New rules after 1 May 2025 - Windsor Framework and TSS in practice..
1 May 2025 brought important changes for businesses operating between the UK and Northern Ireland. New rules arising from the Windsor Framework and updates to the Trader Support Service (TSS) came into full force, introducing simplifications but also specific obligations for exporters and importers.
Windsor Framework - simplifications already in place
Since 1 May, the full categorisation of goods according to three groups has been in place:
Category |
Description |
CN code |
Standard goods |
Without permits and SPS documentation - most consumer goods |
6 figures |
Category 2 goods |
Requires permits, licences, concerning, inter alia, excise duty, plants, alcohol |
8 digits |
Category 1 goods |
Prohibited goods or goods subject to safeguard duties - require full clearance |
10 digits |
Examples of goods "at risk"
- Clothing and footwear imported from outside the UK (without processing)
- Perfumes and luxury cosmetics
- Alcohol and excise products
- Electronics for resale
- Plants without NIPHL authorisation
TSS and NICTA tools - how to make your life easier
- Trader Goods Profile (TGP)
Created by UKIMS-registered companies, it contains a list of regularly transported goods, with assigned category and CN code. Automates IMMI declarations and allows data to be made available to carriers. - Accurate descriptions of goods in TSS
Don't use generalities like 'accessories' - descriptions must include material, purpose, brand, model and volume, among others. - GMR (Goods Movement Reference)
Standard merchandise can have a GMR generated automatically by the TSS portal - without manual input.
NIPHL - Northern Ireland Plant Health Label
Applies to exports of seeds, seedlings and agricultural machinery. Authorisation to use NIPHL labels required.
Operating from GB to NI? Take care:
- Registration of the consignee in the TSS - mandatory for customs declarations
- Consignee registration with UKIMS - to avoid customs duties and benefit from the "green lane"
- Consistent company data across systems
- Cooperation with an authorised carrier - especially for B2C
Reminder:
UK Ltd (a supplier from England) does not need to have UKIMS/TSS if:
- it is the NI buyer who makes the declarations and acts as the importer,
- The company operates on a DDP basis and the paperwork is handled by an agent.
However, if UK Ltd wishes to self-declare goods, it needs:
- EORI number XI
- registration with TSS and UKIMS
Summary of responsibilities - who is responsible for what?
Element | Responsible |
Registration with TSS |
Northern Ireland buyers |
Registration with UKIMS |
Northern Ireland buyers |
Customs declarations |
Buyer or agent |
Payments (DDP) |
UK Ltd |
VAT invoice |
UK Ltd (20% if recipient has no VAT) |
If you are selling to Northern Ireland, now is the perfect time to:
- review its procedures,
- implement TSS and TGP tools,
- take care of the fluidity of supply.
