16,075 yuan per tonne — that is the nylon POY benchmark price on October 2, unchanged from the start of the month. But stretch the timeline to a full year, and that figure conceals a 4,775 yuan rally: the annual low was just 11,300 yuan, and the price now sits in the upper band of its yearly range, only 875 yuan below the peak of 16,950 yuan. The annual average of 13,399.59 yuan and median of 14,125 yuan both point to the same conclusion — the price centre of nylon POY has shifted upward materially over the past twelve months.
Price Structure: Three Forces Behind the High-Level Plateau
A daily change of 0.00% suggests the market has entered a brief calm. Yet what matters more than the magnitude of the move is where the price sits. The narrowing top gap of 875 yuan means the annual ceiling is close; the wide bottom gap of 4,775 yuan shows the current level is more than 40% above the yearly low. This "near the top, far from the bottom" structure typically appears in the later stage of a cost-driven rally.
The first force comes from raw materials. Caprolactam, the core feedstock for nylon POY, directly sets the cost floor for chip and spinning operations. Over the past year, firm feedstock prices have prevented nylon POY from breaking below cost support even during weak demand seasons. The second force is the pace of capacity additions. Some new plants came on stream later than expected, so supply increments did not match the speed of demand recovery. The third force is restocking by downstream weaving mills — once prices break through key levels, the fear of missing out becomes self-reinforcing.
For buyers, distinguishing among these three forces matters: cost push is rigid, capacity timing is variable, and restocking sentiment is fragile.
Industry Impact: Cost Transmission from Chip to Fabric
The high price of nylon POY is transmitting downstream, but the efficiency of that transmission is uneven. In nylon filament clusters such as Changle in Fujian and Xiaoshan in Zhejiang, spinning mills are seeing their processing margins squeezed most acutely — the higher the share of raw material costs, the less bargaining power they retain. Some small and medium-sized texturing plants already face a "loss on every order" dilemma, and operating rates are diverging.
Looking further downstream, nylon POY mainly feeds texturing, weaving and warp-knitting. Categories such as sportswear fabrics, yoga apparel and swimwear are highly dependent on nylon filament, and cost pressures will gradually appear in greige fabric quotations. Whether fabric mills can pass on price increases depends on the acceptance of terminal apparel brands. With export orders dominated by short and urgent runs, brands have low tolerance for price volatility, resulting in a clear lag and discount in cost transmission.
Notably, the substitution relationship between nylon and polyester is quietly shifting. When nylon POY stands above the 16,000 yuan range while polyester filament prices remain relatively moderate, some orders with less extreme performance requirements will migrate to polyester or blended solutions. This substitution will not happen overnight, but it adds a weight to the procurement decision balance.
Trend Judgment: High-Level Oscillation or Peak Reversal
The annual peak of 16,950 yuan and the 875 yuan top gap provide the most direct technical reference. Historically, when prices approach the annual high and momentum slows, the market typically enters one of two states: either plateauing at a high level to digest earlier gains while awaiting new drivers, or retreating under the dual pressure of profit-taking and demand falsification.
Three key variables determine the direction. First, caprolactam supply — if feedstock loosens, cost support for nylon POY will weaken. Second, the sustainability of downstream weaving orders — whether the traditional peak season translates into actual consumption rather than mere inventory transfer between intermediate stages. Third, the macroeconomic trade environment — restocking cycles in major export markets and currency fluctuations directly affect the stability of terminal demand.
Based on current information, a sharp near-term decline is unlikely, but a further breakout above the 16,950 yuan peak also requires new catalysts. The more probable path is wide-range oscillation at a high level, with the price centre holding between 15,500 and 16,500 yuan.
