HEALTH HAZARDS

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	There are reports on LD50 values for rats of 1,389 mg/kg (EPA Pesticide (1993)) and > 2,000 mg/kg (JECDB (Access on October 2013)) (OECD TG 401). Because there are the same numbers for both Category 4 and "Not classified," it was classified in Category 4 according to the GHS classification guidance for the Japanese government.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Solid (GHS definition)	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Inhalation: Vapours)	Not classified (Not applicable)	- -	-	-	Solid (GHS definition)	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
2	Skin corrosion/irritation	Classification not possible	- -	-	-	Classification not possible due to lack of data. Besides, this substance is classified in "Xi; R36/38" in EU DSD classification and "Skin Irrit. 2 H315" in EU CLP classification.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	Classification not possible due to lack of data. Besides, this substance is classified in "Xi; R36/38" in EU DSD classification and "Eye Irrit. 2 H319" in EU CLP classification.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
4	Respiratory sensitization	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
4	Skin sensitization	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
5	Germ cell mutagenicity	Classification not possible	- -	-	-	It was classified as "Classification not possible" because it was not possible to classify a substance as "Not classified" according to the revised GHS classification guidance for the Japanese government. There is the knowledge that it was negative in an in vivo micronucleus test with the stomach, duodenum, and colon (J. Appl. Toxicol. 8, 179-183, 1988), and a category of iron salts was assessed in SIDS, and the category was evaluated to be not mutagenic in vivo. As for in vitro, it was negative in a bacterial reverse mutation test and positive in a chromosomal aberration test with cultured mammalian cells (JECDB (Access on October 2013)).	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
6	Carcinogenicity	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
7	Reproductive toxicity	Classification not possible	- -	-	-	Classification not possible due to lack of data. Besides, in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test (OECD TG422) with rats in the oral route (gavage), no fertility effects were observed at the dose (1,000 mg/kg/day) where effects were seen in parent animals. And no effects were found in offspring (JECDB (Access on October 2013)). However, because it is a screening test, and there are no sufficient reports on developmental toxicity, it was classified as "Classification not possible."	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	Classification not possible due to lack of data. Besides, it is reported that after gavage administration to rats, a decrease in locomotor activity, salivation, and a transient decrease in body weights were observed at 2,000 mg/kg, the maximum guidance value, but no other toxic signs were found (JECDB (Access on October 2013)). However, there are no reports on the other routes.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	This substance was recognized as GRAS (Generally Recognized As Safe) substance as food additives by the U.S. FDA (EPA Pesticide (1993)). Furthermore, in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test with rats by gavage administration, increased extramedullary hematopoiesis in the spleen (only in males) was observed at the dose (163 mg/kg/day (converted guidance value)) above the guidance value range for Category 2 (JECDB (Access on Sep. 2013)). From the above, it corresponds to "Not classified" in the oral route. However, because of no toxicity information on the other routes, the classification is not possible due to lack of data.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
10	Aspiration hazard	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))

ENVIRONMENTAL HAZARDS

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
11	Hazardous to the aquatic environment Short term (Acute)	Category 3	- -	H402	P273 P501	From 48-hour EC50 = 91 mg/L for crustacea (Daphnia magna) (SIDS, 2008), it was classified in Category 3.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
11	Hazardous to the aquatic environment Long term (Chronic)	Not classified	- -	-	-	If chronic toxicity data are used, then it is classified as "Not classified" due to no appropriate data obtained on rapid degradability, and 21-day NOEC = 10 mg/L for crustacea (Daphnia magna) (SIDS, 2008). If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, then it is classified as "Not classified" due to 96-hour LC50 > 67 mg/L for fish (Oryzias latipes) (SIDS, 2008) although appropriate data on rapid degradability were not obtained. From the above results, it was classified as "Not classified."	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
12	Hazardous to the ozone layer	Classification not possible	- -	-	-	This substance is not listed in the Annexes to the Montreal Protocol.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
