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
