It was originally proposed to start publishing the alumina index on a daily basis from Monday 27 November. The frequency change has been postponed until December 1 to provide a full month of weekly pricing for the month of November.

The consultation period for the proposed changes to the fob Brazil alumina index and the fob Australia alumina index closed on Friday November 24.

Other amendments to the fob Australia and fob Brazil alumina indices, as outlined in the original consultation notices, will also come into effect on Friday December 1:
- Metal Bulletin will reduce the minimum tonnage requirement for the fob Australia and fob Brazil alumina indices to 5,000 tonnes, from 10,000 tonnes previously. 
- The deadline for data submission will change to 3pm London time from 2pm previously. Indices will be published between 3pm and 4pm on their respective publication days.
- The frequency of the inferred fob Brazil alumina index will be increased to daily, to match the daily publication of the benchmark fob Australia alumina index.
