Formats and templates


You can download the forms and templates below, to be used in the context of REACH.


If you are a dossier submitter, the harmonised classification and labelling (CLH) template supports you to prepare proposals for CLH.

The template consists of two parts. The first contains:

  • the identity of the substance
  • proposed CLH
  • a history of the previous classification and labelling
  • justification that action is needed at Community level
  • identified uses
  • data sources
  • physicochemical properties of the substance, and
  • the hazard assessment by the dossier submitter

The second part, Annex I, contains:

  • the detailed study summaries of the studies forming the basis of the CLH proposal

Using Annex I is not mandatory, but it can be used to provide more detailed information or confidential information.

  • CLH report template (with explanations)
    (updated 19/04/2023)
  • Template of Annex I to the CLH report (with explanations)
    (updated 31/07/2023)
  • If your substance is a biocidal active substance and you prepare a proposal for CLH under CLP Regulation and a Competent Authority Report (CAR) under Biocidal Products Regulation (BPR) for (re)approval, the common template found under the BPR subsection should be used.
  • If your substance is a plant protection product (PPP) active substance and you prepare a proposal for CLH under CLP Regulation and also an Assessment Report (AR) under PPP Regulation for (re)approval, the common template should be used.
  • In other cases, the CLH report template provided at the top bullet point of the CLP section should be used.




Weight of Evidence/Uncertainty Template

The template and background document for weight of evidence/uncertainty is intended for use in human health and environmental hazard assessments. It can assist to:

  • harmonise the use of weight of evidence and uncertainty assessment within ECHA processes;
  • increase transparency in regulatory decision making (REACH and CLP regulations and the BPR);
  • facilitate the use and integration of alternative methods and all available information in hazard assessment.

The template contains instructions on what is expected under each section. It also provides links to the background document and to other relevant guidance documents.

WHO/IPCS Mode of Action Analysis Framework Templates

The following templates for mode of action analysis are based on the WHO/IPCS Mode of Action Framework and intended for use for both human health and/or environmental mode of action analysis. This framework provides a generic approach to the principles commonly used for evaluating mode of action. It outlines in a structured format the elements to be considered in analyzing whether available data support a particular mode of action.

In order to import the mode of action analysis / human relevance framework in IUCLID related toxicological endpoint summaries, the user imports the template in html format in the corresponding text field in IUCLID available below.
