Importing from China to Jersey and the Channel Islands
The Channel Islands are in a customs union with the UK but outside the UK VAT area. UK duty rates apply, GST at 5 per cent replaces import VAT, and below the registration threshold you cannot reclaim it.

The short answer
Jersey, Guernsey and the Isle of Man are in a customs union with the United Kingdom, but they sit outside the UK VAT area. That one sentence explains almost every difference you will meet.
Because of the customs union, the duty rate on goods arriving from China is the rate in the UK Trade Tariff, and the commodity code you would look up for a Great Britain import is the code that applies. Anti-dumping duty applies the same way. Moving goods between the islands and the UK does not attract import duty in either direction.
Because the islands are outside the UK VAT area, there is no UK import VAT on a consignment cleared in Jersey. Jersey charges GST instead, at 5 per cent. That is a lower headline rate than 20 per cent, and for a small importer it is often a worse deal, for a reason covered below.
Duty: the same tariff, a different customs service
The customs union means Jersey applies the UK Customs Tariff to trade with territories outside it, which includes China. So the research you would do for a Great Britain import is not wasted: find the commodity code, read the third-country duty rate, and check whether any anti-dumping or countervailing measure covers Chinese goods under that code.
What changes is who you deal with and where. The declaration is made to Jersey Customs and Immigration through their CAESAR system rather than to HMRC through CDS, and a customs declaration is required for imports valued above 135 pounds.
The practical consequence is that a Great Britain customs broker is not automatically the right broker. Ask whoever you are considering whether they file in CAESAR themselves or hand off to an island agent, because a handoff is a place where information gets lost and days get added.
GST instead of VAT, and the threshold that decides whether it hurts
GST is charged at 5 per cent, and it applies to goods imported by a business. The 60 pound easement that lets small consignments through without GST is for goods imported by a person for personal use from an unregistered retailer; it is not available for business imports, so as an importer you should plan on paying GST on everything.
Whether that 5 per cent is a cost or a cash flow item depends entirely on registration. GST registration is mandatory above 300,000 pounds of turnover, and a registered business can reclaim the GST it has paid on business purchases and imports. Below the threshold you are not registered, you cannot reclaim, and the 5 per cent is simply part of what the goods cost you.
This is the point most people get backwards. A Great Britain importer pays 20 per cent import VAT and, if VAT registered, gets all of it back, so the true cost is nil and the issue is timing. A small Jersey importer pays 5 per cent and keeps none of it, so the true cost is 5 per cent of the customs value on every single shipment. It belongs in your landed price from the first order, not discovered at the end of year one.
Registering voluntarily below the threshold is a decision worth taking advice on rather than guessing at, because it also means charging GST on what you sell.
The route, and the question to ask your forwarder
Very little sails from China to the Channel Islands directly. In practice a container arrives at a Great Britain port and the goods make a second, short leg by sea to the island, which adds a handling point, a cost and usually a few days.
Routing through a Great Britain port is normal and perfectly workable. The tax question is not whether the goods touch Great Britain, it is whether they are cleared there.
Goods landed at a Great Britain port sit in temporary storage until they are assigned a customs-approved treatment. Entry to free circulation is one such treatment, and it is the one that makes UK import VAT due. If instead the goods stay uncleared and move on to the island to be declared in Jersey, no UK import VAT arises, because they were never released into the UK market. Common Transit paperwork is not needed for the island leg, since the Channel Islands are inside the customs union with the United Kingdom.
Get that wrong and it is expensive rather than merely annoying. A Jersey business with no UK VAT registration has no mechanism to recover UK import VAT, so 20 per cent of the customs value would sit permanently in your cost base, on top of the Jersey GST you still pay on arrival.
So put the question to your forwarder in writing before you book, and get the answer in writing: where will these goods be declared, and will they remain uncleared through Great Britain so that the declaration is made in Jersey. A forwarder who quotes a good rate but cannot answer that clearly is quoting on a shipment they have not thought through.
The same logic applies to a supplier offering DDP. A DDP price quoted by a Chinese supplier for a Great Britain address, with the island leg bolted on afterwards, is exactly the arrangement that produces an unrecoverable VAT charge.
Product safety: UKCA does not apply, but your duties do
UKCA marking does not apply in the Crown Dependencies. Jersey has its own framework under the Consumer Safety (Jersey) Law 2006, and if you import consumer goods into the island you are a producer under it.
Being a producer carries real duties. You must supply a safe product. You must provide warnings and instructions clear and durable enough that a consumer can understand the risks in using it and take precautions against them. You must mark products, or batches, so they can be identified and traced. You are expected to sample test, investigate complaints and pass risk information down the chain, and to contact the Chief Consumer Safety Inspector immediately if you find a product is unsafe.
Two mistakes follow from misreading this. The first is assuming that because UKCA does not apply there is nothing to do; the general safety duty is not a formality, and traceability marking is a positive obligation you have to build into the order. The second is assuming a mark on the product is the evidence; it is the test reports and technical documentation behind the mark that show the product was actually assessed, and those are what you should be asking the factory to hand over.
If you also intend to sell into Great Britain, then the Great Britain rules apply to those goods on their own terms, and you should specify to the higher of the two requirements rather than manufacture twice.
What it means for your first order
Build the landed price with the 5 per cent GST in it as a cost rather than a recoverable item, unless you are registered. Add the island leg and the second handling as a real line, not a rounding.
Order quantities are usually smaller than a mainland equivalent, which matters more than the tax does. A small first order sits badly against factory minimums, so expect to pay a premium per unit, and expect tooling costs to be spread across fewer units. That is normal for a first order anywhere and it is sharper here.
Decide where the goods will be declared before you agree an incoterm, not after. The incoterm and the clearance plan are the same decision, and on this route getting them the wrong way round is the expensive mistake.
Frequently asked questions
Do I pay UK import duty on goods from China to Jersey?
You pay duty at the UK Trade Tariff rate, but to Jersey rather than to HMRC. Jersey is in a customs union with the United Kingdom and applies the UK Customs Tariff to trade with territories outside the union, so the commodity code and third-country duty rate you would use for a Great Britain import are the ones that apply, anti-dumping measures included.
Is there VAT on imports into Jersey?
No. Jersey is outside the UK VAT area, so there is no UK import VAT on goods cleared in Jersey. GST applies instead at 5 per cent, and it applies to business imports without the 60 pound easement that covers personal imports.
Can I reclaim the GST I pay on imports into Jersey?
Only if you are GST registered. Registration is mandatory above 300,000 pounds of turnover, and a registered business can reclaim GST paid on business purchases and imports. Below that threshold you are not registered and cannot reclaim, so the 5 per cent is a genuine cost that has to sit in your landed price.
Does UKCA marking apply in Jersey?
No. UKCA does not apply in the Crown Dependencies. Jersey regulates product safety under the Consumer Safety (Jersey) Law 2006, which makes anyone importing consumer goods into the island a producer, with duties to supply a safe product, provide adequate warnings and instructions, and mark goods so they can be traced.
Can goods ship from China to Jersey directly?
Rarely, and routing via a Great Britain port is the normal way to do it. The consignment lands at a GB port and travels on by a second short sea leg, adding handling, cost and a few days. What matters is that the goods are not entered to free circulation in Great Britain: if they stay uncleared and are declared in Jersey, no UK import VAT arises, and no Common Transit paperwork is needed for the island leg because the islands are inside the customs union.
Is Guernsey the same as Jersey for this?
For customs, broadly yes: Guernsey and the Isle of Man are in the same customs union with the United Kingdom, and movements between the islands and the UK are free of import duty. For tax they are not the same, because each island sets its own rules, so confirm the local position rather than assuming Jersey GST applies elsewhere.
