Brexit has introduced new customs, VAT, shipping and information requirements that affect how UK e-commerce businesses trade with the EU and the rest of the world. Sellers must now treat many international orders as cross-border, which changes operational processes and website content.
This guide explains the main areas to address on your Shopify, WooCommerce or Magento store, with practical steps to update operations, displays and platform settings so you can continue selling without unnecessary delays or compliance issues.
Understanding Post-Brexit Customs Requirements
Since the UK left the EU single market and customs union, goods moving between the UK and EU are now subject to customs declarations. This applies to both sales from the UK to EU customers and imports of stock from EU suppliers. You must determine whether your products require commercial invoices, commodity codes and possibly export declarations.
Practical step: Classify every product with the correct commodity code using the UK Global Tariff tool on GOV.UK. Add these codes to your product records in your e-commerce platform. When fulfilling EU orders, generate a commercial invoice that includes the seller’s EORI number, buyer’s VAT number if applicable, accurate description, value, weight and commodity code. Store templates in your order management system to ensure consistency.
Reasoning: Incorrect or missing documentation causes parcels to be held at borders, leading to refunds, returns and damaged customer trust. Checking every product once and updating your catalogue prevents repeated errors.
VAT Handling for EU and International Sales
VAT rules changed for distance selling to EU consumers and for goods imported into the UK. Businesses may need to register for VAT in other countries or use simplified schemes depending on sales volumes. VAT treatment also differs for low-value consignments.
Practical steps: Review your annual sales value to each EU member state. Register for the Importing VAT Account or One Stop Shop scheme via HMRC if eligible, and configure your platform’s tax settings to apply the correct VAT at checkout for EU destinations. For UK sales of imported goods, ensure VAT is accounted for at the point of import or sale. Display clear VAT-inclusive pricing on product and checkout pages. Always verify current requirements directly on GOV.UK and HMRC guidance, as rules and thresholds change.
Keep separate records for domestic, EU and rest-of-world sales to simplify reporting. Most platforms allow tax rules by country or zone; set these up once and test with sample orders from different locations.
Shipping Adjustments and Carrier Choices
Shipping to the EU now involves longer transit times, higher costs and the need for customs paperwork. Many carriers require additional information at label creation. Returns from EU customers also become more complex and expensive.
Practical steps: Update your shipping zones in Shopify, WooCommerce or Magento to separate EU destinations from domestic ones. Display realistic delivery estimates that account for customs clearance. Integrate with carriers that handle international customs forms electronically. Offer tracked services as standard for EU orders to give customers visibility. Provide a clear returns policy that states who pays for return shipping from overseas and any associated customs charges.
Reasoning: Transparent delivery information reduces abandoned checkouts. Testing carrier APIs with real product weights and destinations ensures the rates shown at checkout match actual costs, protecting margins.
Information Display Requirements on Your Website
UK e-commerce websites must now provide specific information to EU customers about the seller’s identity, customs charges and import VAT liability. Product pages, checkout and footer should reflect these obligations.
Practical steps: Add your full business name, registered address and contact details in the footer and about page. On EU-facing product and checkout pages, include statements such as “Import duties, taxes and charges are not included in the item price or shipping cost and must be paid by the buyer.” Display your EORI number on order confirmation pages and invoices. Update terms and conditions and privacy policy to cover cross-border data transfers and customs responsibilities. Use geo-targeted messaging if your platform supports it, or add a banner for international visitors explaining potential additional costs.
Check the platform’s documentation for automatic translation or country-specific content features to avoid showing irrelevant UK-only information to EU visitors.
Platform-Specific Configuration Changes
Different e-commerce platforms require slightly different setups to handle post-Brexit trading.
On Shopify: Create separate shipping zones for United Kingdom, European Union and Rest of World. Use apps or manual tax overrides for EU VAT. Enable the “I’m shipping to the EU” option where available and generate commercial invoices automatically through the platform or integrated fulfilment apps.
On WooCommerce: Install plugins for EU VAT compliance and customs invoices. Configure tax classes by country group and use shipping plugins that support Incoterms such as DDP or DAP. Test the checkout flow from an EU IP address.
On Magento: Set up multiple websites or store views if you need different pricing or messaging. Use extensions for automated commercial invoice generation and commodity code management. Update currency and tax rules for each sales channel.
Regardless of platform, run test orders to EU addresses regularly and review the generated documents for accuracy. Update your checkout to collect phone numbers for customs forms.
Ongoing Monitoring and Best Practices
Rules around VAT, customs documentation and carrier requirements continue to evolve. Set a quarterly review process to check GOV.UK, HMRC and your platform’s help centre for updates. Maintain accurate stock origin records so you know whether goods are UK-made, EU-sourced or from third countries.
Consider offering EU customers the option to buy from an EU-based fulfilment partner if volumes justify the investment. For smaller operations, focus on clear communication and accurate paperwork. Train staff or yourself on how to complete customs declarations correctly to avoid delays. Monitor carrier performance on EU routes and adjust shipping partners if service levels drop.
Document your processes so new team members can follow the same standards. This reduces errors during busy periods such as sales events.
Using Support Networks
Organisations such as Loomworks in Liversedge, West Yorkshire, offer free desks, a registered address and mentoring to selected early-stage e-commerce founders. Taking advantage of such local resources can help you discuss compliance questions with experienced operators without paying fees or giving away equity.
Frequently asked questions
Do I need to register for VAT in EU countries after Brexit?
It depends on your sales volume to each EU member state and the schemes you use. The One Stop Shop can simplify reporting for many sellers, but thresholds and requirements change. Check current HMRC and GOV.UK guidance before registering anywhere.
What information must I show on product pages for EU customers?
Clearly state that import VAT, customs duties and taxes are the buyer’s responsibility and are not included in the displayed price. Include your business name, address and EORI number on invoices and order confirmations. Accurate product descriptions help customs processing.
How do I update my Shopify store for Brexit customs rules?
Set up new shipping zones, configure tax rules for EU countries, add commodity codes to products and enable automatic commercial invoice generation. Test the entire checkout and order process with EU destination addresses to ensure all required fields and documents are produced correctly.
Will shipping to Europe become more expensive?
Additional carrier fees, customs processing and potential duties usually increase the total cost. Offer realistic delivery windows, transparent pricing at checkout and tracked services. Review your margins on EU sales and consider adjusting product pricing where necessary.
How often should I review my e-commerce compliance after Brexit?
Check for updates at least every three months or when HMRC or your platform announces changes. Maintain a checklist covering VAT schemes, commodity codes, website statements and carrier integration settings to ensure nothing becomes outdated.
