On the May 28, 2021, the European Commission released the 17th Adaptation to Technical Progress (ATP) to the Classification, Labeling and Packaging (CLP) Regulation. The ATP is another update to the CLP Annex VI Harmonised Chemical Classification List. Due to the need to allow suppliers time to update their products, and to sell any existing stocks that have already been labeled, the regulation will apply starting Dec. 17, 2022.

Most of the updates were submitted to the European Chemicals Agency (ECHA) and then assessed by the Committee for Risk Assessment of the Agency. After taking into account comments from interested third parties, an opinion is put forward for ratification by the European Commission. 

This latest update includes 22 new entries, 39 updated entries and one classification deletion. Within these are the common substances citric acid, boric acid and d-limonene, and particular attention has been paid to the inclusion of specific acute toxicity estimate values and multiplying factors.

You will need to check to see if any of the substances listed in the 17th ATP are present in your products before reclassifying and relabeling any affected products prior to the December 2022 application date. You may also need to update your Safety Data Sheets accordingly.
