2	Skin corrosion/irritation	Classification not possible	- -	-	-	Classification not possible due to lack of data. Besides, it is reported in CICAD 27 (2000) that in an irritation test in which the polymer of this substance was applied to rabbits for 24 hours, slight erythema was observed but disappeared within seven days. And this substance is classified in "Xi; R36/38" in EU DSD classification and "Skin Irrit. 2 H315" in EU CLP classification.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	[Rationale for the Classification] Classification is not possible due to lack of data. Although there is information of (2)-(4), it was not used for the classification because it is information on isomer mixtures. Besides, an isomer mixture of this substance was classified in Category 2B in serious eye damage/eye irritation (please refer to CAS: 26447-40-5), and 4,4'-isomer was classified in Category 2B (please refer to CAS: 101-68-8). [Reference Data, etc.] (1) It was classified in Eye Irrit. 2 in EU CLP. (2) Methylenediphenyl isocyanate (MDI) is known as an eye irritant (SIAR (2003), CICAD (2000)). (3) It is reported that in an eye irritation test with rabbits (OECD TG405, GLP-compliant, n = 3), after application of an undiluted isomer mixture containing this substance (2,2'-MDI: 0.64%, 2,4'-MDI: 53.60%, 4,4'-MDI: 45.72%), scores for corneal opacity, iris, conjunctival redness, and chemosis were 0 after 72 hours, and eye irritation was not seen (REACH registration dossier (Accessed Dec. 2018)). (4) It is reported that in an eye irritation test with rabbit (n = 6), after application of an undiluted this substance (MDI isomer mixture, purity 92-95%), macroscopic observation showed no immediate change in the cornea, moderate conjunctivitis was found after 24 hours, and four out of six animals recovered within seven days while conjunctivitis persisted in the other two (REACH registration dossier (Accessed Dec. 2018)). (5) As for methylenediphenyl isocyanate including 4,4'-isomer, skin disorders, anterior eye disorders, or respiratory tract disorders were designated as occupational diseases based on Appended Table 1-2, (iv) 1 of the Ordinance for Enforcement of the Labor Standards Act.

4	Respiratory sensitization	Category 1	Danger	H334	P304+P340 P342+P311 P261 P284 P501	In CICAD 27 (2000), many cases show the effects of this substance on respiratory organs in humans. Furthermore, it is classified in "R42/43" in EU DSD classification and "Resp. Sens. 1 H334" in EU CLP classification. Based on the above information, it was classified in Category 1.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
4	Skin sensitization	Category 1	Warning	H317	P302+P352 P333+P313 P362+P364 P261 P272 P280 P321 P501	It is reported that it was sensitizing in a mouse ear-swelling test (CICAD 27 (2000)). Furthermore, in CICAD 27 (2000), many cases are showing that this substance was a skin sensitizer in humans. Moreover, this substance is classified in "R43" in EU DSD classification and "Skin Sens. 1 H317" in EU CLP classification. Based on the above information, it was classified in Category 1.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
5	Germ cell mutagenicity	Classification not possible	- -	-	-	Classification not possible due to lack of data. As for in vivo, it was negative in a test in which DNA adduct formation in rat liver was investigated (CICAD 27 (2000)). As for in vitro, it was negative in a bacterial reverse mutation test (CICAD 27 (2000)).	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
6	Carcinogenicity	Classification not possible	- -	-	-	Because the mixture of the monomer and polymer of this substance is classified in Group 3 in CICAD (2000), it was classified as "Classification not possible." Besides, it is classified in 3 by the EU.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
7	Reproductive toxicity	Classification not possible	- -	-	-	Classification not possible due to lack of data. Besides, no developmental toxicity was observed in a developmental toxicity test with rats in the inhalation route (CICAD 27 (2000)). No report on fertility was obtained.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	Classification is not possible due to lack of data because there are no reports on the effects of repeated exposure to this substance in either humans or experimental animals. Besides, as for 4,4'-diphenylmethane diisocyanate, the isomer of this substance, it is reported that after 1-year inhalation exposure to aerosol, rats showed histopathological findings in the lung (focal alveolar and bronchioalveolar hyperplasia, interstitial fibrosis, an accumulation of particle-laden and pigmented macrophages) at the concentration (converted guidance value: 0.00046 mg/L) corresponding to Category 1 (CICAD 27 (2000)).
