New Signals in Nylon Supply Chain: Chip Prices Rise 400 Yuan While Downstream Mills Shift Product Mix

Raw material costs kept climbing while demand stayed flat—this was the defining feature of the nylon filament market in Shengze and Jiaxing during Aug 31-Sep 6. Domestic caprolactam was quoted at 13,450-13,550 yuan/ton, and semi-dull nylon chips rose another 400 yuan/ton week-on-week to 13,900-14,000 yuan/ton. Yet transaction volumes remained subdued, signaling that the rally was cost-driven rather than demand-led.

Cost Pass-Through vs. Demand Mismatch

The 400-yuan weekly jump in chip prices theoretically translates into a 500-600 yuan/ton cost increase for nylon filaments, enough to push up yarn prices across the board. However, the market response was selective: 70D/24F nylon-6 FDY rose to 15,300-15,400 yuan/ton but saw slowing demand due to weak regular nylon taffeta; meanwhile, 40D/24F full-dull FDY gained traction as orders for water-jet woven high-density dull nylon taffeta picked up cyclically. This 'same price hike, different volumes' pattern shows that downstream mills are actively adjusting their product mix to absorb cost pressure.

Notably, 20D/1F and 30D/1F semi-dull yarns saw sluggish sales despite stable prices, while nylon-66 DTY remained illiquid due to its narrow application range. This divergence highlights a growing preference for differentiated and functional fabrics, reducing the effectiveness of blanket price increases for commodity-grade products.

Order Shortage Caps Price Gains

Feedback from the Shengze and Jiaxing industrial belts indicates that large manufacturers saw a slight increase in orders for nylon-blended woven fabrics, but overall demand remained lower than last year. Insufficient fabric orders directly suppressed nylon filament consumption, making it difficult for upstream cost pressure to pass through fully. In other words, this price rise is being 'pushed' by costs, not 'pulled' by demand, casting doubt on its sustainability.

For weavers, rising raw material costs are squeezing processing margins, especially for those producing regular nylon taffeta, who may face a dilemma of 'hard to raise prices, painful to absorb losses.' For buyers, stocking up heavily at this point is not wise—cost support is strong, but weak demand could trigger a pullback. A more prudent approach is to purchase in batches and replenish as needed.

Price Outlook and Operational Strategies

In the short term, nylon filament prices are still likely to edge higher, but the upside may be limited. Strong upstream caprolactam and chip prices provide a floor, while sluggish demand forms a ceiling. Next week, the market is expected to see 'stable-to-firm raw materials, modest filament price hikes, and just-in-time transactions.' Differentiated products like full-dull FDY may remain firmer due to order support, while commodity grades face inventory risks.

For Buyers - Increase procurement of demand-rising items like 40D/24F full-dull FDY to lock in costs. - For regular 70D/24F and semi-dull fine-denier yarns, purchase on a need-basis to avoid inventory devaluation. - Monitor caprolactam price trends; if raw materials soften, delay bulk orders.

For Exporters - Incorporate rising raw material costs into quotations to avoid profit erosion from delayed price adjustments. - For overseas orders, prioritize differentiated products like dull high-density nylon taffeta to avoid price competition on commodity items. - Consider short-term price lock agreements with chip suppliers to reduce raw material volatility impact on export contracts.
