Unwrought Tantalum, Sintered Bars & Rods, and Powders

Tantalum powder is a loose, particulate form used directly in capacitor manufacturing or pressed into sintered shapes. Unwrought bars and rods obtained simply by sintering are consolidated solid forms that have not been further mechanically worked. The distinction turns on physical form: if the material is free-flowing powder, it classifies under 8103200030; if it has been sintered into a bar or rod shape (even without subsequent working), it falls under 8103200090.

Yes. Tantalum is one of the 'three Ts and gold' minerals covered by SEC conflict-minerals disclosure rules (Section 1502 of Dodd-Frank) for publicly traded companies using it in manufactured products. While the import classification itself does not change, downstream customers — particularly in electronics — may require smelter-of-origin documentation and Responsible Minerals Initiative (RMI) audit certifications. Importers should be prepared to provide chain-of-custody records tracing material back to the smelter.
