Multiple Factors Dragged July Alumina Operating Capacity Lower YoY; August Production Resumption Expectations Strengthened [SMM Analysis]

SMM July 31:

In July 2026, China's metallurgical-grade alumina production edged up 2.18% MoM but fell 2.48% YoY. As of end-July, China's existing capacity stood at around 118.42 million mt/year, and overall operating capacity fell 1.18% MoM, with a YoY decline of 2.48%.

The month's operating capacity decline was mainly due to multiple regional factors, with operating rates diverging among enterprises: In south China, after previous boiler failures forced production suspensions, some lines in Guangxi gradually resumed operations in July, with operating capacity recovering to around 3 million mt/year by month-end, providing some support to regional production. However, another alumina refinery in Guangxi proactively cut production due to technical issues, capping the recovery pace in the region. In Guizhou, tighter domestic bauxite ore supply led enterprises to flexibly adjust production plans, coupled with routine maintenance, resulting in a slight production decline; however, one enterprise in the region steadily ramped up production after earlier stoppages, lifting Guizhou's production slightly. In north China, an enterprise in Shanxi failed to resume production this month due to problems at its red mud pond, becoming the main drag on regional output. Meanwhile, many areas in the north faced tighter bauxite ore supply, further curbing operating rates and causing an overall production decline in the region.

Looking ahead to August, China's metallurgical-grade alumina production is expected to recover somewhat. On one hand, maintenance and boiler issues in Guangxi are likely to be largely resolved, allowing production to return to normal levels; the red mud pond issue in Shanxi is expected to be dealt with by mid-August, enabling the restart of related capacity; additionally, domestic bauxite ore supply may also improve modestly, providing raw material support for production growth. Although maintenance shutdowns are still expected in some regions, the overall production additions from restarts are anticipated to exceed the losses from maintenance. The operating capacity of metallurgical-grade alumina in China is projected to remain at around 89.2 million mt/year in August.
