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.

Import Tips

Submit production process documentation proving thermal decomposition method

Test for graphitic content (<1% typically) to prevent reclassification

Label bulk shipments clearly as industrial carbon to avoid retail goods scrutiny
