On July 8, the polyester filament yarn market experienced a dramatic reversal. The average sales-to-production ratio of sample enterprises surged to 103.6% from 42.9% the previous trading day, a single-day increase of 60.7 percentage points. Behind this data lies a phased restocking sentiment ignited by rebounding crude oil prices and rising polyester raw material costs. However, a deep dive into individual enterprise figures—ranging from 10% to 300%—suggests this is not a signal of broad recovery, but rather a structural gamble driven by cost panic.
Cost Side: Crude Oil Ignites, Polyester Raw Materials Follow
The direct trigger for this sales pulse was rising upstream costs. International crude oil prices rebounded after hitting a low in early July, driving up prices of polyester raw materials like PX and PTA. For downstream weaving enterprises, the expectation of rising raw material costs creates a 'buy early rather than late' mentality, triggering a wave of concentrated restocking. This 'buy on rising, not on falling' psychology recurs in the polyester chain, but its sustainability depends on the actual digestion capacity of end-user orders.
Sales Divergence: Temperature Differences Between Wujiang, Changxing, and Xiaoshao
Publicly available sales data shows a wide gap among enterprises: some factories achieved ratios of 200% or even 300%, while others recorded weak performances of just 10% to 60%. This divergence is not accidental.
- Enterprises with high ratios are mostly concentrated in water-jet loom clusters like Wujiang and Changxing, which specialize in conventional polyester taffeta and pongee. These areas have fast inventory turnover and high sensitivity to raw material prices.
- Enterprises with low ratios are mostly in the Xiaoshao region, which focuses on differentiated, high-value-added fabrics for women's wear and knits. Their demand for conventional polyester filament is less elastic, and they typically maintain more cautious raw material inventory strategies.
This regional divergence implies that the current restocking is more of a short-term release of conventional products under cost expectations, rather than a substantive increase in end-user orders.
Downstream Weaving: The Divergence Between Operating Rates and Orders
Despite the impressive sales data, the fundamental picture of the weaving sector has not improved simultaneously. In early July, the comprehensive operating rate of water-jet and air-jet looms in Jiangsu and Zhejiang remained between 65% and 70%, down about 5 percentage points year-on-year. Export orders are constrained by high overseas inflation and destocking cycles, while the domestic market faces dual pressures from summer heat-related power rationing and weak end-user consumption.
The short-term jump in the sales ratio is more of an inventory transfer in the intermediate link—from finished goods inventory at polyester plants to raw material inventory at weaving mills. As long as end-user fabric orders do not show significant recovery, the sustainability of this restocking round is questionable. Historical experience suggests that such 'cost-driven' restocking cycles typically last 3 to 5 trading days, after which the sales ratio quickly falls back to the 60% to 80% range.
Implications for Polyester Plants: A Window for Inventory Reduction and Pricing Strategy
For polyester filament yarn producers, the sales explosion on July 8 provides a rare opportunity to reduce inventory. The average inventory of polyester plants had previously climbed to a high of 20 to 25 days, with some enterprises approaching the 30-day warning line. This rally allows plants to accelerate inventory clearance and alleviate cash flow pressure.
However, plants must be wary of the side effects of a 'price hike to reduce inventory' strategy. If they forcibly raise prices when downstream acceptance is limited, it may dampen restocking enthusiasm and prematurely end the rally. A more rational strategy is to maintain stable prices or make modest increases while accelerating shipments, avoiding the creation of new inventory backlogs.
Practical Recommendations for Downstream Buyers
For Weaving Enterprises - At current price levels, replenish to 15-20 days of normal usage to avoid overstocking. If polyester raw material prices continue to rise, consider extending the replenishment cycle to 25 days. - Closely monitor the trend of PTA futures. If PTA prices break through previous highs, polyester filament yarn may follow suit; if PTA retreats, suspend chasing purchases. - Prioritize purchasing conventional grades (e.g., FDY 150D/96F, POY 150D/48F). For differentiated products like micro-denier yarn or cationic yarn, maintain a demand-based purchasing rhythm to avoid secondary inventory due to product mismatch.
For Foreign Trade Enterprises - The current sales pulse has not yet translated into fabric price adjustments. Take this window to lock in prices for some conventional fabric orders with domestic suppliers to hedge against potential price increases in the next 2-4 weeks due to rising raw material costs. - For orders headed to Southeast Asian and South Asian markets, monitor RMB exchange rate fluctuations and ocean freight changes. The combined effect of rising raw material costs and exchange rates may erode profit margins by 3% to 5%. - When signing long-term contracts with polyester plants, consider including floating pricing clauses to partially transfer raw material price risk to the upstream.
Overall, the sales pulse on July 8 represents an emotional release in the polyester chain driven by cost factors, rather than a fundamental turnaround. Industry participants should remain rational and avoid linearly extrapolating short-term data. A true market inflection point will require substantive recovery in end-user orders for confirmation.
