UK retailers selling online to EU consumers face new customs costs and data requirements as the bloc reforms its treatment of low-value imports, adding complexity to post-Brexit cross-border trade ahead of the Golden Quarter.
EU targets low-value imports
UK retailers selling goods directly to EU consumers face a new customs cost following the introduction of a temporary €3 duty on low-value imports.
The EU measure took effect on 1 July 2026 and applies to qualifying goods in consignments worth up to €150 imported from outside the EU. It replaces the previous customs duty exemption for low-value consignments and is scheduled to remain in place until 1 July 2028.
The duty is charged at €3 for each tariff category represented in a consignment, rather than per parcel or physical unit. For example, five T-shirts in the same tariff category would attract a €3 duty, while a T-shirt and a watch could attract €6 because they fall into different categories.
The reform is not aimed specifically at the UK. It applies to low-value imports from non-EU countries regardless of their country of origin.
However, it has particular relevance for British retailers because businesses dispatching goods from Great Britain now sell into the EU from outside its customs territory following Brexit.
Why Brexit matters
The EU-UK Trade and Cooperation Agreement (TCA) provides for zero tariffs and zero quotas on qualifying goods, but retailers must meet the relevant rules of origin to benefit from preferential treatment.
This makes the post-Brexit trading relationship more complex than simply shipping goods from Great Britain into the EU.
Retailers seeking preferential treatment need to establish whether their products meet the relevant origin requirements and retain the evidence needed to support their claims. Goods that do not qualify can be subject to the EU's applicable standard tariffs.
The new low-value import regime adds another consideration for retailers selling directly to EU consumers. The treatment of individual consignments can depend on their customs and VAT arrangements, the goods being shipped and whether preferential trade provisions apply.
Responsibility for the temporary duty generally falls on the customs declarant — such as the seller, importer or representative — rather than directly on the consumer, depending on the trading and logistics arrangement.
More product data required
The customs changes extend beyond the new duty.
Product Identifiers (PIDs) can be declared voluntarily from 1 July 2026 and will become mandatory from 1 November 2026 for relevant distance sales of imported goods.
The identifiers are intended to improve product traceability and help customs authorities identify unsafe or non-compliant goods entering the EU market.
For retailers, this creates an additional data requirement at a time when many businesses are already managing more complex customs processes following the UK's departure from the EU.
Accurate product classification and product information will become increasingly important as retailers prepare their e-commerce, fulfilment and customs systems for the new requirements.
Rules of origin remain a separate consideration for businesses seeking preferential tariff treatment under the TCA.
Pressure on low-value sales
The scale of the EU's low-value e-commerce market helps explain why the bloc is changing the rules.
Almost 5.9 billion low-value items were shipped directly from third countries to EU consumers in 2025, according to the European Commission.
The EU says the reforms are intended to respond to rapidly growing e-commerce volumes, strengthen customs controls and create fairer competitive conditions for businesses operating in the European market.
For UK retailers, the commercial impact will vary according to product mix, order value, tariff classification and the way each business manages its customs arrangements.
Retailers selling large volumes of relatively inexpensive products could face particular pressure if additional duties and compliance costs reduce margins or require changes to pricing and fulfilment.
Mixed baskets can also have different cost implications because the €3 duty is determined by the number of tariff categories represented in the consignment rather than simply the number of parcels dispatched.
This makes product classification, basket composition and fulfilment strategy increasingly important considerations for retailers with substantial EU online sales.
A wider customs overhaul
The €3 duty is part of a broader reform of the EU customs system rather than a standalone measure.
The temporary arrangement is scheduled to run until 1 July 2028, when the EU Customs Data Hub for e-commerce is expected to become operational and normal customs tariffs based on the type of goods are due to replace the interim duty.
The wider reform also includes an EU-wide handling fee for small consignments sold through distance selling.
The fee is separate from the €3 customs duty and is intended to contribute to the cost of processing and monitoring the growing volume of e-commerce imports. Its level is to be determined separately, with implementation expected later in 2026.
The reforms therefore represent a sequence of changes rather than a single new cost.
For retailers, the immediate priorities are understanding how the €3 regime applies to their shipments and preparing product data for the mandatory PID requirement from 1 November. Longer term, businesses will need to adapt to the EU's increasingly digital customs infrastructure.
Golden Quarter test
The timing adds pressure for UK retailers preparing for the Golden Quarter, traditionally the most important trading period of the year.
The mandatory PID requirement takes effect on 1 November, shortly before Black Friday and the peak Christmas shopping period.
Businesses selling to EU consumers therefore have a limited window to assess whether their product data, tariff classifications, customs arrangements and fulfilment processes are ready before seasonal order volumes accelerate.
The commercial implications will vary. Some retailers may choose to absorb additional customs costs, putting pressure on margins, while others may pass them on to customers or reconsider pricing and fulfilment arrangements.
For businesses with significant EU sales, the changes could also prompt a review of whether orders should continue to be fulfilled individually from Great Britain or whether holding inventory within the EU could offer a more efficient model.
Brexit did not create the EU's €3 duty, which forms part of a wider overhaul of low-value imports from outside the bloc. But Britain's position outside the EU customs territory means retailers dispatching goods from Great Britain must now navigate those reforms as third-country sellers.
With the €3 regime already in force and mandatory product identifiers arriving in November, the immediate challenge for retailers is operational: ensuring that product data, customs processes and fulfilment models are ready for Europe's changing e-commerce border.
