Examples – Type 14 – Item 14 (Ag): Scenario 3

Scenario 3: Application to vary a product formulation to substitute a solvent for a solvent in a schedule of the Poisons Standard


An applicant applies to vary the formulation of a registered insecticide to substitute one excipient solvent for another. The new solvent is a scheduled poison (schedule 6 of the Poison Standard) and is known to have health risks to humans that must be considered. A new constituent statement, safety directions, first aid instructions and re-entry periods may be required. The product does not have any registered aquatic uses, so an environmental assessment is not required.

Application type

This application is considered under a technical variation (Item 14) as evidence is needed to demonstrate that if the formulation is changed, the product will continue to satisfy the safety, efficacy (including crop safety) and trade criteria.

As the formulation change will result in changes to the relevant label particulars, an updated label must be included in the application.

The following table examines each assessment module and provides an explanation of what modular assessments, levels, timeframe and associated fees are likely to apply to this extension. Modules 1, 11 and 12 are mandatory modules for this application. Considerations are necessary for Modules 2–10 for this variation.
