Class determination

A class determination tells you the regulatory status of a trade name product (TNP) under the Agricultural Compounds and Veterinary Medicines (ACVM) Act 1997.

It is a process to determine whether a TNP requires registration before it can be imported, manufactured, sold or used in New Zealand. Generally, products that meet the definition of an ‘agricultural compound’ in the ACVM Act (provided at end) must be registered unless they fit one of the exempt categories.

You can do your own class determination using the information in Products regulated under the ACVM Act or you can have us do it for you (fees apply). Each class determination may take up to 15 working days for us to complete.

To apply for a class determination, follow the guideline, fill out the application form, and send it to us with the product label and the required fee.

After a class determination is made

You will receive a Class Determination Outcome Letter advising you of the decision made. All decisions are final and valid for three years.

If your product requires registration, relevant information, including registration packages, can be obtained from our website.

If your product does NOT require registration and is imported, your Outcome Letter can be presented to MPI Biosecurity New Zealand at the border to allow release of product under the ACVM Act.  Note that Biosecurity clearance and/or HSNO approval may be necessary before your product can be cleared for entry into New Zealand. You should contact MPI Biosecurity and/or the Environmental Protection Authority (EPA) for further information.
