Definition: A harmonised classification is an EU-wide, legally binding classification of a substance listed in Table 3 of CLP Annex VI, which every supplier must apply.
Harmonised entries can include specific concentration limits, M-factors, ATEs and notes. Hazard classes not covered by the entry must still be self-classified by the supplier.
Annex VI is updated through Adaptations to Technical Progress (ATPs), each with a transition date. Using an outdated row is one of the most common SDS errors.
