Everyone's talking about the new €3 customs duty on EU parcels starting July 2026. Most articles explain what it is. Very few explain who actually hands over the money, and at what point in the transaction. The answer changes everything about how you should prepare.
The short version: your customer pays it. But when they pay it — and how much they end up paying — depends entirely on one decision you make as a seller.
One rule. Two very different outcomes.
The €3 customs duty applies to parcels valued under €150 entering the EU from a non-EU country (including the UK). But the way it's collected depends on whether you're registered for IOSS — the EU's Import One-Stop Shop for VAT.
Most UK sellers selling to EU customers already use IOSS (it covers roughly 93% of cross-border e-commerce flows into the EU). If you're one of them, here's what July 2026 looks like for you and your customer.
Track 1: You use IOSS
The customer pays €3. They just don't feel it, because it happened at the moment they clicked "buy".
This is the clean version. Clean for the customer, clean for your conversion rate, clean for your return rate.
Track 2: You don't use IOSS
The customer is asked to pay €13–18 to receive a €30 item they've already been charged for. At that point, many of them simply say no.
The trap lawyers are talking about
A legal analysis circulating among customs advisors makes an interesting technical observation:
"The €3 flat-rate duty specifically applies to IOSS-registered sellers. Technically, the simplest way to avoid the €3 is to stop using IOSS."
It sounds logical. It isn't.
Without IOSS, your customer doesn't pay €3 at checkout. But they get hit with €13–18 at their front door (€3 duty + €10–15 carrier handling fee for processing the customs declaration). Parcel refusals spike. Returns surge. And from 2028, without IOSS you'd need to register for VAT individually in every EU country you sell to.
Saving €3 per order by dropping IOSS costs you far more in refused deliveries and return logistics.
The real decision you need to make before July 1st
It's not whether to use IOSS. It's how you handle the €3 in your pricing.
You have three options:
1. Absorb it into your margin
You eat the €3. Price stays the same for the customer. Cleaner UX, but margin impact — especially on low-value items. A €20 product with a 30% margin loses a meaningful slice per unit.
2. Pass it on transparently at checkout
Show the €3 as an "EU import duty" line at checkout, like you'd show VAT. Honest, but you need to test how it affects conversion. A surprise €3 at checkout is better than a surprise €13 at the door, but it's still a friction point.
3. Adjust base price for EU customers
Round up EU pricing by €3–4 across the board. Cleaner checkout experience, no separate line item. Works well if your prices already vary by market.
There's no universally right answer. It depends on your average order value, your return rate, and how price-sensitive your EU customers are.
What this means for returns
Here's where it gets expensive — and where most sellers haven't done the maths yet.
Under Track 1 (IOSS), you collect €3 at checkout. If the customer returns the item, that €3 is — in principle — refundable (see our previous post on duty recovery). But "in principle" requires paperwork, timelines, and volume to make it worth pursuing.
Under Track 2 (no IOSS), the customer who did accept the parcel paid €13–18 at the door. When they return it, they want that back. Your refund policy now has a problem: do you refund the carrier handling fee too? Most brands don't, most customers expect it.
Either way, the return gets more expensive after July 2026. The only variable is how you've structured the cost flow going in.
The numbers on a typical fashion order
Take a £35 jumper sold from the UK to a customer in Germany:
The difference isn't just €3. It's the difference between a manageable cost and a broken customer experience that generates returns, disputes, and lost repeat buyers.
The bottom line
The €3 is coming regardless. The question is whether your customer feels it as a small line at checkout, or as a shock at their front door — with a €10 surcharge attached.
For the vast majority of UK sellers with IOSS in place, the practical task before July 1st is simple: decide where the €3 sits in your pricing model, update your checkout accordingly, and make sure your returns policy is set up to handle the new duty recovery mechanics.
The sellers who will feel this most are the ones who do nothing and let the non-IOSS scenario play out by default. That's when €3 becomes a much bigger number.
