Everything UK importers need to know about calculating customs duty and import VAT — with worked examples, duty rates by category, and legitimate strategies to reduce your bill.
In summary: UK importers pay two separate charges when bringing goods from China or Vietnam — customs duty (a percentage set by the UK Global Tariff based on the product's HS code) and import VAT (20% on most goods, calculated on the duty-inclusive value). To calculate your total import cost, find your HS code, look up the duty rate, add duty to your CIF goods value, then calculate 20% VAT on top. This guide walks you through every step, with a worked example for common product categories.
Back in the day — pre-Brexit, pre-pandemic — importing from China felt relatively straightforward for British businesses. You'd find a supplier, agree a price, and the goods would arrive with a customs bill you sort of expected but never quite budgeted for properly. Twas' a simpler time.
Today, with the UK operating its own tariff schedule (the UK Global Tariff, separate from the EU's), every British importer needs to understand exactly what they'll pay before they place an order. Getting this wrong doesn't just hurt your margins — it can make a product completely unviable.
Having worked as a sourcing agent for small businesses for many years, the number one surprise our clients report isn't the quality of goods or the shipping time — it's the customs bill. So let's arm you with the tools to never be caught off guard again.
These two charges are completely separate — and many first-time importers confuse them. Here's the plain-English breakdown.
Customs Duty (also called import duty or tariff) is a tax charged on the value of imported goods. The rate is set by the UK Global Tariff and varies by product category — from 0% on some electronics to 12% on clothing. It's based on the HS (Harmonised System) code of your product.
Import VAT is charged at 20% on most goods imported into the UK. Unlike the duty rate, the VAT rate is consistent regardless of what you're importing (with a few exceptions like children's clothing and food). Crucially, import VAT is calculated on the duty-inclusive value of the goods — meaning you pay VAT on the cost of goods + shipping + insurance + the duty already charged.
Sourcing Hack #1: VAT-registered UK businesses can reclaim import VAT on their VAT return — so the real cost of import VAT is often £0 for VAT-registered companies. If you're not yet VAT registered and importing regularly, it's worth speaking to an accountant about whether registration makes sense for you.
Every product imported into the UK has a Commodity Code (also called an HS code or tariff code) — a 10-digit number that determines which duty rate applies. You look it up on the UK Trade Tariff tool, which is run by HMRC.
The process: describe your product accurately, navigate the tariff tool's category tree, find the 10-digit code, and look at the "Third Country Duty" rate — that's the rate that applies to goods from China, Vietnam, and most other countries outside the UK's trade agreements.
Sounds simple — and it usually is. But the devil's in the detail. A gym bag is different from a sports bag, which is different from a rucksack. Each could carry a different duty rate. Getting the code wrong can mean underpaying (and facing penalties from HMRC) or overpaying. We always recommend checking the exact commodity description with a customs broker if you're unsure.
Sourcing Hack #2: When you're at the product research stage, use the UK Trade Tariff tool to check the duty rate before you even request a quote from a supplier. Build the landed cost calculation into your margin model from day one. You'd be amazed how many UK importers only check the duty rate after their first shipment arrives.
Here's the step-by-step calculation every UK importer needs to know. Let's use a practical example: you're importing 1,000 stainless steel travel mugs from China at a factory price of £3.50 each, with sea freight of £350 and marine insurance of £80.
The customs value for UK imports is the CIF value — Cost, Insurance, Freight. So: £3,500 (goods) + £350 (freight) + £80 (insurance) = £3,930 CIF value.
Travel mugs (stainless steel, non-electric) typically attract a Third Country Duty rate of around 3%. So: £3,930 × 3% = £117.90 customs duty.
Import VAT is charged on the CIF value + customs duty: (£3,930 + £117.90) × 20% = £809.58 import VAT. If you're VAT registered, you'll reclaim this on your VAT return.
Don't forget: customs broker fees (typically £50–£150 per shipment), port handling charges, and delivery to your warehouse. In our example: £3,930 + £117.90 + £100 (broker) + £200 (delivery) = £4,347.90 landed (ex-VAT). That's £4.35 per mug — significantly more than your £3.50 ex-works price.
Sourcing Hack #3: Always build a landed cost model in a spreadsheet before you commit to a product. Include: factory price, freight, insurance, customs duty, broker fees, and last-mile delivery. Then work backwards from your target retail price to confirm your margin. At Epic, we build this model for every client product as part of our White Label and Private Label sourcing process.
Yes — not everything attracts duty. Many consumer electronics (laptops, tablets, certain computer components) carry a 0% third-country duty rate. Some raw materials and industrial inputs are also duty-free. Agricultural products, clothing, footwear, and most finished consumer goods typically carry positive duty rates ranging from 2% to 12%.
It's also worth knowing about UK trade agreements. The UK-Vietnam Free Trade Agreement (UKVFTA) provides preferential duty rates for goods manufactured in Vietnam that meet rules of origin requirements. This is one of the reasons many UK importers are adding Vietnam to their supply chain — and it's especially relevant if you're sourcing seasonal goods. Our guide to sourcing outdoor and garden products from China to the UK shows how the duty rate varies dramatically by category.
Goods valued under £135 entering the UK are subject to a different VAT collection system — the supplier (or online marketplace) is responsible for collecting and remitting UK VAT at the point of sale, rather than at the border. This primarily affects direct-to-consumer eCommerce goods from Chinese platforms like Shein or Temu.
For B2B importers buying in bulk — which is Epic's world — the £135 threshold is largely irrelevant. You'll nearly always exceed this value, and customs duty + import VAT are handled at the border by your customs broker on formal entry via the Customs Declaration Service (CDS).
Sourcing Hack #4: Use a duty deferment account if you're importing regularly. Instead of paying duty and VAT at the point of import, you pay once a month by direct debit. This massively improves your cash flow — especially useful if you're importing multiple shipments per month. Your customs broker or freight forwarder can help you set one up with HMRC.
Here's a quick reference for popular product categories Epic clients source from China and Vietnam. Always verify the exact rate for your specific commodity code on the UK Trade Tariff tool.
Clothing and apparel: 12% — one of the highest duty rates in the UK Global Tariff. A key reason to explore white label sourcing from Vietnam under UKVFTA preferential rates.
Footwear: 8–17% depending on construction and materials.
Gym equipment (barbells, plates, benches): 0–2.7%
Electronics accessories (phone cases, cables, chargers): 0–3.7%
Plastic housewares (bottles, containers, kitchenware): 2.7–6.5%
Wooden furniture: 0–5.6%
Garden furniture (rattan/metal): 0–5.6%
Toys: 4.7%
Cosmetics and beauty products: 0–6.5%
There are legitimate strategies UK importers use to reduce their duty burden — none of which involve doing anything dodgy. This is just smart sourcing strategy.
Source from Vietnam for UKVFTA products: Vietnam has a free trade agreement with the UK, meaning many Vietnamese-manufactured goods enter the UK at 0% duty (subject to rules of origin). Clothing, footwear, and furniture are particularly advantageous. At Epic, we source from Vietnam for exactly this reason — explore our Secret Label Package to see how this works in practice.
Check for UK tariff suspensions: The UK government occasionally suspends duties on certain inputs that aren't manufactured domestically. Worth checking if you import raw materials or components.
Use Inward Processing Relief (IPR): If you're importing goods to process them in the UK, you may be able to defer or suspend duty on the imported inputs.
Review your commodity codes regularly: Duty rates change. The UK Global Tariff is reviewed and updated, so always recheck when placing a new product order.
UK import duty from China varies by product and is set by the UK Global Tariff (Third Country Duty rates). Common rates range from 0% for many electronics to 12% for clothing. Find the exact rate for any product using your commodity code on the UK Trade Tariff tool.
Yes — import VAT of 20% applies to most goods imported into the UK from China. It's calculated on the CIF value of your goods plus any customs duty already charged. VAT-registered businesses can reclaim import VAT on their VAT return, making the effective cost zero.
For commercial imports, there is no duty-free allowance. Commercial goods are subject to UK customs duty and import VAT regardless of value (with the £135 threshold affecting how VAT is collected on low-value consignments, not whether it's charged).
Technically no, but practically yes. Submitting customs declarations through the CDS requires specialist software and authorisation. Unless you're a large company with a dedicated customs team, you'll use a customs broker or freight forwarder who handles declarations on your behalf.
Most customs declarations are processed within hours — often automatically. Physical inspections by HMRC are relatively rare for established importers, but can add 1–3 days to clearance time when they do occur.
In practice, these terms are used interchangeably. "Tariff" typically refers to the rate schedule — the UK Global Tariff — that sets out those duty rates. "Duty" is the actual charge you pay at import based on that rate.
Absolutely — most freight forwarders offer customs brokerage as part of their service. Fees typically run to £50–£150 per shipment. We walk our clients through freight and customs as part of our complete importing guide.
