Mixed Molybdenum Flotation Concentrate
This mixed flotation concentrate combines molybdenite with oxide minerals like wulfenite and powellite, achieving a 45% molybdenum grade from polymetallic deposits. It is not purely roasted molybdenite, so it qualifies as 'other' molybdenum ores and concentrates under tariff item 2613.90.00.

Import Tips & Compliance
• Document the mineral composition and processing steps to confirm it is a flotation concentrate, not a roasted product
• The statistical unit is based on molybdenum metal content, so accurate assay results are essential
• Check for any lead content (from wulfenite) that may require environmental handling declarations

Ferrimolybdite Molybdenum Ore
Ferrimolybdite is a hydrous iron molybdate mineral found in oxidized zones of molybdenum deposits. It is processed into concentrates containing 15-25% molybdenum and is used for hydrometallurgical recovery of molybdenum, falling under tariff item 2613.90.00 as 'other' molybdenum ores and concentrates.
Molybdenite Ore Concentrate
Molybdenite ore concentrate is the primary commercial source of molybdenum, produced by flotation to yield 40-60% molybdenum disulfide. It is classified as 'other' molybdenum ores and concentrates under tariff item 2613.90.00, as it is not roasted or otherwise processed beyond normal metallurgical beneficiation.
Powellite-Bearing Molybdenum Concentrate
Powellite-bearing molybdenum concentrate is derived from skarn deposits, containing 20-30% molybdenum oxide after flotation processing. It is categorized under tariff item 2613.90.00 as 'other' molybdenum ores and concentrates, distinct from common molybdenite products.
Wulfenite Molybdenum Ore
Wulfenite is a lead molybdate mineral processed into low-grade concentrates for molybdenum recovery. It is classified under tariff item 2613.90.00 as 'other' molybdenum ores and concentrates, distinct from molybdenite, and requires specialized processing for extraction.
