Tantalum Powder 99.9% Pure
High-purity tantalum powder (99.9% Ta) used in electronics and additive manufacturing, supplied in unwrought form as fine particles less than 100 microns. It falls under HTS 8103.20.00.90 as unwrought tantalum powder, distinct from sintered powders or wrought forms. This classification covers tantalum powders not further processed into bars or rods.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in the form of waste or scrap
Tantalum waste or scrap, even if powdered, shifts to 8103.30 as it represents residues from manufacturing rather than virgin unwrought material.
If obtained simply by sintering
Powders processed via sintering into bars or rods fall under the specific sintered subheading, excluding pure powders.
If chemically defined and alloyed with >1% other elements
Alloyed tantalum powders may classify as chemical preparations if not predominantly tantalum, per Chapter 38 notes on metal alloys.

Import Tips & Compliance
• Verify purity certificate (e.g
• 99.9% Ta) via spectrometry analysis to confirm unwrought powder classification and avoid reclassification as waste
• Include material safety data sheets (MSDS) for fine powders due to flammability risks; ensure packaging prevents oxidation
• Declare exact particle size distribution to distinguish from sintered powders, preventing customs disputes
