ECHA issues guide on reporting substance identity in IUCLID 5

The European Chemicals Agency (ECHA) has published a manual explaining how to structure the substance identification information in IUCLID 5 in accordance with REACH-IT.

The document gives step-by-step directions for specific substance types including:

• Mono-constituent, multi-constituent or unknown, of variable composition, or of biological origin (UVCB) substances
• Multi-constituent substances for which the individual constituents are registered
• Hydrates covered by the registration of the corresponding anhydrous substance
• Well-defined substances for which an acceptable deviation from the naming conventions in the Guidance for identification and naming of substances under REACH is applied
• Isomers
• Substances without a specific EC inventory entry.

The manual explains the systematic verifications REACH-IT applies to ensure information relating to substance identity in the database is coherent.

In addition, technical instructions are given on how to take into account substance identity information specified in pre-registrations or inquiries when creating a joint submission and preparing the registration dossier; and specific considerations relating to the merger or split of pre-SIEFs.
