Final decision on open consultation on methodology for IOSCO-audited manganese ore indices

Fastmarkets invited feedback from the industry on the pricing methodology for its International Organization of Securities Commissions (IOSCO)-audited manganese ore indices, via an open consultation process between March 25 and April 27, 2026.

This consultation was done as part of Fastmarkets’ published annual methodology review process.

No feedback was received during the consultation period and therefore no changes will be made to the methodologies at this stage.

This consultation sought to ensure that our methodologies continue to reflect the physical market for our audited physical markets for steel scrap, in compliance with IOSCO’s principles for Price Reporting Agencies (PRAs). This includes all elements of our pricing process, our price specifications and publication frequency.

The prices under review were:

MB-MNO-0001 Manganese ore high grade index, cif Tianjin, $ per dmtu

MB-MNO-0003 Manganese ore semi carbonate index, 36.5% Mn, cif Tianjin, $/dmtu

MB-MNO-0002 Manganese ore semi carbonate index, 36.5% Mn, fob Port Elizabeth, $/dmtu

Full details of the prices covered by this consultation can be found here.

This decision notice was delayed past its original May 4 schedule.
