THE WHO RECOMMENDED CLASSIFICATION OF PESTICIDES BY HAZARD
AND GUIDELINES TO CLASSIFICATION 2009
The WHO Recommended Classification of Pesticides by Hazard was approved by the
28th World Health Assembly in 1975 and has since gained wide acceptance. When it was
published in the WHO Chronicle, 29, 397-401 (1975), an annex, which was not part of the
Classification, illustrated its use by listing examples of classification of some pesticidal active
ingredients and their formulations. Later suggestions were made by Member States and
pesticide registration authorities that further guidance should be given on the classification
of individual pesticides. Guidelines were first issued in 1978, and have since been revised
and reissued every few years.
Up until the present revision the original guidelines approved by the World Health Assembly
in 1975 have been followed without amendment. In December, 2002 the United Nations
Committee of Experts on the Transport of Dangerous Goods and on the Globally Harmonized
System of Classification and Labelling of Chemicals (UNCETDG/GHS) approved a document
called “The
Globally Harmonized System of Classification and Labelling of Chemicals”
with the intent to provide a globally-harmonized system
1
(GHS) to address classification of
chemicals, labels, and safety data sheets. The GHS (with subsequent revisions) is now being
widely used for the classification and labeling of chemicals worldwide. For this revision of
the Classification the WHO Hazard Classes have been aligned in an appropriate way with
the GHS Acute Toxicity Hazard Categories for acute oral or dermal toxicity as the starting
point for allocating pesticides to a WHO Hazard Class (with adjustments for individual
pesticides where required). It is anticipated that few of the more toxic pesticides will change
WHO Hazard Class as a result of this change. As has always been the case, the classification
of some pesticides has been adjusted to take account of severe hazards to health other than
acute toxicity (as described in Part II). The GHS Acute Toxicity Hazard Category for each
pesticide is now presented alongside the existing information.
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.
The toxicity values are intended to be a guide only. Formulations should be separately
classified using the methods set out on pages 4 (single technical product) and 7 (mixtures)
and the table in Part I. To assist in the classification of formulations, an annex is provided
giving numerical tables from which the classification may also be derived.

Comments on Part II of the document are welcome, together with proposals for new entries.
These should be addressed to the International Programme on Chemical Safety, World
Health Organization, 1211 Geneva 27, Switzerland, and should include supporting data on
the compound being commented on or proposed.
This document is a revision of the document previously issued as ISBN 92 4 154663 8.
