6	Carcinogenicity	Category 1B	Danger	H350	P308+P313 P201 P202 P280 P405 P501	[Rationale for the Classification] Based on (1) and (2), clear evidence of carcinogenicity including malignant tumors was observed in two animal species, and based on (3), this substance is a target substance in the public announcement on guidelines in order to prevent the impairment of worker's health caused by the chemical substances decided by the Minister of Health, Labour and Welfare based on paragraph (3) of Article 28 of the Industrial Safety and Health Act, and emphasizing these, it was classified in Category 1B. Also, based on the new findings, the classification result was changed. [Evidence Data] (1) In a two-year carcinogenicity study with rats dosed by feeding, an increase in the incidence of kidney tumors (renal cell carcinoma, renal cell adenoma) was observed in males and females, and an increase in the incidence of adenoma of the preputial gland was observed in males (Results from Carcinogenicity Studies (Ministry of Health, Labour and Welfare, 2005), IARC 123 (2020)). (2) In a two-year carcinogenicity study with mice dosed by feeding, an increase in the incidence of liver tumors (hepatocellular adenoma, hepatocellular carcinoma, hepatoblastoma) and peritonea tumors (hemangiosarcoma) was observed in males and females (Results from Carcinogenicity Studies (Ministry of Health, Labour and Welfare, 2005), IARC 123 (2020)). (3) This substance is a target substance in the public announcement on guidelines in order to prevent the impairment of worker's health caused by the chemical substances decided by the Minister of Health, Labour and Welfare based on paragraph (3) of Article 28 of the Industrial Safety and Health Act (guidelines in order to prevent the impairment of worker's health, announcement No. 27 on February 7, 2020). (4) As for the carcinogenicity classification results by domestic and international assessment organizations, the IARC classified this substance in Group 2B (IARC 123 (2020)) and the Japan Society For Occupational Health (JSOH) classified it in Group 2B (Recommendation of Occupational Exposure Limits (2020): Classification in 2019).	FY2021	GHS Classification Guidance for the Japanese Government (FY2019 revised edition (Ver. 2.0))
7	Reproductive toxicity	Category 2	Warning	H361	P308+P313 P201 P202 P280 P405 P501	In a combined repeated dose toxicity study and reproductive/developmental toxicity screening study in rats (OECD TG 422, GLP), it is reported that no effects on mating fertility and estrous cycles were observed, but at 200 mg/kg, the dose at which toxicities (effects on the liver and kidney) manifest themselves in mother rats, two animals were stillborn and three female offspring rats died during the breast-feeding period, so the substance has effects on female reproduction and generation/development of the offspring (Ministry of Health, Labor and Welfare Report (Access on September 2008), SIDS (1996)). Therefore, it was classified as Category 2.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	Classification not possible due to lack of data	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
9	Specific target organ toxicity - Repeated exposure	Category 2 (liver, kidney)	Warning	H373	P260 P314 P501	It is written in the combination test of repeated dose toxicity study and reproduction screening study in rats (OECD TG 422, GLP) that effects on liver (hypertrophy of hepatocytes, and necrosis, etc.) and kidney (creatinine low level, necrosis of tubular epithelium, basophilic tubule change, etc.) were found, and target organs were considered to be liver and kidney (Ministry of Health, Labour and Welfare reports (Access on September 2008), SIDS (1996)). Since these effects were found within the scope of the guidance value of Category 2, it was classified into Category 2 (liver, kidney).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
10	Aspiration hazard	Classification not possible	- -	-	-	Classification not possible due to lack of data	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
