Acetylene Black Carbon Black from Japan

Acetylene black is produced by thermal decomposition of acetylene gas, creating high-purity carbon black with excellent electrical conductivity. It is classified under HTS 2803.00.0010 as a form of carbon black, primarily used in dry cell batteries and conductive polymers. Its unique chain-like structure provides superior performance in electrical applications.

Import Tips

Include production process documentation proving acetylene decomposition to validate as pure carbon black under Chapter 28

Electrical resistivity test results help CBP confirm battery-grade purity vs. pigment grades

Avoid packaging with conductive additives; pure form only qualifies for 2803
