The outlook for China’s Hexamethylene Diamine (HMDA) market suggests gentle price shifts in the coming months. Experts predict a modest 1% price drop in August 2025, with prices likely to hold steady in September. This expected trend stems from a combination of growing global supply and steady demand from industries relying on HMDA.
Domestic HMDA output is anticipated to be steady, with plants likely to maintain production flat through the two months. The availability of Adiponitrile (ADN), a key feedstock, will be steady, keeping material costs from rising significantly to drive up HMDA prices and keeping manufacturing operations running smoothly.
New HMDA supplies from Europe, particularly following BASF’s expansion of its Chalampé facility, are likely to keep offers in Asia competitive. This boost in global availability will give Chinese buyers access to more affordable import options, which in turn will influence local HMDA pricing trends.
Traders and buyers are expected to lean heavily on inventory strategies to guide their market moves. Many secured their HMDA needs in July and are likely to cut back on spot purchases, choosing instead to draw down existing stocks. This cautious approach leading to a quieter trading activity in August.
The automotive industry continues to provide a solid foundation for HMDA demand. July figures show a 6.9% year-on-year rise in China’s passenger vehicle sales, with new energy vehicles posting an impressive 12% growth, even as hybrid vehicles showed some weakness. This strong performance in the auto sector is expected to keep demand for nylon-6,6 components steady, directly supporting HMDA usage.
The textile sector also contributes to stable HMDA demand. Over the first four months of 2025, major textile manufacturers experienced a 4.2% increase in year-over-year value-added output, while large retailers reported a 5.9% increase in sales. Textile exports rose 1.1%, which reflects steady performance in the sector that supports stable demand growth for nylon-6,6 fibres and, therefore, HMDA.
Demand for nylon-6,6 applications should remain even, which will curb significant swings in HMDA consumption. A stable supply chain from feedstock to final product should encourage HMDA producers to maintain the status quo for pricing, rather than implementing sharp hikes.
The combination of increased European supply, stable raw material costs, and steady off-take in the automotive and textile sectors should result in a balanced HMDA market. This balance supports our forecast price path through September 2025.
Looking ahead, industry participants anticipate continued balance as the combination of moderated growth in global supply and stable demand dominant trends. Competitive import offers will likely continue to shape domestic HMDA prices, while steady nylon-6,6 consumption ensures ongoing demand support for HMDA through the forecast period.
