Wangjiangjing Polyester Filament Market Stagnation: Signals of Downward Adjustment and Procurement Window

The polyester filament yarn quotations at the Wangjiangjing market in Zhejiang showed an unusual 'broad stalemate' on June 28—over 30 specifications of FDY, POY, and DTY products remained unchanged from three days earlier. But beneath the calm surface, two subtle cracks have emerged.

Price Signals: Structural Divergence Amid Broad Stability

According to China Customs and industry public data, within this quotation cycle, two FDY semi-dull specifications—100D/72F and 150D/36F—each dropped by 100 yuan per ton, from 9,100 to 9,000 yuan/ton and from 8,700 to 8,600 yuan/ton, respectively. All other mainstream specifications, such as 50D/24F, 68D/24F, and 75D/36F, held at June 25 levels. POY and DTY series remained unchanged across the board.

This pattern of 'most unchanged, a few loosening' sends two key signals: first, upstream polyester factories are taking a wait-and-see approach to large-scale price adjustments under the dual pressure of costs and inventory; second, medium-denier specifications like 100D and 150D are the first to feel the pinch, reflecting weakening order intake in downstream water-jet and warp-knitting markets.

Industry Impact: Supply-Demand Rebalancing from Wangjiangjing to Jiangsu-Zhejiang

As a major distribution hub for polyester filament yarn in the Yangtze River Delta, Wangjiangjing's quotations often lead downstream fabric markets like Shengze and Keqiao by one to two weeks. The core contradiction behind the current price stalemate lies in the persistent weakness of upstream PTA and MEG prices. While polyester factories' cash flow has slightly improved, the seasonal lull in end-user orders is accelerating transmission.

From a product structure perspective, FDY 75D/144F is selling reasonably well, indicating resilience in demand for lightweight fabrics. However, buying power for DTY 150D/144F is weak, suggesting that destocking pressure in the draw-texturing segment is squeezing upstream. This divergence between 'fine denier stable, coarse denier weak' means procurement timing must be judged by category.

Outlook: Creeping Decline More Likely Than Sharp Drop

Combining upstream polyester feedstock trends and downstream operating rates, industry public data suggests that the probability of a 'creeping decline' in polyester yarn prices over the next two weeks is far higher than a 'sharp drop.' Three reasons support this view:
- Polyester factories currently hold neutral inventory levels, with no urgent cash-flow pressure to slash prices.
- Downstream weaving mill operating rates have fallen from 72% in early June to around 68%, but there is no panic shutdown.
- Some traders still hold high-priced inventory from earlier periods; aggressive price cuts would trigger hedging unwinding.

For weaving and trading companies, this is a classic 'bargaining window'—raw material prices have not yet clearly declined, but directional expectations have already formed.

Practical Recommendations

For Procurement Managers - For specifications like FDY 100D/72F and 150D/36F that have already softened, adopt a strategy of 'small batches, low base bids' to test factories' minimum acceptable prices. - For firm-priced specifications like FDY 50D/24F and POY 75D/96F, maintain only one week's inventory and avoid chasing price increases. - Monitor polyester factories' weekend settlement prices and weekly operating rate reports from major Jiangsu-Zhejiang weaving clusters as reference indicators for replenishment rhythm.

For Foreign Trade Companies - With current polyester yarn prices at the mid-range of the year, if you hold orders for September-October delivery, reserve a 5%-8% downward adjustment space in forward price locks. - Inquiries from Southeast Asian and South Asian clients for FDY 150D/96F and DTY 150D/48F are increasing, but actual transactions are highly price-sensitive. Quote with a 'floating pricing' mechanism. - Watch the compounded effect of RMB exchange rate and ocean freight fluctuations on export costs, and avoid signing fixed-price long-term contracts during the raw material price downtrend.
