Report summary
At the end of October 2026, Wood Mackenzie had the opportunity to visit brine operations across Qinghai province, conducting a five-day site visit to Xining and Golmud. We met with representatives from four brine producers and one new entrant in aluminium-ash recycling, discussing production costs, winter output patterns, downstream demand conditions, and longer-term expansion plans. The trip coincided with a period of sustained price weakness and considerable uncertainty over market direction, making it a valuable opportunity to examine the role that brine producers are playing in this cycle. Key questions we sought to answer included: how Qinghai producers are responding to low prices, how significant winter output cuts are in practice, and where incremental domestic brine supply is likely to come from next. Please download the attached report to find out more.
Table of contents
- The seasonality narrative is weakening, and brine output is stable
- Brines sit on the left of the cost curve, and their supply is inelastic
- Future growth is shifting to Tibet, but will be released slowly
- Downstream has firm demand, but sentiment varies with producers' sales structure
- Aluminium ash producers are insensitive to price swings
