Since Brexit, trade between the European Union and the United Kingdom has become more complex. The border, which used to be a formality, is now a customs barrier where even the smallest error in documentation can lead to costly delays. Goods held at the border mean not only lost time but also tied-up capital and unhappy customers. How can you avoid this scenario? The key is careful preparation. Here are five steps to help your company ensure smooth deliveries between the EU and the UK.

1. Foundations: Complete and Accurate Documentation
This is the absolute basis of any customs clearance. Treat your documents like a passport for your goods—without them, they won’t go anywhere. Always make sure you have:
Tip: Create a checklist of required documents for each shipment and double-check it before dispatch.
2. Classification Matters: Correct HS Codes
The customs tariff code (HS code) is a unique identifier for your product in the global customs system. Duties, taxes (VAT), and potential restrictions or licenses are all determined based on this code.
Why is it important? An incorrect HS code can result in overpaid duties or, worse, allegations of under-declaration, leading to fines and inspection of your goods.
How to find the correct code? Use official tariff systems such as the Polish ISZTAR or the UK Global Tariff. If in doubt, consult a customs agency. Never guess!
3. Proof of Origin: Your Gateway to Zero Tariffs
The Trade and Cooperation Agreement (TCA) between the EU and the UK allows for zero tariffs. However, this does not happen automatically! To benefit from preferential rates, you must prove that the goods originate from the EU or the UK.
How to do this? Usually, by including a statement of origin on the invoice. This standard declaration must include the exporter’s registered number (REX) for EU shipments valued over €6,000.
Remember: The location of the company does not equal the origin of the goods. A product imported from China and stored in Poland does not acquire EU origin.
4. Digital Systems and Border Processes: Stay One Step Ahead
Both the EU and the UK have implemented IT systems to manage border traffic. Knowing these systems is essential to avoid delays.
5. Partnership: Don’t Go It Alone
Customs regulations are complex and constantly changing. Trying to manage the entire process on your own without proper knowledge is a sure way to run into problems.
Trust the experts: Working with an experienced customs agency or logistics operator is an investment that pays off. A professional agent will not only prepare declarations but also advise on process optimization, verify documents, and represent you before customs authorities.
Summary:
Smooth customs clearance at the EU–UK border is not a matter of luck but of careful preparation. Attention to complete documentation, correct goods classification, understanding rules of origin, and collaboration with experts are the pillars of a smooth and predictable supply chain in the post-Brexit reality.
