7	Reproductive toxicity	Category 2	Warning	H361	P308+P313 P201 P202 P280 P405 P501	[Rationale for the Classification] Based on (1), since external or visceral malformations were observed in fetuses at the dose where maternal toxicity was observed, it was classified in Category 2. Besides, the classification result was changed from the previous classification by the use of new information sources. [Evidence Data] (1) In a developmental toxicity test in which female rabbits were dosed by gavage on gestational days 7-19, decreased body weight, external and visceral abnormalities were observed in fetuses at the dose where maternal toxicity (decreased body weight gain, decreased feed consumption) was observed (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2014)). Besides, in JMPR (2014), it is reported that an increased number of total resorptions, increased post-implantation loss, and increased incidences of external, visceral and skeletal malformations (open eyes, major fusion of sternebrae, cleft palate, etc.) were observed in embryos/fetuses (JMPR (2014)). [Reference Data, etc.] (2) In a two-generation reproduction toxicity study with rats by feeding, though decreased body weight gain and decreased food consumption were observed in parental animals, and decreased body weight gain was observed in pups, no effects on fertility were observed (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2014), EPA Pesticide (1998)). Besides, it is reported in JMPR (2014) that a decreased number of implantations was observed in F1 maternal animals as effects on fertility (JMPR (2014)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
8	Specific target organ toxicity - Single exposure	Not classified	- -	-	-	[Rationale for the Classification] There are no reports of single exposure to this substance in humans. As for experimental animals, based on (1)-(3), no findings which would enable the identification of target organs were obtained from tests through any of the oral, dermal, and inhalation routes. Therefore, it was classified as "Not classified." The classification result was changed from the previous classification by the use of new information sources. [Evidence Data] (1) In a single oral dose test with rats, hypolocomotion, ptosis, salivation, irregular respiration, piloerection and abnormal gait were observed at or above 2,253 mg/kg (exceeding Category 2). In addition, reddish tear, hematuria, sedation and declined body temperature were observed in high-dose groups (though there was no description of doses, it was considered to be 5,500 mg/kg, the highest dose, and 4,400 mg/kg, one step below that). Deaths were observed from 3,520 mg/kg. As necropsy findings, discoloring of the liver, gastric distention, reddish-darkening and atrophy of the thymus, and discoloring of the kidney, etc. were observed only in dead animals (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2014), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2013)). (2) In a single dermal administration test with rabbits, at 2,000 mg/kg (upper limit of Category 2), there were neither findings of effects nor deaths related to treatment, and also, no abnormality was observed in necropsy findings (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2014), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2013)). (3) In a 4-hour single inhalation exposure test with rats, salivation and hypolocomotion were observed after exposure to the dust of this substance at 3.2 mg/L (corresponding to Category 2, described that it was the highest reachable concentration as the dust). However, there were no deaths, and also no striking changes observed in macroscopic pathology (A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2015)).

9	Specific target organ toxicity - Repeated exposure	Category 1 (blood system, liver), Category 2 (kidney)	Danger Warning	H372 H373	P260 P264 P270 P314 P501	[Rationale for the Classification] Based on (1)-(3), in oral administration to rats and mice, effects on the liver and kidney were observed within the range of Category 2. Based on (4) and (5), in oral administration to dogs, effects on the blood system and liver were observed within the range of Category 1. Therefore, it was classified in Category 1 (blood system, liver), Category 2 (kidney). The previous classification was changed by the use of new information sources. [Evidence Data] (1) As a result of administration to rats by feeding for 90 days, hepatocyte hypertrophy, etc. were observed at or above 140 ppm (male: 10.2 mg/kg/day, female: 13.4 mg/kg/day, within the range of Category 2). At 480 ppm (male: 34.5 mg/kg/day, female: 41.3 mg/kg/day, within the range of Category 2), increased eosinophilic body and hyaline droplet degeneration in the renal tubular epithelial cells, etc. in males and increased reticulocytes, etc. in females were observed (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2014)). (2) As a result of administration to mice by feeding for 13 weeks, at or above 625 ppm (95 mg/kg/day, within the range of Category 2), hepatocyte hypertrophy was observed in both sexes, and pyelonephritis, etc. were observed in males (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2014), JMPR (2014), EPA Pesticide (1998)). (3) As a result of a combined repeated toxicity test with the carcinogenicity test with rats for 2 years, increased weight of the liver, an increased incidence of chronic nephropathy, etc. were observed in both sexes at or above 400 ppm (male/female: 29.0/26.3 mg/kg/day, within the range of Category 2), and decreased values of hemoglobin and hematocrit. etc. were observed at 3,200 ppm (male/female: 241/248 mg/kg/day, exceeding Category 2) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2014), JMPR (2014)). (4) As a result of a 1-year chronic toxicity test (oral administration of capsules) with dogs, decreased hemoglobin and erythrocyte counts, increased weight of the liver, hepatocyte hypertrophy, etc. were observed at or above 6 mg/kg/day (within the range of Category 1), and increased weight of the thyroid and kidney, adrenal cortex vacuolation, decreased weight of the uterus and thymus (females), etc. were observed at 36 mg/kg (within the range of Category 2) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2014), JMPR (2014)). (5) As a result of a 2-year chronic toxicity test (feeding) with dogs, hepatocyte hypertrophy with glycogen storage and slight inflammation in the liver, and increased weight of the liver and thyroid, etc. were observed at 350 ppm (converted guidance value: 9.0 mg/kg/day, within the range of Category 1) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2014), JMPR (2014)).
