Post-Brexit Guide for UK Online Sellers: Duties, VAT, and Customs in 2026
Brexit changed everything for UK e-commerce businesses selling to Europe. Five years on, many sellers still get it wrong — paying too much, losing packages at customs, or facing VAT penalties. Here is the definitive guide.
The Post-Brexit Reality for UK E-Commerce in 2026
When the UK left the EU's single market and customs union on 1 January 2021, it fundamentally changed the rules for every UK business selling to European customers. Five years on, the impact is still misunderstood, mismanaged, or simply ignored by many UK online sellers.
The EU is 450 million consumers in one of the world's richest markets. UK brands had frictionless access to it for nearly three decades. Since Brexit, every shipment from the UK to the EU is a customs export from the UK side and a customs import into the EU. Every parcel crossing the Channel potentially triggers customs duties, EU VAT obligations, and formal customs declarations that did not previously exist.
Tens of thousands of UK e-commerce businesses saw their EU sales collapse in January 2021. Some never recovered. Others rebuilt with the right systems and are now selling into Europe profitably and compliantly — the friction is real, but manageable for sellers who understand the rules.
This guide covers everything UK online sellers need in 2026: what changed, EU VAT obligations, the IOSS and OSS schemes, customs documentation, duties, country-specific requirements, and how to configure your Shopify store for compliant EU selling.
What Changed on 1 January 2021
Understanding the before/after clearly prevents the most common post-Brexit compliance errors.
Before Brexit (UK in EU single market):
- No customs declarations required for goods moving between the UK and EU
- No import duties on UK-origin goods entering the EU
- UK VAT registration covered UK sales; EU distance selling rules applied with per-country thresholds
- Parcels moved between the UK and EU as if within a single customs territory — as freely as London to Manchester
- Every UK-to-EU shipment is a formal customs export from the UK and a customs import into the EU
- Customs export declarations are required in the UK for all commercial shipments above £135
- Customs import declarations are required at the EU border — typically handled by your carrier
- Import duties apply to goods that do not qualify as UK origin under the Rules of Origin rules
- EU VAT must be collected at EU rates from EU customers and remitted to EU tax authorities
- Customs clearance delays are now possible (and occasional) for every EU shipment
EU VAT: Your Most Important Post-Brexit Obligation
The Old Distance Selling Rules No Longer Apply
Before Brexit, UK sellers used EU distance selling thresholds — sell below the threshold to a specific country (e.g., €35,000 to Germany) and charge UK VAT; exceed the threshold and register for VAT in that country. This system was already replaced in July 2021 by the EU's new One Stop Shop (OSS) scheme — but UK sellers left the old distance selling system when the UK left the EU, so OSS is the relevant framework from day one.
The One Stop Shop (OSS) Scheme: Single EU VAT Registration
OSS allows businesses outside the EU to register for EU VAT in a single EU member state and use that registration to account for VAT on B2C sales across all 27 EU member states.
Without OSS: a UK seller with customers in France, Germany, Italy, Spain, Netherlands, Ireland, and Belgium would theoretically need seven separate VAT registrations, seven different filing frequencies, seven different payment schedules, and compliance with seven different national VAT rules. This is impractical for most UK sellers.
With OSS: register in one EU member state. File one quarterly VAT return covering all EU B2C sales. Make one quarterly payment to your OSS country's tax authority. The OSS country distributes the VAT to each member state's tax authority.
Who must register for EU OSS?
Registration is required if your B2C sales to EU customers exceed €10,000 per year across all EU countries combined. Below €10,000, you may use your UK VAT registration for all EU sales (though this is a transitional relief that may not persist).
If your EU sales are B2B (to VAT-registered EU businesses), reverse charge applies — the EU buyer accounts for VAT in their country and you do not need OSS for those sales. Always verify whether your EU customer is VAT-registered before applying reverse charge.
How to register for EU OSS:
Choose a registration country. UK businesses most commonly choose:
- Ireland: English language, familiar common law system, good HMRC-to-Revenue relationship, short flight from London
- Germany: Largest EU e-commerce market, worth being registered there anyway for other purposes
- Netherlands: Good English proficiency in the tax authority, efficient registration process
Charging VAT correctly under OSS:
Under OSS, you charge the VAT rate of the customer's country — not your registration country's rate. This is a fundamental change from the old UK distance selling rules.
| Country | Standard VAT Rate |
|---|---|
| France | 20% |
| Germany | 19% |
| Italy | 22% |
| Spain | 21% |
| Netherlands | 21% |
| Ireland | 23% |
| Poland | 23% |
| Sweden | 25% |
| Denmark | 25% |
| Luxembourg | 17% |
Filing and payment:
File a quarterly OSS return showing sales and VAT collected by EU country. The return is filed through your OSS registration country's online portal. Pay the total VAT collected in one payment. The OSS country distributes funds to the other member states on your behalf.
Return deadlines: the end of the month following each calendar quarter (31 January, 30 April, 31 July, 31 October).
The Import One Stop Shop (IOSS): For Parcels Below €150
IOSS is a separate, specific scheme for imports of goods from outside the EU with a declared value below €150. It was introduced specifically to handle the post-Brexit and e-commerce parcel volume challenge.
How IOSS works:
Register for IOSS in one EU member state (the same country as your OSS registration is practical). When you make a B2C sale below €150 to an EU customer:
- Collect the EU VAT at the correct country rate at checkout
- Display the VAT-inclusive price clearly
- Mark the parcel with your IOSS number on the customs documentation
- The IOSS number signals to EU customs that VAT has been collected at point of sale — the parcel clears customs without additional VAT assessment
- File a monthly IOSS return and remit the collected VAT
Without IOSS, your parcel arrives at EU customs without a VAT-paid indicator. The postal carrier or customs authority assesses VAT on the parcel before delivery. The customer receives a notice: "Your parcel is held at customs. Pay €[X] to release it."
This process:
- Delays delivery by 1–10 days during busy periods
- Surprises the customer with an unexpected charge they did not budget for
- Frequently results in parcel refusal — the customer declines to pay and the parcel is returned
- Generates a customer service complaint regardless of the outcome
- Costs you the product, the shipping, and potentially the return shipping
Monthly IOSS filing: Unlike the quarterly OSS return, IOSS returns are filed monthly. This is additional administrative overhead — factor it into your decision about whether IOSS is worth registering for (it almost always is once your EU sales are meaningful).
Import Duties: Rules of Origin Under the TCA
The UK-EU Trade and Cooperation Agreement (TCA), which came into force on 1 January 2021, established zero tariffs on goods traded between the UK and EU — but only for goods that meet the Rules of Origin requirements.
What Rules of Origin Mean
For goods to qualify as "UK origin" under the TCA and enter the EU duty-free, they must be either:
The critical misconception: Goods imported from China, India, Bangladesh, Turkey, or any other non-UK, non-EU country and then reshipped from the UK to the EU are not UK origin. They do not qualify for zero tariffs under the TCA.
If you source products from Asia and sell them to EU customers, you may face EU import duties at the standard MFN (Most Favoured Nation) rates — which the EU would charge on the same goods from any country without a preferential trade agreement.
Common duty rates for goods without UK origin preference:
| Category | EU MFN Duty Rate |
|---|---|
| Clothing and apparel | 12–32% |
| Footwear | 4–17% |
| Electronics | 0% (many categories) |
| Furniture | 0–5.6% |
| Toys | 0–4.7% |
| Cosmetics | 0–6.5% |
| Accessories (leather, bags) | 2.7–3.7% |
How to Check Your Products' Duty Rates
For products where duties apply, your options are:
- Price EU customers to include the expected duty in the product price (build it in)
- Use Shopify's Duties and Import Taxes feature to collect duties at checkout (transparent pricing, no delivery surprise)
- Accept that some EU customers will face unexpected duties and manage the resulting complaints
Customs Documentation Requirements
Every commercial shipment from the UK to the EU requires accurate customs documentation. Missing or incorrect documentation is the second most common cause of EU delivery failures (after VAT surprise charges).
Required Documents for Every UK-to-EU Shipment
Commercial invoice: Every shipment needs a commercial invoice containing:
- Seller: your business name, address, country (United Kingdom)
- Buyer: customer name, address, country (the EU member state)
- Detailed description of each item — "women's cotton dress, navy, size 12" not "clothing" or "merchandise"
- HS commodity code for each item
- Country of origin for each item (UK, China, India — wherever it was made)
- Quantity per item
- Unit value and total value per item in the invoiced currency
- Total invoice value and currency
- Your IOSS number (if applicable for below-€150 parcels)
- Your UK EORI number
Accurate declared value: Always declare the actual commercial value — what the customer paid for the goods. Never understate value to reduce duties. EU customs authorities have data-matching tools, and misdeclaration is a criminal offence in some member states. It also invalidates your shipping insurance.
Specific carrier documentation:
- Royal Mail: CN22 (under £270) or CN23 (£270 and above) customs declaration form, generated through Royal Mail Click & Drop or your shipping software
- DHL/FedEx/UPS: Commercial invoice integrated into their electronic customs declaration systems — typically generated through their shipping portals
HS Commodity Codes — Get These Right
HS codes are 6-digit (or longer at national level) codes that classify every traded product globally. Customs authorities use HS codes to:
- Determine applicable duty rates
- Apply product-specific regulatory requirements
- Generate customs statistics
Use the UK Trade Tariff tool (trade-tariff.service.gov.uk) to find the correct code for each product. When in doubt, err on the side of a more generic code for your product category — an incorrect HS code that results in under-collection of duties can trigger post-clearance assessment by EU customs.
Country-Specific Considerations for EU E-Commerce
Different EU markets have different requirements beyond the standard customs and VAT framework.
Germany: Extended Producer Responsibility (EPR)
Germany has strict Extended Producer Responsibility laws:
LUCID registration (packaging): Any business selling packaged goods to German consumers must register with the LUCID Packaging Register (lucid.rpg.de) and join a dual system operator (like DSD, Interseroh, or Reclay). Annual fees are based on packaging volume.
ElektroG (electronics): Electrical and electronic products require registration with the Stiftung EAR before being placed on the German market.
Non-compliance with German EPR laws is enforced by the Packaging Central Authority (ZKR) and can result in a sales ban on all marketplaces and e-commerce platforms in Germany. Amazon, eBay, and many payment processors actively remove non-compliant sellers.
German VAT rate: 19% standard, 7% reduced (food, books, some cultural items).
Buyer behaviour note: German consumers have the highest return rates in Europe — 40%+ in fashion and footwear is not unusual. Factor return logistics costs into your German pricing.
France: EPR and Triman Labelling
France requires EPR registration for packaging (obligatory since January 2022) through licensed compliance schemes (Citeo, Re-cycle, etc.).
Triman logo: Products subject to EPR in France must carry the Triman logo (indicating the product should be sorted for recycling). This applies to packaging, textiles, furniture, and electrical equipment.
France also has a strong language requirement for consumer product labels — French-language descriptions are required on products sold to French consumers, though e-commerce product pages have more flexibility than physical labels.
French VAT rate: 20% standard, 5.5% reduced (food, books), 2.1% super-reduced (medicines, press).
Ireland: Most Accessible EU Market for UK Businesses
Ireland is typically the easiest EU market for UK businesses to enter:
- English language
- Common law legal system familiar to UK businesses
- Close cultural and business ties with the UK
- Short shipping times (overnight by express carrier)
Irish VAT rate: 23% standard, 13.5% reduced (fuel, construction), 9% (tourism and hospitality, certain food service).
Netherlands: Gateway to EU Logistics
The Netherlands hosts Rotterdam, Europe's largest port, and Schiphol Airport, a major air freight hub. Dutch consumers have high e-commerce adoption and above-average spending per online transaction.
For UK sellers considering establishing an EU distribution warehouse, the Netherlands is the most popular choice — excellent logistics infrastructure, central EU location, and business-friendly regulatory environment.
Dutch VAT rate: 21% standard, 9% reduced (food, medicines, books).
Sweden, Denmark, and Nordic Markets
Nordic consumers are among the world's highest e-commerce spenders. Strong demand for quality goods. High trust in online transactions.
The catch: VAT rates are among the highest in Europe (Sweden 25%, Denmark 25%, Finland 24%). Including VAT in your displayed prices makes Nordic prices appear high compared to the GBP price, which can create price perception issues.
Strategy: Price Nordic markets with EUR pricing (rather than SEK/DKK/NOK) to maintain consistency across EU markets. Most Nordic consumers are comfortable transacting in EUR.
Configuring Shopify for Post-Brexit EU Selling
Set Up EU Markets in Shopify Markets
Configure each major EU country (or group) as a distinct market in Shopify:
Admin → Settings → Markets → Add Market
For each EU market:
- Set currency (EUR for most EU countries; note that Sweden, Denmark, Czech Republic, Hungary, Poland have their own currencies)
- Configure the correct VAT rate for that country
- Enable duties and import taxes
- Set shipping rates and delivery estimates
Enable Duties and Import Taxes
Shopify's Duties and Import Taxes feature (available on Shopify and Advanced plans) calculates estimated import duties at checkout based on:
- The product's HS code
- The customer's country
- The product's declared origin
DDP significantly improves EU conversion rates and customer satisfaction compared to Delivered at Place (DAP) where the customer pays duties on delivery.
To enable: Shopify Admin → Settings → Markets → [EU Market] → Duties and Import Taxes → Enable.
Configure VAT per EU Country
In Shopify Markets, set the correct VAT rate for each EU country. Shopify applies the rate dynamically based on the customer's shipping address — a French customer pays 20% French VAT, a German customer pays 19% German VAT.
If you have IOSS registration, enter your IOSS number in Shopify's international tax settings. This ensures your IOSS number appears on customs documentation for below-€150 parcels, signalling to EU customs that VAT has been collected at checkout.
Shipping Carriers with EU Customs Support
Post-Brexit EU shipping requires carriers with strong EU customs clearance capability:
DHL Express: Industry-leading EU customs handling. Electronic pre-clearance means most parcels clear EU customs before the physical shipment arrives. Strong for time-sensitive and higher-value shipments.
DPD: Strong EU network with pre-clearance capability. Good tracking. Competitive pricing for standard 1–10kg parcels.
FedEx International: Reliable EU customs handling. Strong for heavier shipments.
Royal Mail International: Acceptable for lower-value parcels (under £100) with customers comfortable with 5–10 business day delivery. EU customs clearance is less controlled than express carriers — more variable.
Carrier selection by order value:
- Under £30 product value: Royal Mail International Tracked (cost-effective, acceptable delivery times for low-value goods)
- £30–£100 product value: DPD or Royal Mail depending on delivery time requirements
- Above £100 product value: DHL Express or FedEx — faster delivery and better tracking justifies the cost
Managing EU Returns Post-Brexit
Returns from EU customers create an additional customs complexity layer that did not exist before Brexit.
When a parcel is returned from the EU to the UK, it is a UK import — subject to UK import VAT. If the goods are being returned because they are defective or incorrect, UK import VAT can be reclaimed through your VAT return. But the paperwork requirement adds friction.
Practical strategies for post-Brexit EU returns:
For orders under £50: Consider a "keep it and we'll refund" policy for defective items. The cost of UK import VAT reclaim paperwork plus return shipping logistics often exceeds the product value.
EU returns hub: Partner with a 3PL in the Netherlands, Germany, or Ireland who accepts EU returns on your behalf. Returns arrive locally, avoiding re-importation into the UK. The 3PL holds the goods and either re-ships to new EU customers or periodically consolidates for bulk return to the UK. Significantly reduces per-return cost.
Longer return windows: Offering 30–60 day returns reduces total return volume. Customers who have time to reconsider often keep items they would have returned under a 14-day window.
Clear return instructions in the customer's language: German returns processes differ from French ones. A help page in German explaining how to return from Germany, what paperwork is needed, and expected refund timing reduces return disputes significantly.
Common Post-Brexit Compliance Mistakes
Not registering for IOSS and wondering why EU customers are complaining. If parcels below €150 arrive at EU customs without an IOSS number, every parcel potentially holds and charges the customer. Register for IOSS.
Using British English in EU product descriptions. While not a legal requirement for e-commerce, product pages localised into French, German, Italian, and Spanish convert significantly better. Consider translation for your top-selling products in major EU markets.
Assuming zero tariffs apply when products are Chinese-made. Products sourced from China, India, or other non-UK/EU countries are not UK origin under the TCA and may face EU import duties. Check your specific products.
Providing vague goods descriptions on customs documents. "Clothing" is not an acceptable description. "Women's cotton blouse, navy, size 12" is. Vague descriptions cause customs delays and may trigger inspection.
Not having a UK EORI number. Required for commercial exports. Free and quick to obtain — no reason not to have one before your first commercial EU shipment.
Not registering for German EPR if selling packaged goods to Germany. This is a common oversight that results in marketplace suspension and potential legal enforcement action. Register with LUCID before selling to German customers.
Entering incorrect HS codes. Using a guess or a similar product's code creates liability if customs authorities assess the correct rate and find under-collection. Spend time getting HS codes right for your product range.
How Integrated Business Management Supports Post-Brexit Compliance
Post-Brexit EU selling creates multi-currency, multi-tax jurisdiction complexity that basic accounting software handles poorly. A UK seller with EU B2C and B2B sales manages:
- GBP revenue from UK sales
- EUR revenue from EU sales (at varying exchange rates)
- EU VAT collected in multiple rates, remitted via OSS quarterly
- IOSS VAT collected monthly
- UK VAT on domestic sales
- Exchange gains and losses on EUR receipts vs GBP reporting
[AHAD Global Ventures](/services) builds integrated business management solutions for UK-based businesses operating across the UK and EU, with multi-currency accounting (GBP and EUR in one system), exchange gain/loss tracking, and proper separation of UK and EU VAT obligations.

Frequently Asked Questions
Do I need to register for EU VAT if I only occasionally sell to EU customers? If your total B2C sales to EU customers are below €10,000 per year across all EU countries combined, you are below the OSS threshold. Below this threshold, you can apply UK VAT to EU sales (your UK VAT registration applies). Once you exceed €10,000, register for EU OSS.
What is the difference between IOSS and OSS? IOSS is specifically for imports of goods with a declared value below €150 from outside the EU — it allows pre-collection of EU VAT at checkout so parcels clear customs without additional charges. OSS is for all B2C sales above €150, or sellers who prefer not to use IOSS, where VAT is accounted for in a quarterly return. Many EU sellers use both: IOSS for orders below €150 and OSS for higher-value orders.
Will my products face EU import duties? Only goods with genuine UK origin under the TCA Rules of Origin qualify for zero tariffs. Goods manufactured in China, India, or other third countries and shipped from the UK are not UK origin — they face EU import duties at standard MFN rates. Check the HS code for your products and the applicable EU duty rate.
How do I get an IOSS registration as a UK business? You cannot register for IOSS directly as a non-EU business — you need an EU-established intermediary. An IOSS intermediary is typically a tax or accounting firm established in an EU member state that acts as your EU representative for IOSS purposes. The intermediary registers for IOSS in their name on your behalf. Costs vary from €50/month for simple setups to several hundred for complex operations.
What happens if I get the HS code wrong on my customs documents? EU customs authorities can query incorrect HS codes, resulting in delays. If the incorrect code resulted in under-declaration of duties, customs can assess additional duties plus interest and potential penalties. For systematic errors across many shipments, the exposure can be significant. Get HS codes right from the start — use the UK Trade Tariff tool.
I sold to EU customers before Brexit without any special setup. What do I need now? Your pre-Brexit setup is entirely obsolete for EU sales. You need: a UK EORI number, OSS registration (if above €10,000 EU B2C annual sales), IOSS registration (recommended for below-€150 parcels), commercial invoices with HS codes and origin declarations, and Shopify configured with EU VAT rates. If you are already selling to EU customers without these, review your compliance position urgently.
Conclusion
Five years after Brexit, UK-to-EU selling is not frictionless — but it is absolutely manageable for sellers who understand the rules and build their operations around them. The EU remains a 450 million-consumer market with high purchasing power and strong demand for many British product categories.
The sellers thriving in the EU market in 2026 have done the work: IOSS registration so EU parcels clear customs smoothly, OSS registration for compliant EU VAT accounting, correct HS codes on all customs documentation, and Shopify configured with EU country-specific VAT rates and duties collection.
The sellers struggling are those who either abandoned the EU market in 2021 without exploring the new compliance requirements, or are still shipping without IOSS and generating constant customer service complaints about customs charges.
The compliance burden is real but one-time in nature. Set up IOSS and OSS correctly, configure your systems properly, and ongoing EU selling is manageable with the same effort it always required — minus the assumption that parcels flow freely. Build the compliance infrastructure once and then focus on what drives EU growth: great products, localised marketing, and customer service in European languages.
