Under GHS, what determines the classification of a chemical?

The classification of a chemical under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is primarily determined by the chemical's physical, health, and environmental hazards. This systematic approach takes into account a variety of factors including the inherent properties of the chemical, such as toxicity, flammability, and reactivity, as well as its potential impact on the environment.

This classification is essential for ensuring that appropriate safety measures are observed, and that information about the hazards is effectively communicated through labels and safety data sheets. It helps in the identification of risks associated with the chemical, ensuring proper handling and emergency response measures are in place. The other options, such as price, market availability, container size, and the manufacturer's name, do not pertain to the fundamental aspects that determine the safe handling and classification of chemicals according to international safety standards.
