The Windsor Framework established a new set of arrangements effective 1 May 2025 for the movement of goods via both parcels and freight between Great Britain (England, Scotland and Wales) and Northern Ireland.
What is the Windsor Framework?
On 27 February 2023 the United Kingdom and the European Union agreed the Windsor Framework, providing a fundamentally new set of arrangements in three key areas; restoring the smooth flow of trade within the UK internal market by removing burdens that have disrupted East-West trade; safeguarding Northern Ireland’s place in the Union; and addressing the democratic deficit that was otherwise at the heart of the original Northern Ireland Protocol. These arrangements were adopted at the Withdrawal Agreement Joint Committee on 24 March 2023.
With this new agreement, the UK Government fully preserves its longstanding commitments to ensure Northern Ireland’s businesses have full unconditional and unfettered access to their most important market in Great Britain, while maintaining their privileged access to the whole of the EU market. This new approach, set out in the Windsor Framework, restores the balance needed to uphold the Belfast (Good Friday) Agreement in all its dimensions. It puts in place a new legal and constitutional framework, changing the text of the treaty and scrapping a range of EU rules.
Details about the simplifications available for moving goods within the UK internal market under the Windsor Framework can be found in the Simplified processes for Internal Market Movements – Introduction Guide.

Windsor Framework Glossary of Terms
Please find below a list of key Windsor Framework related terms, their acronyms and associated definitions:
| Acronym | Term | Definition |
|---|---|---|
| SPIMM | Simplified processes for Internal Market Movements | Simplified custom movements available to traders under the Windsor Framework where eligible goods ‘not at risk’ of entering the European Union are moving under UKIMS authorisation from Great Britain to Northern Ireland via direct movement. |
| IMMI | Internal Market Movement Information | Simplified dataset requiring less information to be submitted than a full customs declaration. Internal Market Movement Information can be submitted to the Customs Declaration Service (CDS) through the TSS Portal. To use the simplified dataset, eligible ‘not at risk’ goods movements must be authorised under the UK Internal Market Scheme. |
| UKIMS | UK Internal Market Scheme | HMRC authorisation that allows you to declare eligible goods ‘not at risk’, and not be charged duty, if entering Northern Ireland from free circulation in Great Britain, when brought into Northern Ireland for sale or final use by end consumers in Northern Ireland, and meeting all the other criteria as set out in the guidance. Further details on eligibility and how to use the UKIMS authorisation can be found on GOV.UK. |
| TGP | Trader Goods Profile | A bespoke profile where each trader can hold the data, which can be accessed by intermediaries including the Trader Support Service, on the goods that they regularly move. This allows the completion of Internal Market Movement Information (IMMI) from a goods description with no requirement to provide a commodity code on a per movement basis. |
| NIRMS | Northern Ireland Retail Movement Scheme | A new way to move prepacked retail goods from GB into NI. Goods can move on the basis of a single General Certificate for eligible consignments, supported by a packing list. There is no requirement for an official veterinarian or plant health inspector to approve the documentation. There are further details on the benefits and eligibility requirements of NIRMS registration on GOV.UK. |
| NIPHL | Northern Ireland Plant Health Label scheme | Growers, farmers and other relevant traders in Great Britain can move plant products, used agricultural and forest machinery to Northern Ireland. Goods moving under the scheme have a NIPHL attached and do not require a Phytosanitary Certificate (PC) provided the goods meet the conditions of the scheme and remain in Northern Ireland. Go to Northern Ireland Plant Health Label (NIPHL) scheme on GOV.UK for further details on the benefits, eligibility and registration. |
When did the Windsor Framework come into effect?
The framework was implemented in stages to provide businesses with time to adapt to the arrangements, which became effective from 1 May 2025.
What are the different elements that the Windsor Framework introduced?
The Windsor Framework introduced simplified processes for moving goods from Great Britain to Northern Ireland.
These include:
- Internal Market Movement Information (IMMI), which is a simplified dataset to use when moving goods
- A Trader Goods Profile (TGP) to support completing the simplified dataset
- Applying to use Entry in Declarant’s Records (EIDR) process alongside the UK Internal Market Scheme (UKIMS) authorisation
These can be used when moving goods from a business in Great Britain to a business in Northern Ireland where one of the parties moving the goods has a UKIMS authorisation and the goods meet the criteria to be moved as ‘not at risk’ of entering the EU under the scheme.
Note: other movements of goods to Northern Ireland, such as those destined for the EU, may need full customs processes. You may have to pay the applicable EU rate of duty.
Further guidance about the simplified processes are available in the Simplified processes for Internal Market Movements – Introduction Guide.
Do I need to do anything?
To take full advantage of the various schemes that have been developed as part of the Windsor Framework, you may be required to take some proactive steps. It is therefore essential that you review the associated eligibility criteria to identify whether a scheme is suitable for your specific trade scenario.
To gain access to the simplified processes for Internal Market Movements, you need to be UK Internal Market Scheme authorised. The registration is open. Find out more about the requirements for the scheme.
Any business that is involved in moving retail goods such as food, drink, cut flowers and pet food from Great Britain that will be sold to the final consumer in Northern Ireland should consider NIRMS registration, refer to GOV.UK.
If you are moving plants from Great Britain to Northern Ireland please review the eligibility criteria for the Northern Ireland Plant Health Label (NIPHL) scheme on GOV.UK. This scheme gives growers and traders who meet the requirements a way to move these goods with a NIPHL and without a phytosanitary certificate.
Additionally, TSS have hosted webinars and podcast sessions to support the implementation of the Windsor Framework. Recordings can be found under Webinars and Recordings on NICTA
