Proposition 65 - Declaring for Carbon Black under Proposition 65

Question Posed:

What sort of compliance statement or information would we need to provide for carbon black? Note that through our manufacturing processes, once carbon black is incorporated into a rubber compound it becomes bound and is no longer described as “airborne, unbound particles of respirable size”. As such, my understanding is that it does not require a warning label. Is this understanding correct?

Answer Provided:

Carbon Black is listed on the Proposition 65 list as "carbon black (airborne, unbound particles of respirable size)". Therefore you are correct in saying that no declaration is required because you do not have this substance, as listed, in your product.
