ECHA Classification & Labelling Inventory Database

https://echa.europa.eu/information-on-chemicals/cl-inventory-database

This database contains classification and labelling information on notified and registered substances received from manufacturers and importers. It also includes the list of Harmonised Classifications.

Jeff Simpson: It is useful to see the variations in GHS Chemical Hazard Classifications on this database and compare them to the ECHA Registered Substances Database hazard classifications. Be aware that with this database you need to carefully consider the real data for the chemical mixture before you classify, as impurities affect how the companies classify their products.

New Zealand Chemical Classification and Information Database (CCID)

https://www.epa.govt.nz/database-search/

Note: These classifications are mandated by the NZ HSNO Regulations, BUT there are many not quite correct classifications, where the Common Law correct classification would override the not quite correct one. So be very careful with NZ classifications. And when you find a discrepancy, notify the NZ EPA.

Every year NZ reviews classifications on this database that have been advised to not be correct and updates them.

NOTE Differences in the Hazardous Substances Information System by Safe Work Australia
which has been updated with the classifications from the NICNAS (now AICIS) IMAP reviews. There are several classifications that are now different from the ECHA Hazardous Chemicals Classifications (e.g. Toluene), which may lead to problems with EU labelled products in Australia.

ALSO the previous cut-off concentrations are no longer listed (as they still are on the ECHA C&LID) which may cause an AU GHS classification even though not classified in the EU.
