The document is arranged as follows:

  • Part I: Overarching principles for the classification of pesticides as recommended by the World Health Assembly. These principles continue to apply, but the World Health Assembly Resolution envisaged that the classification criteria might need to be developed with time and increasing experience. The guide-points originally proposed in 1975 are now being aligned with the corresponding Acute Toxicity Hazard Categories from the GHS.
  • Part II: Guidelines to Classification. Individual products are classified in a series of tables, according to the oral or dermal toxicity of the technical product. The tables are subject to review periodically.
