In March 2026, the domestic PA66 spot price continued to rise strongly, entering the "20,000 era". Affected by strong support from the cost side and tight supply, the PA66 market as a whole shows a high to strong oscillation trend, with the price center steadily rising and the mainstream quotation breaking through the 20,000 RMB/ton mark. The benchmark price of SunSirs increased from 15,833.33 RMB/ton at the beginning of the month to 20,533.33 RMB/ton at the end of the month, with a monthly increase of 29.68%.

In terms of cost, crude oil and basic raw materials have surged this month: the geopolitical conflict in the Middle East has pushed Brent crude oil to nearly $120 per barrel, driving pure benzene and ethylene to rise across the board; Pure benzene rose by about 36.8% monthly, while adipic acid rose by about 24.2% monthly. The soaring price of hexamethylenediamine: As the core raw material of PA66, hexamethylenediamine increased from 18,200 RMB/ton in early March to 26,000 RMB/ton in April, a monthly increase of 42.9%, directly pushing up the production cost of PA66.

On the supply side: This month, leading domestic enterprises such as Shenma and Huafeng took the initiative to control production, with an industry operating rate of only 55% -60%; Traders are reluctant to sell and hoard goods, factories and traders have low inventory, and spot circulation is tight. Internationally, the obstruction of Red Sea shipping and the shutdown of the Aoshengde Lianyungang plant have exacerbated the shortage of raw material supply, resulting in a year-on-year decrease of about 15% in imported goods.

In terms of demand, this month's demand is weak but supported by rigid demand. The downstream textile industry has a low acceptance of high prices and mainly relies on small order rigid demand and on-demand procurement, without centralized replenishment; But it is necessary and there has been no significant negative feedback.

In the future, it is expected that the PA66 market price will experience strong fluctuations at a high level in the short term. Starting from April 1st, the price of hexamethylenediamine will be 26,000 RMB/ton, with strong cost support. Due to the tight supply, the price of PA66 is prone to rise but difficult to fall. If geopolitical conflicts ease, crude oil prices fall, or downstream companies continue to observe and procurement further shrinks, prices may experience a slight correction; But the probability of a significant short-term decline is low.
