PHYSICAL HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification
1	Explosives	*	- -	-	-	It contains no chemical groups associated with explosive properties. It was classified as "Not classified (Not applicable)."
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	*	- -	-	-	There is information that it is combustible (ICSC (2004)), but the classification is not possible due to no data.
8	Self-reactive substances and mixtures	*	- -	-	-	It contains no chemical groups associated with explosive or self-reactive properties. It was classified as "Not classified (Not applicable)."
9	Pyrophoric liquids	*	- -	-	-	Solid (GHS definition). It was classified as "Not classified (Not applicable)."
10	Pyrophoric solids	*	- -	-	-	It was classified as "Not classified" because it is estimated that it does not ignite at normal temperatures from information: autoignition temperatures of 630 deg C (cloud), 430 deg C (layer) (HSDB (Access on August 2019)).
11	Self-heating substances and mixtures	*	- -	-	-	No data available.
12	Substances and mixtures which, in contact with water, emit flammable gases	*	- -	-	-	It is one of metalloids, but it is estimated to be stable in water from information that it is insoluble in water (ICSC (2004)). Therefore, it was classified as "Not classified."
13	Oxidizing liquids	*	- -	-	-	Solid (GHS definition). It was classified as "Not classified (Not applicable)."
14	Oxidizing solids	*	- -	-	-	Inorganic substances containing no oxygen or halogen atoms. It was classified as "Not classified (Not applicable)."
15	Organic peroxides	*	- -	-	-	It is not an organic compound. 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	*	- -	-	-	There are no chemical groups associated with explosive properties present in the molecule. It was classified as "Not classified."

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] Based on (1) and (2), it was classified as "Not classified." [Evidence Data] (1) No clear irritant reactions were seen when 73 nickel-sensitive patients were patch-tested with this substance (metallic tin) or when other subjects were patch-tested with this substance or 1% tin (II) chloride in petrolatum (CICAD 65 (2005)). (2) Tin metal is not a skin irritant (CICAD 65 (2005)).
3	Serious eye damage/eye irritation	Category 2	Warning	H319	P305+P351+P338 P337+P313 P264 P280	[Rationale for the Classification] Based on (1), it was classified in Category 2. Besides, the category was changed because data was newly obtained. [Evidence Data] (1) The dust of this substance is irritating to the eyes and airways (HSDB (Access on July 2019)).
4	Respiratory sensitization	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
4	Skin sensitization	*	- -	-	-	[Rationale for the Classification] Although there are data of (1) and (2), there are not enough data for classification. Therefore, it was classified as "Classification not possible." [Reference Data, etc.] (1) Patch tests with metallic tin in 73 nickel-sensitive patients revealed six positive allergic skin reactions (as well as four doubtful reactions) (CICAD 65 (2008), DFGOT vol.14 (2000)). (2) One out of 50 craftsmen in the ceramics industry had a positive reaction when patch-tested with 2.5% metallic tin dispersed in petrolatum (CICAD 65 (2008)).
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 all negative reports in a bacterial reverse mutation test, a chromosome aberration test and a gene mutation test with cultured mammalian cells (REACH registration dossier (Access on September 2019)).
6	Carcinogenicity	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data. [Reference Data, etc.] Limited in nature but available experimental animal studies with tin compounds have not shown tin metal, tin (II) chloride or a small number of other tin compounds to be carcinogenic (CICAD 65 (2005)).
7	Reproductive toxicity	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data. [Reference Data, etc.] (1) Only limited data were identified on the reproductive and developmental toxicity of inorganic tin compounds. No adverse effects were found in rats when tin was given in the diet for three generations or when some tin compounds were given in the diet throughout pregnancy. Similarly, repeated gavage treatment of pregnant rats, mice, and hamsters with tin (II) chloride was without adverse effect on the fetuses (CICAD 65 (2005)).
8	Specific target organ toxicity - Single exposure	Category 3 (Respiratory tract irritation)	Warning	H335	P304+P340 P403+P233 P261 P271 P312 P405 P501	[Rationale for the Classification] Based on (1), it was classified in Category 3 (respiratory tract irritation). The classification result was changed from the previous classification. [Evidence Data] (1) The dust of this substance is irritating to the eyes and airways (HSDB (Access on July 2019)).
9	Specific target organ toxicity - Repeated exposure	Category 1 (lung)	Danger	H372	P260 P264 P270 P314 P501	[Rationale for the Classification] Based on (1) and (2), since effects on human lungs are considered to be from inhalation exposure to metal tin and inorganic tin compounds, it was classified in Category 1 (lung). [Evidence Data] (1) Inhalation exposure to the dust and fume of tin (oxide) is recognized to result in stannosis (mild pneumoconiosis) (ACGIH (7th, 2019)). (2) The ACGIH recommends Threshold Limit Values in the workplace (a TLV-TWA of 2 mg/m3 as inhalable particulate matter) for elemental tin, tin oxides and tin inorganic compounds (except tin hydride and indium tin oxide) in order to prevent stannosis (ACGIH (7th, 2019)).
10	Aspiration hazard	*	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.
