1	Acute toxicity (Oral)	Category 2	Danger	H300	P301+P310 P264 P270 P321 P330 P405 P501	The higher toxic value (LD50=9.16mg/kg) was adopted among rat LD50=13mg/kg and 9.16mg/kg (HSDB (2003)), and it was classified as category 2.	FY2006	GHS Classification Manual （10 Feb, 2006）
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	No data available	FY2006	GHS Classification Manual （10 Feb, 2006）

2	Skin corrosion/irritation	Classification not possible	- -	-	-	Original literature is unknown although there is description which suggests the irritation on the human skin (SITTIG (4th, 2002), HSFS (2002)). On the other hand, negative skin irritation is indicated with rat in dose finding study (HSDB (2003)). But data is insufficient for carrying out a GHS classification, and it could not be classified.	FY2006	GHS Classification Manual （10 Feb, 2006）
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	Although there is the description which suggests the irritative against the human eyes (HSFS (2002)), the original literature is unknown. On the other hand, although the negative eye irritation is indicated to rabit eyes with dose finding study (HSDB (2003)), data is insufficient for carrying out GHS classification, Therefore, it cannot be classified.	FY2006	GHS Classification Manual （10 Feb, 2006）
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available	FY2006	GHS Classification Manual （10 Feb, 2006）

Therefore, it cannot be classified.	FY2006	GHS Classification Manual （10 Feb, 2006）
7	Reproductive toxicity	Classification not possible	- -	-	-	Classification not possible due to lack of data	FY2006	GHS Classification Manual （10 Feb, 2006）
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	Although there is a report that "it causes pulmonary edema, and can cause irritation to nose and throat," there are no data supporting this report. Therefore, the substance cannot be classified due to insufficient data.	FY2006	GHS Classification Manual （10 Feb, 2006）
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	Although there is description of "a disorder being done to a nervous systems by a repeated doses" (SITTIG (2002), HSFS (2002)) and "marrow may be affected and anemia may be occured" (HSFS (2002)), to humans, there is no data which endorses these description, and it cannot be classified due to insufficient data.

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	It was classified in Category 3 from 48-hour EC50 (immobile) = 12 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, 2018)).	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
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" due to being not rapidly degradable (not readily degradable, an average degradation rate by BOD: 0% (J-CHECK, 1987)), and 72-hour NOEC (growth rate) = 2.8 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, 2018)). 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, an average degradation rate by BOD: 0% (J-CHECK, 1987)), and 48-hour EC50 (immobile) = 12 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, 2018)). From the above results, it was classified in Category 3.	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
12	Hazardous to the ozone layer	Classification not possible	- -	-	-	No data available.	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))

NOTE:

GHS Classification Result by the Japanese Government is intended to provide a reference for preparing a GHS label or SDS for users. To include the same classification result in a label or SDS for Japan is NOT mandatory.
Users can cite or copy this classification result when preparing a GHS label or SDS. Please be aware, however, that the responsibility for a label or SDS prepared by citing or copying this classification result lies with users.
This GHS classification was conducted based on the information sources and the guidance for classification and judgement which are described in the GHS Classification Guidance for the Japanese Government etc. Using other literature, test results etc. as evidence and including different content from this classification result in a label or SDS are allowed.
Hazard statement and precautionary statement will show by hovering the mouse cursor over a code in the column of "Hazard statement" and "Precautionary statement," respectively. In the excel file, both the codes and statements are provided.
A blank or "-" in the column of "Classification" denotes that a classification for the hazard class was not conducted in the year.
An asterisk “*” in the column of “Classification” denotes that “Not classified (or No applicable)” and/or “Classification not possible” is applicable. Details are described in the column of “Rationale for the classification”. If no English translation is available for “Rationale for the classification,” please refer to the Japanese version of the results.
