Import Tips
• Obtain accurate assay certificates verifying niobium content to comply with statistical reporting requirements without deductions
• Ensure proper documentation of origin from mining sites, as niobium ores often face restrictions on conflict minerals
• Avoid misclassification by confirming the product is ore concentrate, not refined metal (Chapter 81)
