REACH Registration as Lead Registrant

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 5 and submit it to ECHA.

The initial cost of being a lead registrant could be daunting considering the high cost of GLP testing(up to 2 million Euros) and dossier preparation. Several companies could form a REACH consortium to pool financial resources. The initial cost could be compensated by offering letter of access to other registrants.

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;
