Making changes to the CLP Regulation – ATPs
Like its predecessor Directives, the CLP Regulation is routinely updated to take account of scientific knowledge about chemicals and technical development. These amendments are known as adaptations to technical progress or ATPs.
In general there are two series of ATPs which run side-by-side:
- proposed new harmonised substance classifications – these are independently assessed and, if agreed, will amend the list of entries in Annex VI to CLP. Expected to be every 12 months or so; and
- amendments made to the classification criteria and technical annexes to the GHS:
- These amendments reflect the biennial rhythm of the UN GHS, and need to be incorporated into CLP so would be expected every 2 years.
- These amendments may also align GHS more closely to the transport regulations.
The ATPs are voted on by Member States and, if agreed, are published as European Commission Regulations.
