Comparing published CLP classifications

It is possible to have different published CLP classifications from several sources, including:

• Harmonised Classifications and the REACH dossier
• CLI entries
• CLI entries and Safety Data Sheet classifications from reputable suppliers

The information in these classifications may need to be compared to enable you to take a decision on the classification as a whole.

Normally, Harmonised Classifications are more reliable than REACH registration classifications, which in turn are much more reliable than classifications notified to the Classification and Labelling Inventory.  However, in some cases, this may not be the case, e.g. dodgy REACH dossiers, or where there is a partial Harmonised Classification which needs to be supplemented by REACH dossier classification information, so it is important to treat each substance classification case on its own merits.

To help, we have produced a form to record different published classifications: Classification comparison form .

If you use this form, it should be kept as part of your classification records for at least 10 years after the date of last supply of the substance.
