Additional information

According to the REACH Regulation (EC n. 1907/2006), Annex VII, Column 2, the study does not need to be conducted when the substance is highly flammable. Tetraphosphorus trisulphide is classified according to annex VI of the CLP regulation (EC n.1272/2008) as flammable solid (H228) and moreover it contains no oxygen or halogen atoms. No concern raises for oxidising potential of this substance.

Justification for classification or non-classification

The test substance is a flammable solid, it does not show oxidising properties based on its structural formula (it contains no oxygen or halogen atom) and no classification is required.
