UK–EU Trade After Brexit: What It Actually Means for Your Business in 2026
Five years on from the Brexit transition, plenty of UK businesses still run into surprises when they start shipping to Europe. The free trade deal is real — but it doesn’t mean frictionless trade, and it doesn’t eliminate paperwork. This guide explains what UK–EU trade actually looks like today, what the deal covers, and what you still need to do every time you ship.
The UK–EU Trade and Cooperation Agreement: What It Does (and Doesn’t) Do
The UK and EU signed the Trade and Cooperation Agreement (TCA) in December 2020, which came into force on 1 January 2021. The headline headline benefit: goods of UK or EU origin can be traded between the two without import duties — zero tariffs — providing they genuinely originate in the UK or EU.
That’s significant. On many product categories, EU import duty rates for third countries (the rate that would apply without the TCA) run from 3% to 12%, and higher for certain goods. Avoiding that is a real commercial benefit.
But the TCA is not a customs union, and it is not a single market agreement. The UK left both. What that means in practice is:
Every commercial shipment from the UK to an EU country — or from an EU country to the UK — requires a customs declaration at both ends. There are no exceptions for small volumes, long-standing trading relationships, or shipments below a certain weight. The declaration must be filed, duties assessed, and clearance granted before goods can move freely. This applies whether you’re sending one pallet or fifty.
The TCA removed tariffs. It did not remove the customs process. Those are two different things.
What Zero Tariffs Actually Requires: Rules of Origin
This is the part most businesses miss when they first read about the trade deal.
Zero tariffs under the TCA only apply to goods that genuinely originate in the UK or the EU — meaning they were manufactured there, or substantially transformed there. You can’t buy goods from China, ship them to a UK warehouse, and export them to Spain at zero EU import duty by claiming they’re British. The goods have to actually be British.
Proving origin requires a statement of origin on your commercial invoice. For shipments over €6,000 in value, that statement must also include your UK REX number (Registered Exporter number), which you register for through HMRC — it’s free.
Without the statement of origin, your EU customer pays standard MFN (most favoured nation) import duty on arrival, even if your goods qualify for zero tariff. This is one of the most common and most preventable costs in UK–EU trade. It happens because exporters don’t know they need to make the claim — it isn’t automatic.
What counts as “UK origin”?
For wholly manufactured goods — something made entirely from UK materials in a UK factory — this is straightforward. For goods that use imported components or raw materials, the TCA’s product-specific rules of origin apply. These are detailed and vary by product category. In general terms, the goods must have been sufficiently processed in the UK to be classed as UK origin. Your freight forwarder or a customs adviser can help you determine whether your specific products qualify.
What You Need Every Time You Export to the EU
The customs process for UK–EU exports has been stable since 2021. Here’s what’s required for every commercial shipment:
UK EORI number. You must have one to export. Register through HMRC — it’s free and takes a few working days. Your freight forwarder needs this to file your export declaration.
UK customs export declaration. Filed with HMRC’s Customs Declaration Service (CDS) before your goods leave the UK. Your freight forwarder handles this on your behalf, but they need accurate information from you to do it correctly.
Commercial invoice. A specific, accurate description of the goods — not “parts” or “products” but what the items actually are. Plus quantity, unit value, total value, currency, country of origin, and the agreed Incoterm (EXW, DAP, DDP, etc.). This document drives everything else in the process.
Packing list. An itemised breakdown of every package — dimensions, gross weight, net weight, number of pieces. Must be consistent with the commercial invoice.
HS (commodity) code. The 10-digit tariff classification for your goods. This determines whether any export controls apply and feeds directly into the EU import duty calculation.
Statement of origin (if applicable). If your goods are of UK origin and your customer wants to claim preferential zero-tariff rates, this must be on the commercial invoice. For shipments over €6,000, include your REX number.
EU import declaration. Filed by your customer’s customs agent at the destination end with the relevant EU customs authority. This is separate from your UK export declaration and is your customer’s responsibility — though the documents you provide make or break it.
What You Need Every Time You Import from the EU
The same process applies in reverse. Goods coming from the EU into the UK require a UK import declaration filed with HMRC. Import duty is assessed based on the HS code and the customs value of the goods (usually the transaction value plus freight and insurance costs to the UK border).
For EU goods of EU origin, preferential rates may apply under the TCA — but your EU supplier needs to include a valid statement of EU origin on their invoice. If it’s missing, you pay standard UK Global Tariff duty rates.
Postponed VAT Accounting (PVA) is worth knowing about if you import regularly. Instead of paying import VAT at the border and waiting to reclaim it on your next VAT return, PVA lets you account for it on the return directly — better for cash flow, and now standard practice for most UK importers.
The Three Things That Still Catch UK Businesses Out
Five years in, the same issues keep coming up.
1. Vague commercial invoices. The description of goods on the invoice must be specific. “Spare parts,” “equipment,” “merchandise,” or “samples” are not sufficient for customs purposes. Customs authorities on both sides need to know what the goods actually are to classify them correctly, assess duties, and check whether any restrictions or licences apply. Vague descriptions are the single most common cause of customs delays.
2. Missing statements of origin. Businesses entitled to trade at zero tariff under the TCA are routinely paying duty because they don’t include the statement of origin on their invoices. It’s a short addition to a document you’re already creating, and it can save your customer a meaningful amount of money on every shipment.
3. Wrong or missing EORI numbers. Both the UK exporter and the EU importer need valid EORI numbers on the declarations. If either is missing or incorrect, the declaration can’t be processed. Confirm your customer’s EU EORI number before you ship for the first time — it avoids a last-minute scramble.
A Note on Machinery and Industrial Equipment
If you manufacture or supply machinery, capital equipment, or industrial components into the EU, two additional considerations apply.
CE marking. Machinery placed on the EU market must carry CE marking to indicate compliance with EU directives (primarily the EU Machinery Directive). Post-Brexit, the UK has its own UKCA marking for the UK market, which is separate. If you’re exporting machinery to the EU, CE marking is still required. If you’ve been relying on a UKCA-only certification process, this is worth reviewing with your notified body.
Export licensing. Certain categories of goods — dual-use items, some industrial technologies, military goods — require an export licence before they can leave the UK. Check whether your product falls into any controlled category. Your freight forwarder can flag this but the responsibility for compliance sits with you as the exporter.
