Polyester Filament Yarn Sales-to-Output Ratio Surges to 103.6%: Short-Term Resonance of Cost Transmission and Downstream Restocking

On July 8, 2026, the polyester filament yarn market witnessed a surprising surge in the sales-to-output ratio. The average ratio among sample enterprises reached 103.6%, a significant jump of 60.7 percentage points from the previous trading day. This figure indicates that shipments exceeded production within the sample pool, leading to a phased inventory drawdown.

Dual Drivers: Cost Push and Downstream Sentiment

The most direct trigger for this rapid increase in the sales-to-output ratio was the transmission of upstream costs. Crude oil prices strengthened recently, driving up the prices of polyester raw materials such as PTA and MEG. For bulk chemicals like polyester filament yarn, any fluctuation in cost quickly translates into downstream procurement decisions. Weaving mills, seeing signs of rising raw material prices, instinctively moved to secure some inventory to lock in costs, resulting in a concentrated restocking wave.

However, a closer look at the day's data reveals a significant divergence that cannot be ignored. Among the sample enterprises, the highest sales-to-output ratio reached 300%, while the lowest was only 10%. This wide gap—from 10% to 300%—indicates that the market is not experiencing a broad-based recovery but rather a 'point-like outbreak.' Some enterprises, perhaps due to more flexible pricing strategies or stronger customer relationships, captured the benefits of this restocking wave, while others saw almost no improvement in demand.

Signals Behind the Impulsive Procurement

For textile industry professionals, this type of cost-driven, rather than order-driven, surge in the sales-to-output ratio warrants caution. A true market recovery should be accompanied by a sustained increase in downstream weaving mill operating rates and a tangible rebound in end-user orders for apparel and home textiles. The current situation appears more like: upstream price hikes → midstream fear of price increases → concentrated procurement → high sales-to-output ratio. Such impulsive restocking typically lasts for a very short period, ranging from a day or two to a week at most. Once crude oil prices correct, or downstream mills realize that end-user orders have not kept pace, the restocking momentum will quickly dissipate.

Another noteworthy signal is that on July 8, the proportion of enterprises with a sales-to-output ratio exceeding 100% was not particularly high. Based on the data provided, approximately half of the enterprises had a ratio below 80%. This implies that even under the stimulus of rising costs, a significant number of enterprises failed to achieve effective destocking. This reflects the underlying reality that overall downstream demand remains weak.

Regional Responses and Divergence

The main production and sales regions for polyester filament yarn are concentrated in Zhejiang, Jiangsu, and Fujian provinces, particularly in industrial clusters like Xiaoshan, Shaoxing, Shengze, and Changle. Historically, when the sales-to-output ratio experiences such sharp fluctuations, weaving mills in these areas are often the first to react. Circular knitting mills in the Shaoxing area and water-jet loom mills in the Shengze area are typically the main forces behind restocking. However, the wide disparity in this round of data also suggests divergence among different industrial clusters: downstream mills closer to raw material sources and with lower transportation costs showed a stronger restocking willingness, while those in remote areas or smaller-scale weaving factories may have chosen to wait and see due to financial pressure or a lack of orders.

Practical Recommendations

For Buyers - Avoid blindly chasing price increases for restocking at this stage. It is recommended to limit procurement to 15-20 days of production consumption to prevent inventory devaluation if costs fall. - Monitor short-term trends in crude oil and PTA futures. If WTI crude oil shows two consecutive days of decline, consider postponing purchases and wait for prices to stabilize before entering the market. - Use sales-to-output ratio data as a negotiation tool. Enterprises with a ratio below 50% typically have a stronger desire to sell; buyers can attempt to negotiate lower prices or secure longer payment terms.

For Factories/Producers - Seize the window of high sales-to-output ratios to prioritize clearing high-inventory varieties and accelerate cash flow recovery. Avoid missing the destocking opportunity due to a reluctance to sell. - Beware of a 'false boom.' If end-user orders do not improve concurrently, this restocking wave may be followed by a longer period of demand vacuum. Consider appropriately reducing operating rates to control finished goods inventory. - Adopt a differentiated pricing strategy. For long-term customers with low sales ratios and high loyalty, offer slight discounts to secure ongoing orders; for new customers or one-time purchases, maintain market prices.
