REACH 2018: Are your substances the same?

The European Chemicals Agency (ECHA) says if you are joining an existing SIEF, you need to confirm with the other registrants that your substance is the same as theirs. If your substance has not been registered yet, check with all co-registrants that you intend to register the same substance before forming a SIEF. Further details are available at: Establishing substance sameness
