A new practical guide makes clear that inorganic substances with the same chemical composition but different crystalline forms are regarded as different substances under REACH.

Helsinki, 22 June 2010 - The assessment of substance identity is part of the evaluation process carried out by ECHA after registration. The brief advice presented in the Practical Guide explains the approach ECHA will adopt in evaluating the identity of inorganic substances, helping potential
registrants to prepare their registration dossiers.

The Guide will be updated whenever ECHA becomes aware of issues that would benefit from specific, targeted advice of this kind.

Registrants are advised to take note of this Practical Guide when preparing their registrations dossiers to ensure compliance under REACH.
