CLP requires some hazard information to be placed on CLP labels for materials with hazards not currently covered under GHS. These hazards are called EUH Statements, although they are not officially part of the CLP-GHS classification.
EUH Statements do not generate any GHS symbols, (with the exception of EUH071, which can generate the corrosive symbol), or GHS P statements. They are more like labelling statements, because they are restricted to the label and labelling part of the SDS. Even on the label, they are placed in the “Supplementary Information” section, rather than being next to the H and P Statements.
There are four types of EUH statement:
- Old Risk Phrases brought in as EUH statements in CLP (note that the old R number is now the EUH number)
- Health hazards not covered under either CLP/GHS or CHIP (EUH070 and EUH071)
- Mixtures containing specific components (or substances containing impurities)
- General information (EUH21o and EUH401)
Current list of EUH Statements: List of EUH Statements to 8th ATP v1.5 20-01-2018.
There is no specific precedence for EUH Statements, although some may be superseded by H Statements, which means that EUH Statements should be derived once the CLP-GHS classification has been obtained.
If more than one EUH Statement which is applicable, then they should all be applied to the supplementary section of the label, and included in Section 2.2 of the SDS (where applicable).
Although EUH Statements are not part of GHS, the EU would like to see them adopted. This has already happened with EUH059, which was adopted into GHS as Hazardous to the ozone layer Category 1, H420, Harms public health and the environment by destroying ozone in the upper atmosphere.
