UK e-commerce sellers shipping to the EU face customs declarations, EU VAT collection, and consumer protection rules different from the UK. For low-value goods under €150 the IOSS scheme simplifies VAT collection. For higher values, either bill DDP (delivery duty paid) and collect EU VAT at checkout or accept that customer experience will suffer.

Brexit changed UK to EU e-commerce from "as easy as domestic" to "as hard as international". The friction is real. Sellers who plan around it can still serve EU customers. Sellers who treat EU as just another domestic market hit problems fast.

What changed in 2021

Pre-2021, UK to EU sales were essentially domestic within the single market. No customs, no separate VAT, fast delivery. Distance-selling rules applied at scale but most SMEs ignored them.

After January 2021:

Every parcel needs a customs declaration.
UK VAT does not apply to EU sales. EU VAT applies at the destination.
Goods may be held at the border for inspection, duty payment, or paperwork issues.
Returns are more complex because the goods are crossing the border twice.

Some categories (food, plants, certain regulated goods) face additional rules from Sanitary and Phytosanitary requirements.

IOSS for low-value goods

The Import One-Stop Shop (IOSS) is the EU scheme designed to handle VAT on low-value e-commerce imports.

How it works:

Applies to goods under €150 per consignment, sold to EU consumers.
You charge EU VAT at the destination country's rate at point of sale (e.g. 19% for Germany, 21% for Netherlands, 23% for Ireland).
You file a single monthly IOSS return through one EU member state of choice.
The goods clear customs without VAT being collected at the border, because it has already been paid.

To register for IOSS, a UK seller typically needs an EU intermediary. Most UK sellers use an IOSS facilitator service (Taxually, Hellotax, AVASK, or marketplace-provided IOSS). Cost typically £30-£200 per month.

IOSS is the right answer for UK e-commerce sellers shipping small parcels to multiple EU countries.

Above €150: separate paths

For consignments above €150:

IOSS does not apply.
Standard EU import VAT applies at the border.
The buyer typically pays VAT (and any customs duty if applicable) before delivery.
The carrier collects on behalf of the customs authority and charges a handling fee (typically €10-€30).

This kills consumer conversion. UK sellers find that EU customers receiving a "pay €40 plus €15 handling before delivery" notice frequently refuse the parcel.

Two ways to avoid this:

Bill DDP (Delivered Duty Paid). You collect all EU VAT and any duty at checkout. You pre-clear with the carrier so the parcel arrives without consumer paperwork. The customer pays once.

DDP needs proper integration: a customs broker, EU VAT registration in destination countries (or use of the EU's One Stop Shop), and a shipping setup that supports DDP labelling. Royal Mail, DHL Express, FedEx, and DPD all support DDP for UK to EU.

Sell only what fits within €150. Many UK e-commerce businesses have effectively capped their EU pricing at €150 per parcel rather than deal with the complications.

Customs paperwork

Every parcel needs:

HS code: a tariff classification for the product. Get it wrong and customs may hold or duty-incorrectly. The 6-digit HS code is the international part; the EU adds 2 more digits for some categories.
Description: must be specific. "Goods" is rejected. "Cotton T-shirt, women's, size M" is accepted.
Value: in GBP and EUR.
Country of origin: where the product was manufactured. Affects duty rates and trade-agreement preferences.
Sender and recipient details.

For UK to EU shipments under specific trade-agreement preferences, you may need a statement on origin to claim zero duty. Goods substantially manufactured in the UK qualify for the UK-EU Trade and Cooperation Agreement's preferential origin rules. The paperwork to claim it is real, but the duty saving on most goods is real too.

Returns from the EU

A UK consumer's right of return triggers a return shipment. The goods cross the border in the opposite direction.

The mechanics:

The consumer ships back at their cost (unless you offer free returns).
Customs at the UK border may charge import VAT again on the returned goods.
You can reclaim this via the "Returned Goods Relief" if the conditions are met.

Most UK sellers absorbing returns include the customs friction in their pricing. Some operate small EU warehouses to handle EU returns without re-crossing the border.

Consumer protection rules in EU

UK consumer protection law does not apply to EU consumers. The destination country's rules do.

Key differences:

EU consumers generally have the same 14-day cooling-off right as UK consumers under the EU Consumer Rights Directive. Most member states implement it identically to the UK rules.
The right to repair, replace, or refund for faulty goods is similar across EU but varies in detail.
Some countries (Germany, France, Italy) have stronger consumer enforcement than others.

For UK sellers, this means your EU returns process should mirror your UK process at minimum. Building country-specific exceptions is rarely worth it.

When EU expansion makes sense

A common pattern for growing UK brands:

Year 1: UK-only.
Year 2: Test EU via IOSS for low-value items. Accept higher CAC and lower conversion.
Year 3 (if EU is over 15% of revenue): consider DDP, an EU fulfilment partner, and local-language stores.

Skipping EU entirely is a valid choice for many UK SMEs. The friction is real and the customer experience compromise is meaningful. Sellers who hit £100K+ EU revenue typically invest in proper EU infrastructure. Below that, the friction may not be worth it.

Bottom line

For UK e-commerce under £500,000 revenue, IOSS for goods under €150 is the right starting point. Pause EU expansion above €150 until you have the volume to justify proper DDP infrastructure. Treat EU as a separate market with its own economics, not just another postcode.
