You must keep certain records for introductions of chemicals resulting from non-functionalised surface treatment of listed chemicals, which you’ve categorised as exempted. You must provide these records within 20 working days if we ask for them.
Before you read this page’s content, make sure you’ve already read and understood our record-keeping overview page.
The type of records you must keep depends on whether you know the CAS number, CAS name or, IUPAC name or INCI name.
An introducer is taken to know the CAS number, CAS name or IUPAC name if it would be reasonably practicable for them to find out that number/name.
This means introducers must proactively try to find this information, including checking for it with their chemical supplier.
You will also need the following records:
your chemical isn’t listed on the Inventory with conditions of introduction or use that will be contravened
We'll accept a signed and dated declaration that these checks took place.
*unless it is introduced solely for use in research or analysis and the amount that you introduce in a registration year does not exceed 100kg.
You must have records to demonstrate that your chemical introduction meets the criteria for introductions of chemicals resulting from non-functionalised surface treatment of listed chemicals – see checkboxes below.
You must have records showing all 3 below:
Nanoscale – records to demonstrate one of the following:
Note: For particle size distributions in this range, information only from an SDS/technical data sheet or similar is not enough.
You can use OECD TG 110 to measure particle size and distribution to support that a chemical is not at the nanoscale for particles and fibres with sizes above 250 nm.
OECD TG 125 on Nanomaterial Particle Size and Size Distribution of Nanomaterials measures particles and fibres with a diameter of 1 to 1000 nm and fibres with a length up to 20 µm.
