About the New Zealand Inventory of Chemicals (NZIoC)

The NZIoC is a database of all the hazardous chemical components of products approved under group standards. (Non-hazardous chemicals are not required to be listed.)

Many group standards require the hazardous components of products covered under these approvals to be listed on the NZIoC.

If you have a new product, you can check the list to see if you comply with the group standard condition. 

You can download a spreadsheet of the full NZIoC listings here:

What does '​​​inventory status' mean?

Chemicals listed on the NZIoC have been given an inventory 'status'. There are three options:

A. Where a substance has an individual HSNO approval. The HSNO approval code will be displayed.

B. The substance is present in New Zealand in its own right but does not have an individual approval. These substances can be used as single component products under an appropriate group standard approval. For example, CAS 100085-40-3.

C. The substance can only be used as a component in a product assigned to a group standard approval. It cannot be used as a product in its own right. For example, CAS 1000-90-4.

For A and B: The chemical can be used as a single chemical or as a component in a product included under a group standard approval.

For C: The chemical can only be used as a component in a product included under a group standard. Import and manufacture of the pure chemical may require an application for individual approval.

 Why are some non-hazardous chemicals on the NZIoC?​

When the NZIoC was created, ERMA did not have hazard data on many chemicals so did not know if they were hazardous or non-hazardous. The decision was made to list all chemicals at that time. However, it is not mandatory to list non-hazardous chemicals.
