Carbon black (CB, CAS 1333-86-4) is a fine, high-surface-area form of elemental carbon produced by partial combustion or thermal decomposition of hydrocarbons. It is used as a reinforcing filler in rubber, including tires, and as a black pigment in inks, coatings and plastics. Its electrical conductivity also makes it a functional additive in conductive compounds.

Frequently Asked Questions
What is carbon black used for?
Carbon black is used as a reinforcing filler in rubber (including tires), as a black pigment in inks, coatings, and plastics, and as a conductive additive that imparts electrical conductivity to compounds. RawSource supplies it in bulk to manufacturers.
Is charcoal the same as carbon black?
No. Carbon black is a fine, high-surface-area form of elemental carbon produced by partial combustion or thermal decomposition of hydrocarbons, whereas charcoal is made by pyrolyzing wood or other biomass. They differ in feedstock, structure, and particle size.
What is another name for carbon black?
Carbon black (CB, CAS 1333-86-4) is sometimes referred to generically as furnace black or by process-specific names; it is elemental carbon, formula C. Grade names denote particle size and surface-area characteristics; see the technical data sheet.
How does carbon black ship under DOT?
The supplied reference (UN1362) corresponds to activated-carbon transport classification; confirm the exact UN/shipping classification for your specific carbon black grade on the CoA and SDS, as it depends on the product form. RawSource provides applicable documentation with each shipment.
What is the cost of bulk carbon black?
Pricing depends on grade (particle size, surface area), packaging (bags, supersacks, bulk), and volume. RawSource quotes industrial quantities; request a bulk quote with your target volume for current pricing.
What is the REACH and TSCA regulatory status of Carbon Black (CB)?
Carbon Black (CB) (CAS 1333-86-4) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 215-609-9).
