5. Types of changes and evaluation timeframes
Changes to a biocidal product or biocidal product family authorisation fall into 3 categories:
- administrative – changes that do not result in changes to the risk assessment, efficacy or the physical or chemical properties of the product
- minor – changes that result in limited changes to the risk assessment, efficacy or the physical or chemical properties of the product
- major – changes that cannot be categorised as administrative or minor changes
These are examples of the different categories of change and the approximate timeframes for evaluation:
|Change to the authorisation||Category||Approximate timeframe|
|Change to biocidal product or biocidal product family name.
The new name cannot be identical to a name used for another biocidal product or biocidal product family.
|Transfer of the authorisation to another company established in the UK.||Administrative||30 days|
|Change in the name or address of the authorisation holder.||Administrative||30 days|
|Meeting a post authorisation requirement for storage stability.||Minor||90 days|
|Change in active substance level in formulation.||Major||180 days|
These timeframes are subject to change if the application is suspended for any reason. For example, requesting additional information or data.
