Formulation types

1. What is this Guideline about?

  1. This Guideline is made pursuant to section 6A of the Agvet Code.
  2. The purpose of this Guideline is to set out, for agricultural chemical products, formulation types recognised by the APVMA pursuant to regulation 3 of the Agvet Regulations.
  3. Formulation type for an agricultural chemical product comprises a formulation code and description. Formulation type is a prescribed particular for a chemical product (reg 16(da) of the Agvet Regulations).
  4. The formulation types for agricultural chemical products recognised by the APVMA are:
    1. those specified in the Schedule to this guideline (grouped in tables according to general descriptions set out as the heading to each table); or
    2. if not specified in the Schedule to this guideline, the formulation types specified in the Manual on development and use of FAO and WHO specifications for pesticides (the FAO/WHO Manual), prepared by the ‘FAO/WHO Joint Meeting on Pesticide Specifications’.
  5. Consequently, if the formulation type for your proposed agricultural chemical product does not match a formulation type set out in the Schedule to this guideline, you may be able to rely on a formulation type specified in the FAO/WHO Manual.
