DSD/DPD
Activated carbons, of low or high density skeleton, are not classified as dangerous substances under neither EU directive 67/548/EC (Dangerous Substances) nor EU Directive 91/155/EC (Dangerous preparations), including their relevant amendments (respectively 2001/59/EC and 2001/60/EC).

GHS/CLP
With respect to regulation (EC) No. 1272/2008 (CLP) and its amendments, activated carbons with HDS and some activated carbons with LDS is not classified as a dangerous substance.

Some activated carbons with a LDS are classified as follows:

Self-heating substances and mixtures category 2

A self-heating substance or mixture is a liquid or solid substance or mixture, other than a pyrophoric liquid or solid, which, by reaction with air and without energy supply, is liable to self-heat; this substance or mixture differs from a pyrophoric liquid or solid in that it will ignite only when in large amounts (kilograms) and after long periods of time (hours or days).

Some activated carbons are classified as a self-heating substance or mixture of category 2, because in the tests performed in accordance with the test method given in the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part III, sub-section 33.3.1.6; a positive result is obtained in a test using a 100 mm sample cube at 140°C and a negative result is obtained in a test using a 25 mm cube sample at 140°C and the substance or mixture is to be packed in packages with a volume of more than 3 m3.
