Products classified under Tariff item 2602.00.00
Braunite Manganese Concentrate (35% Mn)
This braunite concentrate contains 35% manganese by dry weight, derived from the mineral braunite (Mn2O3). It meets the 20% threshold for tariff item 2602.00.00 and is used in the production of silicomanganese alloys. The concentrate is produced through mechanical beneficiation.
Braunite Manganese Ore
Braunite is a manganese silicate mineral commonly found in metamorphic deposits. This ore contains 24% manganese by dry weight, which meets the 20% threshold for classification under tariff item 2602.00.00. It is used in the metallurgical industry for the production of manganese alloys.
Ferruginous Manganese Ore (32% Mn)
This naturally occurring ferruginous manganese ore contains 32% manganese by dry weight, exceeding the 20% threshold for tariff item 2602.00.00. It includes iron oxides and has a total manganese content below 47%. It is used in ferro-manganese production.
Hausmannite Manganese Ore
Hausmannite is a manganese oxide mineral (Mn3O4) that occurs in hydrothermal veins. This ore contains 22% manganese by dry weight, qualifying it as a manganese ore under tariff item 2602.00.00. It is a ferruginous type, meaning it contains significant iron content.
High-Grade Manganese Ore
High-grade manganese ore contains more than 44% manganese on a dry weight basis, well above the 20% minimum for tariff item 2602.00.00. This natural ore may include ferruginous varieties with iron impurities. It is used primarily in steelmaking and alloy production.
Low-Grade Psilomelane Concentrate (28% Mn)
This psilomelane concentrate contains 28% manganese by dry weight, produced through mechanical beneficiation of psilomelane ore. It meets the 20% threshold for tariff item 2602.00.00. The concentrate is commonly used in steelmaking applications.
Manganese Ore Concentrate
This manganese ore concentrate is produced through mechanical processes such as crushing, screening, and gravity separation. With 38% manganese content on a dry weight basis, it exceeds the 20% threshold for tariff item 2602.00.00. The concentrate has not been chemically altered, maintaining its classification as an ore concentrate.
Manganese Ore Fines
Manganese ore fines are crushed particles smaller than 6mm produced during beneficiation. With 32% manganese content on a dry weight basis, these fines qualify under tariff item 2602.00.00. They are classified as manganese ore concentrates because they meet the 20% manganese threshold.
Manganiferous Iron Ore (25% Mn)
Manganiferous iron ore contains 25% manganese by dry weight with significant iron content. This blend qualifies as ferruginous manganese ore under tariff item 2602.00.00 because the manganese content exceeds 20%. It is sourced from deposits with mixed iron and manganese mineralization.
Manganite Manganese Ore
Manganite is a hydrated manganese oxide mineral found in oxidized zones of ore deposits. This ore contains 28% manganese by dry weight, meeting the 20% threshold for tariff item 2602.00.00. It is used in the production of manganese alloys and chemicals.
Medium-Grade Ferruginous Manganese Ore
Medium-grade ferruginous manganese ore contains 25-35% manganese with significant iron impurities. This sedimentary ore exceeds the 20% manganese threshold on a dry weight basis, qualifying for tariff item 2602.00.00. It is used in ferro-manganese production.
Mixed Manganese Silicate Ore (30% Mn)
This mixed manganese silicate ore contains 30% manganese by dry weight, below the 47% threshold. It qualifies for tariff item 2602.00.00 as a ferruginous or mixed manganese ore. It is applied in silicomanganese smelting operations.
Psilomelane Manganese Ore
Psilomelane is a manganese oxide mineral aggregate mined from oxide deposits. This ore contains 30-40% manganese oxide, which translates to a manganese content exceeding 20% on a dry weight basis. It qualifies for tariff item 2602.00.00 as a manganese ore.
Pyrolusite Manganese Ore
Pyrolusite is the primary manganese dioxide ore, and this product consists of ore lumps with 35% metallic manganese equivalent on a dry basis. This high manganese purity exceeds the 20% threshold for tariff item 2602.00.00. It is sourced from South African mines.
