Right, let's cut through the confusion. UK customs, import duty, and VAT on imported goods is the one area where most UK business owners admit they're winging it — and that's completely understandable. Post-Brexit rules, a new Customs Declaration Service, UKVFTA preferential rates, postponed VAT accounting — it's a lot. But getting it wrong costs real money: penalties from HMRC, goods held at Felixstowe, unexpected duty bills that wipe out your margin, or overpaying duty when you didn't need to.
At Epic Sourcing, we've helped hundreds of UK businesses navigate the import process — from first-time Amazon sellers ordering 500 units from Shenzhen, to established brands importing containers weekly from Vietnam. This guide covers everything you need to know about UK customs duty and import VAT in 2026: how it works, how to calculate it, where the real traps are, and where the genuine savings are hiding.
UK-based business owners, founders, and buyers who source or plan to source products from China, Vietnam, or elsewhere in Asia — whether you're placing your first order or managing a supply chain of 12+ SKUs. If you've ever Googled "how much will customs cost?" and got a different answer every time, this guide is for you.
UK import duty (also called customs duty) is a tax applied by HMRC when goods enter Great Britain from outside the UK, calculated as a percentage of the customs value of your goods based on their commodity code in the UK Global Tariff. Import VAT is a separate 20% charge applied on top of the goods value plus duty, though most VAT-registered UK businesses can reclaim it — provided they use Postponed VAT Accounting (PVA).
Since Brexit took full effect on 1 January 2021, UK importers have been operating under a completely separate customs and tariff framework from the EU. The UK Global Tariff (UKGT) replaced the EU Common External Tariff and, whilst many rates were initially kept the same, the UK has been progressively diverging — with targeted changes to tariff codes, new suspension regimes, and preferential trade agreements striking out in their own direction. If you're still using pre-2021 customs knowledge, you may well be working with outdated assumptions about the duty rates that apply to your goods.
In 2026, there are three big reasons customs has moved up the agenda for UK importers. First, HMRC has significantly expanded its customs compliance activity — post-clearance audits, Customs Civil Evasion Penalty notices, and demand for better record-keeping have all increased. Second, import costs have become a genuine competitive differentiator: businesses that understand their commodity codes, claim preferential duty rates under UKVFTA or the UK's Generalised Scheme of Preferences (UKGSP), and use Postponed VAT Accounting correctly are operating with meaningfully better cash flow than those who don't. Third, the cost of getting it wrong has risen — both in terms of HMRC penalties and the reputational risk of goods being detained at port.
The good news: once you understand the framework, customs isn't as complicated as it seems. It's a system built on three core questions — what are you importing, where is it from, and what is it worth? Get those three answers right, and you'll pay the correct duty, reclaim your import VAT efficiently, and sail through clearance.
UK-China imports were approximately £71bn in the year to March 2025, making China the UK's largest single source of goods imports. UK-Vietnam trade reached approximately £9.6bn in 2024. Together, these two markets supply the majority of manufactured goods sourced by UK businesses — making correct customs classification and duty management essential, not optional.
Every product imported into the UK is assigned a commodity code — a 10-digit number based on the international Harmonised System (HS) that classifies goods globally. In the UK, these codes sit within the UK Trade Tariff, administered by HMRC. The commodity code determines three critical things: the standard (MFN) duty rate, any preferential rates available under trade agreements, and whether any import controls, licensing, or anti-dumping duties apply.
The UK applies the Most Favoured Nation (MFN) rate by default — this is the standard rate applied to goods from countries with which the UK has no preferential trade agreement. China does not have a free trade agreement with the UK, so virtually all goods imported from China attract the full MFN rate. MFN rates vary enormously by product: clothing typically attracts 12%, footwear can be 0–17%, electronics are often 0–3.5%, furniture ranges from 0–5.6%, and toys sit at 0–4.7%. The only way to know your exact rate is to find your commodity code.
You can look up commodity codes using HMRC's Trade Tariff tool at trade-tariff.service.gov.uk. Be warned: classification is not always obvious, and misclassification is one of the most common — and costly — customs errors. A yoga mat might be classified as sporting goods, rubber goods, or foam products depending on its composition, each with a different duty rate. If you're in any doubt, HMRC offers a Binding Tariff Information (BTI) service that gives you a legally binding classification, valid for three years.
| Product Category | Typical UK MFN Duty Rate | Notes |
|---|---|---|
| Clothing & apparel | 10–12% | Varies by fibre content and construction |
| Footwear | 0–17% | Leather uppers attract higher rates |
| Consumer electronics | 0–3.5% | IT Agreement covers many tech products at 0% |
| Furniture | 0–5.6% | Wooden furniture typically 0–2.7% |
| Gym & fitness equipment | 0–4.7% | Most equipment 0% under ITA |
| Toys & games | 0–4.7% | Board games 0%, some plastic toys 4.7% |
| Health & beauty products | 0–6.5% | Cosmetics typically 0–2%, supplements vary |
| Homeware & kitchenware | 0–6.7% | Ceramic goods can attract higher rates |
Some product categories from China attract additional anti-dumping or countervailing duties on top of the standard MFN rate. Products historically affected include certain steel products, solar panels, ceramic tiles, and e-bikes. Always check the full tariff schedule for your commodity code — the headline duty rate is sometimes only part of the story.
This is where most UK importers need clarity. The calculation follows a specific sequence — and getting the order right matters. Here's exactly how it works.
The customs value is the basis on which duty is calculated. For most commercial imports, UK customs uses the transaction value method — essentially, what you actually paid for the goods. This is the CIF (Cost, Insurance, Freight) value, meaning the price of the goods plus the cost of shipping and insurance to bring them to the UK border. If your supplier quotes FOB (Free on Board), you need to add the sea or air freight cost and insurance to arrive at the CIF customs value.
Example: You order 1,000 units of a product from a factory in Guangzhou. The factory FOB price is £8,000. Sea freight to Felixstowe costs £1,200. Marine insurance is £80. Your CIF customs value is therefore £9,280.
Apply the duty rate for your commodity code to the CIF customs value.
Example continued: Your product is a textile item attracting 12% MFN duty. Duty = £9,280 × 12% = £1,113.60.
Import VAT is charged at 20% on the VAT value, which equals the customs value plus import duty plus any other customs charges. It is not just VAT on the goods price.
Example continued: VAT value = £9,280 + £1,113.60 = £10,393.60. Import VAT = £10,393.60 × 20% = £2,078.72.
Total landed tax bill in this example: £1,113.60 duty + £2,078.72 VAT = £3,192.32. If you're VAT-registered and using Postponed VAT Accounting (covered in Section 6), you don't pay the £2,078.72 in cash — you simply account for it on your VAT return and reclaim it in the same period.
| FOB goods value | £8,000 |
| + Freight & insurance | £1,280 |
| = CIF Customs Value | £9,280 |
| Import Duty (12%) | £1,113.60 |
| = VAT Value | £10,393.60 |
| Import VAT (20%) | £2,078.72 |
| Total Duty + VAT | £3,192.32 |
An EORI (Economic Operators Registration and Identification) number is your unique identifier for customs declarations in the UK. Every business that imports or exports commercially in the UK must have one — you cannot clear goods through UK customs without it. If you're bringing in goods for your business, you need a UK EORI number, which takes the format GB followed by your VAT registration number followed by 000 (e.g. GB123456789000).
Apply through HMRC's online service — it's free and typically takes around a week, though it can be quicker. If you're VAT-registered, your EORI is linked to your VAT number. If you're not VAT-registered (for example, you're a startup below the £90,000 VAT threshold), you can still get an EORI — it just won't contain a VAT number.
A frequent mistake we see at Epic Sourcing: UK businesses placing their first overseas order without an EORI, then scrambling to get one when the goods arrive at port. The freight forwarder or customs broker cannot clear your goods without it, and every day goods sit in a container at Felixstowe or Southampton accumulating demurrage charges. Apply for your EORI as soon as you know you're importing.
If your business is based in Northern Ireland or you're selling goods into Northern Ireland, the Windsor Framework means NI operates under different rules — goods moving between GB and NI under the green lane scheme, with specific requirements around the Northern Ireland Protocol. This guide focuses on Great Britain (England, Scotland, and Wales) importing rules. NI businesses should seek separate advice on the Windsor Framework.
HMRC fully migrated UK customs declarations to the Customs Declaration Service (CDS) — replacing the legacy CHIEF system — in November 2023. If you're using a freight forwarder or customs broker (which most importers do), they'll be operating on CDS on your behalf. However, as the importer of record, it's important you understand what CDS means for your obligations.
Under CDS, there are more data fields to complete on import declarations compared to the old CHIEF system. Your freight forwarder needs accurate information from you: the correct commodity code, a full and accurate description of the goods, the correct customs value, country of origin, and supplier details. If any of this is wrong or incomplete, your goods can be held for examination, or you may receive a post-clearance correction demand from HMRC.
Importantly, CDS also makes it easier for HMRC to cross-reference customs declaration data with VAT returns. This is one reason compliance reviews have become more targeted. If you're importing £200,000 of goods per year but your customs declarations show a different picture from your VAT returns, expect scrutiny.
If you import regularly, a Duty Deferment Account (DDA) through HMRC lets you consolidate all duty payments for a month into a single direct debit on the 15th of the following month, rather than paying duty on each individual shipment at the time of clearance. For high-volume importers, a DDA can significantly improve cash flow. You'll need a bank guarantee or HMRC-approved financial security to set one up. Your freight forwarder may offer to use their own DDA for your shipments, which is a common arrangement — ask your broker.
This is the section where many UK importers realise they've been leaving real money on the table. Import VAT — the 20% charged on your customs value plus duty — is reclaimable by VAT-registered UK businesses. But how you manage that reclaim makes a significant difference to your cash flow.
Without PVA, your freight forwarder pays the import VAT on your behalf at the port and passes the cost onto you. You then reclaim it on your next quarterly VAT return — which could mean you're out of pocket for up to 3 months. On large shipments this is a meaningful cash flow cost. On a £50,000 container of goods, the import VAT alone could be £10,000–£12,000 that's locked up for a quarter.
Postponed VAT Accounting was introduced in January 2021 and is available to any UK VAT-registered business. With PVA, you don't pay import VAT at the point of import — instead, you account for it on your VAT return as both an output tax and an input tax in the same period, netting to zero cash outflow. HMRC provides a monthly C79 certificate (or under CDS, you access a statement via your customs financial account) as evidence for your reclaim.
To use PVA, you or your freight forwarder must enter your EORI number and indicate on the customs declaration that you wish to use PVA. This should be a standing instruction to anyone submitting declarations on your behalf. The reality is: every VAT-registered UK importer should be using PVA — there is no downside, only a significant cash flow benefit.
| Scenario | Without PVA | With PVA |
|---|---|---|
| When is import VAT paid? | At port on arrival | Accounted for on VAT return |
| Cash outflow? | Yes — immediate | No cash outflow |
| When reclaimed? | Next VAT return (up to 3 months later) | Same VAT return period |
| Who should use it? | Very few scenarios justify this | All VAT-registered UK importers |
| Cash flow on £50k shipment | ~£10,000 tied up for up to 90 days | £0 cash outflow |
If you're using a freight forwarder or customs broker and you're not sure whether PVA is being applied to your imports, ask them directly. Request confirmation in writing that PVA is being used on all your import declarations. This is a simple, costless change that can immediately improve your cash flow — we've seen UK businesses realise they've been paying import VAT unnecessarily for years.
This is where genuine competitive advantage is hiding for UK importers — and most businesses are completely unaware of it. The UK-Vietnam Free Trade Agreement (UKVFTA) came into force on 1 January 2021, the same day as Brexit. It provides preferential (reduced or zero) duty rates on a wide range of Vietnamese-origin goods imported into the UK. As of 2026, approximately 65% of tariff lines are at zero duty, with 99.2% of tariffs eliminated by the end of the scheduled phase-down period.
To claim UKVFTA preferential rates, your goods must meet the Rules of Origin requirements — meaning they must be genuinely of Vietnamese origin, not simply transshipped through Vietnam from China. The key document is a EUR.1 movement certificate (or a supplier's declaration for smaller shipments below £4,700). Your Vietnamese supplier must provide this at the time of shipment; it cannot be backdated after the goods have arrived in the UK.
The rules of origin under UKVFTA typically require that the final substantial transformation of the goods takes place in Vietnam. For textile and apparel products, this generally means the fabric must also be cut and sewn in Vietnam (the "double transformation" rule), not just assembled from Chinese-origin fabric. For other product categories, a value-added threshold or specific processing requirement applies. Your supplier should be familiar with these requirements — if they're not, that's a red flag.
| Product Category | Standard MFN Rate (China) | UKVFTA Rate (Vietnam) 2026 | Saving on £50k shipment |
|---|---|---|---|
| Clothing & apparel | 12% | 0–9.6% (phased) | Up to £6,000 |
| Footwear | Up to 17% | 0–8% (phased) | Up to £4,500 |
| Furniture | 0–5.6% | 0% (most categories) | Up to £2,800 |
| Bags & leather goods | 3.7–4.2% | 0% | Up to £2,100 |
| Plastic products & homeware | 0–6.7% | 0% | Up to £3,350 |
For businesses currently sourcing from China and considering diversification into Vietnam, the UKVFTA duty saving is a compelling additional financial argument — on top of the supply chain resilience benefits. If your product category attracts 12% MFN duty from China and you can source the same product from a Vietnamese factory with a UKVFTA certificate of origin, you're potentially saving thousands of pounds per container.
Our team can review your current product mix, identify UKVFTA eligibility, and model your potential savings before you commit to any new supplier relationships.
Book a Free 30-Minute ChatAt Epic Sourcing, we've seen every customs mistake in the book — because our clients often come to us after something has gone wrong. Here are the ones that cost UK importers the most money, and how to avoid them.
Using the wrong commodity code is the single most common customs error. It can result in underpayment of duty (leaving you exposed to backdated demands plus interest and penalties from HMRC) or overpayment (meaning you've been leaving money on the table). If you're not confident about your commodity code, pay for a BTI ruling from HMRC — it's worth every penny.
This is where things go seriously wrong. Some suppliers offer to "split invoices" — showing a lower value on the customs invoice to reduce your duty bill. This is customs fraud. HMRC actively investigates undervaluation, and the consequences include civil penalties of up to 100% of the unpaid duty, seizure of goods, and in serious cases, criminal prosecution. The correct customs value is what you actually paid for the goods. Don't let a supplier pressure you into invoice splitting — it's their short-term gain at your significant long-term risk.
If a supplier or freight agent suggests declaring a lower value on your customs documents than what you actually paid, decline immediately. This is customs fraud under UK law, regardless of how commonly it may occur elsewhere. The importer of record (your business) bears full legal responsibility — not the supplier, not the agent.
As covered in Section 6, PVA is free, accessible to all VAT-registered UK importers, and provides immediate cash flow benefit. Not using it is simply leaving money tied up unnecessarily. We still encounter businesses that aren't using PVA — usually because no one told them about it, or their freight forwarder didn't proactively suggest it. Ask your broker today.
If you're sourcing from Vietnam and want to claim UKVFTA preferential rates, you need the EUR.1 certificate from your supplier before the goods leave Vietnam. Many businesses discover this only after the goods arrive at Southampton — at which point it's too late, and you pay full MFN duty. Build documentation requirements into your purchase order terms with Vietnamese suppliers.
Your freight forwarder or customs broker acts as your agent — but the legal responsibility for the accuracy of customs declarations rests with you as the importer of record. If incorrect information is submitted (even if it was the forwarder who made the error), HMRC can pursue you for the underpaid duty and any penalties. This doesn't mean you can't use agents — you absolutely should. But you need to provide them with accurate information and retain records of the data you gave them.
Customs duty and VAT are only part of the import picture. Many product categories require UK-specific compliance marking before they can legally be sold on the UK market. UKCA (UK Conformity Assessed) marking has replaced CE marking for most product categories in Great Britain. Products covered include electrical equipment, machinery, toys, PPE, medical devices, and many others. UK Border Force can detain non-compliant goods at the border. Your Chinese or Vietnamese supplier may have CE marking — but unless the product also has UKCA marking from a UK-approved body, it cannot be sold in Great Britain. This is a separate cost and process that many first-time importers overlook entirely.
Understanding customs, duty, and compliance rules is essential — but you don't need to become a customs expert yourself. At Epic Sourcing, we work alongside UK businesses as their sourcing partner throughout the entire process: from identifying and vetting suppliers in China and Vietnam, to managing quality control, logistics coordination, and making sure the documentation is correct from day one.
Our team on the ground in China has worked with hundreds of UK clients. We know which factories have experience with UKVFTA documentation for Vietnamese production, which commodity codes cause the most classification headaches, and how to structure your purchasing terms to protect you at the customs stage. Here's how our three service tiers support UK importers.

Consumer electronics are often 0%, clothing typically 10–12%, and footwear can reach up to 17%. The only reliable way to find your rate is to identify the correct 10-digit commodity code for your specific product using HMRC's UK Trade Tariff tool and look up the applicable rate. At Epic Sourcing, we routinely help clients calculate their expected duty exposure before placing their first order — so there are no surprises when the goods arrive at Felixstowe.
Yes — import VAT is technically charged when goods enter the UK, but if you're VAT-registered you can use Postponed VAT Accounting (PVA) so that no actual cash changes hands. With PVA, you account for import VAT on your VAT return as both an output tax and an input tax in the same period — they cancel each other out. This means VAT-registered UK importers effectively pay no net import VAT, and importantly, have no cash flow impact. If you're not VAT-registered, import VAT is a real cost — though below the £90,000 threshold, import volumes are typically modest enough for this to be manageable.
The UK-Vietnam Free Trade Agreement (UKVFTA) provides reduced or zero duty rates on Vietnamese-origin goods imported into the UK. To benefit, your goods must genuinely originate in Vietnam (meeting the Rules of Origin requirements), and your Vietnamese supplier must provide a EUR.1 certificate of origin at the time of shipment. You (or your freight forwarder) then declare the preferential tariff code on your UK customs entry. The savings can be substantial: clothing from Vietnam that would attract 12% MFN duty from China can attract as little as 0–9.6% under UKVFTA. If you're exploring Vietnam sourcing, we strongly recommend factoring UKVFTA savings into your cost modelling from the outset.
HMRC requires you to keep all records related to customs declarations for a minimum of four years. This includes: commercial invoices, packing lists, bills of lading or airway bills, customs import entries (C88/E2 documents from CDS), proof of origin certificates (EUR.1, GSP Form A, or supplier declarations), import VAT statements for PVA, and any correspondence with your supplier relating to the goods and their value. A practical approach is to create a folder per shipment containing all these documents, stored digitally. If HMRC conducts a post-clearance audit — which is increasingly common — having organised, complete records will resolve the matter quickly. Poor records are treated as an indicator of non-compliance and escalate scrutiny.
Technically, you can make customs declarations yourself if you're set up on HMRC's Customs Declaration Service. In practice, almost all UK businesses importing commercially use a licensed freight forwarder or customs broker — and for good reason. Freight forwarders have the expertise, software access, and HMRC relationships to clear goods efficiently, apply for duty suspensions, claim preferential rates correctly, and avoid the common classification and valuation errors that trigger post-clearance audits. The cost of a freight forwarder is typically £50–£200 per shipment declaration, which is money very well spent compared to the cost of getting it wrong. Epic Sourcing works alongside your freight forwarder and ensures the supplier-side documentation they need — commercial invoices, packing lists, certificates of origin — is accurate and complete before the goods leave the factory.
Whether you're importing your first container or optimising a supply chain you've been running for years, Epic Sourcing's UK team can help you get the sourcing, compliance, and duty management right — from factory to front door.
