Columbite Ore Concentrate from China
Columbite ore concentrate is a naturally occurring mineral primarily containing niobium (columbium) and tantalum, processed to increase niobium content for extraction. It falls under HTS 2615.90.60.30 as a niobium ore and concentrate used in metallurgical industries for producing niobium metal and alloys. The assay quantity of metal content is reported without deductions per statistical notes.

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)
