Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
Based on the structure of the molecule and taking into account the provisions laid down in Regulation (EC) No 1272/2008 (CLP), as amended for the seventeenth time in Regulation (EU) 2021/849, the test item does not have to be classified with respect to explosiveness.
