Additional information
Justification for classification or non-classification
Fenpropimorph is classified for acute oral toxicity Cat.4 (H302) according to EC/1272/2008 Annex VI. Despite the fact that one acute inhalation study showed an LC50 of 2.9 mg/l, Fenpropimorph is not classified for acute inhalation toxicity which is in line with the fact that the study has been available at the time the decision on legal classification has been made (study dates 1979, ECB decision has been adopted with the 24th ATP, 1998). In addition to that, there is a newer, GLP conform study available based upon which no classification is needed (key study, BASF 2011).
