UK to EU E-commerce: Basics & Pro Tips for 2026

When the UK left the EU, the game changed for anyone shipping parcels across that border.

On 1 July 2026, it changed again. The EU scrapped its €150 duty-free threshold entirely. If you’ve been quietly assuming “it’s a low-value parcel, so there’s no duty,” that assumption stopped being true this summer.

This guide covers the basics every UK seller shipping to EU consumers needs to know, and what’s actually different since the original version of this guide, not just what’s the same with a new date on it.

The basic customs principle hasn’t changed

Leaving the EU single market means parcels crossing into the EU cross a customs border. Wherever a customs border exists, goods get checked, both at the country of export and the country of import. And a customs border means potential VAT and Duty liabilities, for either the buyer or the seller depending on how the shipment is set up.

That principle is unchanged since 2021. What’s changed is how much duty applies, and to how much of your volume.

INCOTERMS: the two that actually matter for B2C parcels

INCOTERMS are the international rulebook for who’s responsible for what in a shipment, published by the International Chamber of Commerce. For B2C e-commerce parcels, you really only need to know two.

DAP (Delivered at Place), or DDU (Delivery Duty Unpaid) as most people still call it out of habit. The shipper accepts no liability for import fees, VAT, or Duty. Those costs land on the recipient. In practice, the parcel arrives in-country, sits at a holding location, and the customer gets contacted to pay before it’s released. If they don’t pay, whether they refuse, can’t be reached, or just never get around to it, the parcel drifts into the returns flow and eventually makes its way back to your warehouse as undeliverable.

DDP (Delivered Duty Paid) means you, the shipper, accept the liability for taxes and fees at the border. The parcel moves without friction. From the customer’s side, DDP is always the better experience, and after 1 July 2026 that gap has widened, not narrowed. See why below.

So what does DAP actually cost you now?

Here’s the consequence of the July 2026 change that a lot of sellers haven’t clocked yet.

Before, if your parcel was under €150, VAT might still apply via IOSS, but duty genuinely didn’t. Now, duty applies to every in-scope parcel regardless of value, via the new flat-rate charge covered below. That means DAP shipments now carry a duty surprise on top of the VAT surprise they already carried. Two unexpected charges instead of one, landing on a customer who already checked out expecting the price they saw.

If you ship DAP without making that liability crystal clear at checkout, expect more refused parcels, more “where is my order” contacts, and more bad reviews from EU shoppers who feel ambushed. This was already true in 2024. It’s materially worse now.

Customs declarations and data requirements

Parcels used to cross borders on simple paperwork: a commercial invoice, or a CN22/CN23 declaration form filled in by hand. That system worked for decades because it wasn’t built for e-commerce volumes, and it was trivially easy to abuse. Under-declaring value to dodge tax liability was common.

To close that gap, cross-border parcel shipping was digitised. Sending B2C goods from one country to another now requires EDI data (Electronic Data Interchange) transmitted through your carrier or postal service, declaring at minimum:

• What’s in the parcel
• The commercial value of the goods
• Who sent it
• Who’s receiving it
• Where the goods originated
• Who’s liable for any import VAT and Duty

None of this applied when shipping UK to EU before Brexit, because the UK was inside the single market. It’s fully required now, in both directions.

HS codes and country of origin: more important than ever

HS (Harmonised System) codes are the standardised numerical codes customs authorities use worldwide to classify goods and apply the correct tariffs. They matter for two reasons: they determine the duty rate, and they’re not language-specific, so they’re the common format customs systems everywhere actually understand.

Here’s why this now matters more directly to your bottom line than it did in 2024: the new flat-rate customs duty introduced in July 2026 is charged per tariff heading, not per parcel. A single parcel containing items from three different HS headings gets charged three times, not once. Get your HS classification right, and you know exactly what a multi-item parcel costs to land. Get it wrong, and you’re either overpaying or building up a compliance liability that catches up with you later.

Country of origin matters for the same reason it always did: it determines which trade rules and preferences apply. If your goods qualify under a free trade agreement, origin can mean the difference between paying a tariff and not.

What about the “Brexit deal”?

The Withdrawal Agreement, in force since 11pm GMT on 31 January 2020, only benefits goods wholly manufactured in the UK or EU from materials sourced there. Unless your products are genuinely, provably UK or EU origin, it does little for you as an e-commerce shipper. That hasn’t changed.

What has happened since is the UK-EU “reset” deal, agreed in 2025 with the SPS (sanitary and phytosanitary) agreement moving into force through 2025 and 2026. It reduces friction specifically for animal and plant products and food safety rules; fewer certificates, fewer inspections. If you sell food, drink, or agricultural products into the EU, it’s worth understanding. If you don’t, it changes nothing about your general customs, VAT, or duty position. Don’t mistake the reset headlines for a rollback of general customs requirements. It isn’t one.

EU import VAT: still a member-state decision

VAT and Duty are controlled separately in the EU. Duty is set at EU level and applies uniformly. VAT is a national tax, so individual member states set their own rate within an EU-agreed framework, which is why the rate you charge varies depending on where your customer is. Rates across the EU still range roughly from the high teens to the high twenties as a percentage, and they do shift occasionally, so check the European Commission’s own VAT database for the current rate in any specific country before you rely on a number from a blog post, including this one.

EU import duty: the part that actually changed

This is the section that made the 2024 version of this guide out of date.

From 1 July 2026, the EU’s €150 duty-free threshold no longer exists. In its place, a temporary flat-rate customs duty of €3 per item category (per four-digit HS tariff heading) applies to low-value B2C consignments up to €150. That flat rate stays in place until the EU’s Customs Data Hub goes live, targeted for mid-2028, at which point full classification-based duty rates apply to everything, regardless of value.

Two things worth being precise about:

• The €3 charge is per tariff heading in the parcel, not per parcel. Three different product categories in one box means three separate €3 charges.
• This is a duty, not a VAT replacement. VAT still applies from the first euro of value, calculated on the goods plus duty where applicable, exactly as before.

If you want the exact duty rate for a specific product beyond the flat-rate period, or for goods outside the low-value bracket, the European Commission’s TARIC database is still the source to check, not the HMRC equivalent. The UK and EU databases diverge, and if EU expansion is genuinely your goal, checking the EU’s own rules matters more than checking the UK’s.

IOSS: what it does, and what it’s never done

IOSS (Import One Stop Shop) lets overseas sellers shipping goods valued at €150 or below hold a single EU-wide VAT registration, collect the correct VAT at checkout, and remit it through one simplified return instead of registering in every member state separately.

Here’s the myth worth killing directly: IOSS registration does not exempt you from the new €3 customs duty. It never covered duty, only VAT, and that hasn’t changed. Plenty of sellers assumed being IOSS-registered meant they were covered for the July 2026 change. They weren’t. IOSS handles VAT. The new flat-rate duty is a separate, additional charge on top.

To register for IOSS you need a VAT intermediary. Established options include Simply VAT, Avalara, SOVOS, and crossbordervat.com, among others; shop around, since service level and cost vary more than the underlying compliance does.

Pro tips for 2026

• Get proper cross-border tax advice, and stay current. The rules changed materially in July 2026 and will change again before the Customs Data Hub lands in 2028. If something sounds too easy, it probably is, and it’s probably storing up a liability for later.
• Register for IOSS, but don’t stop there. If you sell through marketplaces (Amazon, eBay, Etsy), check whether they’re using their own IOSS registration for the sale. If the marketplace made the sale to the EU consumer, the VAT liability sits with them, not you. Either way, IOSS alone no longer covers your full compliance picture; you also need a plan for the new duty.
• Get your HS codes right at the 10-digit level, with accurate country-of-origin data. Since the new duty is charged per tariff heading, sloppy classification now has a direct, multiplying cost, not just a compliance risk.
• Treat DAP/DDU as a false economy unless you’re shipping genuinely low-value goods and you’re upfront about it at checkout. The parcel-level cost of DDP was already worth it for most brands before July 2026. Post-reform, with a duty surprise now stacked on top of the VAT one, the maths tips even further toward DDP.
• Review your carrier options properly. Rates and services have moved on since the immediate post-Brexit turmoil, and again since July 2026. Some carriers now handle the new duty collection automatically as part of a DDP service; others have simply passed the compliance burden straight to you. Know which one you’re dealing with.
• Consider holding stock in the EU, for the businesses it suits. This isn’t right for everyone, but for brands with real EU volume, importing in bulk means the customs event happens once, on the inbound shipment, instead of on every single outbound parcel. Post-July 2026, with per-parcel duty now a reality even on low-value goods, that maths has shifted further in favour of EU-based stock for higher-volume sellers. If you want the fuller decision framework for whether that’s right for your business yet, we’ve covered that separately.

Where this leaves you

BREXIT happened. The rules got more complex in 2021, and they got more complex again in July 2026. Neither of those things has stopped EU-focused UK e-commerce brands from thriving. There are still hundreds of millions of consumers reachable from the UK in a few days by road, and the opportunity hasn’t shrunk, just the margin for getting the operational basics wrong.

If your EU strategy was built before July 2026, it’s worth a proper review, not a guess. SHIPMAX vets 3PL partners across the UK and EU who handle DDP, IOSS, and the new duty requirements as a matter of course, not as a bolt-on. We don’t charge brands for the introduction; our partner network funds us, so our job is finding the fit that actually works for your volume and margin, not steering you toward whoever pays us most.
