PRICING NOTICE: Launch of weekly Manganese Ore Index 37% Mn, cif Tianjin

Metal Bulletin has launched a weekly Manganese Ore Index 37% Mn, cif Tianjin China $ per dmtu of metal contained.

Launched after a consultation period, the new index will complement the two existing manganese ore prices, the 37%Mn fob Port Elizabeth South Africa Manganese ore index and the Manganese Ore Index 44% Mn, cif Tianjin $ per dmtu of metal contained.

Strong demand from China’s domestic steel market has facilitated a change in spot contract terms in the 37% manganese ore market over the past two years, with deals now increasingly concluded on a cif China basis, according to data collected by Metal Bulletin.

Recently, manganese ore prices have been especially volatile. Particularly, the manganese ore 37% fob index.
