No harmonised EU classification

Carbon black has no entry in CLP Annex VI — there is no harmonised EU-wide classification for it. That is not evidence of safety. Suppliers remain obliged to self-classify it under CLP, and workplace hazards (dust, asphyxiation, thermal) can exist without a harmonised entry. Always obtain the supplier's SDS for the product you actually use.

Published emergency-response data does exist for carbon black and is reproduced below — first aid, fire fighting and spill response come from US federal sources, not from a harmonised classification.

§ 04 · First-aid measures

Carbon black first aid measures

Call your national emergency number first. These are published first-aid measures, not medical advice, and they do not replace emergency services, a poison control centre or the supplier's safety data sheet.

§4–§6 below reproduce the CAMEO Chemicals entry CARBON BLACK. CAMEO publishes response data per product entry, so the entry can describe a solution, a refrigerated liquid or a molten form rather than the pure substance in §9 — check it matches what you are handling.

Eye: IRRIGATE PROMPTLY - If this chemical contacts the eyes, promptly wash (irrigate) the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention if any discomfort continues.

Breathing: FRESH AIR - If a person breathes large amounts of this chemical, move the exposed person to fresh air at once. Other measures are usually unnecessary.

MSDS vs SDS

Carbon black MSDS vs SDS: is there a difference?

MSDS (Material Safety Data Sheet) is the older name for the same document. In the US, OSHA's Hazard Communication Standard (2012) adopted the GHS-standardised 16-section Safety Data Sheet; in the EU the format is set by REACH Annex II. So a "carbon black MSDS" and a "carbon black SDS" refer to the same document — today it is issued as an SDS. Full breakdown of the differences →

§ 16 · Sources

Reference aid only. This page summarises the harmonised EU classification and computed storage guidance — it is not a Safety Data Sheet and does not replace one. Always verify hazards, handling and storage against the supplier's SDS (sections 7 and 10) and local regulations before use. Page updated 2026-08-11.

Frequently asked questions about carbon black

Is an MSDS the same as an SDS?

In practice, yes. MSDS (Material Safety Data Sheet) is the older name for the same document. In the US, OSHA's Hazard Communication Standard (2012) adopted the GHS-standardised 16-section Safety Data Sheet; in the EU the SDS format is set by REACH Annex II. A document you find labelled "carbon black MSDS" is today issued as an SDS.

Where can I download an official carbon black SDS PDF?

From your own supplier — an SDS is issued per product and supplier, so the correct PDF for an inspection is the one matching the product you actually purchased. The supplier links on this page lead to the official SDS libraries of major distributors.
