Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the concentrate is primarily tantalum rather than niobium
Tantalum ores and concentrates are classified under heading 26.15, which covers niobium and tantalum ores, but the subheading depends on the dominant metal.

Import Tips & Compliance
• Verify the concentrate is not a tantalum ore, as that may be classified separately; if mixed, 2617.90.00 applies
• Declare the niobium metal content in kilograms per statistical note 1
• Ensure the processing history is limited to metallurgical industry norms to avoid exclusion under Chapter Note 2
