This database has information about all approved hazardous substances. Use this database to find out the hazardous classifications and controls of the substance. You can search this database by substance name or approval number. If an approval number doesn't produce a result, it may mean that the substance's approval is covered by a group standard. Copy and paste the link below into your browser to find out more about group standards. https://www.epa.govt.nz/industry-areas/hazardous-substances/group-standards/ This database has been updated to incorporate Aotearoa New Zealand's adoption of the GHS system of hazard classification. The controls for substances have been updated and many substances have had a change of approval status as well. The change in approval status to move many substances into Group Standards means there are fewer substances available in this search (around 9,000 individual approvals have been reduced to around 3,000). If you can no longer find the substance you require, you can view the Hazardous substance approval page which contains a full overview of the changes we have made (copy and paste the link below into your browser). https://www.epa.govt.nz/industry-areas/hazardous-substances/rules-for-hazardous-substances/approvals/ The controls for a small number of substances are still being reviewed, so have not been added to the database. The current controls for these substances are contained in the substance's decision document in the HSNO Application Register database.
