2	Skin corrosion/irritation	Category 2	Warning	H315	P302+P352 P332+P313 P362+P364 P264 P280 P321	There are reports that in a skin irritation test with rats, necrosis and erythema of the epidermis were observed within 12-24 hours after application, but the necrotic epidermis peeled from the dermis, and the epidermis regenerated. The erythema resolved 72 hours after application (EHC 116 (1990), SIDS (2010)). In addition, there is a report that as a result of the application of the undiluted liquid of this substance to 5 volunteers, redness, itching, hair follicle inflammation, and mild edema occurred (SIDS (2010)). Based on the above result, it was classified in Category 2.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
3	Serious eye damage/eye irritation	Category 2A	Warning	H319	P305+P351+P338 P337+P313 P264 P280	Because there are descriptions that this substance is severely irritating to rabbits' eyes (DFGOT vol. 1 (1991)) and that "it is seriously irritating to the eyes" for human health effects (HSDB (Access on July 2014)), it was classified in Category 2A.	FY2014	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.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
5	Germ cell mutagenicity	Classification not possible	- -	-	-	As for in vivo, it was negative in a micronucleus test with bone marrow cells of mice (SIDS (2010)), as for in vitro, it was negative and positive in bacterial reverse mutation tests and negative in a mammalian cell chromosome aberration test (SIDS (2010), ATSDR (2005)). Therefore, it was classified as "Classification not possible."	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
6	Carcinogenicity	Classification not possible	- -	-	-	It is classified as A4 in ACGIH (7th, 2001) as an organic tin compound. Therefore, it was classified as "Classification not possible."	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
7	Reproductive toxicity	Category 1B	Danger	H360	P308+P313 P201 P202 P280 P405 P501	It was reported that in a two-generation reproduction toxicity test with rats by the oral route (feeding), reproductive effects (decreases in litter size, live birth index, pup body weight and pup body weight gain) were observed at a dose (10 mg/kg/day) where maternal toxicity (decreased body weight gain) appeared, and even at a dose (0.4 mg/kg/day) where maternal toxicity did not appear, effects on pups' genetic organs (decreases in weight of the testis and epididymis, decreases in spermatid and sperm counts, increased AGD (anogenital distance) in female pups) were observed (SIDS (2010)). There is a report that in a teratogenicity test with rats by the oral route (gavage), embryo loss, decreased fetal body weight gain, and teratogenicity (mainly cleft palate) were observed at a dose (25 mg/kg/day) where maternal toxicity (decreased body weight gain) appeared (SIDS (2010)). Although it was impossible to classify because of no data in the previous classification, the new information available for classification having been obtained. Therefore, it was classified in Category 1B.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
8	Specific target organ toxicity - Single exposure	Category 1 (central nervous system, liver), Category 3 (respiratory tract irritation)	Danger Warning	H370 H335	P308+P311 P260 P264 P270 P321 P405 P501 P304+P340 P403+P233 P261 P271 P312	There are no hazard findings on single exposures in humans. In experimental animals, there are reports of slight irritation in the nose and inflammatory changes in the respiratory tract by inhalation exposure to rats (SIDS (2010)), and reports of damage to the common ductus hepaticus and common bile duct, ulcerative inflammation of the bile duct, and necrosis of the bile duct at or above 29.6 mg/kg by oral dose to Syrian hamsters (ATSDR (2005), Takagi et al. (1992)). Necrotic pneumonia, gastrointestinal tract bleeding or hyperemia were observed in dead animals from an oral dose of 45-250 mg/kg to rats (SIDS (2010)). A significant increase in the enzyme (ornithine carbamyl transferase in the blood) which is the index for hepatotoxicity was shown at 58 mg/kg by oral dose to mice (ATSDR (2005)). In other, hunched back and piloerection were observed at 187.5 mg/kg after oral dose to mice, and sluggishness, piloerection, hunched back and closeness were observed at 375-2,000 mg/kg (SIDS (2010)). In addition, there is a description that "tributyltin compounds could possibly damage the central nervous system." (DFGOT vol. 1 (1991)). The effects on the liver and the central nervous system in experimental animals were observed within the guidance value range for Category 1. In the previous classification, there is a description of "a steatosis of the liver cells, traces of lipids in the renal tubule cells, hemorrhages in the digestive tract and kidneys" (EHC 116 (1990)), and it was classified in Category 2 (liver, kidney). However, EHC rejected these findings (based on 500 mg/kg oral dose to mice) because no right conclusion can be drawn due to no clear evidence concerning steatosis of the liver and kidney. Therefore, this finding was not adopted. Moreover, because there are no findings of effects on the kidney, the kidney was not adopted as a target organ. Besides, it is described that organic tin compounds may be irritating to the respiratory tract (ATSDR (2005), ACGIH (7th, 2001)). From the above, although there are no findings on humans, from the data in experimental animals, respiratory tract irritation was considered for this substance in addition to the effects on the central nervous system and liver. Therefore, it was classified in Category 1 (central nervous system, liver), Category 3 (respiratory tract irritation).

9	Specific target organ toxicity - Repeated exposure	Category 1 (immune system, respiratory organs, liver)	Danger	H372	P260 P264 P270 P314 P501	There are no hazard findings on repeated exposures in humans. In experimental animals, in a test in which rats were dosed by feeding for 14 days or 28 days, at doses (0.75-9.2 mg/kg/day (converted guidance value: 0.12-2.86 mg/kg/day)) within the range of Category 1, the effects on the immune system such as the effects on the thymus (reduction of thymus weight, reduction in thymus cell counts, lymphocytes depletion), decreased spleen weights, reddening in the mesenteric lymph nodes were observed, and an increase in relative liver weight was also observed (SIDS (2010), DFGOT vol. 1 (1991)). In addition, there is a report that in a test in which rats were exposed by inhalation of this substance (estimated as mist state) for 95 days, lung hyperemia, catarrhal bronchitis and fatty degeneration of the liver were observed at the concentration of 0.3 ppm (4 mg/m3: 0.004 mg/L/6 hours) (ATSDR (2005)). From the above, based on the findings on experimental animals, it was classified in Category 1 (immune system, respiratory organs, liver).
