1 | Acute toxicity (Dermal) | * |
- |
- | - |
[Rationale for the Classification] Based on (1), it was classified as "Not classified." [Evidence Data] (1) LD50 for rabbits: > 2,000 mg/kg (REACH registration dossier (Access on September 2019)) |
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) | Category 4 |
Warning |
H332 |
P304+P340
P261 P271 P312 |
[Rationale for the Classification] Based on (1), it was classified in Category 4. The category was changed from the previous classification by using new information source. [Evidence Data] (1) LC50 (aerosol, 4 hours) for rats: 2 mg/L (REACH registration dossier (Access on September 2019)) |
2 | Skin corrosion/irritation | * |
- |
- | - |
[Rationale for the Classification] Based on (1), it was classified as "Not classified." [Evidence Data] (1) In a skin irritation test with rabbits conducted according to OECD TG 404, no skin reaction was observed and the mean scores at 24/48/72 hours were all 0 (REACH registration dossier (Access on September 2019)). [Reference Data, etc.] (2) In an in vitro skin corrosion test using human skin model conducted according to OECD TG 431, the tissue viability after 3-minute and 60-minute exposure was 41% and 0%, respectively, and it was judged to be corrosive (REACH registration dossier (Access on September 2019)). |
3 | Serious eye damage/eye irritation | * |
- |
- | - |
[Rationale for the Classification] Based on (1), it was classified as "Not classified." The category was changed since new data were obtained. [Evidence Data] (1) In an eye irritation test with rabbits conducted according to OECD TG 405, irritation scores at 24/48/72 hours were all 0 (REACH registration dossier (Access on September 2019)). [Reference Data, etc.] (2) It was classified in "Eye Dam. 1 (H318)" in the EU-CLP classification (EU CLP classification (Access on September 2019)). |
4 | Respiratory sensitization | * |

[Rationale for the Classification] Classification not possible due to lack of data. |

P302+P352
P333+P313 P362+P364 P261 P272 P280 P321 P501 |
[Rationale for the Classification] Based on (1), it was classified in Category 1. The category was changed since new data were obtained. [Evidence Data] (1) Divalent tin compounds are reported to be positive in a human patch test (REACH registration dossier (Access on September 2019)). [Reference Data, etc.] (2) This substance was predicted to not be sensitising to guinea pigs by QSAR (REACH registration dossier (Access on September 2019)). |
5 | Germ cell mutagenicity | * |
- |
- | - |
[Rationale for the Classification] Classification not possible due to lack of data. |
6 | Carcinogenicity | * |
- |
- | - |
[Rationale for the Classification] Classification not possible due to lack of data. [Reference Data, etc.] (1) 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 potential of inorganic tin compounds to cause reproductive and developmental toxicity. No adverse effects were found in rats when tin was given in the diet for three generations or when 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 | * |
- |
- | - |
[Rationale for the Classification] Classification not possible due to lack of data. It was impossible to confirm the description in ACGIH-TLV (2006) that inorganic tin compounds are irritating to the respiratory tract, which is evidence of respiratory tract irritation in the previous classification. Therefore, the classification result was changed. |
9 | Specific target organ toxicity - Repeated exposure | Category 1 (lung), Category 2 (liver, blood system) |
Danger Warning |
H372
H373 |
P260
P264 P270 P314 P501 |
[Rationale for the Classification] Based on (1) and (2), effects on human lungs may occur by inhalation exposure to metallic tin and inorganic tin compounds, and based on (3), effects on the liver and blood system were observed within the range of Category 2 by oral administration to rats, therefore, it was classified in Category 1 (lung), Category 2 (liver, blood system). [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 (TLV-TWA of 2 mg/m3 as inhalable particulate matter) for elemental tin, tin oxides and tin inorganic compounds (excluding tin hydride and indium tin oxide) in order to prevent stannosis (ACGIH (7th, 2019)). (3) In a 4-week feeding study with rats, decreased hemoglobin and hematocrit, bile duct hyperplasia and homogenous hepatocyte cytoplasm were observed at or above 86 mg/kg/day (converted guidance value: 27 mg/kg/day, within the range of Category 2) (ATSDR (2005), CICAD 65 (2005), EHC 15 (1980), de Groot et al. (1973)). |
