Carbon (Including Carbon Black), N.E.S.

Carbon black — a finely divided form of elemental carbon produced by incomplete combustion — is a critical reinforcing agent in tire manufacturing and rubber goods, making this heading commercially significant to the automotive supply chain. Beyond carbon black, the heading captures other elemental carbon forms not classified elsewhere, such as activated carbon precursors and specialty graphite materials. Importers should be aware that certain carbon black grades from specific origins have been subject to antidumping investigations, making origin documentation and mill certificates essential for compliance.
