Raw material provided short-term support

In terms of cost: In June 2025, the spot market price of caprolactam was stronger, and the settlement price of Sinopec's high-end caprolactam in June was 9,720 RMB/ton, an increase of 250 RMB/ton from the settlement price in May. The market price of polyamide PA6 high-speed spinning low-viscosity semi-light showed a trend of "falling-rising-falling". As of June 27, 2025, the benchmark price of caprolactam in the SunSirs was 9,423 RMB/ton, and the price rose strongly, with a monthly increase of 2.54%. During the month, the market price of polyamide PA6 slices and high-speed spinning slices rose slightly, and the price of polyamide PA6 increased by 2.51% month-on-month, mainly due to strong support on the cost side.

Supply pressure was high and demand was weak

The month-on-month increase in polyamide production, coupled with the poor transaction, the inventory pressure of polyamide factories had not decreased. Downstream orders continued to be small, grey fabric inventory level was high, coupled with small profits, slow collection, and tight funds, which led to low enthusiasm for weaving enterprises, only to maintain rigid production, polyamide factory shipments were not smooth.

Forecast for the future

In July, the cost side of the polyamide industry chain is empty, the cost support of raw material caprolactam weakens, and the downstream polyamide PA6 social inventory is digested slowly, and the purchase of caprolactam is cautious, and the upstream and downstream are not good, the price may decline, the cost is transmitted downward, and the price of the polyamide industry chain may show a downward trend.

On the supply side, some manufacturers have plans to put equipment into production in July, and some manufacturers may increase production, in addition, the demand may be weak, so it is expected that the inventory pressure of polyamide factories will be difficult to ease. On the demand side, the domestic order production of downstream weaving enterprises is in the off-season; On the whole, it is expected that the cost side is empty, the supply pressure is large, the downstream weaving enterprises maintain rigid production, the demand is still weak, on the whole, the good is insufficient, and the SunSirs’ analysts expect that the price of polyamide will be downward under pressure in June.
