GB classification and labelling
Classifying and labelling substances and mixtures placed on the GB market
Substances and mixtures placed on the GB market must be classified and labelled in line with the GB CLP Regulation.
There are 2 kinds of classification:
- mandatory classification
- self-classification
Mandatory classification
Mandatory classification is a classification that has been made legally binding within Great Britain. It is equivalent to the 'harmonised classifications' that exist under EU CLP.
The mandatory classifications and the accompanying hazard labelling (MCL) are shown on the GB mandatory classification and labelling list (GB MCL list).
Where a substance has an MCL for some or all hazard classes, suppliers to the GB market must apply it.
The GB mandatory classification and labelling system is hosted, managed and operated by HSE (as the GB CLP Agency).
Self-classification
Self-classification is where the supplier gathers and evaluates all of the available information, then compares it to the classification criteria.
Self-classification applies to all mixtures, and to substances which do not have a mandatory classification.
Substances which do have a mandatory classification must be self-classified for any hazard classes not covered by that mandatory classification.
