among the 20 sample enterprises, the highest sales-to-production ratio reached 300%, while the lowest was only 10%—a 30-fold difference. Specifically, half of the enterprises achieved ratios above 100%, but a considerable number still recorded ratios below 70%, some as low as 40% or 50%. This extreme divergence means:
- Leading enterprises, leveraging scale and channel advantages, successfully captured this emotional window to destock
- Most small and medium-sized enterprises did not benefit from this wave, indicating significant transmission bottlenecks
- Enterprises with ratios above 200% may have included delivery of previous orders, not purely new demand
Transmission and Impact Along the Supply Chain
Feedback from major industrial clusters such as Shengze, Changxing, and Xiaoshan indicates increased inquiries and transaction activity around July 8. However, multiple industry insiders noted that weaving mill operating rates did not rise correspondingly, and grey fabric inventories remained high. This suggests that downstream 'yarn buying' was more about hedging against raw material price hikes than responding to new orders.
- For polyester filament plants, short-term sales improvement helps ease inventory pressure, but if terminal orders remain weak, price transmission will hit a ceiling
- For weaving mills, this replenishment increases raw material inventory costs; if prices later correct, they face inventory impairment risks
- For traders, this volatility creates arbitrage opportunities but also raises operational complexity, with quick in-and-out becoming the dominant strategy
Market Outlook and Risk Warnings
Current market sentiment is at a delicate inflection point. If crude oil continues to strengthen, the cost support logic for the polyester chain will persist, and sales ratios may remain elevated. However, caution is warranted: terminal textile and apparel export data show no significant recovery, and the domestic consumer market is in a slack season. Once cost-side momentum slows or reverses, downstream replenishment sentiment will quickly cool, and sales ratios may again fall into a slump.
Over a longer cycle, new polyester capacity continues to be added in 2026, and the overall supply-demand balance remains loose. This cost-driven pulse recovery is unlikely to change the fundamental oversupply situation. For buyers and mills, the priority should be managing inventory risk rather than chasing short-term sales figures.
