Subheadings
Products classified under HTS 2610.00.00
Chromite Ore Lumps
Chromite ore in lump form, primarily consisting of iron chromium oxide (FeCr2O4), used as the main source for chromium extraction in ferrochrome production. Classified under HTS 2610.00.00 as chromium ores and concentrates due to its high chromite content and direct use in metallurgical processes. Typical lump sizes exceed 6.35 mm after crushing from mined rock.
Chromite Sand Concentrate
Fine chromite sand concentrate produced by gravity separation from ore deposits, with Cr2O3 content over 46%, used in foundry molding and steel production. Falls under HTS 2610.00.00 as a chromium concentrate derived from natural ores without chemical processing. Particle size typically 0.1-2.0 mm for industrial applications.
South African UG2 Chromite Concentrate
UG2 chromite concentrate from platinum group metal tailings in South Africa, containing 42-48% Cr2O3 with platinum byproducts, used for ferrochrome smelting. Classified as HTS 2610.00.00 for its primary chromium ore value despite PGM content. Produced via flotation and magnetic separation.
Turkish Chromite Ore Fines
High-grade chromite ore fines (-6mm) from Turkish deposits with 48-52% Cr2O3, used in stainless steel and chrome chemical production. HTS 2610.00.00 classification applies to these natural chromium ores beneficiated only by physical means like screening. Low silica content makes it premium metallurgical grade.
Indian Metallurgical Chromite Concentrate
Metallurgical grade chromite concentrate from Odisha mines, 46-50% Cr2O3 with Cr/Fe ratio >2.8:1, essential for ferrochrome submerged arc furnaces. Classified under HTS 2610.00.00 as beneficiated chromium ore product via dense media separation. Supplies 40% of global chrome needs.
Zimbabwean High-Carbon Ferrochrome Ore
Lumpy chromite ore from Great Dyke deposits in Zimbabwe, suitable for high-carbon ferrochrome production with 42-46% Cr2O3. HTS 2610.00.00 covers this primary chromium-bearing ore used directly in smelting operations. Known for consistent quality and low impurities.
Philippine Chromite Ore Pellets
Agglomerated chromite ore pellets from Masinloc mines, 48% Cr2O3, formed using bentonite binders for easier furnace charging. Still classified as HTS 2610.00.00 since physical agglomeration doesn't constitute chemical change from natural ore. Improves bulk density for transport efficiency.
Kazakhstan Chromite Flotation Concentrate
Ultra-fine chromite concentrate (<0.1mm) from froth flotation processing of low-grade Kazakh ores, achieving 52% Cr2O3 recovery. HTS 2610.00.00 applies to physically concentrated chromium ores without smelting or leaching. Used in powder metallurgy applications.
Madagascan Chemical-Grade Chromite Concentrate
High-purity chromite concentrate from northern Madagascar with 46-50% Cr2O3 and low iron, used for sodium dichromate production via roasting and leaching. HTS 2610.00.00 classification for unroasted chromium ores destined for chemical processing. Physical concentration only.
Brazilian Refractory Chromite Ore
High-magnesia chromite ore from Goias deposits with 30-40% Cr2O3 and 15-20% MgO, ideal for chrome-magnesite refractory bricks. Classified HTS 2610.00.00 as natural chromium ore suitable for both metallurgical and refractory uses based on composition. Mined and crushed without chemical treatment.
