On August 31, the benchmark price of nylon FDY settled at 17,000 yuan/ton, up 3.03% from the start of the month. This level sits exactly at the midpoint of its one-year trading range, yet over the past 12 months, the product has seen a low of 14,175 yuan/ton and a high of 19,950 yuan/ton, an amplitude of nearly 28%. The upward shift in the price center is not a one-day anomaly but the result of a three-way tug-of-war among raw material costs, operating rates, and end-order demand.
Market Background
Annual statistics show that the average price of nylon FDY over the past year was 15,839.82 yuan/ton. The current price is about 7.3% higher than that average, indicating that the market has clearly recovered from last year's low range. The gap to the yearly high is -2,950 yuan/ton, while the gap to the low is +2,825 yuan/ton. With over 2,800 yuan of upside and downside elasticity, the divergence between upstream and downstream expectations is widening.
The immediate driver of this rise is the strengthening of raw material prices such as caprolactam. Raw materials account for over 70% of nylon FDY's cost structure; for every 1% fluctuation in raw material prices, finished product prices tend to follow by about 0.7%. In August, raw material supply tightened due to maintenance at several plants and reduced import arrivals, significantly bolstering cost support.
Meanwhile, downstream weaving mills generally held medium-to-low raw material inventories. During the earlier low-price period, most factories purchased on a need-to-order basis and did not build substantial safety stocks. As prices entered an upward channel, restocking demand was unleashed, further amplifying the short-term supply-demand mismatch.
Industry Impact
For nylon filament factories, the 17,000 yuan/ton level means that per-ton gross margins have recovered from near-breakeven earlier this year to a reasonable range. However, the zero daily change suggests that upward momentum is weakening and the market may enter a wait-and-see phase. If factories blindly chase higher raw material inventories, they risk inventory write-downs if prices fall.
For downstream fabric mills, the lag effect of cost pass-through deserves attention. Nylon FDY price changes typically reflect in gray fabric and finished fabric quotes within two to four weeks. If the current price persists through mid-September, cost calculations for autumn/winter fabric orders will rise noticeably, and some export orders won on low bids may face margin squeeze.
Across industrial clusters, price quotes in major nylon hubs such as Changle in Fujian and Yiwu in Zhejiang have begun to diverge: large mills, with higher proportions of long-term contracts, quote relatively stable prices, while small and medium mills adjust flexibly, widening price gaps to 300–500 yuan/ton. This divergence will likely push some orders toward cost-advantaged leaders, further increasing industry concentration.
