Products classified under HTS 2804.50.00.10
Amorphous Boron Powder
Amorphous boron powder is a fine, non-crystalline form of elemental boron used in pyrotechnics, metallurgy, and as a dopant in semiconductors. It falls under HTS 2804.50.0010 as pure boron, chemically defined as a nonmetal element in powdered form without compounds or alloys. This classification applies to unworked elemental boron per Chapter 28 notes.
High-Purity Boron Lump
High-purity boron lumps are irregular chunks of elemental boron (>99.9% pure), used in vacuum arc melting for advanced alloys. Falls under HTS 2804.50.0010 as unprocessed boron nonmetal, per Chapter 28 exclusions for worked or alloyed forms.
Elemental Boron for Semiconductor Doping
Elemental boron in powder form specifically for semiconductor doping, supplied undoped and unworked. Classified under HTS 2804.50.0010 as pure nonmetal boron, before any electronic doping per chapter notes.
Boron Powder for Pyrotechnics
Fine boron powder used as a fuel in pyrotechnic compositions for flares and signals. HTS 2804.50.0010 covers this elemental nonmetal in powder form, excluding mixtures or prepared charges (3813).
Ultra-High Purity Boron Pellets
Ultra-high purity (99.999%) boron pellets for research and plasma applications. Elemental boron in pellet form under HTS 2804.50.0010 as chemically defined nonmetal.
Crystalline Boron Rods
Crystalline boron rods are high-purity, solid elemental boron in cylindrical form, used in nuclear applications and high-temperature ceramics. Classified under HTS 2804.50.0010 as unworked boron per chapter provisions for nonmetals in raw forms like rods. Excludes worked or doped variants.
Boron Granules 99.5% Pure
Boron granules are small, irregular particles of high-purity elemental boron (99.5%), utilized in alloy production and chemical synthesis. This product is classified in HTS 2804.50.0010 as boron in granular form, aligning with Chapter 28 for chemically defined nonmetals excluding compounds.
