Links to specific sections:


Is there a covering letter which clearly summarises the application? Guidance at The Applicant Guide: What should I include in an application?
Is there an application form? Guidance at: The Applicant Guide: What should I include in an application?
Are full formulation details present in the application form? Guidance at Data Requirements: Physical and Chemical Properties. Note for re-registration applications that these details are required in all cases.
Does the formulation contain an unacceptable co-formulant? Refer to the unacceptable co-formulants register. Formulations containing unacceptable co-formulants cannot be authorised.
Are the formulation details complete and expressed in the correct units? For example, are all the tradenames, chemical names and CAS numbers present in the application forms? Concentrations for liquid formulations should be presented in g/l or w/v (not w/w). Please ensure that the formulation details are the same as in Part C of the draft Registration Report (dRR).
Have full details of the proposed packaging been included? For layered packaging materials, please make it clear which layer is in contact with the product. Please check the packaging on the application form and within the dRR are the same.
For refillable/returnable packaging, have you provided details on how the product will be returned, cleaned, and so on, as well as details of whether it is a top mounted discharge valve for bulk containers? Have you provided the appropriate labelling advice? Guidance at Pesticide containers: guidance on operator exposure considerations
Is there a draft label? Guidance at: Labelling Handbook contents
Is there an application overview? Guidance at: The Applicant Guide: General information on completion of the application overview
Is there a draft Registration Report? Guidance on the draft Registration Report
Have you made reference to the fact that further studies/trials reports will be available shortly? All the data to support the application must be present from the outset and cannot be submitted later. You will need to decide whether you wish to continue with this application using only the existing data. The alternative is to delay the application until more trials/studies are available.
Have you included draft reports/studies as part of your submission? This is not acceptable and we will only consider that the application is complete and ready for acceptance once the final trials/study reports are submitted. Please wait until these are available before submission.
Are there discrepancies in the proposed GAP between the draft label/dRR Parts A and B? Ensure that the correct GAP is clear and that it includes clear details of the earliest time of application to be considered for assessment.
Are the proposed formulation details different from those currently authorised? If there are then explain your proposed formulation change.
Have you asked that your application be supported by the use of data for which the protection period has expired for unnamed GB products? You must give full details of any GB/NI products (including MAPP numbers) where you wish to access unprotected data and detail how they support your request. Note you can only make reference to one product, for guidance see The Applicant Guide: The Protection of Data.

Is the application for mutual recognition? Relevant in Northern Ireland
Have you supplied all the relevant supporting documentation, for example, a copy of other MS label and authorisation along with translation into English? Have you confirmed that the formulation and technical specification are the same for the NI  and other MS product? Is the other MS assessment to uniform principles using the agreed Annex I endpoints? Have you supplied a Part A and relevant NI addenda, for example, non-dietary human and consumer exposure, environmental fate and ecotoxicology?
For guidance see The Applicant Guide: Zonal Authorisations and Mutual Recognition under Regulation EC 1107/2009.
Is the application for re-registration? If so, does it include a formulation change or new uses? If it does, detail the changes and how they are supported.
Was the formulation and/or uses considered in the DAR or has it been subject to a previous uniform principles assessment? Give details of any previous assessments, for example, COP number, product name.
Are there any confirmatory data requirements? Please detail whether the inclusion is subject to confirmatory data requirements.
Are all SDSs in accordance with our toxicology guidance? If it is not possible to obtain an SDS less than 2 years old from the revision date and in EU format, please detail this in the application overview and provide evidence from the supplier that this is the most recent SDS and is an accurate description of the current classification.
Have you explained how each area of the assessment is being approached, for example, by data/case or reference to a previous assessment and highlighted any salient points? Detail this in the application overview.
Have you explained the basis for end points used in your risk assessment (particularly if different to those detailed in the EFSA conclusion)? If you are not using the Annex I agreed end points please explain how your proposed end points are supported (for example, new studies which require evaluation or reference to applications where the revised end point has previously been accepted). Where new data/information have been submitted, you should justify why the new data/information are required. This is particularly critical for the fate and behaviour area of the risk assessment.
Are all sections of the dRR in Word format? You may submit PDF versions, but if you do, we additionally require Word document versions.
Have you considered the outstanding areas/data requirements highlighted at active substance approval? Please consider these previously identified issues and determine whether they are relevant to your application. Please provide details as to how these have been addressed or are not relevant in the application overview.
Have you included original copies of all necessary letters of access? Please ensure that data access is clearly explained. If you are relying on letters of access that were submitted previously or are due to follow, please explain this. For previously submitted letters of access detail the date and application they were previously submitted for.
Does your product contain a candidate for substitution? Please ensure that you include a comparative assessment and substitution in line with the guidance Guide for UK applicants for Plant Protection Product authorisation.  


Have you included monitoring methods to support the proposed crops (for example, high water, high acid, high oil and dry commodities), products of animal origin, environmental matrices (soil, water and air) and body fluids and tissues in accordance with SANTE /2020/12830, rev1 in the dRR? Please provide these, if applicable. Details of the residue monitoring methods available for all crop groups being supported, products of animal origin, environmental matrices (soil, water and air) and body fluids and tissues should be summarised. Where a method is not required, a reason should be stated.
Note: Reference should be made to the monitoring methods available in a uniform principle assessment (for example, considered for the approval of the active in the DAR).
There is no need to re-summarise methods that have been fully considered and accepted in a previous uniform principle assessment and only new methods and validation data, when they are required, should be summarised.
Section 5 of part B of the dRR is for monitoring methods only. Pre-registration methods should be summarised in the appropriate section of the dRR alongside the study in which they have been used to collect data.
Have all the relevant properties been determined for the formulation type? Ensure this is clear in the dRR.
For annex point IIIA 2.7 have all the relevant properties been determined before and after storage and have these been fully summarised? Ensure this is clear in the dRR.
Are the ambient storage data sufficient to support the proposed packaging? Note: For liquid formulations this should take into account if it is solvent- or water-based. For solid formulations sold in flexible packs the impact of storage under pressure should be addressed.
Are there any relevant impurities present in the formulation? Do these impurities need to be determined on storage and are fully validated methods of analysis available? The validation data should comply with SANCO/3030/99 rev5.
For technical equivalence evaluations, have you provided full name and address details for the applicant, manufacturer and the location of the manufacturing plant?
  • Full name and address details of the applicant
  • Full name and address details of the manufacturer
  • Full name and address details of the location of the manufacturing plant
Have you included the proposed technical specification either in the HSE application form, dRR Part C or a technical equivalence report? The specification details must also include the following information for the active and impurities:
  • Full chemical names
  • ISO name for active
  • CAS numbers
  • CIPAC number (active only)
  • Molecular weights
  • Molecular formula
  • Molecular structures
  • Min level of the active
  • Max level for impurities, inactive isomers and additives

For standalone technical equivalence applications, the application form CRD8 must be completed.

Have you included a method of manufacture that includes a chemical reaction scheme and brief details (including reaction conditions, temperature, and so on) for each step? The method of manufacture should include a list of the starting materials, including process solvents used in the manufacture, along with details such as:
  • Purity of all the starting reagents and process reagents
  • Maximum levels of impurities present in the starting materials where applicable (for example, dioxins, furans, nitrosamines)

A statement on the commercial availability of each of the starting materials is also required.

Have you included the following details of the batches?
  • Dates of manufacture
  • Batch weights
All representative batches should have been produced within the last 5 years of manufacture. If batches from the last 5 years are not available, a statement is required to confirm that they are still representative of the manufacturing process along with confirmation that no changes to the method of manufacture, including the purity of the starting reagents used, have been made.
If any changes have been made, a case to demonstrate they are minor and will not impact on the analytical profile of the batches must be made.
Batches should not be produced consecutively, in other words, they should be representative of different production runs.
If batch sizes are particularly small, then a case confirming that the batches are still representative should be submitted.
Consideration should be given to what solvents are used in the manufacturing process, and whether they are predicted to be in the final material, and therefore should have been analysed.
Quality Control (QC) data can be used to support the specification, or support claims that the batches are representative.
Is the batch analysis study done to good laboratory practice (GLP)? A GLP batch analysis study must include:
  • A signed and dated GLP and Quality Assurance (QA) statements
  • A GLP certificate

The certificate must cover analytical chemistry and the date of the certificate must cover the date of the batch analysis study.
For countries that are not signed up to the Organisation for Economic Co-operation and Development (OECD) or MAD (mutual acceptance of data) scheme, for example, China, then the GLP certificate must be provided by a country that is.

Have you included a statement on how the confirmation of the identity of the active and impurities was addressed? Guidance on Technical equivalence can be found in SANCO/10597/2003– rev. 10.1

Mammalian toxicology

If extrapolations have been relied upon are these clearly stated on a crop by crop basis? Extrapolations must be in accordance with residues guidance.
For any new residue trials data are the details of the supporting methods of analysis outlined in Section IIIA 8.3? An appropriate reference to a Uniform Principles assessment of validation data for an appropriate crop matrix must be made or the details of the new validation data must be summarised. See methods of analysis guidance for further information.
If relevant, has a specific dietary burden for livestock (with clearly defined input values) been presented and compared to the feeding studies to assess the residues that may arise in products of animal origin for the proposed uses? See Residues guidance for further information.
Has the need for processing data for each crop been assessed? Where data are required a clear reference to the source of the available data must be given.
Do the available rotational crop data cover the crops and maximum application rate for the proposed uses? See Residues guidance for further information.

Environmental fate guidance
Have you supplied environmental exposure calculations using GB/NI specific methodology to support the GB/NI authorisation? Details of environmental fate and behaviour data requirements can be found at:
Environmental fate guidance
Have you stated whether any precedents are being relied upon to address environmental exposure? Please note that precedents set under COPR are unlikely to be appropriate for post Annex I inclusion authorisations.
Have you have submitted new environmental fate data and/or modelling? You must clearly explain why you are submitting this; new Annex II data in particular need to be explained.


Is more than 1 active present in the formulation? Is a consideration of combined toxicity provided? This is required, see Ecotoxicology Guidance pages.
Are you are extrapolating from other products that your company owns? Have you explained the formulation details of those products and the impacts of any differences from an ecotoxicology perspective? Address this in the dRR and/or application overview.
Is there a GB/NI specific aquatic risk assessment (spray drift and drainflow) provided for the crop(s)? Include this in the dRR.
Has a risk assessment for non-target plants been provided? Include this in the dRR.
Are you submitting new vertebrate data? Please ensure that you have provided a justification for these data in line with Regulation  (EC) 1107/2009, Article 33/3c.


Do any of your proposed target pests occur/are considered to cause economic damage warranting control measures?
Are the targets not considered to be pests warranting control under GB/NI conditions?
Are all the crops considered to be commercially grown in the GB/NI?
If not please provide further justification supporting the need for control.
If so, you may wish to submit additional justification and evidence.
If not then you may wish to submit additional justification and evidence with this application to explain the relevance of the crop to the GB/NI.
Is this application for the re-registration of an existing GB/NI product following completion of the review conducted to 91/414 standards? If so, please see Efficacy guideline 103 which details the requirements and approach. You are required to provide an explanation comparing the proposed label uses to the relevant existing GB/NI product, including highlighting any proposed changes: changes in GAP, new uses, existing uses no longer being supported.
Does your application include in the Biological Assessment Dossier (BAD) or dRR data generated outside GB/NI? Please provide justification for the relevance of the data to GB/NI conditions (see 'Chapter 8' of the 'Data Requirements Handbook' for more details).
Does your application address the outstanding COPR efficacy data requirements? If not provide an explanation for this omission.
Do your BAD/dRR proposed uses differ from those on the draft label/application overview, in particular for changes in rates, targets, references to using unprotected data including different named products? Is any intention to use a bridging approach clearly explained? If so, explain why or correct this.
Applications for GB only authorisation:
Does your BAD/dRR include trials that have used reference products not authorised in Great Britain?
You must provide the relevant translated labels. This can be either the whole label, or the relevant sections for the particular target in the trials. This information is required to determine the relevance of the reference products, whether it is authorised for the target and has been used at the authorised rate where data were generated.
Does your BAD and/or dRR encompass all of the uses specified in the GAP table and/or proposed label? Ensure that the BAD and/or dRR include this information/data.
For NI mutual recognition applications:
Does your application include evidence that the agricultural, plant health and environmental (including climatic) conditions relevant to the use of the product in the other MS are comparable to those in Northern Ireland?
Ensure that your BAD and/or addendum to the dRR contains this information.
Does your application include information to indicate the levels of performance of the product against the relevant target pests? Great Britain/Northern Ireland operate a system of tiered claims depending on the level of control provided. Ensure that you provide a summary of the level(s) of control achieved so that your prod's performance can be aligned with the current GB/NI labelling system.
For NI mutual recognition applications: Where the label in the other MS claims control for a group of pests (for example, aphids, caterpillars) have you provided information on which species were tested? Where appropriate also include information on the relevance to Northern Ireland of the species tested.
Does your BAD/dRR include information on the Official Recognition status of all the testing organisations and relevant Official Recognition Certificates? Note: for GB/NI organisations, reference to the relevant ORETO number is sufficient.
Does your BAD/dRR address all the Regulation (EC) 1107/2009 efficacy data requirements? Ensure this is included in the BAD/dRR.
Are the summary tables in an appropriate format with sufficient detail for an evaluation to be conducted? Please ensure that they are. You are referred to the ECPA Technical guidance paper No. 2011/1 'Technical guidance for applicants in preparing a concise efficacy summary' as part of a draft registration report (dRR)' which provides guidance on the information and the level of detail required.
Is the summary of the efficacy data in an appropriate format? You may either use a dRR Section 3 to submit and summarise all data and relevant appendices, or submit a Biological Assessment Dossier (see Efficacy Guideline 101) and then use the dRR template to provide a concise summary.

In addition to the checklist above, you may also wish to consult the ecotoxicology and environmental fate lists of common reasons for requests for further information.
