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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the concentrate has been roasted
Roasted molybdenum concentrates (calcined) shift to heading 2613.10 due to processing that removes sulfur and alters chemical form.
If containing primarily copper with molybdenum as byproduct
Copper ores and concentrates including molybdenite byproducts are classified under Chapter 26 heading 2603 based on principal metal content.
If derived from industrial slag or residues
Per chapter notes, slag, ash, and residues used for metal extraction fall under heading 2620, not raw ores.

Import Tips & Compliance
• Obtain accurate assay certificates verifying molybdenum content without deductions, as per statistical notes, to ensure proper declaration
• Verify origin certificates to benefit from any preferential tariff treatments under free trade agreements like USMCA
• Avoid misclassification as roasted concentrates (2613.10); test for roasting to prevent customs disputes

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.
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.
