Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the concentrate is not roasted
Unroasted copper-molybdenite concentrates are classified under the other tariff item.
If the copper content is the primary value
Copper ores and concentrates are classified under heading 26.03 when copper is the main metal.

Import Tips & Compliance
• Ensure the concentrate is primarily valued for its molybdenum content, not copper, to justify classification under this item
• Provide assay results showing Mo and Cu percentages
• Be prepared to demonstrate that the roasting process is standard for molybdenum recovery
