Products classified under HTS 2803.00.00
Furnace Black Carbon Black
Furnace black is a type of carbon black produced in a furnace by partial combustion of hydrocarbons, resulting in fine particulate carbon with high surface area. It falls under HTS 2803.00.00 as a form of carbon black not elsewhere specified, used primarily as a reinforcing filler in rubber products like tires.
Thermal Black Carbon Black
Thermal black carbon black is manufactured by thermal decomposition of hydrocarbons in the absence of air, yielding a coarser particle size than furnace black. Classified in HTS 2803.00.00 as other forms of carbon black, it's used in plastics and as a pigment in inks.
Acetylene Black Carbon Black
Acetylene black is produced by thermal decomposition of acetylene gas, resulting in highly structured carbon particles with excellent conductivity. It is classified under HTS 2803.00.00 as a specialized carbon black used in batteries and conductive plastics.
Channel Black Carbon Black
Channel black carbon black is made by impinging hydrocarbon flames against iron channels, producing high-color fine particles. It qualifies under HTS 2803.00.00 for pure carbon blacks used in inks and high-quality pigments.
Graphitized Carbon Black Powder
Graphitized carbon black undergoes heat treatment to develop partial graphitic structure while remaining primarily amorphous carbon. Classified in HTS 2803.00.00 as other forms of carbon, excluding artificial graphite, for use in specialty rubbers.
Colloidal Carbon Dispersion Base
Pure colloidal carbon powder intended for aqueous or solvent dispersions, with particle size <1 micron for stable suspensions. Falls under HTS 2803.00.00 as chemically defined carbon not elsewhere specified.
Amorphous Carbon Powder (Industrial Grade)
Industrial-grade amorphous carbon powder from thermal cracking processes, used as reductant in metallurgy. HTS 2803.00.00 includes such non-specified carbon forms excluding chapter exclusions.
Vulcan Carbon Black (Tire Grade N330)
N330 grade carbon black, known as Vulcan, is a reinforcing furnace black for tire treads with balanced processing characteristics. Classified under HTS 2803.00.00 as standard carbon black for rubber reinforcement.
Conductex Carbon Black (Conductive Grade)
Conductex is a high-structure carbon black designed for electrical conductivity in compounds and batteries. HTS 2803.00.00 covers pure conductive carbon blacks.
Lampblack Carbon Pigment
Lampblack is a traditional form of amorphous carbon produced by burning oil or pitch in limited oxygen, used as a dense black pigment. HTS 2803.00.00 covers it as other forms of carbon not specified elsewhere, distinct from channel or furnace blacks.
