Tantalite Concentrate Grade A
Tantalite concentrate Grade A is a processed ore with minimum 35% Ta2O5 content, produced by gravity separation and magnetic concentration from primary tantalum deposits. Classified under HTS 2615.90.60.60 as tantalum concentrates, it serves as feedstock for tantalum metal extraction in capacitor production. Statistical reporting requires assay-based metal content.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If columbium (niobium) content predominates
Statistical breaks within heading 2615 prioritize primary metal, shifting to niobium subheading.
If in coarse granular form resembling iron ore mixtures
Coarse particles >4.75mm with mixed metals may classify under iron ores if not predominantly tantalum per statistical note.
If further processed into tantalum pentoxide
Chemical conversion to metal oxides moves it from Chapter 26 ores to Chapter 28 chemicals.

Import Tips & Compliance
• - Submit detailed chemical analysis certificates specifying Ta2O5 percentage to avoid disputes over 'concentrate' status
• - Comply with US Customs columbite-tantalite reporting for Section 1502 Dodd-Frank disclosures on conflict sourcing
• - Common pitfall: Insufficient moisture content adjustment in weight declarations can inflate duties

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.
