Is your substance not registered yet?
For each substance you have pre-registered, a pre-SIEF page was set up in REACH-IT.
In the pre-SIEF page, you will find the contact information of the other companies that have pre-registered with the same substance identifier. You need to contact each other to see who will register and if your substances are the same. Once you establish that you have the same substance, you have formed a substance information exchange forum (SIEF).
In the SIEF, you will share the data you have on your substance with your co-registrants, share costs and prepare the joint registration.
