In late August, nylon filament prices in Shengze and Jiaxing saw a collective uptick, yet trading volumes remained steady. This combination of rising prices and flat sales typically signals cost-push inflation being gradually absorbed downstream, rather than a demand-led recovery. For buyers, the next move hinges on upstream raw material sustainability and weavers' acceptance.
Price Gradients and Specification Divergence
According to public quotations, monofilament products command significantly higher prices than multifilament and FDY. For instance, semi-dull nylon monofilament 17D/1F is quoted at CNY 18,800/ton, 20D/1F at CNY 18,700/ton, while 30D/1F drops to CNY 17,600/ton, showing a clear premium for fine denier. This gradient reflects processing complexity and end-use: fine denier monofilaments are used in high-grade fabrics and seamless underwear, requiring higher quality and thus offering greater price elasticity.
In contrast, multifilament products are cheaper: 30D/10F semi-dull multifilament at CNY 14,700/ton, and 70D/12F bright trilobal at CNY 13,400/ton. In FDY series, 40D/12F nylon-6 FDY is quoted at CNY 16,000/ton (Hai'an), while 210D/36F stands at CNY 13,200/ton, with coarse denier showing clear cost advantages. Notably, full dull FDY prices slightly exceed semi-dull: 40D/12F full dull at CNY 16,600/ton (Zhejiang), and 40D/24F full dull at CNY 16,900/ton, indicating that matting treatment adds cost and corresponds to specific end uses.
Regional price differences are also noteworthy: domestic 70D/24F nylon-6 FDY is CNY 14,900/ton, while 160D nylon-6 ATY full dull from Shandong is CNY 15,900/ton and from Taiwan CNY 16,000/ton. These gaps may stem from raw material costs, freight, and local supply-demand, offering cross-regional arbitrage opportunities.
Cost Pass-through and Market Response
The direct driver of this price hike is rising upstream raw material costs. Nylon filament's primary raw material is caprolactam, whose price fluctuations transmit quickly along the supply chain. However, despite raw material increases, nylon filament sales are described as 'average', indicating weavers are not panic-buying but purchasing on demand. This could reflect weak terminal orders or expectations of a pullback after the hike.
Historically, cost-push inflation without demand support is hard to sustain. But if raw materials remain strong, nylon filament prices are likely to adjust further upward. For weavers, this means higher production costs and squeezed margins; for traders, there is a risk of inventory devaluation.
Industrial Cluster Linkages and Outlook
Shengze and Jiaxing are key nylon filament distribution hubs, and their quotations serve as bellwethers. The synchronized price increases reflect regional consensus on cost pressure. However, increases may diverge by specification: fine denier and differentiated products, with concentrated supply, may pass through costs more smoothly, while conventional coarse denier faces intense competition and limited upside.
Future trends depend on three factors: whether caprolactam prices stabilize, changes in downstream weaving operating rates, and the seasonal recovery of apparel and home textile demand. If demand remains weak, nylon filament prices may fluctuate at high levels; if peak season demand materializes, hikes could be absorbed.
