Coltan Ore (Tantalite)

Coltan ore, primarily tantalite, is a natural mineral deposit containing tantalum niobate (FeTa2O6) extracted from alluvial or hard-rock mining operations in regions like the Democratic Republic of Congo. It falls under HTS 2615.90.60.60 as tantalum-bearing ore and concentrates, distinguished by its high tantalum content used in electronics manufacturing. The assay quantity of metal content is reported without deductions per statistical notes.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2615.90.30.00Same rate: 25%

If primarily niobium (columbium) content exceeds tantalum

Ores dominated by niobium fall under the specific niobium subheading within the same heading 2615.

2617.10.00Lower: Free vs 25%

If chemically processed into slag or residues for metal extraction

Processed residues from tantalum extraction used industrially classify under heading 2620 per chapter notes, not raw ores.

2846.90.80Lower: 3.7% vs 25%

If refined to high-purity chemical compounds rather than ore

Purified tantalum compounds like tantalum oxide shift to Chapter 28 for inorganic chemicals.

Import Tips & Compliance

- Verify tantalum content via certified assay reports to confirm classification under 2615.90.60.60 and report exact metal quantity without deductions

- Obtain origin certificates due to conflict mineral regulations (Dodd-Frank Act) requiring due diligence for coltan from Central Africa

- Beware of misdeclaration as niobium ore; improper blending can lead to reclassification and penalties
