I noticed an interesting article at
about the challenge of GHS:
What does GHS stand for?
Chemwatch have undertaken a systematic comparison of GHS classification published by official sources in:
New Zealand (CCID)
A total of 12,452 Substances were reviewed.
Interestingly there was very little overlap between Substances reviewed by any two Jurisdictions - Korea and New Zealand reviewed 1494 Substances in common.
However, where Substances in common where assigned GHS Classifications, fewer than 8% were in agreement - New Zealand and the European Union agreed on only 75 Substances of 939 Substances.
< 8% Harmonisation between any 2 Jurisdictions
< 0.6% Harmonisation between any 3 Jurisdictions
I'm not quite sure of what to make of this data. I wonder if anyone on the list has done international comparisons that include the US?
