4	Skin sensitization	Classification not possible	- -	-	-	[Rationale for the Classification] Based on (1)-(4), since there is a mixture of positive and negative results, it was classified as "Classification not possible." [Reference Data, etc.] (1) It is reported to be positive with a positive rate of 30% in a skin sensitization test (split adjuvant method) with guinea pigs (JMPR (2005)). (2) It is reported to be negative in skin sensitization tests (Buhler method, maximization method) with guinea pigs (JMPR (2005)).

FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
5	Germ cell mutagenicity	Not classified	- -	-	-	[Rationale for the Classification] Based on (1) and (2), since the results of all standard combination tests, including in vivo and in vitro tests, were negative, it was classified as "Not classified." [Evidence Data] (1) As for in vivo, it was negative in a bone marrow micronucleus test with mice (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2015)). (2) As for in vitro, it was negative in a bacterial reverse mutation test, a mouse lymphoma TK test, and a chromosome aberration test and an unscheduled DNA synthesis test with cultured mammalian cells (EPA Pesticide (1994), IARC 12 (1976), EHC 64 (1986), Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2015)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
6	Carcinogenicity	Category 2	Warning	H351	P308+P313 P201 P202 P280 P405 P501	[Rationale for the Classification] Based on (1), the newest classification by other organizations was the EU CLP classification, which is equivalent to Category 2. Based on (2) and (3), carcinogenicity was observed in rats, therefore, it was classified in Category 2. [Evidence Data] (1) In classification results by domestic and international organizations, it was classified as Group 3 by IARC (IARC Suppl.7 (1987)), as group E (evidence of non-carcinogenicity for humans) by EPA OPP RED (Office of Pesticide Programs, Registration Eligibility Decision (1994)), and as Carc.2 by EU CLP (EU CLP classification (Access on May 2019)). (2) In a carcinogenicity study by 2-year administration of this substance (30, 100, 500, 1,000 mg/kg/day) by feeding to rats, the incidence of Leydig cell tumors increased in males at 1,000 mg/kg group. Since the SD strain used in this study did not develop Leydig cell tumors frequently, the increase observed in the 1,000 mg/kg group was judged to be administration-related (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2015)). (3) In a carcinogenicity study by 18-month administration of this substance by diet to mice, no increased incidence of neoplastic lesions was observed after administration of this substance (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2015)). [Reference Data, etc.] (4) Regarding the increased incidence of the Leydig cell tumors in male rats, the Food Safety Commission judged that it was impossible to deny that this substance was a carcinogen with a threshold based on existing findings (genetic toxicity and carcinogenicity) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2015)). On the other hand, although the EU assigned it a harmonized classification as Carc. 2 based on the increased incidence of Leydig cell tumors observed in a carcinogenicity study with rats, the possibility that the mechanism of the tumor induction of the testes by endocrine disrupting action (mechanism via dopaminergic activity) was suggested (EFSA (2017)).

7	Reproductive toxicity	Category 2	Warning	H361	P308+P313 P201 P202 P280 P405 P501	[Rationale for the Classification] Based on (1), no effects on fertility were observed. However, based on (2) and (3), decreased litter size and increased mortality of embryos and fetuses were reported only at doses where maternal toxicity was observed, therefore, it was classified in Category 2. [Evidence Data] (1) In 2 two-generation reproduction toxicity studies dosed by feeding with rats, no effects on fertility were observed (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2015)). (2) In a developmental toxicity study with female rats dosed by gavage on gestational Days 6-15, reduced body weight gain (gestational Day 17) and decreased food consumption were noted in maternal animals, and decreased litter size, lower body weight and delayed ossification were observed in fetuses (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2015)). (3) In a developmental toxicity study with female rabbits dosed by gavage on gestational Days 6-18, decreased food consumption and decreased feces in maternal animals, and increased mortality in embryos and fetuses were observed (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2015)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
8	Specific target organ toxicity - Single exposure	Category 1 (blood system, respiratory organs), Category 2 (central nervous system)	Danger Warning	H370 H371	P308+P311 P260 P264 P270 P321 P405 P501	[Rationale for the Classification] There were no reports of single exposure to this substance in humans. As for experimental animals, based on (1), an effect on the blood system at a dose equivalent to Category 1 and effects on the central nervous system at a dose equivalent to Category 2 were observed, and based on (2), effects on the respiratory organs at a dose equivalent to Category 1 were noted. Therefore, it was classified in Category 1 (blood system, respiratory organs), Category 2 (central nervous system). [Evidence Data] (1) In a single dose oral toxicity test with dogs, reduced activity, vomiting, a very small increase in blood methemoglobin levels, etc. at or above 125 mg/kg (equivalent to Category 1), unsteady hind gait, trembling, etc. at 625 mg/kg (equivalent to Category 2) were observed, but no dead animals were found (JMPR (2005), Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2015)). (2) In a 4-hour single inhalation exposure test with rats, nose bleeding and so on (male), abnormal respiratory sound (female) and hypothermia and decreased respirations (both sexes) were observed by exposure to the aerosol of this substance at or above 0.905 mg/L (equivalent to Category 1), and dead animals were found at or above 1.68 mg/L (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2015), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2014)). [Reference Data, etc.] (3) In a single oral dose test in rats, clinical signs such as sedation, ptosis and ataxia were observed from the minimum dose of 4,350 mg/kg (exceeding the range of Category 2), but the effects at lower doses than that were unknown (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2015), A pesticide abstract and evaluation report (Food and Agricultural Materials Inspection Center, 2014)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
9	Specific target organ toxicity - Repeated exposure	Category 2 (blood system, thyroid)	Warning	H373	P260 P314 P501	[Rationale for the Classification] Based on (1) and (2), in an oral administration to experimental animals, effects on the blood system and thyroid were observed within the range of Category 2, therefore, it was classified in Category 2 (blood system, thyroid). [Evidence Data] (1) As a result of a 90-day test by dosing by feeding to rats at doses of 120-3,000 ppm, decreased erythrocyte counts and increased methemoglobin levels were observed at or above 600 ppm (male: 47 mg/kg/day, female: 54 mg/kg/day, equivalent to Category 2) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2015), EFSA (2017), JMPR (2000)). (2) As a result of a 1-year dog study dosed by feeding at 5-500 mg/kg/day, effects on the thyroid (increased organ weight, morphologically hyperfunctional images) were observed at or above 50 mg/kg/day (range of Category 2), and erythrocyte counts, hemoglobin levels and hematocrit were decreased at or above 350 mg/kg/day (exceeding the range of Category 2) (Risk Assessment Report (Pesticides) (Food Safety Commission of Japan, 2015), EFSA (2017), EPA Pesticide (1994)).
