Manuals on preparing REACH and CLP dossiers
The aim of the manuals on How to prepare REACH and CLP dossiers is to help companies to prepare, create and update IUCLID dossiers.
The manuals highlight the IUCLID sections that must be completed for the different dossier types, to prepare a valid and complete dossier that can be submitted to ECHA through REACH-IT. These manuals are also integrated in IUCLID.
Step-by-step instructions for completing the different IUCLID sections and processing each submission are provided in the manuals alongside overviews of the processes and legal concepts involved.
These manuals replace the former Data Submission Manuals (DSMs).

ECHA performs a completeness check on each incoming registration to ensure that the required information is provided. This check includes a manual verification of certain elements that cannot be checked automatically. You can find further information on this document:
Dissemination and confidentiality under the REACH Regulation
This manual helps companies who are preparing registration dossiers to understand the dissemination process, what information will be made publicly available on ECHA's website, how to make a confidentiality request, how to prepare a justification and the basic procedure that ECHA follows to assess such requests.
In addition, this document advises industry on how to derive a public name for a substance for which the IUPAC name is requested confidential.
Technical document to support registrants on transition to new IT tools
This document provides a source of information for registrants with existing data in IUCLID 5 format who need to adapt and prepare their information for submission with the new IUCLID and REACH-IT versions.
This is a technical background document. Support on how to prepare a complete and compliant dossier in the IUCLID 6 format is available in the other manuals above.
The system-to-system (S2S) service supports companies in preparing and submitting poison centre or hazardous chemicals in products (SCIP) notifications in an automated way.
With the S2S service, companies can create a poison centre or SCIP notification dossier in their own systems, using harmonised IUCLID formats. An automatic S2S transfer then allows companies to submit notifications directly from their system to the ECHA submission portal.
Companies can test the s2s service before using it via a dedicated test portal after accepting its terms and conditions. Companies using the S2S service can also perform a connectivity, security and submission test in test mode.
Companies that want to use the S2S service can request access using the ECHA contact form.
