At 15,525 CNY per ton, the benchmark price of nylon POY on September 9 marks a 6.15% increase from the beginning of the month, with a daily surge of 4.37%. This level sits in the middle-to-high range of the past year, yet remains about 8.4% below the annual peak of 16,950 CNY. The upward shift in the price center is no accident—it reflects a rebalancing of the nylon chain under dual pressures from costs and demand.
A Rising Price Center: Higher Floor and Reshaped Average
Zooming out to the period from September 2025 to September 2026, nylon POY prices bottomed at 11,300 CNY, peaked at 16,950 CNY, with a median of 14,125 CNY and an average of 13,147.75 CNY. The current price exceeds the average by 18.1% and the median by 9.9%. This data structure indicates that the price center has shifted significantly upward from the lows of a year ago, with the floor rising by 4,225 CNY and a remaining 1,425 CNY gap to the top.
From an annual perspective, the current price sits in the upper-middle zone, meaning prices were higher less than half of the time over the past 12 months. For buyers and mills, this positioning serves as a crucial pricing reference. For weaving enterprises, where raw materials account for a large share of costs, every 100 CNY rise in POY adds roughly 0.1 CNY per meter to fabric costs (based on standard specifications), forcing downstream players to lock in raw materials more cautiously when taking orders.
Cost Transmission and Demand Resilience: Twin Engines of the Rally
The primary driver behind this price increase is robust upstream raw material costs. Caprolactam, the direct precursor to nylon POY, typically transmits its price fluctuations to the nylon segment within one to two weeks. Public industry data indicates that recent maintenance at caprolactam plants has reduced operating rates to around 70%, tightening spot supply and supporting firm prices. For nylon manufacturers, this cost-push inflation means profit margins are not necessarily expanding; in fact, they may face pressure if raw material costs rise faster than product prices.
On the demand side, the market is not entirely indifferent. Autumn marks the traditional peak season for nylon fabrics. Procurement of nylon POY for outdoor sportswear and down jackets usually increases by 15%-20% month-on-month. This year, brands' growing preference for lightweight and functional materials aligns well with POY's high strength and abrasion resistance, lending resilience to orders. A trader from the Shengze area reports active inquiries for POY, but actual transactions are mostly limited to essential restocking, with little speculative stockpiling.
Notably, a daily gain of 4.37% is unusual in nylon POY trading history, typically occurring when upstream markets experience sudden disruptions or when market sentiment concentrates. Such impulsive surges are rarely sustainable, and the market is likely to enter a consolidation phase to absorb the gains. For buyers relying on monthly quotations, it is unwise to chase prices at current levels; instead, they may consider accumulating positions in batches when prices retreat to around 15,000 CNY.
Industrial Impact and Regional Linkages
Price fluctuations do not occur in isolation; they trigger chain reactions across the industry. For upstream nylon chip producers, higher POY prices help improve operating rates, but they must remain vigilant against rising raw material costs eroding profits. For downstream texturizers and weavers, every 1% increase in POY price raises the theoretical costs of DTY (drawn textured yarn) and nylon fabrics by approximately 0.8% and 0.6%, respectively, squeezing already thin processing margins.
From a regional perspective, the nylon clusters in Xiaoshan and Shaoxing (Zhejiang) and the warp-knitting base in Changle (Fujian) are most sensitive to POY price movements. A chemical fiber enterprise in Xiaoshan notes that if POY prices stabilize above 15,500 CNY, downstream order quotations must be raised to cover costs. Meanwhile, warp-knitting mills in Changle may switch to slightly lower-priced semi-dull or dull POY variants to balance expenses. This micro-adjustment in product mix is a natural market mechanism driven by price signals.
