This is a brief overview of how to assign a product to a group standard. More in-depth information can be found in the related content. Assigning a product to a group standard can be very technical, - we can help you do this.

Before you start

You need to know the:

• hazard classification of the product, which can be found on the safety data sheet (SDS)
• exact concentration of all the components of your product
• hazard data, such as toxicity data, of the product or the components.

Step 1: Is your product exempt or excluded from the HSNO Act?

Some products do not need a HSNO approval. They include:

• non-hazardous substances
• substances for use in an exempt laboratory
• radioactive and infectious materials
• foods (but not food additives)
• ready-to-use human medicines.

Step 2: Is your substance a single component chemical or formulated product?

If your substance is a single component chemical you may wish to look at step 7 before proceeding further (unless your substance is a pharmaceutical, pesticide or veterinary medicine active ingredient).

If your substance is a formulated product you may proceed through the other steps.

Step 3: Is there a group standard that fits the use of the product?

If your substance is a formulated product, you need to check that the intended ‘use’ of the product fits in the scope of a group standard. Not all group standards specify a use, some specify a property of the product, such as class 4 substances.

Most hazardous substances will fit in a group standard, unless the substance:

• will be used for biocidal purposes (killing something), including pesticides (herbicides, insecticides, fungicides), vertebrate toxic agents, fumigants, antifouling paints and timber treatments. Veterinary medicines, which include biocidal products such as flea treatments, may fit within the scope of the veterinary medicines group standards.
• is a fuel, including petrol and LPG
• is high hazard
• has an individual approval, these are commonly single chemicals.

If your substance falls within one of these categories, you may need to check whether there is an individual approval that is a better fit.

Step 4: Classifying your product for its HSNO hazardous properties

You can either self-classify your product, or ask us to do that for you.

If the product doesn't trigger any hazard classifications, it does not need approval under the HSNO Act.

Caution: The classification of a product is a very technical process, and you should ensure you fully understand what is involved before you decide to self-classify. We have resources that can step you through this (found in the related content links), but if you are at all uncertain, we strongly advise that you seek independent technical advice, or contact us.

Our Chemical Classification and Information Database (CCID) may provide useful information:

Step 5: Does the product fit the scope of a group standard?

For your product to be assigned a group standard approval, it must meet the scope of the group standard. You will need to know the intended use of the product (step 3) and the hazards of the product (step 4).

The hazard classification of the product must fit with the classifications set out in the scope of the group standard. Certain hazard classifications of a group standard will be mandatory (that is, for a product to be assigned to the group standard, it must have those hazards), whereas other hazard classifications will be optional.

If there is no appropriate group standard available for your product or the hazard classification, you may be able to assign your product to an existing individual approval. If no existing approval for your product exists, you will need to make an application to the EPA.

Step 6: Does the product contain a CMR toxicant?

Some group standards place restrictions on products containing components that are carcinogenic, mutagenic or reproductive (CMR) toxicants.

If your product has any one or more of the following hazard classifications, you must check that every component that gives rise to those classifications is listed on the New Zealand Inventory of Chemicals (NZIoC):

• 6.6A, 6.6B (mutagenic component is present in the product)
• 6.7A, 6.7B (carcinogenic component is present in the product)
• 6.8A, 6.8B, 6.8C (a reproductive or developmental toxicant is present in the product).

If the component is not listed on the NZIoC, then, generally, the product cannot be assigned to the group standard. An exception to this is when an existing product approved under the group standard is being reformulated, and a CMR component is being replaced with another CMR of a lower hazard classification. In this situation, contact us for further advice.

Step 7: Does the product contain a component not on the NZIoC?

Any product that is imported into, or manufactured in, New Zealand for the first time must be checked to see whether it contains a chemical that is not listed on the New Zealand Inventory of Chemicals (NZIoC). A chemical not listed on the inventory is considered to be a chemical that is ‘new’ to New Zealand. Looking up using the Chemical Abstract Service (CAS) number is advisable.

Single chemical

No single component chemical can be assigned to a group standard approval unless that chemical is on the NZIoC.

If your substance is a single component chemical, you must check to see that it is listed for use as a chemical in its own right on the NZIoC. If it is you can use a group standard approval.

If your chemical is not on the NZIoC, or is listed but for use as a component in a substance approved under a group standard only, you must contact us for further advice.

Mixture

If the product does not contain a ‘new’ chemical, then it can be assigned to the group standard. A record of that assignment must be kept.

If your product contains a ‘new’ chemical, then, you must notify us by using the notification form.

Application for Notification of New Chemical Components approved under Group Standards (DOCX, 447KB)

Once we've been notified, the product can be assigned to the group standard and it becomes a HSNO approved substance under that group standard.

Most, but not all, group standards contain this notification requirement for new chemicals. See the group standard to find out if it contains the notification condition.

Step 8: Keeping a record of the self-classification and group standard assignment

Once a product has been assigned to a group standard, you must keep a record of the self-classification and assignment and it must be available for inspection at the request of a HSNO enforcement officer. The record must contain sufficient information to allow for third party verification of the product classification and group standard assignment.

Record of Group Standard assignment (DOC, 421KB)

Once the importer or manufacturer has assigned a product to a group standard and completed the record, there is no need to notify the EPA. A copy of the record does not need to be provided to the EPA.
