Right, let's have a frank conversation about something that catches out a surprising number of UK importers — every single year. You've found a great supplier in China or Vietnam, negotiated a decent price, and mentally calculated your margins. Then the goods arrive at Felixstowe or Southampton, and the customs bill is significantly higher than you expected. Import duties, VAT, port fees, customs agent charges — they stack up fast, and if you haven't accounted for them properly, they can turn a profitable product into a money-losing headache.
This guide is for UK business owners, brand founders, and product importers who want a clear, no-nonsense understanding of how UK import duties and tariffs work in 2026 — what you'll pay, why you'll pay it, how to calculate your total landed cost, and how to use trade agreements like the UK–Vietnam Free Trade Agreement (UKVFTA) to reduce your duty bill legally.
At Epic Sourcing, we work with hundreds of UK businesses importing from China and Vietnam every year. We've seen the confusion that import duty calculations cause — and we've helped our clients navigate everything from standard ad valorem tariffs to complex rules of origin under free trade agreements. This guide captures what we know works.
UK import duties (also called customs duties or tariffs) are taxes charged by HMRC on goods brought into the United Kingdom from outside the country, calculated as a percentage of the customs value of the goods. The rates are set by the UK Global Tariff — the UK's independent tariff schedule, introduced after Brexit in January 2021 — and vary significantly depending on the type of product and its country of origin.
Since the UK left the EU's Customs Union at the end of 2020, UK importers have had to operate under a completely new tariff regime. The UK Global Tariff replaced the EU Common External Tariff, and whilst many rates remained similar, the administrative burden increased significantly. UK businesses importing from China and Vietnam now deal directly with HMRC under the Customs Declaration Service (CDS), managing their own customs declarations, commodity codes, and duty payments independently of EU processes. If you were importing before Brexit and haven't reviewed your duty rates since, there's a reasonable chance you're either overpaying — or worse, underpaying and accumulating compliance risk.
The bigger strategic picture in 2026 is this: import duties are one of the few significant, controllable costs in your supply chain. Freight rates fluctuate with market conditions, supplier pricing moves with exchange rates and raw material costs, but your duty rate is fixed in law — and it can be legally reduced through correct commodity code classification, free trade agreement preferences, and duty relief schemes. UK businesses that understand their duty position gain a meaningful competitive advantage over those who simply absorb whatever the customs agent bills them. With UK-China imports running at around £71 billion annually (Apr 2024–Mar 2025 figures), even small percentage improvements in duty optimisation across the UK importer base represent enormous savings. For your individual business, getting this right could be the difference between a viable margin and an unviable one.
The UK Global Tariff (UKGT) is the schedule of import duty rates applied to goods entering the UK from countries that don't have a preferential trade agreement with the UK. It's published and maintained by HMRC, and you can look up any product's duty rate using the UK Trade Tariff tool at trade-tariff.service.gov.uk. Every product imported into the UK is assigned a commodity code — a 10-digit number based on the international Harmonised System — and that code determines both your duty rate and any import licensing or restriction requirements.
Most UK import duties are ad valorem — meaning they're calculated as a percentage of the customs value of the goods. For example, if the customs value of your shipment is £10,000 and the duty rate is 6.5%, you pay £650 in customs duty. Some goods — particularly agricultural products, alcohol, and tobacco — attract specific duties, which are charged per unit of weight, volume, or quantity rather than as a percentage of value. A small number of products have combined duties — a percentage plus a specific element. For most manufactured goods imported from China and Vietnam, you'll be dealing with straightforward ad valorem rates.
This is where many importers get confused. The customs value is not just the price you paid your supplier. For most shipments into the UK, customs value is calculated on the CIF basis — Cost (the price paid to your supplier) + Insurance (the cost of insuring the goods in transit) + Freight (the cost of shipping the goods to the UK port of entry). This means your freight costs directly affect your duty bill. A shipment worth £8,000 in supplier cost, shipped with £1,500 freight and £50 insurance, has a customs value of £9,550 — and your duty is calculated on that higher figure.
Some importers are tempted to have suppliers write lower values on commercial invoices to reduce duty payments. This is customs fraud. HMRC actively investigates undervaluation, and the penalties — which include back-payment of all duties owed plus surcharges, and potentially criminal prosecution — far outweigh any short-term saving. Always declare the true transaction value of your goods.
On top of customs duty, you'll pay Import VAT at 20% (the standard UK rate). Import VAT is calculated on the customs value plus the customs duty already charged — so if your customs value is £9,550 and your duty is £650, your Import VAT is calculated on £10,200. For VAT-registered UK businesses, Import VAT is generally reclaimable as input tax on your VAT return, meaning it's a cash flow consideration rather than a permanent cost. If you use Postponed VAT Accounting (PVA) — which HMRC introduced for all UK importers — you can account for Import VAT on your VAT return rather than paying it upfront at the border, which significantly improves cash flow.
Getting your commodity code right is critically important. The 10-digit code determines not just your duty rate but also whether your goods are subject to anti-dumping duties, trade remedies, import licences, or other controls. Using the wrong code — even innocently — can result in underpayment of duty (which HMRC can recover for up to 3 years), overpayment (money you'll struggle to recover), or compliance issues. If you're importing a new product type for the first time, it's worth paying a customs consultant or freight forwarder to confirm the correct code, or applying to HMRC for a formal Advance Tariff Ruling (BTI).
Let's walk through a real example. Imagine you're importing 500 units of a branded gym bag from China. Here's how the duty calculation works:
| Step | Calculation | Amount |
|---|---|---|
| Supplier invoice value | 500 units × £14 FOB price | £7,000 |
| Add: sea freight (China to Felixstowe) | Approximate FCL/LCL rate | £850 |
| Add: cargo insurance | Approx 0.3% of goods value | £21 |
| Customs value (CIF) | £7,000 + £850 + £21 | £7,871 |
| Customs duty (gym bags — commodity code 4202) | Typically 3–3.7% of CIF value | ~£236–£291 |
| Import VAT base | CIF + Customs duty | ~£8,107–£8,162 |
| Import VAT at 20% | 20% of Import VAT base | ~£1,621–£1,632 |
| Total duty + VAT at border | Customs duty + Import VAT | ~£1,857–£1,923 |
In this example, a VAT-registered business will reclaim the Import VAT, leaving the real cost at just the customs duty of £236–£291. A non-VAT-registered business faces the full cash outlay at the point of import. This is why VAT registration and correct use of PVA matters so much for importers.
Before importing any new product, always check the duty rate using the official UK Trade Tariff tool at trade-tariff.service.gov.uk. Enter your commodity code (or search by product description) and select "Import into the UK" to see the current MFN rate, any preferential rates under trade agreements, and any trade remedies or anti-dumping measures that apply.
The rates below are indicative ranges based on the UK Global Tariff. Actual rates depend on the specific commodity code within each category — always verify the exact rate for your product on the UK Trade Tariff website. These are the standard MFN rates applied to imports from China. Vietnam may attract lower rates under UKVFTA.
| Product Category | Typical HS Chapter | MFN Duty Range (China) | Notes |
|---|---|---|---|
| Electronics & electrical goods | Ch. 84–85 | 0–3.7% | Many IT products at 0% under ITA |
| Clothing & apparel | Ch. 61–62 | 6.5–12% | Higher rates on synthetic fabrics |
| Footwear | Ch. 64 | 3.5–8% | Varies by upper material |
| Furniture & homeware | Ch. 94 | 0–5.7% | Wooden furniture often 0% |
| Toys & games | Ch. 95 | 0–4.7% | Safety regs (UKCA) also apply |
| Bags, luggage & accessories | Ch. 42 | 2.7–3.7% | Leather goods may be higher |
| Health & wellness products | Ch. 90, 33 | 0–6.5% | Medical devices may be 0% |
| Plastics & plastic articles | Ch. 39 | 0–6.5% | Varies widely by end use |
| Gym & sports equipment | Ch. 95 | 0–2.7% | Much sports equipment at 0% |
| Pet products | Ch. 42, 73, 39 | 0–4% | Depends on material classification |
| Sustainable packaging | Ch. 48, 39 | 0–6.5% | Paper packaging often lower |
One important caveat: some product categories attract anti-dumping duties or countervailing duties on top of the standard tariff rate. These are additional duties applied when HMRC determines that goods from a specific country are being sold below cost. Certain categories of ceramics, steel products, solar panels, and bicycles from China have historically attracted these measures.
One of the most strategically important decisions for UK importers in 2026 is whether to source from China, Vietnam, or both. From a tariff perspective, Vietnam has a significant structural advantage due to the UK–Vietnam Free Trade Agreement (UKVFTA). Here's how the two countries compare:
| Factor | China | Vietnam |
|---|---|---|
| Trade agreement with UK | None (MFN rates apply) | UKVFTA — preferential tariffs |
| Duty rate on clothing | 6.5–12% MFN | 0–3% under UKVFTA |
| Duty rate on footwear | 3.5–8% MFN | 0–3.5% under UKVFTA |
| Duty rate on electronics | 0–3.7% MFN | 0–3.7% (similar) |
| Anti-dumping risk | Higher — various sectors affected | Lower — fewer trade remedies |
| Rules of origin requirements | N/A — no FTA | Must meet UKVFTA origin rules |
| Sea freight transit time to UK | ~25–35 days | ~30–35 days |
| Typical MOQ | 100–1,000+ units | 200–2,000+ units (varies) |
| UK trade volume (2024) | ~£87bn total trade | ~£9.6bn total trade |
| Best for | Electronics, complex manufacturing, high-volume | Apparel, footwear, furniture, duty-sensitive products |
The duty saving from Vietnam can be substantial on certain product types. A UK importer bringing in £100,000 of clothing from China might pay £8,000–£12,000 in customs duty at the MFN rate. The same goods manufactured in Vietnam and qualifying under UKVFTA rules of origin could attract 0–3% duty — a saving that goes straight to your bottom line on every single shipment.
The vast majority of UK container imports from Asia arrive via Felixstowe (the UK's largest container port, handling approximately 40% of the country's containerised trade) or Southampton. Port charges, handling fees, and inland haulage costs from these ports should be included in your total landed cost calculation.
The UK–Vietnam Free Trade Agreement (UKVFTA) came into force on 1 May 2021 and is one of the most significant trade policy tools available to UK importers — yet the majority of UK businesses importing from Vietnam aren't fully utilising it. The agreement provides for immediate elimination of 65% of tariff lines on goods traded between the UK and Vietnam, rising to 99.2% elimination over time. That means a wide range of manufactured goods from Vietnam can enter the UK at 0% or significantly reduced duty rates, compared to the MFN rates that apply to the same goods from China.
To benefit from UKVFTA preferential tariff rates, your goods must meet the agreement's Rules of Origin requirements. The rules of origin define how much of the product must be made in Vietnam (or the UK) for it to "originate" from Vietnam. For most manufactured goods, this typically means significant processing or transformation must happen in Vietnam — not just final assembly of components sourced entirely from China.
To claim the preference at UK import, your Vietnamese supplier must provide either a EUR.1 movement certificate (issued by Vietnamese customs authorities), or an origin declaration on the commercial invoice. Your freight forwarder or customs broker then enters the appropriate preference claim on your customs declaration in CDS.
Claiming UKVFTA preference on goods that don't actually meet the rules of origin requirements is a compliance error — even if done unintentionally. HMRC can recover underpaid duties with interest, and repeated errors can trigger a formal audit. Always ask your Vietnamese supplier for written confirmation that the goods meet the applicable origin rules.
The UK formally joined the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) in December 2024. Both Vietnam and the UK are CPTPP members, which may provide an additional trade agreement framework alongside UKVFTA for certain products. The UK's growing network of FTAs with major Asian manufacturing countries represents a genuine competitive advantage for UK importers willing to do the work of understanding and utilising them.
Understanding your duty liability is only half the picture. You also need to have the right administrative infrastructure in place to import legally into the UK.
An Economic Operators Registration and Identification (EORI) number is a mandatory requirement for any business importing goods into the UK. It's a unique identifier that HMRC uses to track your imports and exports. Applying for a UK EORI number is free and straightforward via the GOV.UK website. Without a valid UK EORI number, your customs broker cannot process your import declaration and your goods will be held at the port.
Since March 2023, all UK customs declarations must be made through the Customs Declaration Service (CDS), which replaced the older CHIEF system. In practice, most businesses work with a licensed customs broker or freight forwarder who submits declarations on their behalf. However, as the importer of record, you remain legally responsible for the accuracy of the declaration — including the commodity code, customs value, and any preference claims.
VAT-registered UK importers can use Postponed VAT Accounting to account for Import VAT on their VAT return rather than paying it at the point of importation. This is a significant cash flow improvement — instead of paying Import VAT upfront, you declare it on your VAT return and reclaim it in the same period. To use PVA, ensure your customs declarations include the PVA indicator.
Many product categories imported into the UK must carry the UKCA (UK Conformity Assessed) mark. This replaced the CE mark for goods placed on the Great Britain market after 1 January 2021. Product categories requiring UKCA include electronics, toys, machinery, medical devices, construction products, and personal protective equipment. Non-compliant goods can be seized, refused entry, or require expensive recall.
If you're importing chemical substances, mixtures, or articles that contain chemicals into the UK, you may have obligations under UK REACH — the UK's independent equivalent of EU REACH. This applies to a broader range of products than many importers realise, including certain plastics, electronics, coatings, and cleaning products. Check whether UK REACH applies to your products via the Health and Safety Executive (HSE) guidance.
Import duties and VAT are the headline numbers, but they're not the only costs between your supplier's factory and your UK warehouse. Building this landed cost model before you commit to a supplier or a product is essential — it's the only way to know whether your margins actually work.
| Cost Category | What It Covers | Notes |
|---|---|---|
| Product cost (FOB) | Supplier price per unit, free on board | Paid to supplier |
| Inland freight (origin) | Factory to port of loading | Often included in FOB, but confirm |
| Ocean freight | FCL or LCL to Felixstowe/Southampton | Via freight forwarder — rates fluctuate |
| Marine insurance | Cargo insurance for transit | ~0.2–0.5% of cargo value |
| Customs duty | UK import duty on CIF value | Paid to HMRC via customs broker |
| Import VAT at 20% | VAT on (CIF + customs duty) | Reclaimable if VAT registered; use PVA |
| Customs clearance fees | Customs broker's declaration fees | £75–£200+ per shipment typically |
| Port / terminal handling | Destination handling at UK port | Included in some freight quotes |
| Delivery to UK warehouse | Inland haulage from Felixstowe or Southampton | £300–£800+ depending on destination |
| Inspection & testing (optional) | Pre-shipment QC inspection at origin | ~£250–£350 per inspection day |
| Total landed cost per unit | Sum of all above divided by units in shipment | This is your true cost basis |
The honest answer is that most first-time importers underestimate their landed cost by 15–30%. They see the FOB unit price, add a rough shipping number, and assume that's the total. In reality, customs duty, port fees, customs clearance charges, and UK delivery can add significantly to the cost — particularly for smaller shipments where fixed costs are spread over fewer units.
UK customs law includes several duty relief and suspension schemes that allow certain businesses to reduce or defer their import duty liability. These aren't loopholes — they're legitimate, HMRC-approved mechanisms designed to support specific business models.
IPR allows you to import goods without paying customs duty if you're going to process, manufacture, or repair them and then re-export the finished goods outside the UK. If you're importing components from China to incorporate into products that you sell internationally — including back into the EU — IPR could eliminate the duty on those imports entirely. There are specific authorisation requirements and record-keeping obligations, but for manufacturing businesses with significant re-export volumes, IPR can represent a very material saving.
A Customs Warehouse (or bonded warehouse) allows you to store imported goods without paying customs duty until the goods are removed for UK consumption. Duty is only paid when goods are released to free circulation. For businesses with long inventory holding periods, uncertain demand, or goods that may be re-exported, a customs warehouse can improve cash flow significantly.
If you've exported goods from the UK and they're returned — for example, customer returns on goods sold to EU buyers — you may be able to re-import them under Returned Goods Relief, paying no or reduced customs duty. There are time limits and conditions, but for businesses with international sales channels this is worth understanding.
The UK Government has established Freeport zones at various locations including Felixstowe/Harwich (Freeport East) and Southampton (Solent Freeport). Within designated Freeport zones, businesses can benefit from duty suspension, simplified customs procedures, and in some cases, enhanced capital allowances and business rates relief.
Duty relief schemes involve HMRC authorisations, record-keeping requirements, and potential liability if conditions aren't met. We strongly recommend taking advice from a qualified customs consultant or freight forwarder with duty relief expertise before applying.

The most reliable way is to use the UK Trade Tariff tool at trade-tariff.service.gov.uk. You'll need to identify or look up the commodity code for your product — this is a 10-digit number that describes the product category. The Trade Tariff tool will show you the current MFN duty rate (applicable to imports from China), any preferential rates under trade agreements (relevant if importing from Vietnam under UKVFTA), and any special measures like anti-dumping duties. If you're unsure about the correct code, your freight forwarder or a customs consultant can help classify it, or you can apply to HMRC for a formal Binding Tariff Information ruling. Getting this right matters — using the wrong code and underpaying duty can lead to HMRC recovery demands years later.
Import duty applies to commercial goods above a de minimis threshold. For commercial imports, the standard customs duty de minimis threshold in the UK is currently £135 — goods with a customs value below this are not subject to customs duty, though they may still be subject to VAT. However, this threshold is intended for non-commercial situations; if you're running a business and importing goods for resale or commercial use, you should assume customs duty applies. The UK Government has indicated plans to reform the low-value import VAT rules, so it's worth staying up to date with HMRC announcements if you're importing low-value goods at scale.
If your business is registered for VAT in the UK, you can reclaim Import VAT as input tax, in the same way you'd reclaim VAT on UK purchases. The key is to use Postponed VAT Accounting (PVA), which means Import VAT is declared on your VAT return rather than paid upfront at the port. Your customs broker must include the PVA indicator on your import declaration. HMRC provides monthly import VAT statements through your customs account that you use to reconcile your VAT return. Businesses not registered for VAT cannot reclaim Import VAT and should factor it as a true cost in their margins.
A commodity code is a standardised 10-digit number from the Harmonised System that describes exactly what a product is for customs purposes. It's used to determine your import duty rate, whether any import restrictions or licences apply, whether anti-dumping or countervailing duties are charged, and what preferential tariff rates are available. Using the wrong commodity code — even accidentally — can result in underpayment of duty (which HMRC can recover for up to three years, plus interest), overpayment, missed preference claims under trade agreements, or failure to meet import licensing requirements. Always take the time to correctly identify the commodity code when importing a new product type.
Anti-dumping duties are additional import charges applied on top of standard customs duty when HMRC determines that goods from a specific country are being sold into the UK at below their cost of production. The UK Trade Remedies Authority (TRA) investigates and recommends these measures. Several product categories imported from China historically attract anti-dumping duties — including certain types of steel, ceramics, bicycle components, and solar panels. Anti-dumping duties can be substantial — sometimes 20–50% or more on top of the standard rate — and can make otherwise viable products uneconomical to import from China. The solution for affected products is often to source from Vietnam, which typically is not subject to the same trade remedies.
