Roasted Molybdenite Concentrate
Roasted molybdenite concentrate is produced by calcining molybdenum sulfide ore to convert MoS2 into MoO3, removing sulfur as SO2. It falls under HTS 2613.10.00.00 as roasted molybdenum ores and concentrates, used primarily for extracting technical-grade molybdic oxide.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing less than 3% molybdenum by weight
Low-grade residues or slags from molybdenum processing fall under other metal ores and concentrates.
If chemically purified to molybdates or acids
Purified chemical compounds of molybdenum are classified as inorganic chemicals, not ores.
If classified as slag or ash from roasting used for metal recovery
Industrial slags and residues for metal extraction are under heading 2620 per chapter notes.

Import Tips & Compliance
• Obtain a commercial invoice specifying assay molybdenum content (Mo percentage) as per statistical notes for accurate duty assessment
• Ensure Certificate of Analysis (COA) from a certified lab verifies roasting process and metal purity to avoid reclassification
• Declare exact weight of molybdenum content without deductions; common pitfall is underreporting assay leading to penalties
