One month after the European Union introduced its new €3 customs charge on low-value imports, UK retailers are beginning to understand that the biggest challenge is no longer the fee itself, but how their entire cross-border operation is structured. While the regulation immediately increased the cost of selling into Europe, businesses that review their product catalogue, pricing strategy, fulfilment model and returns process can significantly reduce its financial impact.
The €3 fee is only the beginning
Since 1 July 2026, every consumer parcel entering the EU from the UK has been subject to a €3 customs charge for each HS product category included in the shipment. A parcel containing products from three different tariff categories now costs €9 more than an identical order shipped before the regulation came into force. For retailers shipping hundreds or thousands of orders each month, these costs quickly accumulate into tens or even hundreds of thousands of euros annually. Yet customs specialists argue that focusing exclusively on the €3 fee misses the bigger picture.
“One month after the new rules came into force, we’re already seeing a clear divide. Retailers still treating the €3 charge as a customs issue are looking in the wrong place. The biggest savings won’t come from customs declarations -they’ll come from redesigning fulfilment, product assortment and returns. That’s where margins are now won or lost.” says Paweł Zakielarz, CEO of Shopreturns.
Where should retailers start? It depends on their business model
Rather than applying one universal solution, Shopreturns recommends tailoring the response to the company’s sales model and shipment volume.
Marketplace sellers (fewer than 100 EU orders per month)
Businesses selling through marketplaces such as Amazon, eBay or Etsy should begin by reviewing product classifications and increasing average basket values. Since marketplaces already manage much of the regulatory compliance, improving product listings and order economics often delivers the quickest financial gains.
Retailers selling through their own ecommerce store
Brands selling products from a single product category via their own online store usually face lower customs exposure. For these businesses, validating HS codes and encouraging larger average orders can substantially offset the additional customs costs.
Brands selling gift boxes and mixed-product bundles
Retailers whose business relies on gift sets or mixed-product baskets have some of the greatest optimisation opportunities. Because the €3 charge is applied per HS tariff category rather than per parcel, redesigning product bundles and reducing unnecessary category combinations can immediately lower customs costs.
UK manufacturers selling higher-value goods
Manufacturers whose products genuinely qualify as UK-origin goods under the UK-EU Trade and Cooperation Agreement (TCA) should assess whether preferential origin rules could reduce customs costs. However, any changes should first be reviewed with a customs specialist.
Businesses shipping more than 300 EU orders each month
For larger retailers, the conversation increasingly moves beyond customs optimisation. At this scale, EU-based fulfilment and local returns infrastructure often become commercially attractive because eliminating repeated border crossings can generate savings that outweigh warehouse operating costs.
Fashion and footwear retailers
Brands operating in categories with return rates above 15% should prioritise returns rather than outbound shipping. In many cases, reverse logistics already represents a greater financial burden than the new customs charge itself.
Companies using temporary import procedures or inward processing arrangements may also benefit from specialist customs mechanisms such as ATA Carnets or Inward Processing Relief, although these solutions are designed for specific operational models rather than mainstream ecommerce.
“There’s no universal response to the new customs rules. A marketplace seller shipping 50 parcels a month has completely different priorities than a fashion retailer sending thousands of orders into Europe. The first question shouldn’t be ‘How do we avoid the €3 charge?’ but ‘Which part of our operation is actually generating the cost?’says Paweł Zakielarz.
Returns may become the hidden customs cost
While outbound shipments have dominated industry discussion since July, expert believes returns could become the more expensive side of the equation. Every item returned from the EU to the UK creates another border crossing, additional customs administration and, in many cases, another round of duties if the product is later resold into Europe. For sectors such as fashion, where return rates frequently exceed 15%, reverse logistics can quickly cost more than the original customs charge. Local EU return addresses and fulfilment centres allow products to remain inside the Single Market, reducing border crossings, shortening delivery times and enabling returned items to be inspected, restocked and resold without repeatedly entering the customs process.
Compliance alone will no longer be enough
The customs charge introduced in July represents only the first stage of wider EU customs reform. Additional reporting obligations, including mandatory Product Identifiers (PIDs), will come into force later this year, while the European Commission has already announced increased monitoring of attempts to circumvent the new customs framework.
For retailers selling into Europe, the first month under the new rules has demonstrated that customs compliance is no longer simply a legal obligation-it has become a commercial advantage.
Businesses that review their fulfilment strategy, product assortment and returns operation now are likely to be significantly better positioned before peak trading season than those treating the €3 charge as merely another unavoidable cost.
