ECHA CHEM
This is ECHA’s public chemicals database with information from all REACH registrations, Classification and Labelling Inventory and Regulatory lists and processes under REACH, CLP, DWD and POPs regulations.
This database contains classification and labelling information on substances received from manufacturers and importers. It also includes the list of Harmonised Classifications.

eChemPortal provides free public access to information on properties of chemicals by CAS No., Chemical Name; and by Physical Chemical Properties; Ecotoxicity; Environmental Fate and Behaviour; and Toxicity.
eChemPortal allows simultaneous searching of reports and datasets by chemical name and number, by chemical property, and by GHS classification.

New Zealand Chemical Classification and Information Database (CCID)
https://www.epa.govt.nz/database-search/
Note: These classifications were mandated by the NZ HSNO Regulations, BUT now most are no longer mandated with the GHS updated Regs. 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 Chemicals 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 which may cause an AU GHS classification even though not classified in the EU below the EU cut-offs.
