The nylon POY benchmark price stands at 16,075 yuan per tonne, unchanged from the start of the month. Yet the real story is not the flat reading itself, but the fact that it sits 4,775 yuan above the annual low of 11,300 yuan. Over the past year, prices have ranged between 11,300 and 16,950 yuan per tonne, with a median of 14,125 yuan. The current level is clearly near the top of that band, just 875 yuan shy of the annual peak. For downstream weavers and fabric makers, a higher cost centre is now a given.
Price Structure: A High Plateau Is Trickier Than a Spike
Looking at the annual statistics, the average nylon POY price is around 13,436 yuan per tonne, and the current level is nearly 20% above that mean. This means that even if prices stop rising, downstream players cannot return to the earlier low-cost range. In a sharp rally, buyers can wait for a pullback. On a high plateau, that room for manoeuvre narrows: factories either accept the cost or cut operating rates.
Why can prices hold so firm? On one side, upstream caprolactam and raw material costs continue to provide support. On the other, demand for nylon in sportswear, outdoor gear and functional fabrics keeps growing, with no visible collapse on the consumption side. Supply and demand together leave little room for a significant downward correction.
For buyers, the current level means the window for locking in prices is limited. If upstream costs move higher, nylon POY could test the annual peak of 16,950 yuan. Conversely, if end-user orders weaken, the risk of a pullback from these highs is equally real. This two-way uncertainty is exactly what makes a high plateau so tricky to navigate.
Industrial Transmission: The Cost Chain from Chips to Fabric
Nylon POY sits in the midstream of the chain, and its price movements transmit in two directions. Upstream, it is pulled by caprolactam and chip prices. Downstream, it directly affects DTY, FDY and other textured yarn prices, which then feed into weaving, dyeing and finished fabrics. With POY firm, downstream yarn prices are unlikely to soften in the short term.
In chemical fibre belts such as Zhejiang, Jiangsu and Fujian, weaving mills typically quote on a cost-plus-processing-fee basis. Every 1,000 yuan per tonne increase in POY lifts fabric costs accordingly, while processing fees are hard to raise in a fiercely competitive market. This creates a real dilemma: raw material cost increases pass through easily, but processing fee increases are difficult for customers to accept.
For mills focused on nylon-based sportswear, underwear and outdoor functional fabrics, margins are being squeezed from both ends. On one side is rigid raw material cost; on the other, price negotiations with brand clients and export orders. Some small and medium-sized mills may choose to lower operating rates to avoid losses, which in turn affects delivery schedules for downstream yarn and greige fabric.
It is worth noting that nylon has some substitutability with polyester and spandex. If nylon prices stay high, some orders may shift to polyester blends, especially in cost-sensitive regular categories. This substitution effect will not be immediate, but it can change procurement structures at the quarterly level.
