Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If post-roasting or calcining
Thermal processing converts oxide ores to roasted concentrates under 2613.10.
If processed into borates or natural compounds
Certain natural borates and chemical compounds shift to Chapter 25 if not qualifying as ore.
If slag/ash residues containing molybdenum
Chapter notes limit 2620 to industrial residues for metal/compound extraction, not primary ore.

Import Tips & Compliance
• Provide detailed mineralogical reports distinguishing powellite from roasted forms to avoid 2613.10 misclassification
• Comply with REACH-like regulations for calcium and trace rare earth elements in the concentrate
• Monitor particle size if coarse (>4.75mm similar to iron ore notes) for accurate quantity reporting
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.
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.
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.
