UK retailers face higher EU eCommerce costs from customs

Shopreturns says UK retailers are facing higher cross-border eCommerce costs under the EU's new low-value import customs regime. Returns and fulfilment changes are proving more expensive than the new €3 charge alone.

More than three weeks after the rules took effect, retailers selling into the EU are beginning to assess the wider cost of shipping parcels valued below €150. The charge applies to each tariff category in a business-to-consumer parcel, but logistics specialists say it is only one part of a broader rise in costs linked to customs administration, delivery delays and goods crossing borders more than once.

The pressure is greatest in categories where returns are common, including fashion, footwear, beauty and homeware. Returned items sent back to the UK can trigger another border crossing, extra paperwork and new logistics charges before they are ready for resale, quickly eroding margins.

That is changing how some retailers view returns, long treated as a routine operating cost rather than a strategic issue. In cross-border trade, the latest customs changes appear to have pushed returns management closer to the centre of commercial decision-making.

"Since the new rules came into force, we've spoken with many UK retailers trying to calculate the financial impact of the €3 charge. Most start by multiplying the fee by the number of parcels they ship. In reality, that's only the visible part of the cost. Once you include customs administration, slower delivery times, returns and products crossing the border multiple times, the true impact on margins becomes much greater," said Paweł Zakielarz, Chief Executive Officer of Shopreturns.

Shopreturns' analysis points to a sizeable annual impact for both smaller sellers and larger merchants. A UK retailer handling about 350 EU orders a month across three customs tariff categories could face roughly €38,000 in additional yearly costs if it makes no changes to its operating model.

Those costs can be reduced if retailers change how they package and group products. By redesigning product bundles and cutting the number of tariff categories in each shipment, Shopreturns estimates the same retailer could lower annual costs by around €20,000.

A simple example illustrates the issue. A parcel containing 10 identical T-shirts attracts one customs charge because the goods share a single tariff classification. Adding a mug creates another tariff category and an extra fee.

Operational rethink

That is prompting many UK retailers to revisit decisions that previously sat with logistics teams rather than senior management. Instead of only deciding whether to absorb the extra charge or pass it on to shoppers, some businesses are reviewing the structure of their European supply chains.

Options under consideration include local fulfilment within the EU, returns centres based in the bloc and changes to the mix of goods in a customer's basket. Each is aimed at reducing the number of border crossings and limiting the customs events attached to a single sale.

"The new customs rules didn't create the returns problem - they exposed how expensive it already was. For years, many retailers treated returns simply as an operational expense. Today they're becoming one of the biggest factors determining profitability in cross-border eCommerce," said Zakielarz.

The shift matters because many UK eCommerce businesses built their European operations around direct shipping from Britain after Brexit, often without substantially changing returns processes or inventory placement. The latest customs regime adds another layer of friction to that model, especially for lower-value goods where margins are already tight.

Retailers in sectors with high return rates may feel the effect first, but the broader lesson could spread beyond those categories. When low-value parcels contain products across several tariff classifications, the cumulative cost rises with complexity, making fulfilment design more important to profitability.

Broader change

Industry observers increasingly see the new customs regime as part of a structural change in UK-EU eCommerce rather than a one-off adjustment. As costs rise, competitive strength may depend less on headline shipping prices and more on how efficiently companies manage inventory, product classification and returns across borders.

For boards and senior executives, logistics is moving beyond a back-office fulfilment function. It is becoming a commercial issue tied directly to margin protection, customer experience and the long-term viability of selling into European markets from the UK.

"The most competitive retailers are no longer asking how to avoid paying another €3. They're asking how to reduce the number of times a product crosses the UK-EU border. That's where the biggest savings are. Over the coming months, companies that treat logistics and returns as strategic business functions - not just operational costs - will be in a much stronger position to compete across Europe," said Zakielarz.
