REACH registrations submitted by UK companies have not been done by 31 December 2020 go through all the steps required to complete the registration, will not be processed further.

The registration process will be terminated if UK companies submitting new registration, any transfer of registrations, or updating an existing registration should be finalized by 31 December 2020

This means in practice that after the transition period:

● All pending UK submissions in REACH-IT will be terminated.

● No registration numbers will be issued to UK companies.

● Companies in the UK cannot perform any actions as duty holders in REACH-IT.

● All registrations held by or returned to UK companies will be revoked gradually in REACH-IT.

The above does not apply to dossiers submitted by companies in Northern Ireland, who have updated their country code in REACH-IT.
