Which substances do I have to notify to the Inventory?

The obligation to notify to the Classification & Labelling Inventory includes:
a) All Substances (Classified and Not Classified) subject to Registration in accordance with Regulation(EC) No 1907/2006.
b) Substances which meet the criteria for classification as hazardous and are placed on the market
either on their own or in a mixture above the concentration limits specified in Appendix 1 of this
briefing, which results in the classification of the mixture as hazardous.

Note that you must notify a substance even if its classification and labelling is (completely) harmonised and it is listed in Part 3 of Annex VI to the CLP Regulation.

However, the obligation to notify does not apply to a number of substances and mixtures in the finished state and intended for the final user, or for uses for which there is specific legislation in place, e.g. radioactive materials, medicinal products, cosmetic products and food and feeding stuffs.
