Subheadings
Products classified under Tariff item 26.13
Calcined Molybdenum Ore Pellets
Pelletized roasted molybdenum ore, produced by oxidative roasting of molybdenite to yield a MoO3-rich material. The pellets are a roasted concentrate form, fitting the tariff item for roasted molybdenum ores and concentrates.
2613.10.00High-Grade Roasted Molybdenum Concentrate Briquettes
Briquetted roasted molybdenite concentrate with over 50% molybdenum content, processed for easier handling. The briquetting does not alter the roasted nature, so it remains a roasted molybdenum concentrate under this item.
2613.10.00Purified Roasted Molybdenum Concentrate Powder
Fine powder from roasted and partially purified molybdenum concentrate, with molybdenum content between 55-65%. The roasting step qualifies it as a roasted concentrate, even if further purified, as long as it is not subjected to processes beyond normal metallurgical practices.
2613.10.00Roasted Copper-Molybdenite Flotation Concentrate
Flotation byproduct from copper ores, roasted to recover molybdenum as MoO3-rich material. This roasted concentrate is typical from porphyry deposits and falls under this item as a roasted molybdenum concentrate.
2613.10.00Roasted Molybdenite Concentrate
Roasted molybdenite concentrate produced by calcining molybdenum sulfide ore to convert MoS2 into MoO3, removing sulfur as SO2. This is the standard roasted form used primarily in steelmaking and falls directly under this tariff item.
2613.10.00Roasted Molybdenum Ore from Climax Mine
Roasted molybdenum concentrates sourced from Climax-type deposits, rich in molybdenite and prized for low impurities in steelmaking. The source does not affect classification; the roasted form qualifies under this item.
2613.10.00Roasted Molybdenum-Wolframite Mixed Concentrate
Roasted concentrate blending molybdenite and wolframite, roasted to volatilize impurities. Since molybdenum is the principal metal, it falls under this item as a roasted molybdenum concentrate, even with tungsten content.
2613.10.00Technical Molybdic Oxide from Roasted Ore
Technical molybdic oxide produced from roasting molybdenum concentrates, containing 99%+ MoO3. This is the primary product of roasting and falls under this item as a roasted molybdenum concentrate, before final purification.
2613.90.00Ferrimolybdite Molybdenum Ore
Ferrimolybdite is a hydrous iron molybdate mineral found in oxidized zones of molybdenum deposits. This ore is processed to extract molybdenum and falls under tariff item 2613.90.00 as an 'other' molybdenum ore, distinct from the more common molybdenite concentrates.
2613.90.00Mixed Molybdenum Flotation Concentrate
This flotation concentrate blends molybdenite and oxide minerals like wulfenite and powellite, achieving a 45% molybdenum grade. It is classified under tariff item 2613.90.00 as an 'other' molybdenum concentrate, as it is not a purely roasted molybdenite product.
2613.90.00Molybdenite Ore Concentrate
Molybdenite ore concentrate, containing 40-60% molybdenum disulfide, is the primary commercial source of molybdenum. It is produced by flotation from mined ore and falls under tariff item 2613.90.00 as an 'other' molybdenum concentrate, not being a roasted product.
2613.90.00Powellite-Bearing Molybdenum Concentrate
Powellite-bearing molybdenum concentrate, derived from skarn deposits, contains 20-30% molybdenum oxide and is processed via flotation. It is classified under tariff item 2613.90.00 as an 'other' molybdenum concentrate, distinct from common molybdenite products.
2613.90.00Wulfenite Molybdenum Ore
Wulfenite is a lead molybdate mineral processed into low-grade concentrates for molybdenum recovery. It falls under tariff item 2613.90.00 as an 'other' molybdenum ore, requiring specialized processing to extract molybdenum.
