Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification	Classification year (FY)	GHS Classification Guidance for the Japanese Government
1	Acute toxicity (Oral)	Category 4	Warning	H302	P301+P312 P264 P270 P330 P501	Two LD50 values for rats of 4,940 mg/kg bw (ECETOC JACC 20 (1992)), 1,400 mg/kg (HPVIS (2009)) were obtained, one corresponds to "Not classified" (corresponding to Category 5 in UN GHS classification), and the other corresponds to Category 4. Therefore, from a safety point of view, the category with higher hazard was adopted, and it was classified in Category 4.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）

1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Liquid (GHS definition)	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	Data are lacking. Besides, it is described that no deaths or symptoms were observed as a result of 8-hour exposure to the saturated vapour of this substance in rats (BUA 172 (1995)).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
2	Skin corrosion/irritation	Category 1	Danger	H314	P301+P330+P331 P303+P361+P353 P305+P351+P338 P304+P340 P260 P264 P280 P310 P321 P363 P405 P501	It was classified in Category 1 because it was corrosive in a skin irritation test in which 0.5 mL of this substance was applied to rabbits for 1-8 hours (USEPA/HPV (2001)), it was highly irritating and the primary dermal irritation index (PDII) was 6.2 in another test by a 24-hour occlusive application of 0.5 mL of undiluted this substance to rabbits (HPVIS (2009)). Besides, in tests with rabbits other than the above tests, it is also reported that PDII was 0, and it was not irritating after a 24-hour occlusive application of 0.5 mL, and PDII was 4.85, it was irritating but not corrosive after a 48-hour occlusive application (HPVIS (2009)).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
3	Serious eye damage/eye irritation	Category 1	Danger	H318	P305+P351+P338 P280 P310	It was classified in Category 1 because it was judged as corrosive in an eye irritation test in which 100 microL of this substance was applied to rabbits (USEPA/HPV (2001)), all the total mean scores (equivalent to AOI) were 98 or above (110 being the most severe) at 1, 2, 3, and 7 days after the application, and it was judged as corrosive in another eye irritation test with six rabbits (Federal Register) (HPVIS (2009)).

4	Respiratory sensitization	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
4	Skin sensitization	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
5	Germ cell mutagenicity	Classification not possible	- -	-	-	The classification is not possible due to no in vivo test data. Besides, as for in vitro tests, there are reports on a negative result in an Ames test (ECETOC JACC 20 (1992)) and a negative result in a mouse lymphoma test (HPVIS (2009)).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
6	Carcinogenicity	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
7	Reproductive toxicity	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	In an acute toxicity test in which 500-3,000 mg/kg was orally administered to rats (LD50: 1,400 mg/kg), depression and deaths were observed in all dose groups, but a necropsy revealed no gross alterations related to exposure (HPVIS (2009)). And in an acute toxicity test in which 500 or 5,000 mg/kg was orally administered to rats (10 animals/group), all animals died after administration of 5,000 mg/kg, there were no deaths after administration of 500 mg/kg, and general signs in survivors (500 mg/kg dose group) were limited to nasal discharge and diarrhea (HPVIS (2009)). Despite the above reports, the details of effects at doses within the guidance value range are unknown, therefore it was classified as "Classification not possible" due to lack of data.

11	Hazardous to the aquatic environment Short term (Acute)	Category 3	- -	H402	P273 P501	It was classified in Category 3 from 48-hour EC50 = 15 mg/L for crustacea (Daphnia magna) (Results of Aquatic Toxicity Tests of Chemicals conducted by Ministry of the Environment in Japan (Ministry of the Environment, 2009)).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
11	Hazardous to the aquatic environment Long term (Chronic)	Category 3	- -	H412	P273 P501	If chronic toxicity data are used, then it is classified as "Not classified" from 72-hour NOEC = 9.3 mg/L for algae (Pseudokirchneriella subcapitata) (Results of Aquatic Toxicity Tests of Chemicals conducted by Ministry of the Environment in Japan (Ministry of the Environment, 2009)) although it is not rapidly degradable (not readily degradable, a degradation rate by BOD: 0-17% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1985)). If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, then it is classified in Category 3 due to being not rapidly degradable (not readily degradable, a degradation rate by BOD: 0-17% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1985)), and 48-hour EC50 = 15 mg/L for crustacea (Daphnia magna) (Results of Aquatic Toxicity Tests of Chemicals conducted by Ministry of the Environment in Japan (Ministry of the Environment, 2009)). By drawing a comparison between the above results, it was classified in Category 3.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
