Introduction

The Windsor Framework, agreed on 27 February 2023, includes a new set of simplifications to allow the smooth movement of goods within the United Kingdom (UK) internal market. These simplifications have been designed to allow you to move goods from Great Britain (GB) to Northern Ireland (NI) that are remaining in the UK internal market, without having to complete full international customs declarations and instead provide commercial information about your goods. For further details on the Windsor Framework, see An overview of the Windsor Framework on NICTA.

This guide introduces the simplified processes for Internal Market Movements as part of the Windsor Framework implementation, the requirements for using these processes and the types of movements available in the Trader Support Service (TSS).

This guide does not cover other NI goods movement options available in the TSS Portal, such as the two-step customs declaration process known as the TSS Simplified Procedure or the Full Frontier Declaration journey. For more details on other NI goods movements available on the TSS Portal, see NICTA.

What are the simplified processes for Internal Market Movements?

The simplified processes for Internal Market Movements contain a range of facilitations to ease the process of moving goods ‘not at risk’ of entering the European Union (EU) (parcels and freight) from a business in GB to a business in NI. These processes include:

  • A simplified dataset known as the Internal Market Movement Information (IMMI)
  • A Trader Goods Profile (TGP) to support the completion of IMMI
  • A new Entry in Declarant’s Records (EIDR) authorisation, available to traders authorised under the UK Internal Market Scheme (UKIMS), known as UKIMS-EIDR

Goods movements using the simplified processes for Internal Market Movements:

  • Are not subject to the same processes that apply to goods ‘at risk’ of entering the EU, entering NI. ‘At risk’ goods are those that enter NI but may later be sold or consumed in the EU. More information on moving ‘at risk’ and ‘not at risk’ goods can be found on GOV.UK
  • Only need to submit commercial information

There are existing schemes like the Northern Ireland Retail Movement Scheme (NIRMS) and the Northern Ireland Plant Health Label (NIPHL) scheme that can be used alongside the simplified processes for Internal Market Movements.

Simplified processes for Internal Market Movements

Internal Market Movement Information (IMMI)

This form replaces the requirement for submitting a customs declaration and instead allows you to record the movement of your goods using a simplified dataset.

The information required is significantly less than that required for the movement of ‘at risk’ goods, and you can use IMMI before the goods are due to move (pre-movement) or when the goods have arrived (post-movement). This provides flexibility to use the varied movement options most suited to your business model.

If your goods are already in NI under certain customs special procedures and you meet the criteria to use the simplified processes for Internal Market Movements, you can use IMMI to divert those goods to free circulation in NI.

The movement options using IMMI are detailed in the Movements available using the Internal Market Movement Information (IMMI) section of this guide.

The use of IMMI is available to all traders who meet the conditions listed in the Conditions for using the simplified processes for Internal Market Movements section of this guide.

Traders who are unable to meet the conditions to use the simplified processes for Internal Market Movements can continue to use the TSS Simplified Procedure or the Full Frontier Declaration journey for movements into NI, as stated in the introduction to this guide.

Trader Goods Profile (TGP)

As part of the service from HM Revenue & Customs (HMRC) to support the simplified processes, the Trader Goods Profile (TGP) is a unique goods profile that HMRC will populate with the relevant trade information, including the commodity code for goods you have historically moved. It is available via the Government Gateway and on your TSS account.

TGP functionality is available to use within the IMMI and the information within the TGP can be auto-populated by simply typing the good’s description or selecting the good from the available list. This tool minimises your requirement for manual entry on IMMI.

You will need to provide permission for TSS to access your TGP from the Government Gateway, with TSS functionality allowing you to create and manage entries within your TGP. For further details see the Trader Goods Profile (TGP) Guide on NICTA.

UKIMS-EIDR

If you are UKIMS authorised, you can apply for a new HMRC authorisation for EIDR specifically for use on internal market movements. For further details on when EIDR can be used and how to apply, go to UKIMS-EIDR on GOV.UK

Note: If you are using TSS, you do not need to apply for a UKIMS-EIDR authorisation as TSS already supports EIDR. TSS does not currently support the use of UKIMS-EIDR authorisation. Should you wish to use your UKIMS-EIDR authorisation, you can do this outside of TSS.

Conditions for using the simplified processes for Internal Market Movements

To use the simplified processes for Internal Market Movements, the following conditions must be met:

  • You must be authorised under UKIMS
  • Goods must be ‘not at risk’ of entering the EU
  • Goods must be moved by direct transport from GB to NI (including Transit goods, so long as the Transit starts in GB and ends in NI)
  • The goods must be in free circulation in GB prior to movement
  • Goods must not be Category 1 goods (those liable to quotas, anti-dumping duties or trade safeguards and those subject to prohibitions and restrictions)

Categorisation of goods is covered in the What goods can move using the simplified processes for Internal Market Movements? section of this guide.

Responsibilities to consider when using the simplified processes for Internal Market Movements

If you are moving goods from GB to NI using the simplified processes for Internal Market Movements, you or your haulier (or intermediary) should agree who is responsible for the movement and who will be identified as the importer on the IMMI. This includes the UKIMS authorisation used for the goods movements and for ensuring the respective permissions for its use are in place.

Note: If you are an agent or intermediary, you may also be UKIMS-authorised, provided you accept responsibility to be the importer for your trader and the consequent legal liability.

For more information refer to the simplified processes for Internal Market Movements guidance on GOV.UK.

Schemes available for use with the simplified processes for Internal Market Movements

As part of the Windsor Framework agreement, the following schemes were introduced to simplify the process of goods movements from GB to NI.

UK Internal Market Scheme (UKIMS)

This is a trusted trader scheme and is a mandatory requirement for those wishing to use the simplified processes for Internal Market Movements. Traders who are authorised under UKIMS can declare their goods ‘not at risk’ of entering the EU as their goods are for sale to, or final use by, end consumers in UK.

Agents and intermediaries can also hold a UKIMS authorisation, providing that they are willing to act as the Importer of Record on the IMMI and are able to maintain evidence requirements as part of the conditions of the scheme.

For more information on the UKIMS scheme, including how to apply, see guidance on GOV.UK. The NICTA website also contains useful tips, FAQs and a video guide on how to complete the UKIMS application.

Northern Ireland Retail Movement Scheme (NIRMS)

This scheme allows businesses to move pre-packed retail goods that are not intended for onward movement into the EU, from GB to NI, while avoiding extensive and costly certification and assurance processes.

UK public health and consumer protection standards will apply for all retail food and drink moved through the scheme with EU standards, when applicable in relation to animal and plant standards. Under NIRMS arrangements businesses can move goods based on a single General Certificate, supported by a packing list.

For more information on NIRMS and how to register for NIRMS, see guidance on GOV.UK. You can also find an overview of the scheme on NICTA.

Northern Ireland Plant Health Label (NIPHL)

The NIPHL scheme means growers and traders in GB can move certain products into NI without full phytosanitary certification, if they follow NIPHL rules.

Like the UK plant passport scheme, this scheme makes sure checks for pests and diseases are carried out and goods can be traced.

For more information on NIPHL, see guidance on GOV.UK. You can also find an overview of the scheme on NICTA.

UK Carrier Scheme (UKC)

Traders moving consumer parcels from GB to NI may benefit from the UK Carrier Scheme (UKC) under the Windsor Framework arrangements. Consumer parcels are defined as those moving from:

  • Business to consumer (B2C)
  • Consumer to business (C2B)
  • Consumer to consumer (C2C)

Note: If moving business-to-business (B2B) parcels or if the parcel exceeds the weight limit, IMMI should be used instead of the UKC.

Further details about the scheme , how to apply and eligibility, including weight limits on parcels, can be found on UKC guidance on GOV.UK. If goods do not qualify for the UKC, follow the Sending parcels to and from NI guidance on GOV.UK.

What goods can move using the simplified processes for Internal Market Movements?

Most goods can move using the simplified processes for Internal Market Movements, though there are some that are not eligible for these movements. The eligibility for goods to move using these processes is determined by their categorisation.

Goods categorisation

To determine eligibility for the simplified processes for Internal Market Movements, goods have been divided into three categories:

  • Standard goods – all goods (excluding excise) that have no documentary controls and/or have no licensing requirements

Pre-packaged retail food and drink goods that are being moved under a NIRMS authorisation fall into this category. Movements of these goods require a 6-digit commodity code, which can be generated through the TGP (see the Trader Goods Profile (TGP) section of this guide).

  • Category 2 goods – these goods are subject to special health, licensing or environmental controls including excise goods

Goods that are being moved under the NIPHL scheme fall into this category. Movements of these goods require an 8-digit commodity code, which can be generated through the TGP (see the Trader Goods Profile (TGP) section of this guide).

  • Category 1 goods – these are goods that are subject to total bans, prohibitions, trade defence measures such as quotas, safeguarding and anti-dumping duties

Goods that are subject to the excise duty off-set mechanism are also considered as Category 1. The simplified processes for Internal Market Movements cannot be used for goods in this category.

Further details on the categorisation of goods under the Windsor Framework can be found in categorising goods for Internal Market Movements guidance on GOV.UK.

Procedure Codes available for use with IMMI in TSS

The simplified processes for Internal Market Movements are for the movement of free circulation goods from GB to NI for sale or final use by end consumers in the UK internal market. As a result, there is a significant reduction in the number of Procedure Codes available to use on IMMI, which are limited to only those that apply to releasing goods within the UK internal market. This ensures that no additional checks or duties apply to the movement.

The eligibility of the codes depends on which movement type you wish to use. The movement types available for use with the simplified processes for Internal Market Movements are detailed in the Movements available using the Internal Market Movement Information (IMMI) section of this guide.

If moving goods from GB to NI using IMMI pre-movement, the Procedure Codes available to use are:

  • 4000 – Release to free circulation
  • 0700 – Release to free circulation and excise warehousing

An overview of this scenario is also covered in the Pre-movement section of this guide.

If the goods are already in NI and require diversion from a special procedure to free circulation using IMMI post-movement, the available Procedure Codes are:

  • 4051 – Release to free circulation for goods that were previously entered into Inward Processing on arrival in NI
  • 4071 – Release to free circulation for goods that were previously entered into Customs Warehousing on arrival in NI
  • 0751 – Release to free circulation and excise warehousing for goods that were previously entered into Inward Processing on arrival in NI
  • 0771 – Release to free circulation and excise warehousing for goods that were previously entered into Customs Warehousing on arrival in NI

An overview of this scenario is also covered in the Post-movement section of this guide.

Movements available using the Internal Market Movement Information (IMMI) in TSS

Pre-movement

TSS provides the following two options for you to move goods using IMMI so that you can submit details for your goods prior to arrival in NI.

Pre-movement IMMI

This is an Entry Summary Declaration, combined with IMMI, completed as a single submission before the goods are due to arrive:

  • The Entry Summary Declaration contains safety and security information about the goods and is required for all goods movements from GB to NI

In TSS, the Entry Summary Declaration also serves to determine whether the goods are eligible to move using IMMI. For further details, see the Entry Summary Declaration: Step-by-step guide on NICTA.

  • As mentioned above, IMMI contains the commercial information for goods moving directly from GB to NI which are ‘not at risk’ of entering the EU

Legal responsibility for IMMI rests with the UKIMS-authorised party.

Note: No further information is required post-arrival.

Detailed guidance and step-by-step instructions for this movement can be found in the Pre-movement Internal Market Movement Information (IMMI) Step-by-Step guide on NICTA.

If goods are being moved under the NIRMS or NIPHL schemes, additional steps are needed to satisfy requirements under each scheme. You can find more guidance on what you need to do when moving goods using the NIRMS on GOV.UK. If you need more information on what goods can move using the NIPHL scheme and what to include on your NI plant health label, see GOV.UK.

When the pre-movement IMMI is completed, the Movement Reference Number (MRN) generated by TSS must be used to raise a Goods Movement Reference (GMR) on the Goods Vehicle Movement System (GVMS) by either logging in to GVMS on GOV.UK or by using the TSS GMR automation option that is available in TSS.

For details on GMRs and how to generate one, see the Creating a Goods Movement Reference guide on NICTA.

Pre-lodged standalone IMMI

This is where the haulier has completed an Entry Summary Declaration outside of TSS or where an Entry Summary Declaration only has been submitted and a standalone IMMI is completed before the goods are due to arrive.

Note: No further information is required post arrival.

The haulier, trader and agent (or intermediary) can use the pre-lodged standalone IMMI to enter the goods information prior to the movement of the goods from GB to NI.

Detailed guidance and step by step instructions on the pre-lodged standalone IMMI can be found in the TSS Pre-lodged Standalone Internal Market Movement Information (IMMI) Guide.

The MRN from the submitted pre-lodged standalone IMMI must be used when the GMR is raised in GVMS on GOV.UK.

For details on GMRs and how to generate one, see the Creating a Goods Movement Reference guide on NICTA.

Post-movement

TSS provides the following two options for you to move goods using IMMI so that you can submit details for your goods after they have arrived in NI. You do not need to use these processes if you completed a pre-movement IMMI.

Post-movement IMMI as part of the TSS Simplified Procedure

In TSS, IMMI can offer flexibility in when you would like to provide the details of your goods movement.

Using the TSS Simplified Procedure, you can submit an Entry Summary Declaration and an auto-generated Simplified Frontier Declaration to allow movement to NI. Upon arrival, you can use the IMMI and enter the commercial information of the goods rather than submit a Supplementary Declaration by using the conversion of a Supplementary Declaration to the Internal Market Movement Information (IMMI) functionality in TSS, if goods are eligible. See TSS Supplementary Declaration conversion to Internal Market Movements Information (IMMI) Guide on NICTA.

Conversion of a Supplementary Declaration to IMMI in TSS allows you, as part of the TSS Simplified Procedure, to convert the generated Supplementary Declaration into IMMI if your goods qualify and meet the criteria for using the simplified processes for Internal Market Movements. This conversion significantly reduces the number of fields required for completion.

By using IMMI as part of the TSS Simplified Procedure, you can benefit from additional time in providing the final information about your goods. There is no immediate requirement to provide the goods information, and you have until the tenth calendar day of the following month to submit the information.

The goods must meet the conditions for using the simplified processes for Internal Market Movements as previously advised in the Conditions for using the simplified processes for Internal Market Movements section of this guide.

Detailed guidance on using IMMI as part of the TSS Simplified Procedure can be found on the TSS Supplementary Declaration conversion to Internal Market Movements Information (IMMI) Guide on NICTA.

Arrived Standalone IMMI

If you have moved goods from GB to NI and placed them into certain customs special procedures because the end destination of the goods was unknown at the time of movement, you can use the IMMI to divert those goods to free circulation. You can do this by submitting an Arrived Standalone IMMI. See TSS Arrived Standalone Internal Market Movement Information (IMMI) Guide on NICTA.

An Arrived Standalone IMMI is completed to release goods for free circulation (also known as diversions) that have been previously placed under customs special procedure on their arrival into NI and meet the requirements to use the simplified processes for Internal Market Movements.

Diversions can only be supported for goods being removed from the customs special procedures listed below:

  • Inward Processing
  • Customs Warehousing

The goods must meet the conditions for using the simplified processes for Internal Market Movements as previously advised in the Conditions for using the simplified processes for Internal Market Movements section of this guide.

Detailed guidance and step by step instructions can be found in the TSS Arrived Standalone Internal Market Movement Information (IMMI) Guide.

Hauliers moving mixed loads

Hauliers can continue to move mixed consignments of goods that are destined for the UK internal market (using the IMMI) along with ‘at risk’ goods (declared via the TSS Simplified Procedure or the use of Full Frontier Declarations functionality) on a single truck.

How TSS supports the simplified processes for Internal Market Movements

TSS is equipped to provide hauliers, traders and agents (or intermediaries) multiple functionalities to utilise the simplified processes for Internal Market Movements effectively.

The TSS Company Profile

  • You can upload and maintain authorisations, for example, a UKIMS or NIRMS authorisation. These will be auto-populated into the IMMI
  • You can manage your UKIMS and TGP permissions as well as authorise hauliers and agents (or intermediaries) to submit the IMMI on your behalf
  • Hauliers can activate GMR automation and generate GMRs from the TSS Portal without having to go onto the GVMS website

Auto-population of information in IMMI

  • If you have active authorisations for UKIMS and NIRMS, your authorisation details will be auto-populated in the IMMI
  • TSS will auto-populate a number of fields required on the IMMI for a faster user experience

Trader Goods Profile (TGP) access

TSS is integrated with HMRC’s TGP service, and you are able to:

  • Use your TGP entries to populate information into the IMMI
  • Add new entries to your TGP profile directly from TSS rather than navigating away from the TSS Portal to the Government Gateway

How to prepare for using the simplified processes for Internal Market Movements

Considerations for using the simplified processes for Internal Market Movements

All parties involved in the movement of the goods must understand their roles and responsibilities, including the sale and delivery terms of the goods before the movement commences.

It is important that the terms of contract are agreed between the exporter and the importer, even though GB to NI is not an international customs movement and Incoterms® are not required.

You will need to agree who is responsible for the movement, including the holder of the UKIMS authorisation and permissions to use it.

It is important to agree who will be providing the IMMI into the TSS Portal and ensure that the correct EORI is used from the beginning of the process. This must be the EORI associated with the UKIMS-authorised party.

The use of the correct EORI needs to be communicated with the party responsible for submitting the Entry Summary Declaration (in most cases this is the carrier or haulier), so that your goods can be moved using the simplified processes for Internal Market Movements.

The carrier or haulier is responsible for the Entry Summary Declaration, and the UKIMS- authorised party is responsible for the IMMI.

Actions traders need to take

TSS will support you using the simplified processes for Internal Market Movements by using information provided on your Company Profile. The information is used to determine if your UKIMS or TGP can be used when the IMMI is created in TSS.

To move goods using the simplified processes for Internal Market Movements and successfully submit the IMMI using TSS, you must:

  • Upload your UKIMS authorisation details to your TSS Company Profile (step-by-step instructions on how to do this can be found in the How to use the TSS Portal guide on NICTA)
  • Grant access permissions to your haulier or intermediary to use your UKIMS authorisation
  • When a haulier or intermediary starts the IMMI for your goods on TSS, they will only be able to complete it if access has been granted

Step-by-step instructions on how to do this can be found in the How to use the TSS Portal guide on NICTA:

  • Grant permissions to your haulier or intermediary to use your TGP in TSS if you want them to use it when creating an IMMI in TSS
  • If you have registered for a TGP and want to use it, ensure it is maintained with correct and up-to-date information about the goods you move

You can use the Windsor Framework Trader Readiness Questionnaire to check if you are ready for the Windsor Framework processes and see what actions you may need to take.

The Windsor Framework Trader Readiness Questionnaire enables you to check your UKIMS, NIRMS and TGP status through your TSS Company Profile. You can access the questionnaire from your Company Profile in the TSS Trader Technical Readiness for Windsor Framework section at the top of the screen. More information can be found in the How to Use the TSS Portal guide on NICTA.

Actions hauliers and intermediaries need to take

If you are a haulier moving goods from GB to NI using the simplified processes for Internal Market Movements, you need to check and obtain certain information from your customer before the goods movement commences.

To move goods using the simplified processes for Internal Market Movements in TSS, you as a haulier must:

  • Check with the party responsible for the movement (Importer of Record) if the respective consignment should move using the simplified processes for Internal Market Movements
  • Obtain the correct EORI, for which UKIMS is granted, to submit IMMI successfully
  • Ensure you are granted permissions to use the traders UKIMS authorisation when submitting the IMMI
  • Check if you are granted permission to use the trader’s TGP, should the trader wish you to use their TGP when creating the IMMI

Taking the above steps will help you successfully submit an Entry Summary Declaration and IMMI as a single submission in the TSS.

If you do not have the information required to submit the IMMI before the goods move, you can continue to use the TSS Simplified Procedure. The trader can then decide whether to convert the Supplementary Declaration portion of the TSS Simplified Procedure to the IMMI if they can satisfy all the necessary requirements, as mentioned earlier in the Conditions for using the simplified processes for Internal Market Movements section of this guide.
