Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If iron ore with minor molybdenum
Coarse iron ores (particles >4.75mm per notes) under 2601 if iron is dominant.
If oxidized and roasted
Roasting changes classification to processed concentrates.
If industrial residues with Mo and arsenic
Heading 2620 for arsenic-containing slag/ash used in extraction.

Import Tips & Compliance
• Account for variable hydration water in assay quantities per statistical notes for precise duty calculation
• Ensure no arsenic content exceeds thresholds to avoid reclassification under 2620 arsenic residues
• Document mining origin to differentiate from synthetic or waste-derived materials
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.
Mixed Molybdenum Flotation Concentrate
Flotation concentrate blending molybdenite and oxide minerals (e.g., wulfenite, powellite) at 45% Mo grade from polymetallic deposits. Classified as HTS 2613.90.00.00 'other' since not purely roasted molybdenite. Key input for ferroalloy production.
