Import Tips
• 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
