High-Purity Tantalum Granules
Tantalum granules (1-5mm irregular shapes) produced by gas atomization, used in capacitor manufacturing and powder metallurgy. This unwrought form fits HTS 8103.20.00.90 as 'other' tantalum powders and granules, excluding sintered rods. Granules are considered powder equivalents in unwrought state.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in bars or rods simply sintered
Sintered tantalum forms consolidated into bars/rods move to the sintered subheading, not loose granules.
If derived from ore processing residues
Tantalum-bearing concentrates or intermediate powders from mining classify under Chapter 26 slag/ash.
If ferro-tantalum alloy
Ferrous alloys containing tantalum fall under Chapter 72 iron/steel ferroalloys.

Import Tips & Compliance
• Submit granulometry report (sieve analysis) to prove unwrought status versus sintered bars
• Ensure vacuum-sealed packaging; exposure to air can cause reclassification if oxidized
• Cross-check with CBP for 'powder' definition; granules under 10mm typically qualify
