The prices of Hexamethylene Diamine in USA were up by about 0.5% in November 2025, supported by stable supply and mild seasonal consumption from coatings and adhesives applications. However, the automotive and textile industries continued to buy cautiously in a moderate market.
US Hexamethylene Diamine Market was sturdy in November 2025. Prices remained relatively stable as supply-demand balance well maintained. After a neutral trading atmosphere in October, this month the market is supported by weak seasonal increases in the consumption of downstream, especially from coatings and adhesives. Hexamethylene Diamine manufacturing activity has remained steady with domestic producers continuing to run to fill the stable order flow from applications in the nylon 6,6 resins and industrial markets.
Market players noted that the price of Hexamethylene Diamine was up about 0.5% in November, with a weak seasonal support rather than the change of market fundamentals. This slight improvement relates to cautious end of the year restocking by buyers to stock up in anticipation of possible supply interruptions. Although there was a slight increase, the feedstock prices remained stable during the period, which limited the volatility in Hexamethylene Diamine prices and kept them from falling further as in the previous month.
The performance of the automotive industry is still having an impact on the Hexamethylene Diamine consumption, with lower vehicle sales in October creating delayed effects on demand for nylon 6,6 intermediates. Production figures showed that U.S. auto sales in October fell to around 1.27–1.30 million units, down almost 6% from the previous month. This slowdown in automotive production has dampened short-term demand growth but producers believe that Hexamethylene Diamine demand will slowly start to pick up as the market begins to stabilize.
Likewise, the cautious purchase approach in the textile industry has restrained additional Hexamethylene Diamine usage over the same period. Manufacturing data for October highlighted a continued fragile sector, with purchasing staying subdued despite forecasts for longer-term expansion. This prudent purchasing behaviour has solidified the stable Hexamethylene Diamine price environment as downstream producers are refraining from building up their inventories too much, while still ensuring that they maintain necessary production levels.
Looking forward to December 2025, Hexamethylene Diamine prices will be steady due to the standard demand from downstream applications of nylon 6,6 caused by the holiday season. Production conditions would be well balanced as producers would keep stable run rates without significant interruptions. The feedstock situation is expected to remain stable, which will keep Hexamethylene Diamine cost pressure neutral and the price stable.
As the market moves towards January 2026, Hexamethylene Diamine prices are to rise by around 1% as a result of seasonal restocking in the downstream sectors after the pause in December. Early signs of recovery in automotive and textile demand will add to incremental usage gains. Supply chains can be expected to remain smooth throughout this timeframe however demand growth should exert upward price pressure.
