Furnace Black Carbon Black
Furnace black is a type of carbon black produced by the incomplete combustion of heavy petroleum products in a furnace, resulting in finely divided amorphous carbon particles. It falls under HTS 2803.00.0010 as a chemically defined form of carbon black used primarily as a reinforcing filler in rubber products like tires. This high-surface-area pigment provides strength and abrasion resistance.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-dispersed in non-aqueous media for paints
Dispersion preparations of carbon black for paints/inks fall under heading 3812, not pure carbon black.
If chemically treated or surface-modified for specific uses
Surface-modified carbon blacks with chemical treatments are classified as prepared chemical additives in 3824.
If in colloidal graphite form
Colloidal or semi-colloidal graphite is specifically excluded and classified under artificial graphite in 3801.

Import Tips & Compliance
• Verify purity and particle size specs via Certificate of Analysis to confirm classification as carbon black under Chapter 28, avoiding misclassification as pigments
• Include Safety Data Sheets (SDS) documenting non-hazardous amorphous carbon status; bulk shipments require proper dust control labeling
