Chemical classification is used to regulate the supply and use of chemicals.
In some cases classification can act as the basis for requiring additional chemical controls, protective measures, or restrictions on sale or use. This is usually the case where the chemicals are particularly harmful, where they may have the chance of effecting a wide population or the environment because of the volumes involved, and where the chemicals are used in the workplace.
These additional controls or restrictions appear in other more specific pieces of law. The following is not a complete list of other laws which refer to classification to establish aspects of their scope, but gives an idea of how classification acts as the basis for much wider chemical regulation and why it is important to ensure it is accurate.
