Import Tips & Compliance
• Break down mineral composition in entry docs for customs verification of 'other' status
• Test for copper impurities; high levels may trigger 2603 classification
• Use sealed samples for disputes on metal content deductions
Related Products under HTS 2613.90.00.00
Molybdenite Ore Concentrate
Molybdenite ore concentrate is a primary source of molybdenum, typically containing 40-60% molybdenum disulfide (MoS2) after flotation processing from mined ore. It falls under HTS 2613.90.00.00 as 'other' molybdenum ores and concentrates, excluding roasted molybdenite which is classified separately under 2613.10. This product is used in steel alloy production and chemical manufacturing.
Wulfenite Molybdenum Ore
Wulfenite (PbMoO4) is a lead molybdate mineral ore processed into low-grade concentrates for molybdenum recovery. Classified under HTS 2613.90.00.00 as 'other' molybdenum ores, distinct from molybdenite, it requires specialized extraction due to lead content. Used primarily in molybdenum chemical production.
Powellite-Bearing Molybdenum Concentrate
Powellite (CaMoO4) concentrate from skarn deposits, containing 20-30% molybdenum oxide, processed via flotation. It is categorized under HTS 2613.90.00.00 for other molybdenum ores and concentrates, separate from common molybdenite. Primarily used in superalloy manufacturing.
Ferrimolybdite Molybdenum Ore
Ferrimolybdite (Fe2(MoO4)3·nH2O) is a hydrous iron molybdate ore from oxidized deposits, yielding concentrates with 15-25% Mo. Falls under HTS 2613.90.00.00 as other molybdenum ores, used in hydrometallurgical recovery for catalysts.
