Products classified under HTS 2602.00.00.40
Ferruginous Manganese Ore (32% Mn)
A naturally occurring ferruginous manganese ore with 32% manganese content by dry weight and less than 47% total manganese, including iron oxides. Classified under HTS 2602.00.0040 due to its manganese concentration between 20% and under 47% by weight. Used primarily in steel production as a flux and alloying agent.
Low-Grade Psilomelane Concentrate (28% Mn)
Concentrated psilomelane ore, a manganese oxide mineral, with 28% manganese by dry weight and under 47% total. Falls under HTS 2602.00.0040 for manganese ores and concentrates meeting the 20-47% threshold. Commonly beneficiated for use in ferroalloy production.
Manganiferous Iron Ore (25% Mn)
Manganiferous iron ore blend containing 25% manganese by dry weight, less than 47%, with significant iron content. Classified in HTS 2602.00.0040 as ferruginous manganese ore ≥20% Mn. Sourced from deposits like those in Australia for metallurgical applications.
Braunite Manganese Concentrate (35% Mn)
Concentrate from braunite mineral (Mn2O3) with 35% manganese content by dry weight, under 47%. HTS 2602.00.0040 applies to such natural concentrates ≥20% Mn. Utilized in the production of silicomanganese alloys.
Pyrolusite Ore Fines (22% Mn)
Fines from pyrolusite (MnO2) ore with 22% manganese by dry weight, less than 47%. Fits HTS 2602.00.0040 for manganese ores ≥20% Mn. Processed into chemical manganese dioxide or used in batteries.
Rhodochrosite Manganese Ore (40% Mn)
Rhodochrosite (MnCO3) ore with 40% manganese content dry weight, under 47%. Under HTS 2602.00.0040 as qualifying manganese concentrate. Mined for flux in steelmaking and manganese metal production.
Mixed Manganese Silicate Ore (30% Mn)
Silicate-based manganese ore mix with 30% Mn by dry weight <47%. HTS 2602.00.0040 for ferruginous or mixed ores ≥20% Mn. Applied in silicomanganese smelting operations.
