Shipping to Jersey, Guernsey and the Isle of Man: Customs and VAT Rules for UK Ecommerce Orders

Orders from Great Britain to the Isle of Man are treated as domestic supplies, so you charge UK VAT and ship as normal. Orders to Jersey and Guernsey are exports: you can zero-rate them with evidence, each parcel needs customs data, and Jersey customers may pay 5% GST. Guernsey has no GST.

That difference catches out a lot of UK brands. In August 2026 Not On The High Street paused deliveries to Jersey and Guernsey, saying the customs requirements risked delays and unexpected fees for customers. Jersey Customs told ITV News that nothing had changed in the rules for goods shipped from the UK, and suggested some carriers were wrongly treating Jersey as an international destination. Either way, island customers lost a place to shop. This guide sets out how each island is treated and how to serve those customers without held parcels. It is general guidance, so confirm the detail with a customs broker, a tax adviser or Revenue Jersey before you change your pricing.

Three Places, Three Tax Treatments

The Isle of Man sits inside the UK VAT system, while Jersey and Guernsey sit outside it. HMRC's VAT Notice 703 on goods exported from the UK confirms both points: goods sent from Great Britain to the Isle of Man are domestic supplies, and the Channel Islands are not part of the UK for VAT purposes.

• Isle of Man (IM postcodes): charge UK VAT as you would for Leeds or Cardiff. The island has its own VAT office, but Manx VAT law broadly follows UK law and the two form a customs union.
• Jersey (JE postcodes): a zero-rated export from the UK, with Jersey's own 5% Goods and Services Tax (GST) on most goods.
• Guernsey, Alderney, Sark and Herm (GY postcodes): a zero-rated export from the UK, with no VAT or GST on arrival.

Northern Ireland is the exception: supplies from Northern Ireland to the Isle of Man follow different rules, so brands shipping from a Belfast warehouse should check separately.

Isle of Man Orders: Domestic for VAT, Not Always for Carriers

An Isle of Man order is a UK order for VAT, so it needs no export evidence and no zero-rating. The practical risk sits with carriers, not tax.

Some courier services do not cover the island, some route it differently or charge more, and transit times are longer than the mainland because every parcel has to cross by sea or air. Before you offer Isle of Man delivery, check which of your services cover IM postcodes and what delivery promise you can honestly make at checkout. At Fulfil with Synergy, our courier management service integrates with carriers including DHL, DPD, Royal Mail and UPS, so an island order can go on the service that actually reaches it rather than the default mainland one.

Check your checkout too. If your platform's UK shipping zone excludes IM postcodes, or lumps them in with international rates, Manx customers either cannot order or are overcharged.

Jersey Orders: Zero-Rated Exports With 5% GST

For UK VAT, a Jersey order is an export you can zero-rate if you hold evidence. For the customer, it may carry 5% Jersey GST, and who collects it depends on whether you are registered in Jersey.

If you are not registered for Jersey GST: goods for personal use worth £60 or less arrive without GST. Above £60, GST is charged on the whole value, including packing and freight, not just the amount over the threshold. Items arriving together in one shipment are treated as a single delivery. The customer is asked to declare and pay GST online, and the carrier only releases the parcel once it has been paid. Splitting an order to stay under £60 does not work; the relief is withdrawn where goods are artificially split.

If you are registered for Jersey GST: you charge 5% at checkout and the parcel arrives with nothing to pay. Revenue Jersey's guidance for overseas retailers says registration is mandatory once your sales to Jersey consumers exceed, or are likely to exceed, £300,000 in a rolling 12 months. Below that, you can register voluntarily. Registered sellers file quarterly returns online, and when a customer returns goods, the seller refunds the GST as part of the refund.

Most UK-made or UK-cleared goods move to Jersey without customs duty, because Jersey is in a customs union with the UK. The guidance notes that non-UK goods worth more than £135 need a customs declaration and may attract duty, although many goods carry a 0% rate. If you sell imported products at higher price points, ask a broker how your lines are treated.

Guernsey, Alderney and Sark: No GST, but Still an Export

Guernsey charges no VAT or GST, so customers there pay no sales tax on arrival. For your UK VAT return the order is still an export, and you need the same evidence and customs data as for Jersey.

The States of Guernsey's import declaration guidance says declarations are needed for goods coming directly from countries other than the UK, Jersey or the Isle of Man. Excise goods are the exception: they need an import declaration regardless of where they come from. That covers alcohol and tobacco, and vaping liquids join the list from 9 November 2026. If you sell any of these, island orders need extra handling before you switch them on.

Alderney and Sark share GY postcodes with Guernsey, so check that your checkout and carrier both recognise them and do not reject them as unknown UK addresses.

The Paperwork That Travels With Each Channel Islands Parcel

Every parcel to Jersey or Guernsey needs a complete customs declaration, with the island, not the UK, as the destination country. HMRC's Notice 703 says every parcel needs its own fully completed declaration because customs may inspect each one, and the description must cover every item with quantity, weight and value.

The same Notice sets the VAT side. To zero-rate, the goods must leave the UK and you must hold valid evidence of export within three months of the sale. For postal exports, that means a certificate of posting or a carrier manifest; for couriers, the invoice with its air waybill numbers. Excise goods and goods under customs control always need an electronic export declaration through the Customs Declaration Service.

In practice, the declaration is only as good as your product data. Vague descriptions, missing country of origin and values that do not match the invoice are what get parcels held. Our guide to EORI numbers, Incoterms and customs paperwork covers what a good declaration contains.

Three Ways to Serve Island Customers

You can exclude the islands, include them with clear messaging, or collect Jersey GST at checkout. The right choice depends on how many island orders you get and what they are worth.

1. Exclude the islands. Simple, but you lose customers who already want to buy and who often have few local alternatives. Run the numbers on current island traffic before you choose this.
2. Include them with honest messaging. Show longer delivery times at checkout, explain that Jersey orders over £60 may attract 5% GST payable before delivery, and zero-rate the UK VAT on Channel Islands orders so the price reflects it. This needs no registration, but some Jersey customers will still meet a payment request.
3. Register for Jersey GST and charge it upfront. The customer pays once, at checkout, and the parcel is not held for payment. This gives the best experience and becomes compulsory above £300,000 a year, but it adds quarterly returns and needs reliable product and order data.

Whichever route you take, island orders should be identified as soon as they drop, not discovered at the packing bench. The wider guide to cross-border ecommerce fulfilment covers how the same logic applies to the EU and further afield.

What to Ask a 3PL Before You Switch Island Delivery On

A fulfilment partner should be able to answer these questions in plain terms before the first island order ships.

• Which carrier services reach Jersey, Guernsey, Alderney, Sark and the Isle of Man, and what are the transit times?
• How are JE, GY and IM orders flagged so they are not packed and labelled as mainland parcels?
• Where does the customs description, value and country of origin for each SKU come from, and who checks it?
• How is evidence of export captured and kept for your VAT records?
• What happens when a parcel is held or refused, and how quickly will you hear about it?
• How are returns from the islands received, inspected and refunded?

Most held parcels trace back to a handful of avoidable data errors. Our article on how documentation errors delay cross-border orders sets out the common ones.

How Fulfil with Synergy Handles Island Orders From Northampton

Fulfil with Synergy is a founder-led UK third-party logistics (3PL) provider that runs multi-channel, retail and Amazon Seller Fulfilled Prime fulfilment for growing and household brands from purpose-built facilities in Northampton. It combines AutoStore automation and the RedPrairie Dispatcher warehouse management system with high-touch services such as kitting, bonded warehousing and returns management.

For island orders, three parts of that set-up matter most:

• Data held at the right level. RedPrairie Dispatcher gives real-time inventory visibility down to unit, SKU, batch and location, with a time-stamped audit trail of every stock movement and exception handling that flags issues before they become delays.
• Carrier choice and address checks. Courier management covers domestic and cross-border services, address validation software checks delivery data against Royal Mail and other sources, and exceptions are handled proactively when a parcel does not go to plan.
• Returns that close the loop. Every return is scanned, inspected, reason-coded and photographed, and processed within 48 hours of arriving, so island customers are not waiting even longer for a refund.

Where a brand needs specialist tax help, such as registrations and customs set-ups, the Fulfil Plus partner network includes global trading and compliance specialists. Our team of over 280 fulfilment specialists works seven days a week, and dedicated account management means island orders are flagged, labelled and reported the way you agree up front.

A Six-Step Launch Checklist

1. Pull 12 months of orders and abandoned checkouts with JE, GY and IM postcodes to size the opportunity.
2. Confirm which carrier services reach each island and set realistic delivery promises.
3. Decide your Jersey approach: unregistered with clear messaging, or registered and collecting GST at checkout.
4. Set up checkout zones so the Isle of Man is charged UK VAT and Channel Islands orders are zero-rated.
5. Complete customs descriptions, values and country of origin for every SKU you will ship.
6. Send test orders to each island, then check delivery times, any charges the customer paid and your export evidence.

FAQ

Do I need to register for GST in Jersey?

Only if your sales to Jersey consumers exceed, or are likely to exceed, £300,000 in a rolling 12 months. At that point registration with Revenue Jersey is mandatory and you charge 5% GST at the point of sale. Below the threshold you can register voluntarily, which lets your Jersey customers pay once at checkout instead of meeting a payment request on arrival. Registered sellers file quarterly returns online and refund GST to customers who return goods. If you are unsure whether registering is worth it, compare your Jersey order volumes against the admin of quarterly returns with your accountant.

Does the EU's €150 parcel change affect orders to the islands?

No, not directly. The EU began charging customs duty on low-value parcels worth up to €150 from 1 July 2026, but Jersey, Guernsey and the Isle of Man are all outside the EU, and officials quoted by ITV News did not expect the change to affect UK shipments to Jersey. The knock-on risk is operational: Jersey Customs has pointed to carriers wrongly treating the island as an international destination, and a parcel processed as international can be delayed or held for paperwork it does not need. Check how your carrier classifies each island, and keep EU and island orders on separate rules in your checkout and warehouse.

How should I handle returns from Jersey and Guernsey?

Make the process clear before the customer buys, because returns from the islands cost more and take longer to arrive than mainland returns. Give customers a clear returns address, the service to use and who pays for it. If you are registered for Jersey GST, refund the GST as part of the refund, so the customer does not have to claim it back. Once a return reaches the warehouse, speed matters: at Fulfil with Synergy every return is processed within 48 hours of arriving, so the refund is not held up a second time. Track island return reasons separately to spot transit damage.

Do parcels to the Isle of Man need a customs declaration?

Generally no. The Isle of Man and the UK form a customs union and a common VAT area, so goods sent from Great Britain to the island are treated as domestic supplies rather than exports. In practice, you ship an Isle of Man order much like a mainland order, with UK VAT on the invoice. The checks that matter are carrier coverage, transit times and any extra delivery charges for the crossing. Shipping from Northern Ireland follows different rules, so check those separately. Restricted goods, such as alcohol, may still face carrier limits, so confirm with your carrier before listing them.

Can I ship alcohol or vapes to Guernsey?

You can, but excise goods need extra paperwork. Guernsey requires an import declaration for excise goods regardless of where they come from, so alcohol and tobacco cannot travel as ordinary parcels, and vaping liquids join that list from 9 November 2026. On the UK side, HMRC requires an electronic export declaration for excise goods sent to the Channel Islands. Carriers also set their own restrictions on alcohol and e-liquids. If these products make up part of your range, agree the process with your fulfilment partner and a customs broker before you switch island delivery on.

Island customers want the same thing as anyone else: a clear price, a realistic delivery date and no surprise at the door. If you want to offer delivery to Jersey, Guernsey and the Isle of Man with clean customs data and fewer held parcels, talk to Fulfil with Synergy about your products, carriers and checkout set-up.
