Synthetic Tantalum-Niobium Ore Concentrate from China
This is a processed synthetic concentrate containing both tantalum and niobium (columbium) oxides, produced through chemical synthesis or solvent extraction for metal recovery. It falls under HTS 2615.90.30.00 as synthetic concentrates specifically blending tantalum and niobium, distinct from natural ores. Primarily used in the electronics industry for capacitor production.

Import Tips
• Obtain assay certificates verifying tantalum and niobium content as per statistical notes, without deductions, for accurate declaration
• Ensure documentation distinguishes synthetic from natural concentrates to avoid misclassification under 2615.90.10
• Comply with REACH-like regulations for conflict minerals reporting (e.g
• Dodd-Frank) due to tantalum's sourcing risks
