Manganese Ores and Concentrates

Manganese ores and concentrates classified here must contain at least 20% manganese by dry weight, a threshold that separates commercially viable ore from ferruginous material with incidental manganese content. The US schedule further divides the heading by grade: below 47% manganese (2602000040) and at or above 47% (2602000060), with the higher-grade material commanding premium pricing for direct use in steelmaking alloys. Gabon is the leading US supplier, followed by Mexico and South Africa — a supplier mix that reflects both proximity and the dominance of the Gabonese Moanda deposit in global high-grade manganese supply.
