On July 15, 2026, the average sales rate of polyester filament yarn sample enterprises plummeted to 42.3%, dropping 24.7 percentage points from the previous trading day. This figure means that less than half of the products were absorbed by the market, with downstream procurement almost at a standstill. Against the backdrop of the traditional off-season combined with continuous capacity release, the chemical fiber industry is facing a concentrated outbreak of supply-demand contradictions.
Worsening Supply-Demand Imbalance
The plunge in the sales rate is not an isolated incident. According to industry public data, the sales rate distribution among sample enterprises on that day was extremely uneven: the highest reached 160%, while the lowest was 0%. This extreme polarization suggests that the market has not collapsed entirely but is suffering from severe structural divergence—some enterprises still maintain high shipments through special channels or product advantages, but the vast majority of factories have fallen into sluggish sales.
Polyester filament yarn, as the core variety in the chemical fiber industry chain, its sales performance directly reflects the willingness of downstream weaving enterprises to start production. July is usually the off-season for textiles, but a single-day drop of 24.7 percentage points far exceeds seasonal fluctuations. Behind this is the long-term accumulation of overcapacity: over the past two years, new domestic polyester filament yarn capacity has been continuously released, while terminal demand growth for garments and home textiles has significantly slowed, leading to a widening supply-demand gap.
The description of downstream users adopting a wait-and-see attitude and maintaining only rigid demand purchases actually reveals a deeper crisis of confidence. When buyers generally expect prices to fall further, any inventory replenishment becomes uneconomical. This expectation becomes self-fulfilling—the more they wait, the more passive manufacturers become in cutting prices, further reinforcing bearish sentiment.
Price Transmission and Inventory Pressure
The direct consequence of the sales rate plunge is rapid inventory accumulation. The polyester filament yarn industry typically considers a sales rate of 100% as the inventory balance line; anything below means increasing inventories. A 42.3% sales rate implies that inventories increased by nearly 60% on that day. If this trend continues, factories will face the risk of overflowing warehouses within weeks.
Inventory pressure is now transmitting upstream along the industry chain. Polyester chips, as the direct raw material for polyester filament yarn, are seeing synchronized demand contraction. The upstream of polyester chips—PTA (Purified Terephthalic Acid) and MEG (Monoethylene Glycol)—are also under pressure. Previously affected by international oil price fluctuations, PTA costs were already at relatively high levels. Now, the collapse in demand has made cost support fragile.
More notably, the individual enterprise achieving a 160% sales rate in the divergence often indicates low-price dumping or concentrated large orders. However, this isolated case cannot mask the overall industry weakness. Judging from the data distribution, most enterprises' sales rates are concentrated in the 20%-40% range, indicating severe market liquidity shortage. This scenario of 'a few celebrating while most suffer in winter' may accelerate industry consolidation.
Impact on Buyers and Foreign Trade
For downstream weaving enterprises, the current market offers a rare bargaining window. However, it is important to note that low prices are not the only consideration—there is a risk that suppliers under financial strain may lower quality standards. It is recommended that buyers strengthen inspections on indicators such as gray fabric and color fastness while negotiating prices.
Foreign trade enterprises face a more complex situation: overseas orders are already affected by geopolitical tensions and exchange rate fluctuations, and the sharp volatility in domestic raw material prices further complicates quotation. In the short term, export contracts can include raw material price fluctuation clauses to transfer some risk to customers. In the medium to long term, optimizing supply chain layout and diversifying procurement sources is advisable.
Practical Recommendations
For Buyers - Leverage the current buyer's market to sign short-term price lock agreements with suppliers, but include quality breach clauses. - Monitor inventory levels: prioritize purchasing from suppliers with higher inventory pressure, as they have greater bargaining room. - Establish a dynamic price comparison mechanism: track daily sales rate and price changes to capture urgent discount opportunities.
For Foreign Trade Enterprises - Include raw material price linkage clauses in export contracts, agreeing to renegotiate unit prices when domestic polyester filament yarn prices fluctuate by more than 5%. - Diversify procurement channels: besides mainstream domestic suppliers, consider alternative producing regions such as Southeast Asia and India as backups. - Use futures tools: hedge via PTA or polyester staple fiber futures to lock in long-term procurement costs.
This plunge in the chemical fiber industry's sales rate, on the surface a short-term demand fluctuation, is actually the inevitable result of a mismatch between the capacity cycle and the demand cycle. For practitioners, pessimists see inventory pressure, while optimists see an opportunity to eliminate outdated capacity. Before the industry completes its shakeout, flexible response and proactive risk avoidance are keys to survival.
