Extra guidance on categorising chemicals at the nanoscale
If you're planning to introduce industrial chemicals (and products that release industrial chemicals) with at least one external dimension in the nanoscale, see our extra guidance on this subject. It'll give you tips to help you work out your introduction category.
Don't forget, your first step to categorisation is to check if your chemical is on our Inventory (a listed introduction). Otherwise, all introducers must work out if their introduction is exempted, reported or assessed.
