(a) if the hazard pictogram ‘GHS01’ applies, the use of the hazard pictograms ‘GHS02’ and ‘GHS03’ shall be optional, except in cases where more than one of these hazard pictograms are compulsory;
(b) if the hazard pictogram ‘GHS06’ applies, the hazard pictogram ‘GHS07’ shall not appear;
(c) if the hazard pictogram ‘GHS05’ applies, the hazard pictogram ‘GHS07’ shall not appear for skin or eye irritation;
(d) if the hazard pictogram ‘GHS08’ applies for respiratory sensitisation, the hazard pictogram ‘GHS07’ shall not appear for skin sensitisation or for skin and eye irritation;
(e) if the hazard pictogram ‘GHS02’ or ‘GHS06’ applies, the use of the hazard pictogram ‘GHS04’ shall be optional.
2.  Where the classification of a substance or mixture would result in more than one hazard pictogram for the same hazard class the label shall include the hazard pictogram corresponding to the most severe hazard category for each hazard class concerned.
For substances that are included in Part 3 of Annex VI and also subject to classification pursuant to Title II, the label shall include the hazard pictogram corresponding to the most severe hazard category for each relevant hazard class.
