I want to vary my product to make a change to the product formulation
Changes to the formulation of an agricultural or veterinary chemical product may be required for a variety of reasons, including the availability of excipients or changes to the purity of the source of active used in the formulation.
All variations to approved product formulation details require an application to be made. The level of information supporting the variation and the assessment required will vary according to the proposed change and significance it may have with respect to ensuring the continued safety and efficacy of the product.
Depending on the change the following registration pathways may be utilised:
- Item 12: No data of a technical nature is required—this application type is used when the change is minor and does not affect the physico-chemical properties of the product.
- Item 13A: Prescribed variation—changes to non-active constituents (excipients) in certain limited circumstances.
- Item 14: Technical modular application—all applications that are not Items 12 or 13A.
Most formulation variations are likely to be made as Item 14 applications. Applicants should familiarise themselves with the scope of each of these pathways and select the pathway which is most appropriate for the formulation change being sought.
This guidance does not cover changes to use patterns, or to the frequency or rate of application. This information is provided in other tailored guidance pathways.
