Great Britain: collapse of trade with the European Union
Great Britain: collapse of trade with the European Union
When the UK left the EU single market on 1 January 2021, the immediate impact on trade was dramatic and well-documented. Five years on, the picture is considerably more nuanced. UK-EU trade has adapted — though not without permanent structural changes, significant new costs and ongoing friction in specific sectors. And in 2026, a further layer of complexity has been added through EU customs reform that affects all UK-to-EU e-commerce shipments. This blog covers what happened, what changed, and what it means for businesses and shoppers shipping between the UK and EU today.
What the 2021 Data Showed
The UK's Office for National Statistics (ONS) published its first post-Brexit trade data in March 2021, covering January 2021. The figures were stark. Total exports of goods fell by £5.3 billion (19.3%) compared to December 2020 — driven primarily by a £5.6 billion (40.7%) fall in exports to EU countries, the largest single-month drop in UK exports to the EU in over a decade. Total imports fell by £8.9 billion (21.6%), with EU imports down £6.6 billion (28.8%).
The causes were multiple and overlapping: new border documentation requirements under the EU-UK Trade and Cooperation Agreement (TCA), stockpiling in December 2020 ahead of the transition period end, COVID-19 national lockdowns across the UK and major EU trading partners, and the discovery of a new SARS-CoV-2 variant that disrupted cross-Channel logistics in December 2020. Disentangling Brexit-specific effects from pandemic-related disruption was — and remains — a methodological challenge.
Particularly affected sectors included food and live animals (seafood and fish exports to the EU fell by 63.6%), chemicals and pharmaceuticals, machinery and transport equipment, and clothing imports. Non-tariff barriers — particularly the EU's veterinary and phytosanitary controls on UK food exports — introduced friction that had not existed under single market membership.
What Actually Happened — 2021 to 2025
UK-EU trade volumes did recover from the January 2021 shock — partially. As businesses adapted to new documentation requirements, built customs expertise and adjusted supply chains, freight volumes between the UK and EU largely stabilised. However, several structural changes proved more permanent than the initial "teething problems" framing suggested.
Services trade held up better than goods trade. UK financial and professional services continued to serve EU clients under various equivalence arrangements and bilateral agreements, though some activity relocated to Dublin, Frankfurt and Amsterdam. The goods trade — particularly food, agriculture and time-sensitive products — experienced more lasting friction.
UK businesses diversified export markets. The initial disruption to EU exports accelerated an existing trend toward non-EU markets — particularly under the UK's new trade agreements with Australia, New Zealand, Japan, Singapore and the CPTPP bloc. The UK-Australia Free Trade Agreement entered into force in January 2023 and the UK-New Zealand FTA in February 2024, both providing preferential duty rates on qualifying UK goods.
E-commerce was disproportionately affected. The removal of the EU's €22 VAT exemption for imports in July 2021 — and the introduction of IOSS (Import One Stop Shop) — changed the economics of low-value UK-to-EU e-commerce. Sellers now need to register for IOSS or have VAT collected at the border, adding cost and complexity to what had previously been frictionless trade.
UK-EU relations stabilised through the Windsor Framework (2023), which resolved the most contentious issues around Northern Ireland's trade status. The UK-EU reset discussions of 2025 further normalised the political relationship, though the fundamental trade architecture of the TCA — with its non-tariff barriers and rules of origin requirements — remained in place.
The 2026 EU Customs Reform — A New Layer for UK-to-EU E-commerce
From 1 July 2026, the European Union introduced a new flat customs duty on low-value parcels entering the EU from non-EU countries — including the UK. The key changes are:
€3 flat duty per HS code line — for parcels valued at €150 or below, a flat customs duty of €3 applies per distinct product category (HS code). A single parcel containing goods from three different product categories incurs €9 in customs duties. This duty applies to all 27 EU member states.
Upfront VAT collection — for shipments to Germany, Denmark and Luxembourg specifically, Send2Hub collects VAT upfront before dispatch. After paying for shipping, customers receive a separate notification with the VAT charge before their parcel is dispatched. See our customs duty estimator for destination-specific charges.
This is a temporary measure — the EU has confirmed the €3 flat duty is in place until 1 July 2028, at which point the full EU customs reform package is expected to enter into force.
For UK sellers and international shoppers forwarding UK purchases to EU destinations, this new duty represents an additional cost that must be factored into landed cost calculations. Use our country guide for EU destination-specific customs information.
UK Trade Agreements — The Non-EU Opportunity
Post-Brexit, the UK has pursued an active free trade agreement agenda with non-EU countries. Key agreements in force as of 2025-2026 include the UK-Australia FTA, UK-New Zealand FTA, UK-Japan CEPA, UK-Singapore FTA and UK membership of the CPTPP (Comprehensive and Progressive Agreement for Trans-Pacific Partnership). These agreements provide reduced or zero customs duty rates on qualifying UK-origin goods shipped to partner countries — directly relevant for businesses shipping via Send2Hub to these destinations.
To benefit from preferential rates under these agreements, goods must genuinely originate in the UK (meeting rules of origin requirements) and the correct documentation must accompany the shipment. Goods sourced outside the UK and forwarded through Send2Hub do not qualify for preferential rates under UK trade agreements.
How Send2Hub Helps Navigate Post-Brexit UK-EU Shipping
For businesses and shoppers shipping from the UK to EU destinations, Send2Hub's automated platform handles the customs documentation requirements that post-Brexit trade demands. Every outbound shipment from our Stoke-on-Trent warehouse is accompanied by complete customs export documentation — item descriptions, declared values and, where provided, harmonised tariff codes.
Parcel consolidation is particularly valuable for UK-to-EU shipping under the new customs regime. Where goods from multiple UK retailers are consolidated into a single outbound shipment, one customs declaration covers the entire consolidated parcel — though the €3-per-HS-code duty applies to each distinct product category within it. Accurate commodity code classification is therefore increasingly important for EU-bound shipments.

Frequently Asked Questions
How has UK-EU trade changed since Brexit?
The UK's exit from the EU single market on 1 January 2021 introduced non-tariff barriers including customs declarations, rules of origin requirements and border controls that did not previously exist. Initial trade volumes fell sharply but partially recovered as businesses adapted. Some sectors — particularly food and agriculture — continue to face more friction than existed pre-Brexit. The UK-EU TCA ensures duty-free access for qualifying goods but does not remove non-tariff barriers.
What is the new EU customs duty on UK parcels from 1 July 2026?
From 1 July 2026, the EU applies a flat customs duty of €3 per product category (HS code line) to all parcels valued at €150 or below entering any EU country from non-EU countries including the UK. This duty is in addition to local VAT, which already applied to all UK-to-EU imports. The measure is temporary — in place until 1 July 2028.
Do UK goods shipped to EU countries pay customs duty?
UK goods that genuinely originate in the UK may benefit from zero or reduced customs duty under the UK-EU TCA, subject to meeting rules of origin requirements. Goods sourced outside the UK and forwarded from the UK are not UK-origin goods and do not qualify for TCA preferential rates. Use the Send2Hub customs duty estimator to check applicable rates for your specific goods and destination.
How does Send2Hub handle UK-to-EU customs documentation?
Send2Hub prepares standard customs export documentation for all outbound shipments, including EU-bound parcels. Providing accurate declared values and item descriptions at checkout gives the most accurate customs documentation. Including the correct HS tariff code for each item significantly improves clearance speed and accuracy of duty calculation at the EU border.
Which UK trade agreements reduce customs duty on UK exports?
The UK has free trade agreements with Australia, New Zealand, Japan, Singapore and the CPTPP bloc, among others. These provide reduced or zero customs duty on qualifying UK-origin goods shipped to partner countries. The UK-EU TCA also provides preferential rates for qualifying UK-origin goods entering EU countries. Rules of origin requirements apply in all cases.
