Classification
4.3 Steps for classifying substances and mixtures
There are five steps for classifying substances and mixtures:
12345
Gather all available information (see below sources of information)
Examine information to make it is adequate and reliable
Evaluate available information against classification criteria
Decide on appropriate classification
Review the classification if needed
4.3.1 Gathering information
The first step when gathering information about a substance is to check Annex VI of CLP to see if there is a harmonised classification.

4.3.2 Examine information to make it is adequate and reliable
The key point here is for the manufacturer or importer to ask themselves whether they have the expertise to make a judgement about whether the hazard information obtained is adequate and reliable for the purpose of classification or whether they need to consult an expert.
4.3.3 Evaluate available information against classification criteria
The manufacturer or importer or the expert, must check if the information gathered reveals a hazardous property.
4.3.4 Decide on appropriate classification
If the evaluation of the hazard information shows that the substance or mixture meets the criteria for classification for a particular hazard, then you must assign the respective hazard class and category and the appropriate labelling elements for the label and/or the SDS, i.e. the signal words, hazard statements, hazard pictograms and precautionary statements
4.3.5 Review the information
The information about classification may need to be changed when new information becomes available.
