Importing Electronics from China to the UK: Post-Brexit Guide

The UK customs system changed dramatically in January 2021 when Brexit took full effect. If you’ve been importing into the EU and assume the UK works the same way, you’ll find several surprises. And if this is your first time importing electronics anywhere, the UK is honestly a reasonable place to start, because the process is well-documented and customs agents are good.

But there’s one compliance issue that catches almost everyone sourcing electronics from China for the UK market: UKCA marking. It’s not complicated, but the timeline for getting it done is longer than most first-timers expect.

UK Customs After Brexit

Before 2021, the UK was part of the EU customs union. Goods moved freely across the border. CE marking covered both markets. That’s over.

Great Britain (England, Scotland, and Wales) now operates a fully independent customs regime. The UK Global Tariff replaced the EU’s Common Customs Tariff for GB. The Customs Declaration Service (CDS) replaced CHIEF as the electronic filing system. And UKCA marking replaced CE marking for product compliance in Great Britain.

Northern Ireland is different, and that difference is the source of ongoing headaches for importers. More on that below.

UKCA Marking: The Most Important Thing to Get Right

The UK Conformity Assessed (UKCA) mark is the UK equivalent of the CE mark. For most consumer electronics, you need UKCA marking to legally sell in Great Britain.

The requirements mirror CE marking in most respects: you need a technical file, a Declaration of Conformity (DoC), and testing against the relevant UK designated standards. The standards themselves are largely identical to the EU harmonised standards (UK adopted them wholesale post-Brexit).

The key difference is the Authorised Representative. For CE marking, you need an EU-based Responsible Person if you’re a non-EU manufacturer or importer. For UKCA, you need a UK-based Responsible Person.

If your Chinese supplier handles CE certification (as many larger factories do), that CE documentation doesn’t automatically give you UKCA. The testing may transfer, but you need a UK RP and UK Declaration of Conformity.

What “UKCA mark” covers for electronics:

Radio Equipment: The UK Radio Equipment Regulations 2017 govern anything with WiFi, Bluetooth, or other intentional radio transmission. This covers the majority of consumer electronics.

Electrical Safety: The Electrical Equipment (Safety) Regulations 2016 cover general electrical safety for powered devices.

EMC: The Electromagnetic Compatibility Regulations 2016 cover electromagnetic interference and immunity.

For products that were CE-certified before Brexit, there was a transition period allowing CE marks in Great Britain. That transition has ended. For most product categories, UKCA is now required. Check the current status at gov.uk/ukca, because the government has extended deadlines multiple times and the rules for specific categories continue to evolve.

One important practical point: for low-risk product categories where there’s no requirement for third-party testing under CE, UKCA is also self-certifiable. Your Chinese supplier can provide the test reports, you review them, and you issue the UK DoC under your name as the importer or brand owner. For products requiring notified body involvement under CE (certain radio equipment, active implantable medical devices), you’ll need a UK Approved Body for UKCA.

Northern Ireland: The Exception That Matters

Northern Ireland is not Great Britain. Under the Windsor Framework, Northern Ireland maintains regulatory alignment with the EU for goods. CE marking is still accepted in Northern Ireland. UKCA is also accepted.

If you’re selling across the whole UK including Northern Ireland, CE marking gets you into Northern Ireland but not into England, Scotland, or Wales. UKCA gets you into Great Britain but not into the EU. A product sold UK-wide needs both marks in practice, or UKCA alone if Northern Ireland accepts it (which it does for most product categories).

For most small importers, this is a background issue. If you’re selling consumer electronics through UK e-commerce and the odd order ships to Belfast, having UKCA is sufficient. But if you’re selling significant volume into Northern Ireland specifically, understand which mark applies to which part of the UK.

UK Global Tariff Rates for Electronics

The UK’s global tariff (the MFN rate applied to goods from countries without a trade agreement) for electronics is generally low. Most consumer electronics attract 0-3.7%.

Common rates:

Smartphones and cell phones (UK commodity code 8517 12 00 10): 0% customs duty.

Headphones and earphones (8518 30 95 00): 0-3.7% depending on exact classification.

Power supplies and chargers (8504 40 55 00): 2.4%.

Laptop computers (8471 30 00 00): 0%.

Portable Bluetooth speakers (8518 22 00 00): 0%.

These are MFN rates. The UK doesn’t have a free trade agreement with China. So you’re paying MFN rates on all China-origin goods.

These rates are generally lower than you might expect. The UK Global Tariff inherited most of the EU CCT structure and the UK government has been reluctant to raise tariffs on consumer goods that UK consumers buy in volume.

But don’t let the low duty rates mislead you about your total landed cost. VAT is the big number.

UK VAT on Imports

The UK standard VAT rate is 20%. Most electronics attract the standard rate (reduced rates for children’s products and certain basic goods don’t apply to electronics).

When you import goods into the UK for business purposes, you pay import VAT at the point of entry. For formal entries through CDS, you can defer import VAT payment using a duty deferment account. You set up a DDA with HMRC, provide a guarantee (or get HMRC approval based on your financial standing), and pay the VAT monthly rather than per shipment. This improves cash flow for importers moving volume.

Without a deferment account, you pay import VAT to your customs agent before your goods clear customs. That’s a real cash flow issue on large shipments. A 20% VAT hit on a $50,000 shipment is $10,000 that ties up working capital until you reclaim it on your VAT return.

If you’re VAT registered in the UK (required once your turnover exceeds £90,000 per year, optional below that), you reclaim import VAT through your periodic VAT return. The VAT is tax-neutral for VAT-registered businesses in the end, but the timing of payment and reclaim matters for cash flow planning.

If you’re selling directly to UK consumers (B2C) rather than through a UK distributor, you may also need to charge VAT on your sales. Non-UK businesses selling goods to UK consumers must register for UK VAT if they exceed the registration threshold or hold goods in a UK warehouse (including through Amazon FBA UK). This is separate from import VAT and has its own set of rules.

Commodity Codes: The UK 10-Digit System

The UK uses commodity codes for customs declaration. They’re 10 digits: the first 6 match the international HS code (same as the US HTS first 6 digits), but the last 4 digits differ from both EU and US extensions.

You can look up UK commodity codes at trade-tariff.service.gov.uk. This tool also shows the import duty rate, VAT treatment, and any import controls or licenses required for each code.

The reason this matters: the UK has diverged somewhat from EU CN codes (the EU’s 8-digit extension of HS). If you’ve been importing into the EU and have EU CN codes, you can’t assume the full 10-digit code maps directly. Use the UK tariff tool for each product category.

Your customs agent will handle this in practice, but knowing your commodity code before you start lets you calculate duty costs accurately when you’re deciding whether a product makes commercial sense to import.

CDS: The Customs Declaration Service

CHIEF was the UK’s legacy customs system. CDS (Customs Declaration Service) replaced it. All UK customs entries now go through CDS.

You don’t file in CDS directly unless you’re a customs agent or have direct trader access. Most importers use a UK customs broker (called a customs agent) who has CDS access and files on your behalf.

CDS declarations are more data-rich than CHIEF entries. More fields are required. This is actually good for you in one sense: it forces precision in documentation, which reduces the ambiguity that triggers customs queries.

For your customs agent, they’ll need: commercial invoice, packing list, bill of lading or airway bill, UKCA declaration of conformity (for products that require it), and an EORI number for both you and your agent.

EORI Number: Get This First

An Economic Operators Registration and Identification (EORI) number is required to import into the UK. You can’t file a customs declaration without one.

UK EORI numbers start with “GB”. If you have an EU EORI (starts with your country code, e.g., DE for Germany), it doesn’t work for UK customs. These are separate systems.

Get your UK EORI number from HMRC at gov.uk. It’s free, and most businesses receive it within a few working days. You need a UTR (Unique Taxpayer Reference) or VAT number to apply as a UK-registered business. If you’re a non-UK business importing into the UK, there’s a process for that too, but you may need to appoint a customs agent with direct representation to act as the importer of record.

Using a UK Customs Agent

For most small-to-mid electronics importers, a customs agent (broker) is not optional. It’s the practical reality.

A good UK customs agent will handle CDS filing, ISF-equivalent pre-arrival notifications, duty and VAT calculations, and communication with HMRC Border Force if your goods are selected for examination.

UK customs agent fees are typically £100-300 per entry for straightforward shipments. For FCL (full container load) shipments with complex commodity splits, expect higher fees. Ongoing relationships with an agent who knows your products reduce errors and time.

When selecting an agent, look for experience with electronics from China specifically. Ask whether they’re familiar with UKCA compliance documentation requirements. An agent who handles fashion and food imports primarily may not know the nuances of radio equipment declarations.

WEEE Registration for Direct-to-Consumer Importers

If you’re importing electronics and selling directly to UK consumers (not through a UK distributor who takes title to the goods), you’re a producer under the Waste Electrical and Electronic Equipment (WEEE) regulations.

Producers must join a WEEE compliance scheme and fund the collection and recycling of end-of-life electronics. The cost depends on the weight of products you place on the UK market. It’s typically not huge for small importers, but it’s a legal requirement.

If you’re selling through a UK-registered distributor or retailer who buys your goods at import, they become the producer and handle WEEE obligations. Many small China importers work through UK distributors specifically to avoid this and UKCA obligation complexity, though that obviously reduces margin.

Approved Test Labs for UKCA

If your product requires testing (most radio equipment does), you need test reports from a competent laboratory. For UKCA, you don’t necessarily need a UK-based lab. Labs accredited by UKAS (UK Accreditation Service) or by accreditation bodies with mutual recognition agreements with UKAS are acceptable.

In practice, most large Chinese test labs (SGS, Intertek, Bureau Veritas, TUV SUD with China branches, and Chinese-owned labs like CNAS-accredited ones) can produce test reports that support UKCA declarations, as long as the tests are conducted against the UK designated standards.

Your Chinese factory will often offer to arrange CE testing through their local contacts. Ask whether those reports also cover UK designated standards. In most cases they do, since the standards are identical. But confirm before paying for separate UK testing, and confirm that the lab’s accreditation is acceptable for UKCA purposes.

Practical Timeline for UK Imports

Production lead time from China: same as US imports. 15-90 days depending on whether goods are in stock or custom production.

Ocean freight transit to UK ports (Felixstowe is the primary container port for China imports, Southampton and London Gateway are alternatives): 25-35 days from major China ports. The route typically goes through Suez Canal, making it longer than transpacific.

Air freight from China to London Heathrow or other UK gateways: 5-7 days.

UK customs clearance: 1-3 days for standard CDS release. Longer if selected for examination by Border Force.

Inland delivery from Felixstowe or other entry ports to your warehouse: 1-2 days.

Total realistic timeline for sea freight: 6-9 weeks from production completion to warehouse. Air freight cuts this to about 2-3 weeks from production completion.

For a first import, add buffer. Your UKCA paperwork needs to be ready before the goods arrive at port, not after.

Frequently Asked Questions

Do I need UKCA marking before my goods ship from China? Yes, in the sense that the documentation must be in order before you import and sell. You don’t physically mark the goods at customs, but if your goods arrive and your UKCA Declaration of Conformity isn’t ready, you’ve imported goods you can’t legally sell. Have the DoC done before you place the production order.

Can I still use CE marking for UK sales? For Great Britain, CE marking is no longer sufficient for most product categories. UKCA is required. CE is still valid in Northern Ireland. If you only sell in the EU and Northern Ireland, CE alone may be sufficient for your situation.

What’s the difference between a customs agent and a freight forwarder? A freight forwarder arranges the physical movement of your goods (booking containers, managing sea or air logistics). A customs agent files customs declarations. Many companies do both, and most importers use a freight forwarder that also offers customs clearance services. Confirm both capabilities before signing up.

Is there a de minimis threshold in the UK like the US $800 rule? The UK has a £135 customs duty threshold. Goods valued under £135 can enter the UK with no customs duty (but VAT still applies). This is lower than the US threshold and applies differently for B2B vs B2C sales. For commercial B2B shipments from China, this threshold is irrelevant for most orders.

How long does it take to get a UK EORI number? Typically 3-5 working days from HMRC once you’ve applied online. Apply well before your first shipment is due to arrive. You can’t clear customs without it.

What happens if I sell electronics in the UK without UKCA marking? Trading Standards can order a product withdrawal, issue fines, and in serious cases pursue criminal prosecution. Non-compliant products sold through UK online marketplaces can have their listings removed by the platform. The risk is real, and it falls on you as the importer and brand owner.
