The Applicant Guide: Submitting additional data and/or information mid-evaluation

A request to make a minor change to an application once it has been accepted is only acceptable if it falls within the criteria below, and the overall scope of the original application cannot be changed. We consider such changes on a case-by-case basis; and the decision will depend on the stage we have reached with the evaluation of your application. You may also be asked to submit additional data mid-evaluation or as the second part of a 'two-stage' procedure to allow us to complete the evaluation of your application.

Changes to applications ('add-tos')

We will consider changes in the following cases:

Examples of acceptable changes are:

  • changes in product name, authorisation holder and marketing company. If access to third party data is required, new letters of access that reflect the proposed change must be submitted. This change can be made up to the issue of an authorisation
  • a two-year storage stability study that supersedes a previously submitted accelerated or one-year study (only accepted prior to the start of the evaluation of the application by the chemistry specialist assessor)
  • revised labels that do not extend the scope (meaning what the application is for) of the application. These must be submitted before the start of the evaluation of the application
  • additional convenience tank-mix recommendations supported by a Compatibility Assurance Statement (CAS). These may be accepted at any time as the CAS refers to an attached list of tank-mixes and no new label is submitted (see the guidance document on tank-mixes)
  • additional tank mix recommendations supported by data - only accepted before the start of the of the application by specialist assessors
  • minor formulation changes where new data are not required to support the change. Health and safety data sheets and a reasoned scientific case to support the change must be submitted (only accepted before the start of the evaluation of the application by specialist assessors)
  • revised efficacy or residues overviews as long as they do not extend the scope of the application (only accepted before the start of the evaluation of the application by specialist assessors)

But we will not consider the following changes:

  • Any changes that would extend the scope of the application or alter it beyond what was requested when the application was submitted. Examples of altering the scope include requesting authorisation for additional crops; requesting an increase in the application rate, the number of treatments, or shortening the harvest interval; amending the classification of a proposed formulation
  • If the evaluation of the application is nearing completion so that it is no longer possible to consider your add-to request without a new evaluation, for example we will not accept a revised efficacy overview if the efficacy evaluation for your application has been completed

When can additional data or cases be submitted during the course of the application?

Additional data and/or cases can be submitted during evaluation to address any concerns raised that would result in the application being refused if they were not addressed (the 'data mid-evaluation' procedure).

These can only be accepted if additional information has not already been requested for your application in that risk assessment area, and where the scope of your application has not been changed. For example,  data or case supporting an additional use or claim, or a change in GAP (good agricultural practice), would not be accepted.

An additional fee will be charged to cover the cost of evaluating the additional data or case, based on the modules that need evaluating (see the guidance document on application fees).

Individual studies that need consideration in more than one risk assessment area will not be accepted. For example environmental data on pesticide levels in water requiring evaluation by both our ecotoxicology and environmental fate and behaviour specialist assessors could not be accepted. However, we will accept separate studies requiring consideration in more than one risk assessment area. For example three ecotoxicology studies and one residues study, and we would charge the appropriate specialist data fee modules for these.

You will usually have thirteen weeks to respond to requests for additional information; unless we have multiple requests in which case the time given will be shortened. Additional studies should not be started if they will take longer than the deadline given to respond to the request for additional information. Note that the maximum total time you can have to respond to the collective requests for additional information must not exceed twenty-six weeks.

Please note that the acceptance of additional data is entirely at our discretion and the submission of any additional data will not guarantee the successful evaluation of your application.
