Subtle Signals in Wangjiangjing Polyester Filament Market: Volume and Price Stabilize as Polyester Cost Support Firms Up

On July 9, the Wangjiangjing polyester filament market reported a set of intriguing price data: dozens of mainstream specifications across FDY, POY, and DTY categories remained unchanged from July 7, regardless of the producer—whether Rongsheng, Tongkun, or Xinfengming. Yet market feedback indicated increased sales volume and narrowing discounts. This divergence between 'rising volume and flat prices' often signals a silent shift in supply-demand dynamics.

Structural Differences Behind Price Stagnation

Looking at specific quotes, FDY semi-dull 75D/36F traded stably at 8600-8700 yuan/ton, POY 150D/48F at 7950 yuan/ton, and DTY 150D/48F in the 9100-9200 yuan/ton range. Notably, FDY 50D/24F was quoted at 9200 yuan/ton by most mills, with only Shenghong Chemical Fiber at 9300 yuan/ton, indicating a premium for high-end products.

Sales performance varied by product type. FDY 75D/144F, a fine-denier multi-filament yarn, sold well, linked to recovering demand for home textiles and imitation silk fabrics. In contrast, DTY 150D/144F saw weak buying interest, suggesting downstream texturing mills remain cautious about stocking standard specifications. This structural divergence means not all polyester yarns have equal pricing power; buyers must differentiate by end-use.

Upstream Cost Base Shows 'Tail-Up' Signs

Market data indicates that upstream polyester feedstocks PTA and MEG have recently shown a fluctuating upward trend. Although feedstock prices did not spike on July 9, the gradual rise in cost centers is compressing polyester mills' processing margins. Historically, when feedstock strengthens for several consecutive days, polyester yarn prices tend to follow with a 1-2 week lag.

Wangjiangjing, as a key polyester yarn distribution hub in Jiangsu-Zhejiang, directly influences weaving clusters like Shengze and Keqiao. Current FDY and POY quotes are near two-month lows, and mills show strong willingness to support prices. Once downstream weaving capacity utilization picks up—currently around 75% for water-jet looms in Jiangsu-Zhejiang—polyester yarn inventory will accelerate destocking, releasing price elasticity.

Outlook: Gradual Rise, Not a Spike

Overall, this polyester yarn cycle is likely to follow a 'small-step, slow-rise' path. Three reasons:
- Upstream feedstock gains have not yet formed a trend breakthrough; cost support is more 'floor' than 'lift'.
- While export orders are recovering, EU and US retail inventories remain high, and brand orders are conservative.
- Polyester mills' own inventory levels are manageable, with no pressure for aggressive price-cutting.

Over the next two weeks, the most liquid specifications—FDY 75D/36F and POY 150D/48F—are expected to lead with a 50-100 yuan/ton increase. DTY series, with larger texturing margins, may see more limited follow-through.

Practical Recommendations

For Buyers - With current prices near cyclical lows, consider increasing stock for well-selling items like FDY 75D/144F and POY 100D/96F to lock in costs. - Maintain just-in-time purchasing for slow-moving items like DTY 150D/144F; avoid chasing price increases. - Monitor spot PTA prices and PX export quotes. If PX rises for three consecutive days, trigger early order placement.

For Foreign Trade Companies - Include polyester yarn price fluctuation clauses in recent contracts to prevent raw material cost surges from eroding margins. - Monitor RMB exchange rate impacts on price gaps with imported substitutes (e.g., Vietnamese or Indian polyester yarn), adjusting sourcing mix as needed. - For EU/US customer quotes, reference current FDY/POY cost benchmarks, reserving 3-5% price flexibility.
