Which Raw Material Hazard Classification to use when given different options
When a Raw Material has different classifications from different sources, it can be tricky to decide which is the one to choose. There is rarely a standard ‘right’ answer, but here are some data sources to consider.
- Harmonised entry in Annex VI of CLP – https://echa.europa.eu/information-on-chemicals/annex-vi-to-clp This the minimum classification required in the EU; GB started in alignment, but may divert in future
- Supplier data – variable depending on the supplier; also you may have multiple suppliers with different classifications
- IFRA/IOFI Labelling Manual – expert reviewed data available to members, however, it may not be the same grade as you purchase
- ECHA – data from the CLP notification/REACH registration process – https://echa.europa.eu/information-on-chemicals
Remember that a CAS number may represent different grades/types of Item, that may have different classifications e.g. orange peel oil, orange flower oil
