The following information has to be supplied to HSE (the UK Agency) within 120 days of the end of the transition period:

  • Evidence of the registrant’s ECHA registration (e.g. ECHA registration number and date)

  3. information on the manufacture and use of the substance data

  4. an indication as to which of the relevant information on manufacture and use has been reviewed by an assessor  

  5. notification of any ECHA decision which relates to the registration

In order to comply with these requirements there may be an option to upload the latest IUCLID dossier file for the substance.

All other information submitted to ECHA in accordance with Article 10 must be submitted to HSE within 300 days of the end of the transition period plus either 2, 4 or 6 years depending on the tonnage and hazard profile of the substance being registered.

This information will include:
