PHYSICAL HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification
1	Explosives	*	- -	-	-	There is a chemical group associated with explosive properties (nitro group) present in the molecule, and the calculated oxygen balance is -183, higher than the criteria: -200, but the classification is not possible due to no data.
2	Flammable gases	*	- -	-	-	Solid (GHS definition). It was classified as "Not classified (Not applicable)."
3	Aerosols	*	- -	-	-	Not aerosol products. It was classified as "Not classified (Not applicable)."
4	Oxidizing gases	*	- -	-	-	Solid (GHS definition). It was classified as "Not classified (Not applicable)."
5	Gases under pressure	*	- -	-	-	Solid (GHS definition). It was classified as "Not classified (Not applicable)."
6	Flammable liquids	*	- -	-	-	Solid (GHS definition). It was classified as "Not classified (Not applicable)."
7	Flammable solids	*	- -	-	-	No data available.
8	Self-reactive substances and mixtures	*	- -	-	-	There is a chemical group associated with explosive properties (nitro group) present in the molecule, but the classification is not possible due to no data.
9	Pyrophoric liquids	*	- -	-	-	Solid (GHS definition). It was classified as "Not classified (Not applicable)."
10	Pyrophoric solids	*	- -	-	-	No data available.
11	Self-heating substances and mixtures	*	- -	-	-	No data available.
12	Substances and mixtures which, in contact with water, emit flammable gases	*	- -	-	-	The chemical structure of the substance does not contain metals or metalloids (B, Si, P, Ge, As, Se, Sn, Sb, Te, Bi, Po, At). It was classified as "Not classified (Not applicable)."
13	Oxidizing liquids	*	- -	-	-	Solid (GHS definition). It was classified as "Not classified (Not applicable)."
14	Oxidizing solids	*	- -	-	-	The substance is an organic compound containing oxygen (but not fluorine or chlorine), which is chemically bonded to an element (N) other than carbon or hydrogen. However, the classification is not possible due to no data.
15	Organic peroxides	*	- -	-	-	Organic compounds containing no bivalent -O-O- structure in the molecule. It was classified as "Not classified (Not applicable)."
16	Corrosive to metals	*	- -	-	-	Classification is not possible because test methods applicable to solid substances are not available.
17	Desensitized explosives	*	- -	-	-	It was classified as "Not classified" because it is not desensitized by wetting, dilution, etc.

HEALTH HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification
1	Acute toxicity (Oral)	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
1	Acute toxicity (Dermal)	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
1	Acute toxicity (Inhalation: Gases)	*	- -	-	-	[Rationale for the Classification] Solid (GHS definition). It was classified as "Not classified (Not applicable)."
1	Acute toxicity (Inhalation: Vapours)	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
1	Acute toxicity (Inhalation: Dusts and mists)	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
2	Skin corrosion/irritation	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
3	Serious eye damage/eye irritation	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
4	Respiratory sensitization	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
4	Skin sensitization	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
5	Germ cell mutagenicity	*	- -	-	-	[Rationale for the Classification] There are no in vivo data. Therefore, classification was not possible due to lack of data. [Evidence Data] (1) As for in vitro, there are reports that it was positive in bacterial reverse mutation tests and a chromosomal aberration test (IARC 27 (1982), NTP DB (Access on October 2019)).
6	Carcinogenicity	Category 2	Warning	H351	P308+P313 P201 P202 P280 P405 P501	[Rationale for the Classification] Based on classification results by other organizations of (1), it was classified in Category 2 in accordance with the GHS Classification Guidance for the Japanese Government. [Evidence Data] (1) As for classification results by domestic and international organizations, it was classified in Group 2B by IARC (IARC Sup.7 (1987)), and Group 2B by the Japan Society For Occupational Health (JSOH) (Recommendation of Occupational Exposure Limits, 1991).
7	Reproductive toxicity	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
8	Specific target organ toxicity - Single exposure	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
9	Specific target organ toxicity - Repeated exposure	Category 2 (stomach)	Warning	H373	P260 P314 P501	[Rationale for the Classification] Based on (1), it was classified in Category 2 (stomach). Besides, though gastric lesions may be local effects due to irritation, the stomach was adopted as the target organ since no information on the irritancy of this substance was available. [Evidence Data] (1) In a 78-week carcinogenicity test with rats dosed by feeding at 0.06 and 0.12% (30 and 60 mg/kg/day, within the range of Category 2), nonneoplastic stomach lesions (basal cell hyperplasia, hyperkeratosis, acanthosis) were observed (NTP TR29 (1978)). [Reference Data, etc.] (2) In a 6-week test with rats dosed by feeding at 0.05-5.0%, reductions in weight gain (14% for male, 3% for female) were observed at or above 0.15% (converted guidance value: 35 mg/kg/day, within the range of Category 2) (IARC 27 (1982)).
10	Aspiration hazard	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.

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.
