PRICING NOTICE: Correction to pricing rationale of Fastmarkets’ manganese ore 37% cif China index

Fastmarkets has corrected the pricing rationale for its manganese ore 37% index cif China that was published incorrectly on Friday October 25 due to a reporter error.

Two offers of $4.00 per dmtu, which were reported by buyers, and one trade of medium-sized volume at $4.22 per dmtu were included in the rationale as data points used to calculate Fastmarkets’ weekly manganese ore index 37% Mn, cif Tianjin

But they had been automatically discarded as outliers, in accordance with Fastmarkets’ methodology. All data points that fall more than 10% away from the initial calculated index are automatically excluded – the index is then recalculated. 

Fastmarkets’ rationale database has been updated to reflect this change. There is no change to the index number, however, which was published correctly at $3.50 per dmtu on October 25.

For more information or to provide feedback on this correction notice or if you would like to provide price information by becoming a data submitter to this index, please contact Jon Stibbs by email at Please add the subject heading ‘FAO: Jon Stibbs re: Manganese ore index.’
