Products classified under HTS 2803.00.00.50
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.
Amorphous Carbon Powder
Pure amorphous carbon powder from various thermal processes, used in metallurgical applications. Classifies under HTS 2803.00.0050 as other carbon forms, explicitly allowed when not graphitic or excluded compounds. Chemically defined inorganic carbon.
Specialty Carbon Black N990
N990 is a large particle, low structure carbon black for non-reinforcing rubber applications. Falls in HTS 2803.00.0050 as other carbon blacks, with specific ASTM grading. Industrial grade per Chapter 28 inorganic definitions.
Vegetable Carbon Black
Vegetable carbon black from pyrolysis of plant materials, used as food coloring E153. HTS 2803.00.0050 includes this pure carbon form when meeting chemical definition. Distinguish from organic colorants.
Furnace Thermal Carbon Black
Furnace thermal carbon black produced in non-oxidizing furnace atmospheres for high purity. Other carbon under HTS 2803.00.0050, used in electronics and toners. Pure form per Chapter notes.
Graphitized Carbon Black
Carbon black heat-treated to develop partial graphitic structure, used in lubricants. Borderline HTS 2803.00.0050 if primarily amorphous, but requires analysis. Chapter 28 notes exclude full graphite.
Lamp Black Ink Pigment
High tinting strength lamp black specifically for gravure ink formulations. HTS 2803.00.0050 as pure carbon pigment form. Industrial bulk per chemical definitions.
Carbon Black Pellets
Densified carbon black pellets for dust-free handling in rubber mixing. Still pure carbon under HTS 2803.00.0050 when uncompounded. Form doesn't affect chemical classification.
High Purity Carbon Black
Ultra-low ash (<0.05%) carbon black for sensitive electronics and pharmaceuticals. HTS 2803.00.0050 other carbon, meeting strict purity for Chapter 28. Trace metal analysis certified.
Industrial Amorphous Carbon
General purpose amorphous carbon from hydrocarbon pyrolysis for foundry applications. Broad HTS 2803.00.0050 classification as residual carbon forms. Bulk industrial per chapter exclusions.
