Sending Parcels to Northern Ireland: What the Windsor Framework Means
The rules for sending parcels from Great Britain to Northern Ireland changed under the Windsor Framework, with new arrangements from 2025. Here's a plain-English guide to what changed, who needs a customs declaration, and what — if anything — you pay.

Do you need a customs declaration to send a parcel to Northern Ireland?
For most people, no. Under the Windsor Framework, a parcel sent from Great Britain to a private individual in Northern Ireland for personal use needs no customs declaration from you. Your parcel carrier collects basic information — the recipient's name and a short description of the goods — and handles the rest. Gifts sent between private individuals are treated the same way.
The main exception is business-to-business parcels: to avoid full customs declarations and duty, either the sending or receiving business must be registered with the UK Internal Market Scheme (UKIMS). More on that below.
What is the Windsor Framework?
After the UK left the European Union, the Northern Ireland Protocol was introduced to manage trade between Great Britain and Northern Ireland — which, unlike the rest of the UK, stayed aligned with EU single market rules for goods. In 2023, the Protocol was replaced by the Windsor Framework: a simplified set of arrangements designed to keep goods moving smoothly between Great Britain and Northern Ireland while avoiding a hard border on the island of Ireland.
From 2025, new parcel arrangements under the Windsor Framework came into effect. They draw a clear line between parcels going to ordinary consumers (made much simpler) and parcels moving business-to-business (which use a trusted-trader process). The aim is that everyday online shopping into Northern Ireland feels much like the rest of the UK.
The three ways a parcel can travel from GB to Northern Ireland
1. Business to consumer (a shop sending to you)
When a GB retailer sends an online order to a private individual in Northern Ireland for personal use, no customs declaration is required from the customer. The carrier collects basic commercial information about the parcel. For you as the shopper, ordering to a Northern Ireland address should feel like ordering anywhere else in the UK.
2. Consumer to consumer (sending a gift)
Parcels sent between private individuals — for example posting a gift to family in Northern Ireland — do not need a customs declaration. You hand the parcel to your carrier as normal and provide a description of the contents if asked.
3. Business to business (commercial goods)
Sending goods to a business in Northern Ireland is where the rules are stricter. To avoid completing a full customs declaration or paying duty, either the sending business or the receiving business must be registered with the UK Internal Market Scheme (UKIMS). UKIMS lets trusted traders declare goods as "not at risk" of entering the EU — and if the goods qualify, customs declarations and duty are avoided. Registration takes time, so businesses are advised to apply well before they need it.
Northern Ireland vs the Republic of Ireland — a crucial difference
This trips a lot of people up, so it's worth being precise. Northern Ireland is part of the United Kingdom. The Windsor Framework rules above apply to it, and a Northern Ireland address is a UK address with a BT postcode.
The Republic of Ireland is a separate country and an EU member state. It is not covered by the Windsor Framework. A parcel sent from Great Britain to the Republic of Ireland is an import into the EU — so Irish VAT (23% standard rate) and, on higher-value orders, customs duty may apply, and the parcel can be held for customs clearance. Low-value and second-hand goods are often unaffected, but the rules are genuinely different from sending to Northern Ireland.
If your real goal is to buy from UK shops and receive the goods in the Republic of Ireland, that is exactly what PostUK is built for — see shipping to Ireland from the UK and how a UK address for Ireland works.
What do you actually pay?
- GB to Northern Ireland, personal parcels: no customs declaration and, for qualifying personal-use goods, no customs duty. You pay the normal postage your carrier charges.
- GB to Northern Ireland, business-to-business: no duty if the goods qualify as "not at risk" and a business in the chain is UKIMS-registered. Otherwise standard customs processes and any applicable duty apply.
- GB to the Republic of Ireland: treated as an EU import. Irish VAT and possible customs duty (on orders over €150) may be charged to the recipient, separate from postage.
Rates and thresholds change. Always confirm the current position on gov.uk — search "Windsor Framework" and "internal market movements from Great Britain to Northern Ireland" — and check your carrier's specific process before you ship.
Getting ready for the new rules
- Individuals: there's little to do — personal parcels to Northern Ireland need no customs declaration. Just give your carrier an accurate description of the contents.
- Businesses shipping to Northern Ireland: apply for UKIMS as early as possible, and confirm your goods qualify as "not at risk" of entering the EU.
- Everyone: talk to your parcel carrier about their updated process, and check gov.uk for the latest detail before relying on any single summary — including this one.
Where PostUK fits in
PostUK is a parcel forwarding service based in Northern Ireland. We're not a courier and we don't handle business customs brokerage — what we do is give shoppers a real UK delivery address so they can buy from UK retailers that won't ship internationally, then forward those parcels onward.
That matters most for customers in the Republic of Ireland: you get a UK address, shop any UK store, and we forward your parcels from our Northern Ireland base to your door. Because there's no hard customs border between Northern Ireland and the Republic, the onward journey avoids the queue a parcel sent direct from Great Britain can face — although any Irish VAT or duty that applies on EU import remains the recipient's responsibility.

FAQs — sending parcels to Northern Ireland
Do I need a customs declaration to send a parcel to Northern Ireland?
Not for personal parcels. Under the Windsor Framework, a parcel sent from Great Britain to a private individual in Northern Ireland for personal use needs no customs declaration from you — the carrier collects basic information. Business-to-business parcels are different and may require UKIMS registration to avoid declarations and duty.
What is UKIMS?
UKIMS is the UK Internal Market Scheme. It lets authorised, trusted traders declare goods moving from Great Britain to Northern Ireland as "not at risk" of onward movement into the EU. If goods qualify, the business avoids full customs declarations and duty. It mainly matters for business-to-business shipments, not ordinary consumer parcels.
Is Northern Ireland the same as the Republic of Ireland for parcels?
No. Northern Ireland is part of the United Kingdom and is covered by the Windsor Framework. The Republic of Ireland is a separate country and an EU member state, so parcels sent there from the UK are EU imports and may attract Irish VAT and customs duty. Always check which one you're sending to — the rules are different.
Will I pay duty sending a gift to Northern Ireland?
Gifts sent between private individuals from Great Britain to Northern Ireland do not need a customs declaration and, for qualifying personal-use goods, no customs duty applies. You provide a description of the contents to your carrier if asked.
Does Amazon and other UK retailers deliver to Northern Ireland?
Northern Ireland is part of the UK, so most UK retailers deliver there using a standard BT postcode. Some retailers surcharge or restrict certain items to Northern Ireland addresses. If a UK shop won't deliver to the Republic of Ireland at all, a UK forwarding address is the usual workaround — see our shipping to Ireland guide.
Where can I check the official rules?
On gov.uk. Search "Windsor Framework" and "internal market movements from Great Britain to Northern Ireland" for current, detailed guidance, and check your parcel carrier's own process. Rules and thresholds can change, so treat any summary — including this page — as a starting point.
