| 9 | Pyrophoric liquids | Not applicable | - | - | - | - | Solid |
| 10 | Pyrophoric solids | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 11 | Self-heating substances and mixtures | Classification not possible | - | - | - | - | The test method applicable for substances becoming liquid or gas at 140degC of test temperature has not been established. |
| 12 | Substances and mixtures which, in contact with water, emit flammable gases | Not applicable | - | - | - | - | Metals or metalloids (B, Si, P, Ge, As, Se, Sn, Sb, Te, Bi, Po, At) are not included. |
| 13 | Oxidizing liquids | Not applicable | - | - | - | - | Solid |
| 14 | Oxidizing solids | Not applicable | - | - | - | - | Although it is an organic compound including oxygen, not fluorine and chlorine, this oxygen has not chemically bound to any elements other than carbon and hydrogen. |
| 15 | Organic peroxides | Not applicable | - | - | - | - | The organic compound not including peroxy group in molecule. |

| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 1 | Acute toxicity （Oral） | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 1 | Acute toxicity （Dermal） | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 1 | Acute toxicity （Inhalation: Gases） | Not applicable | - | - | - | - | Since it was a solid by the definition of GHS and inhalation in gas was not assumed, it was classified into "Not applicable". |
| 1 | Acute toxicity （Inhalation: Vapours） | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 1 | Acute toxicity （Inhalation: Dusts and mists） | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 2 | Skin corrosion/irritation | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 3 | Serious eye damage/eye irritation | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 4 | Respiratory sensitization | Classification not possible | - | - | - | - | Classification is not possible since there is no data. In addition, although there has been a description that "Isocyanate had a sensitization to human respiratory organs" (EHC 212 (1999)), the information on the substance itself could not be acquired. |
| 4 | Skin sensitization | Classification not possible | - | - | - | - | Since there is no data, classification is not possible. In addition, there is a description of "Sensitization:Sen" (ACGIH-TLV/BEI (2006)) with the generic descriptor of "Isocyanates." |
| 5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | Classification is not possible because there is no data. In addition, although there is a description that "the strong mutagenicity is observed." in the existing chemical substances mutagenicity inspection result in the labor security and hygiene law (CHRIP (Access on October 2008)), there is no data of in vivo examination. |
| 6 | Carcinogenicity | Classification not possible | - | - | - | - | Since no evaluation by major international evaluation agencies is made and there is no data, classification is not possible. |
| 7 | Reproductive toxicity | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 8 | Specific target organ toxicity - Single exposure | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 10 | Aspiration hazard | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 11 | Hazardous to the aquatic environment （Acute） | Classification not possible | - | - | - | - | No data available |
| 11 | Hazardous to the aquatic environment （Long-term） | Classification not possible | - | - | - | - | No data available |
