Understanding the Windsor Framework: New Parcel Regulations from May 2025

The Windsor Framework, a post-Brexit agreement between the UK and the EU, is set to introduce new regulations for parcels moving from Great Britain (GB) to Northern Ireland (NI) starting May 1st, 2025. These changes aim to streamline trade while ensuring compliance with EU customs rules.

Key Changes for Parcel Shipments

The new rules depend on whether the sender and receivers are businesses (B2B) or individuals (B2C, C2C, C2B).

Business-to-Business (B2B) Shipments

• Green Lane Shipments: For goods staying in NI and qualifying under the UKIMS, businesses must register for a UKIMS number and provide it to their carrier.
• Red Lane Shipments: Goods "at risk" of moving beyond NI require a full customs declaration and may incur EU duties.

Business-to-Consumer (B2C), Consumer-to-Consumer (C2C), Consumer-to-Business (C2B) Shipments

• No individual customs declarations required.
• Senders must provide their carrier with:
  • Number of items
  • Product description
  • Total value of the shipment
  • Total weight of the shipment

Why These Changes Matter

The Windsor Framework replaces the Northern Ireland Protocol, which had caused logistical and political challenges since Brexit. By introducing a dual-route system, it aims to reduce paperwork for trusted traders while maintaining regulatory alignment with the EU.

​However, some critics argue that the framework still imposes bureaucratic hurdles on businesses, particularly those sending parcels across the Irish Sea. The requirement for customs declarations on B2B shipments has been described as tightening the "noose" of the Irish Sea border.
