The evolution of Post-Brexit customs rules in 2025 continues to reshape trade between the United Kingdom and the European Union. Since 1 January 2021, Brexit has fundamentally reshaped the way trade is conducted between the United Kingdom and the European Union. What was once considered intra-EU trade is now subject to international trade regulations, including customs declarations, import duties, VAT, and compliance obligations.
As we move through 2025, new measures are being rolled out, and it’s essential for online sellers in the EU to stay informed to avoid delays, penalties, or even loss of customers.

A Continually Changing Landscape
The first few years after Brexit were marked by uncertainty, but both UK and EU authorities have gradually introduced clearer frameworks. However, this doesn’t mean things have become easier. As of 2025, several developments are worth noting:
- The full implementation of the UK’s Border Target Operating Model (BTOM), which introduces stricter checks on food, plants, and other risk categories.
- New pre-lodgement requirements for imports, particularly through the UK’s Goods Vehicle Movement Service (GVMS).
- Increased customs controls on goods arriving from the EU, especially for B2C (business to consumer) parcels.
Understanding the Post-Brexit customs rules in 2025 is essential for EU e-commerce businesses shipping to the UK.
VAT and Customs: Common Pitfalls
For EU-based e-commerce sellers, these changes carry real implications:
- UK VAT registration is often required, even for relatively small-scale sales.
- Import VAT and customs duties may be passed on to the end customer if the delivery terms (e.g. DDP vs DAP) are not handled correctly.
- Complexity of customs declarations: errors in commodity codes, valuation, or origin can cause serious delays at the border.
How to Adapt Effectively
Here are some key practices to adopt in 2025:
- Use customs automation tools, like those offered by MyDutyCollect, to simplify and streamline declarations.
- Plan for import costs (duties + VAT) and factor them into your pricing strategy.
- Work with a reliable customs broker or freight forwarder, especially if you’re handling high volumes.
- Choose your Incoterms wisely: shipping DDP (Delivered Duty Paid) improves customer experience but puts the compliance burden on the seller.
Barrier or Opportunity?
Despite the red tape, the UK remains a lucrative market: high purchasing power, strong demand for EU products, and a mature e-commerce culture. By mastering the new customs landscape, sellers can turn this challenge into a competitive edge. With the Post-Brexit customs rules in 2025 in full effect, sellers must stay informed about new compliance procedures.
