Identification of HHPs

The goal of the identification step is to check the registered pesticides against the FAO/WHO criteria for HHPs. Any pesticide meeting one or more of these criteria is considered to be an HHP.

The criteria for identifying HHPs as presented below were defined in 2008 by the FAO/WHO Joint Meeting on Pesticide Management (JMPM).




# Description of HHP Criteria 1 to 8 Explanation
1 Pesticide formulations that meet the criteria of Classes Ia or Ib of the WHO Recommended Classification of Pesticides by Hazard
2 Pesticide active ingredients and their formulations that meet the criteria of carcinogenicity Categories 1A and 1B of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS)
3 Pesticide active ingredients and their formulations that meet the criteria of mutagenicity Categories 1A and 1B of the GHS
4 Pesticide active ingredients and their formulations that meet the criteria of reproductive toxicity Categories 1A and 1B of the GHS
5 Pesticide active ingredients listed by the Stockholm Convention in its Annexes A and B, and those meeting all the criteria in paragraph 1 of annex D of the Convention
6 Pesticide active ingredients and formulations listed by the Rotterdam Convention in its Annex III
7 Pesticides listed under the Montreal Protocol
8 Pesticide active ingredients and formulations that have shown a high incidence of severe or irreversible adverse effects on human health or the environment.


HHP identification tool


Download tool Description and use


(version 20180305, 4.02 MB)

The spreadsheet tool can be used to document the HHP identification process. This can be done for individual pesticides, or for lists of registered pesticides.. Note that the user is responsible for looking up the pesticide properties and classifications from the relevant sources.

How to use:

  • Download the spreadsheet to your PC and open it.
  • Enter your products in either sheet depending on the number of Active Ingredients (A.I.) in the product: "One A.I.(entry)", "Two A.I.s (entry)" or "Three A.I.s (entry)" 
  • Complete the required information for the different criteria, based on data from the dossier or online sources. The spreadsheet will calculate the WHO classification of the formulated product in case only LD50 values of the active ingredients are available.
  • When finished, check the summary pages ("One A.I (summary)" etc. to see which products are marked as HHP.


  • This version of the spreadsheet can hold 5000 products with one A.I., 1000 with two A.I.s and  200 with three A.I.s.
  • File not found warning: if you experience a file not found warning while clicking the link (e.g. in Chrome) then download the file to your  PC first (right-click | Save link as ..) before opening it in MS Excel
