Right, let's have a frank conversation. UK import customs has never been simple — but 2026 has thrown yet another layer of complexity at importers already dealing with Brexit red tape, Rising costs, and global supply chain turbulence. The Low Value Imports (LVI) reform, combined with the full rollout of the Customs Declaration Service (CDS), means the rules of the game have changed significantly. If you're still operating on assumptions you formed in 2021 or 2022, there's a meaningful chance you're paying too much, filing incorrectly, or leaving serious duty savings on the table.
This guide is for UK business owners, brand founders, and import managers who source goods from China, Vietnam, or elsewhere in Asia. It covers everything: what changed, what it means for your business, how to get your customs house in order, and — crucially — how to take advantage of the UK–Vietnam Free Trade Agreement (UKVFTA) to slash your import duty bill when sourcing from Vietnam.
The Low Value Imports (LVI) reform refers to the UK Government's overhaul of how customs declarations and VAT are handled for goods valued below the £135 import threshold. The reform tightened declaration requirements, closed loopholes that allowed cheap imported goods to bypass proper customs scrutiny, and placed greater compliance obligations on both overseas sellers and UK importers. For UK businesses importing commercial consignments from Asia, the practical effect is a stricter, more thoroughly documented customs process — with stiffer penalties for errors.
Let's start with a bit of history. When the UK left the EU's customs union at the end of 2020, it inherited a set of import rules that — in practice — had significant grey areas around low-value consignments. The £135 threshold became a focal point: goods below this value didn't attract import duty (though VAT still applied), and the mechanisms for collecting that VAT on overseas-sold B2C goods were inconsistent and widely abused.
The LVI reform closed several of these gaps. The headline changes that affect UK importers sourcing from Asia in 2026 are:
Before vs After: Key Customs Changes for UK Importers
| Area | Pre-Reform (2021–2024) | Post-Reform (2025–2026) |
|---|---|---|
| Customs system | CHIEF (legacy) + early CDS | CDS only — CHIEF retired |
| Low-value declarations | Simplified / reduced data | Full commodity code required |
| VAT enforcement | Moderate — PVA widely used | High — PVA audits common |
| Border checks | Phased in, incomplete | Full documentary + physical |
| Origin documentation | Lightly enforced | Actively audited by HMRC |
| UKVFTA claims | Available, rarely used | Well-known, actively claimed |
If you're a UK business importing goods from China or Vietnam for the first time — or if you've always left this entirely to a freight forwarder without really understanding what they're doing — here's a plain-English walkthrough of what actually happens when your container arrives at Felixstowe or Southampton.
Your supplier in Guangzhou, Shenzhen, Ho Chi Minh City or wherever loads your goods into a container (FCL) or consolidates them into a shared container (LCL). Sea transit to Felixstowe takes approximately 25–35 days from China and 30–35 days from Vietnam. Your freight forwarder issues a Bill of Lading — this is the key ownership document for your goods.
Before the vessel docks, your customs broker submits an Entry Summary Declaration (ENS) via the UK's Import Control System. This gives Border Force advance notice of what's coming in. This step happens automatically if you're using a competent broker — but it's worth confirming it's being done.
Your customs broker submits a full import declaration through the Customs Declaration Service (CDS). This includes your EORI number, the commodity code(s) for your goods, country of origin, customs value (transaction value in £), and any preferential tariff claims (e.g. UKVFTA for Vietnam-origin goods). This is where most errors — and most money — are made or lost.
HMRC's automated systems assess the declaration. The vast majority of consignments receive a "Route 1" clearance — meaning they're waved through with no physical inspection. Some are routed for documentary checks (Route 2) or physical inspection (Route 3). Goods that are consistently well-documented and from known importers rarely hit Route 3.
Once cleared, your import duty (if applicable) and import VAT (20%) are calculated and collected. Most established importers use a duty deferment account, which means you pay monthly in arrears rather than per shipment. VAT is typically reclaimed via your VAT return if your business is VAT-registered. The net import duty cost is the real cash outflow you need to plan for.
Once cleared, your goods are released from the port and delivered to your warehouse or 3PL. From Felixstowe or Southampton to a UK distribution centre, this typically takes 1–3 days depending on your logistics arrangements. Your customs broker will provide you with the C88/E2 entry acceptance notice — keep this for your records.
Keep a complete file for every shipment: commercial invoice, packing list, Bill of Lading, EORI confirmation, commodity code classification record, and any preferential origin documents. HMRC can audit up to four years back. If you can't produce documentation to support your customs declarations, you're liable for any underpaid duty — plus interest and potential penalties.
An Economic Operators Registration and Identification (EORI) number is your business's unique identifier in the UK customs system. Without one, you cannot legally import goods into the UK on a commercial basis. This is non-negotiable.
Your UK EORI number begins with "GB" and is based on your VAT number (for VAT-registered businesses) or your company registration number. If you're importing commercial goods and you don't have an EORI, stop everything and apply for one now via HMRC — it's free and can be done online, typically taking 5–7 working days.
Many sole traders and small businesses importing for the first time are caught out by not having an EORI. Your freight forwarder cannot file a proper import declaration in your name without it. Some forwarders will use their own EORI "temporarily" — but this creates a legal situation where you don't formally own the import record, which can cause problems if HMRC later audits the shipment.
If your business moves goods between Great Britain (England, Scotland, Wales) and Northern Ireland, you need both a GB EORI and an XI EORI. The Northern Ireland Protocol (now the Windsor Framework) means goods crossing the Irish Sea still require specific documentation. For most England, Scotland, or Wales-based importers bringing goods in from Asia, a single GB EORI is sufficient.
Your customs value is the basis on which import duty is calculated. For most importers, this is the "transaction value" — what you actually paid your supplier, converted to GBP at HMRC's published exchange rate. Here's where importers frequently get caught out: the customs value must include all costs up to the point of entry into the UK. For CIF (Cost, Insurance, Freight) terms, this means the full CIF value. For FOB terms, you need to add freight and insurance costs to arrive at the correct customs value. Getting this wrong — even accidentally — is an error that HMRC takes seriously.
The Customs Declaration Service is the HMRC platform through which all UK import and export declarations are now filed. CHIEF, the legacy system that processed declarations for decades, was fully retired in 2024. CDS is more data-rich than CHIEF — declarations now require more fields, more precision in commodity code classification, and more detailed valuation information.
As an importer, you don't typically interact with CDS directly — your customs broker or freight forwarder does. But you need to understand what information they need from you to file accurately:
Use HMRC's online Trade Tariff tool at trade-tariff.service.gov.uk. Enter a product description and it'll suggest applicable codes. For anything complex — textiles, electronics, chemical compounds — we strongly recommend getting a formal tariff classification ruling from HMRC (called a BTI — Binding Tariff Information). This takes about 30 days but protects you from future disputes. At Epic Sourcing, we help clients classify products correctly as part of our sourcing process.
Here's what most guides get wrong: they list duty rates without explaining how to think about landed cost. Landed cost is the total cost of a product by the time it's on your warehouse shelf in the UK, ready to sell. It's what actually determines your margins. Understanding it properly means no nasty surprises.
The UK applies the UK Global Tariff (UKGT) to imports from countries without a preferential trade deal — which includes China (there is currently no UK-China free trade agreement). Duty rates vary significantly by product category:
| Product Category | Typical UKGT Rate (China) | Example Products |
|---|---|---|
| Clothing & Apparel | 12% | T-shirts, jackets, sportswear |
| Footwear | 8–17% | Trainers, leather shoes, sandals |
| Consumer Electronics | 0–4% | Gadgets, accessories, chargers |
| Furniture & Home Goods | 0–5.5% | Chairs, tables, lighting |
| Toys & Games | 0% | Toys, board games, dolls |
| Gym Equipment | 2.7–4.7% | Weights, resistance bands, machines |
| Health & Beauty | 0–6.5% | Cosmetics, supplements, devices |
| Plastics & Packaging | 3.5–6.5% | Containers, bags, packaging |
Rates are indicative. Always verify against the current UK Trade Tariff for your specific commodity code.
Landed Cost Calculation (CIF Basis)
Product Cost (FOB): £10,000
+ Sea Freight (China to Felixstowe): £800
+ Marine Insurance (0.3% CIF): £32
= CIF Value (Customs Value): £10,832
× Import Duty (e.g. 12% for clothing): £1,299.84
+ Import VAT (20% on CIF + Duty): £2,426.37 (reclaimable)
+ Customs Broker Fees: £150–£350
+ Port Handling & THC: £200–£450
Total Landed Cost (excl. reclaimable VAT): ~£12,500–£13,000
The key insight here: for a clothing importer, the 12% duty adds a meaningful chunk to your cost base. For a business doing £500,000 of annual imports from China, that's £60,000 per year in import duty. This is precisely why understanding UKVFTA — and sourcing from Vietnam where possible — can transform your margin profile.
Most UK VAT-registered importers use Postponed VAT Accounting, which allows you to account for import VAT on your VAT return rather than paying it upfront at the border and waiting to reclaim it. This is a significant cash flow benefit — for a business importing £1m of goods per year, PVA can mean tens of thousands of pounds in working capital that stays in your business. Confirm with your accountant that you're set up for PVA correctly on all your import declarations.
The UK–Vietnam Free Trade Agreement (UKVFTA) came into force in January 2021, and it's still one of the most underused tools available to UK importers. Here's the honest answer: most UK businesses either don't know it exists, don't know how to claim it, or work with factories that aren't set up to provide the necessary origin documentation. At Epic Sourcing, we've helped dozens of UK brands start sourcing from Vietnam specifically because the duty savings are so significant.
The UKVFTA eliminates or significantly reduces import duties on goods originating in Vietnam. At the time of signing, 65% of UK tariff lines were immediately reduced to zero. By 2026, the agreement covers 99.2% of UK-Vietnam trade — meaning almost everything sourced from Vietnam qualifies for reduced or zero duty when proper origin documentation is provided.
| Product Category | China Rate (UKGT) | Vietnam Rate (UKVFTA) | Annual Saving on £100k Imports |
|---|---|---|---|
| Clothing | 12% | 0–9.6% | Up to £12,000 |
| Footwear | 8–17% | 0–8% | Up to £17,000 |
| Furniture | 0–5.5% | 0% | Up to £5,500 |
| Electronics | 0–4% | 0% | Up to £4,000 |
| Bags & Accessories | 3.7% | 0% | £3,700 |
Savings are illustrative based on CIF value of £100,000. Actual rates depend on specific commodity codes. Vietnam UKVFTA rates reflect 2026 staging.
To claim UKVFTA preference, you need to demonstrate that your goods genuinely originate in Vietnam — i.e., they were substantially manufactured there, not simply assembled or transshipped. The rules of origin requirements under UKVFTA vary by product but typically require:
Be very careful about goods from China that are sent to Vietnam for minor processing before being exported to the UK. "Origin washing" — adding minimal value in Vietnam to claim UKVFTA preference on what are essentially Chinese-origin goods — is a customs fraud that HMRC and Vietnamese customs authorities are actively investigating. The consequences include back-duty demands, penalties, and potentially criminal charges. Your Vietnamese factory should be able to provide a full bill of materials showing where value is genuinely added.
UK–Vietnam bilateral trade reached approximately £9.6bn in 2024. Vietnam is now one of the UK's most important manufacturing partners for apparel, footwear, electronics, and furniture. Major UK and international brands have shifted meaningful production volumes from China to Vietnam over the past five years, driven by a combination of UKVFTA duty savings, competitive labour costs, improving manufacturing quality, and supply chain diversification. For UK importers, Vietnam now represents one of the most compelling sourcing propositions globally.
This is where most UK importers lose the most money. Not through deliberate fraud, but through avoidable errors that compound over time. Here are the mistakes we see most often at Epic Sourcing, and what to do instead.
The commodity code determines your duty rate, your VAT treatment, and whether your goods need a licence or certificate. A wrong code can mean underpaying duty (liability) or overpaying it (margin erosion). We've seen businesses paying 12% duty on goods that qualified for a 0% rate simply because the broker used a generic code. Get a BTI from HMRC for any product you import regularly in meaningful volumes.
Asking your supplier to write a lower value on the commercial invoice to reduce your duty and import VAT liability is customs fraud. Full stop. HMRC has access to transaction data, price databases, and intelligence from overseas customs authorities. If caught, you face retrospective duty demands, penalties of up to 100% of the duty evaded, and potential prosecution. It is not worth it.
As noted above, HMRC is now actively auditing UKVFTA preferential tariff claims. If you claim Vietnam origin preference and can't produce a valid statement of origin from a REX-registered exporter with supporting manufacturing evidence, you'll owe all the back duty as if you'd imported from China — potentially with penalties on top.
Many importers bundle customs clearance with their freight forwarding, treating it as a commodity service. The reality is that freight forwarding and customs brokerage are distinct skills. Choosing a freight forwarder based on the cheapest sea freight rate and then letting them handle your customs declarations without scrutiny is a recipe for errors. Consider using a dedicated customs broker for complex or high-value shipments.
The UK applies anti-dumping duties (ADD) on certain product categories from specific countries, on top of standard import duty. These can be substantial — ranging from a few percent to well over 50% for some steel products. Check the UK Trade Tariff for your commodity code and country of origin before your first shipment. An unexpected ADD on a large consignment can wipe out your entire margin.

Learn about Secret Label sourcing →Beyond our core sourcing packages, we also offer standalone services relevant to UK customs:
Technically, yes — you can file your own import declarations through the Customs Declaration Service if you're a direct trader. However, CDS requires software integration and a reasonable understanding of commodity codes, customs valuation, and UK trade tariff procedures. For most small and medium UK importers, using a licensed customs broker is far more practical and cost-effective. Broker fees typically range from £50 to £250 per declaration, depending on complexity. Given that a customs error can cost you multiples of that in retrospective duty, it's generally excellent value.
Physical inspections at UK ports are relatively rare for well-documented consignments, but they do happen. Border Force will take samples from your container and check them against your documentation — commodity codes, declared value, and any safety or compliance documentation (UKCA marking certificates, for example). The process typically takes 2–5 working days. Your goods will be released once the inspection is complete, unless there's a material discrepancy. The best way to avoid inspections is robust, consistent documentation on every shipment — the more predictable your import profile, the less likely you are to be flagged.
No. Import VAT is only reclaimable through your VAT return if your business is VAT-registered. For non-VAT-registered businesses, import VAT is a real cash cost that forms part of your landed cost. If your annual taxable turnover is approaching the VAT registration threshold (currently £90,000), importing goods may push you over it — or may make it financially worthwhile to register voluntarily before you're legally required to, specifically to access input VAT recovery on your imports. Speak to an accountant about your specific situation.
Almost certainly not. UKVFTA preferential rates require that goods genuinely originate in Vietnam — meaning they were substantially manufactured or transformed there. Goods manufactured in China and shipped through Vietnam without meaningful value-add do not qualify, regardless of where they were dispatched from. Claiming UKVFTA preference on such goods is origin washing, which is treated as customs fraud by HMRC. If you're sourcing from a factory that does some work in both China and Vietnam, the rules of origin test will depend on where sufficient manufacturing transformation occurred — your customs broker can advise based on your bill of materials.
HMRC can generally audit import declarations going back four years. In cases of deliberate fraud or dishonesty, this extends to twenty years. This means errors you made in 2022 or 2023 are still within the standard audit window. If you've recently reviewed your past declarations and noticed errors — wrong commodity codes, undervalued invoices, unjustified preferential tariff claims — you should consider making a voluntary disclosure to HMRC. Voluntary disclosures are treated significantly more favourably than errors discovered during an audit, and penalties are typically reduced substantially. Speak to a customs compliance specialist or solicitor before making any disclosure.
The 2026 LVI reforms mean there's no more hiding behind grey areas. But they've also created a cleaner system where the businesses that get their customs house in order — and take advantage of UKVFTA — will have a meaningful cost advantage over those who don't.
At Epic Sourcing, we work with UK importers to build supply chains that are not just cost-competitive, but customs-compliant from day one. Whether you're sourcing from China, Vietnam, or both, we'll help you structure your imports to minimise duty, maximise compliance, and never get a nasty surprise from HMRC.
