Lampblack Carbon Black
Lampblack is a type of amorphous carbon produced by the incomplete combustion of oils or resins, resulting in fine black soot. It falls under HTS 2803.00.0050 as 'other' forms of carbon, specifically carbon blacks not classified elsewhere in heading 2803. Primarily used as a pigment in inks and paints.
Acetylene Black
Acetylene black is a highly conductive form of carbon black produced by thermal decomposition of acetylene gas. Classified under HTS 2803.00.0050 as other carbon blacks, it's valued for electrical conductivity in batteries and electrodes. Meets Chapter 28 definition for chemically defined carbon compounds.
Thermal Black Carbon
Thermal black is carbon black made by thermal decomposition of hydrocarbons in the absence of air, yielding larger particle sizes. It qualifies for HTS 2803.00.0050 as other carbon not elsewhere specified, used mainly in rubber reinforcement. Excluded from graphite classifications per Chapter 28 notes.
Channel Black Pigment
Channel black, an older production method carbon black from oil flame impingement on channel irons, provides high structure for specialty inks. Falls under HTS 2803.00.0050 as other carbon blacks, distinguished by manufacturing process. Pure amorphous carbon per Chapter 28 chemical definitions.
Bone Black Charcoal
Bone black, also called bone char, is amorphous carbon derived from calcined animal bones, used for decolorizing sugar. Classified in HTS 2803.00.0050 as other forms of carbon, specifically non-graphitic charcoal forms allowed in Chapter 28. Chemically defined per subchapter notes.
Gas Black Carbon
Gas black carbon results from natural gas decomposition, offering medium structure for plastic colorants. HTS 2803.00.0050 covers this as other carbon black variants not principal use specified. Remains inorganic per Chapter exclusions.
