REACH Registration as Lead Registrant

from CIRS by


Joint Registration and Lead Registrant

Each registrant is obliged to submit a registration dossier for each of his substances. In cases where the same substance is manufactured or imported or intended to be manufactured or imported by more than one company, all the registrants are obliged to be part of the same joint submission for that substance. The joint submission obligation applies for both the registration of phase-in substances and for that of non-phase-in substances.

Registrants are required to jointly submit information on the intrinsic properties of the substance (studies and testing proposals, if any) and its classification and labelling. Registrants may decide to jointly submit the guidance on safe use of the substance, the chemical safety report (CSR) and an indication of what information submitted for the CSR has been reviewed by an assessor.

The information that needs to be submitted jointly is submitted by one lead registrant on behalf of the other registrants. Other information needs to be submitted by all registrants individually.

If a substance is of strategic importance to your company and no other lead registrant or REACH consortium is in place, or if you hold valid data for the REACH registration of the substance, you should consider registering the substance as lead registrant. As a lead registrant, you will be required to prepare a complete registration dossier (technical dossier + chemical safety report) in IUCLID 6 and submit it to ECHA.

REACH Registration: What information is required?

A registration dossier consists of two parts: Technical Dossier and Chemical Safety Report.

1. Technical Dossier (> 1 ton per year)

  • Identity of manufacturer/importer;
  • Identity, volume and identified uses of substance;
  • Classification and labeling ;
  • Study report and robust study summaries according to Annex VII to X (physiochemical, toxicological, eco-toxicological properties, etc);
  • Testing proposal;
  • Statement whether tests have been carried out on vertebrate animals;

2. Chemical Safety Report (> 10 ton per year)

  • Human hazard assessment, physicochemical properties assessment, environmental hazard assessment and PBT/vPvB assessment;
  • Exposure Scenario is required if classified as dangerous or PBT/vPvB;
    • operational conditions and risk management measures for each use;
    • exposure estimation;
