Beyond the EU’s €3 customs charge: practical strategies for UK retailers
Should UK retailers move stock and returns into the EU to protect margins?
UK exports are approaching £1tn, but for retailers selling into Europe, protecting margins is becoming increasingly difficult. One month after the EU introduced its new €3 customs duty, the question is no longer just how to absorb another cross-border cost. For retailers operating at scale, it is whether their current model for stock, fulfilment and returns still makes economic sense.
The latest figures from the UK Department for Business and Trade show that British exports continue to grow despite a challenging economic environment. UK exports reached £946.6bn in the 12 months to May 2026, while exports to EU countries totalled £385.3bn in the 12 months to March 2026.
Europe therefore remains one of the most important markets for UK businesses. At the same time, selling from the UK into the EU is becoming increasingly expensive and operationally complex.
The €3 duty is only the beginning
Since 1 July 2026, low-value e-commerce consignments entering the EU have been subject to a temporary €3 customs duty per item category, based on tariff classification. Five identical T-shirts within the same category attract a €3 charge, while three T-shirts and a watch in another category attract €6. For retailers, the immediate response is operational. HS codes need to be accurate. DDP can prevent unexpected charges reaching customers at delivery. Mixed-category bundles need to be reviewed. But businesses selling at greater scale should also look beyond individual parcels and examine how their entire EU operation is structured. That includes two increasingly important questions: should some stock already sit inside the EU, and should products sold to EU customers really cross the UK-EU border again when they are returned?For e-commerce brands and retailers shipping hundreds or thousands of EU orders a month, relatively small costs at parcel level can quickly become significant annual costs.
Why does this need attention now?
The new duty forms part of a broader reform of the EU customs system. Further changes are already scheduled. Product Identifiers (PIDs) are expected to become mandatory on customs declarations from 1 November 2026, while a separate EU handling fee has also been proposed, although its final amount and implementation date are still to be determined. From 1 July 2028, the temporary flat-rate system is expected to end as the EU moves towards its new customs framework. For retailers, this means the €3 duty should not be treated as an isolated cost to absorb and forget. It is another reason to understand the total cost of serving an EU customer, from checkout and customs clearance through delivery, returns and getting returned stock back into circulation.
“Retailers should stop asking what one parcel costs and start asking what one completed EU sale costs. Delivery, duties, failed delivery, returns, inspection and the time a product remains unavailable for resale all belong in the same calculation. Once that number is
visible, decisions about stock, fulfilment and returns become much easier,” says Paweł Zakielarz, CEO of Shopreturns.
Where is the money actually leaking?
The most visible new cost is the €3 duty, but it is not necessarily where retailers stand to lose the most. One issue is mixed baskets containing several tariff categories. Another is a delivery model in which unexpected charges reach the customer at the door, turning a relatively small customs cost into a refused delivery, chargeback or lost customer.
Returns add another layer
A product sent from the UK to a customer in Germany, France or Spain may subsequently have to travel back across the border. During that time, the retailer is paying for transport and handling while the product remains unavailable for resale. This is particularly important for categories such as fashion and footwear, where returns are a routine part of the business model rather than an exception.
“Cross-border returns should be treated as a margin issue, not simply a customer-service process. If a returned product can stay within the EU, it can be inspected quickly and the retailer can decide whether it should be restocked, resold or consolidated for onward transport. The faster that decision is made, the faster saleable stock can get back into circulation,” says CEO Shopreturns.
What does this mean for different retailers?
For smaller cross-border sellers, the answer is likely to be optimisation rather than relocation: accurate customs data, DDP and a simpler local returns process. For fast-growing DTC brands, particularly in fashion and footwear, the calculation becomes more complex. Return rates, refund times and the speed at which returned products can be put back on sale all affect the profitability of an EU order. For larger retailers operating across several EU markets, the question can become structural. At sufficient scale, it may be worth comparing the existing parcel-by-parcel model with moving stock into the EU in bulk and fulfilling customer orders locally.
Should stock move into the EU?
There is no single order volume at which EU fulfilment automatically becomes the better option. The calculation depends on basket composition, gross margin, warehousing and inbound transport costs, destination markets and return rates.
“There is no universal break-even point, but once a retailer is shipping several hundred orders a month to the EU, it should start modelling the alternatives. Take 300 EU orders a month with an average of two tariff categories per parcel. At €3 per category, the new duty alone would represent around €1,800 a month, or €21,600 a year, before other cross-border costs are included. That does not mean order number 301 suddenly makes EU fulfilment more profitable. It means the cost is becoming significant enough that simply treating it as an unavoidable expense no longer makes business sense,” says Paweł Zakielarz, CEO of Shopreturns.
For some retailers, moving stock into the EU in bulk and fulfilling locally may prove more efficient. For others, the economics may still favour shipping outbound orders from the UK.
And there is a middle ground
A retailer does not have to move its entire fulfilment operation to change the economics of returns. It can continue shipping orders from the UK while giving EU customers local return addresses. Returned goods can then be inspected and processed within the EU rather than automatically travelling back across the border one parcel at a time.
For UK retailers, the question is therefore not whether Europe remains worth serving. The size of the market makes that clear. The real question is how many times a product needs to cross the border before a sale is truly complete.
