How does P363 appear on the label?

The classes and the use of the product decide whether it reaches the label; not all candidates are written, at most 6 statements remain. In the Chemoris selection method, response statements are considered in position 1. If the core statements exceed 6, Article 28(3) allows up to 8; when a combined statement is chosen, its individual parts are not repeated on the label. As P363 is on the list of precautionary statements of Annex IV, it can be used in current labels and SDSs; Chemoris writes it into the document only when the relevant response candidate is selected.
