Import Tips & Compliance
• 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
