Carbon Black and Other Forms of Carbon (NESOI)

Yes, carbon black has been subject to antidumping duty investigations and orders from various countries at different times. Importers should check the current scope of any active orders with CBP and the International Trade Commission before sourcing, as duty liability can be substantial and retroactive if a scope ruling covers the imported product.

Carbon black is a furnace-process or channel-process product consisting of fine amorphous carbon particles produced by incomplete combustion or thermal decomposition of hydrocarbons. Other forms of carbon NESOI include acetylene black, lamp black, and specialty graphitic or activated carbons not elsewhere classified. The distinction matters because end-use specifications, pricing, and trade-remedy exposure differ significantly between the two lines.
