GHS cut-off value or GHS concentration limit is the minimum concentration for a hazardous substance to trigger the classification of a mixture containing it. They are mainly expressed as % thresholds and are primarily used for mixture classification under GHS.
The table below is an example of cut-off value/concentration limit for hazard class skin corrosion/irritation. If a mixture contains a hazardous ingredient that has been classified as skin corrosive category 1, the mixture itself will also be classified as skin corrosive category 1 if the concentration of ingredient exceeds 5%.
In UN GHS, the cut-off value and concentration limit are equivalent and meant to be used interchangeably. It shall be noted that the EU CLP regulation has given different definitions to cut-off value and concentration limit. In addition to that, Europe has set specific concentration limits for specific substances.
There are some special considerations when using cut-off value and concentration limit to classify a mixture:
GHS has also set generic cut-off values for SDSs. An SDS should be prepared and provided for a substance or mixture meeting classification criteria or for a mixture containing a hazardous ingredient with a concentration exceeding the cut-off limits given in the table below.
