Post-Brexit Import Rules: What UK Sellers Must Know

How Brexit Changed UK Importing

Brexit fundamentally altered the UK's trading relationship with both the EU and the rest of the world. For importers, this means new customs procedures, different duty rates, changed compliance requirements, and additional paperwork.

Whether you import from the EU or from third countries like China, the post-Brexit landscape has specific implications you need to understand.

Key Changes for UK Importers

1. UK Global Tariff (UKGT)

The UK replaced the EU's Common External Tariff with its own UK Global Tariff. Key differences:

• Many tariffs were simplified or reduced
• Tariffs below 2% were generally eliminated
• The UK removed tariffs on goods it doesn't produce domestically
• Some categories saw increased tariffs

Impact: Your duty rates may have changed. Review every HS code against the current UKGT, not historical EU tariff rates.

2. EU Imports Now Require Customs Declarations

Before Brexit, goods from EU countries entered the UK freely. Now:

• Full customs declarations required on all EU imports
• Import duty may apply (zero under the TCA if rules of origin are met)
• Safety and security declarations needed
• HMRC customs checks at the border

Impact: If you source from EU suppliers, you now face the same customs process as imports from any other country. Budget for customs broker fees and potential delays.

3. Rules of Origin Under the TCA

The UK-EU Trade and Cooperation Agreement provides zero-tariff, zero-quota trade — but only for goods that meet rules of origin requirements:

• Products must be "sufficiently processed" in the UK or EU
• Different rules apply to different product categories
• Documentation (EUR.1 certificate or origin declaration) is required

Important: If your EU supplier sources components from a third country (e.g., China), the finished product may not qualify for zero-tariff treatment. Verify with your supplier.

4. UKCA Marking

The UK Conformity Assessed (UKCA) mark replaced the CE mark for products sold in the UK. However, the UK has extended recognition of CE marking for many product categories.

Current status:

• CE marks remain accepted indefinitely for most products placed on the UK market
• New UKCA marks are required for specific categories
• Northern Ireland follows EU rules (CE marking required)

5. Postponed VAT Accounting (PVA)

One genuinely positive Brexit change: PVA allows importers to account for import VAT on their VAT return rather than paying it at the border. This dramatically improves cash flow for regular importers.

Impact on Costs

For EU Imports

Before Brexit:

• No customs declarations: £0
• No import duty: £0
• No customs broker needed: £0
• Total additional cost: £0

After Brexit:

• Customs declaration: £50–£150 per entry
• Import duty: 0% if rules of origin met, otherwise standard rates
• Customs broker: £50–£150 per entry
• Potential delays: Variable
• Total additional cost per shipment: £100–£300+

For Non-EU Imports

The process for importing from China, India, Vietnam, etc. hasn't changed dramatically. The main differences:

• New UKGT rates (some higher, some lower than previous EU tariff)
• New trade agreements (UK-Japan, UK-Australia, CPTPP) offering preferential rates not available under EU membership
• Different compliance requirements (UKCA vs CE)

Opportunities Created by Brexit

New Trade Agreements

The UK has negotiated trade agreements independently, some offering better terms than EU-era agreements:

• UK-Japan CEPA: Enhanced access compared to EU-Japan EPA
• UK-Australia FTA: Significant tariff reductions
• CPTPP membership: Access to Pacific economies including Vietnam, Malaysia, and Chile
• Developing Countries Trading Scheme: Simplified preferences for developing nations

Simplified Tariff Structure

The UKGT eliminated nuisance tariffs (below 2%) and simplified classification in some areas, reducing costs for certain product categories.

Freeport Zones

The UK established several freeports offering:

• Deferred or reduced customs duty
• Simplified customs procedures
• Business rate relief
• Tax incentives for investment

If you're based near a freeport (East Midlands, Humber, Liverpool, Plymouth, Solent, Teesside, Thames), investigate whether operating through the freeport could reduce your costs.

Practical Steps for Importers

1. Review all HS codes against current UKGT rates
2. Check trade agreements for preferential rates on your products
3. Set up PVA to eliminate upfront VAT payments
4. Budget for customs costs on EU imports you previously received duty-free
5. Update compliance documentation — UKCA marks where required
6. Register for HMRC systems — Customs Declaration Service, Government Gateway
7. Choose a competent customs broker familiar with post-Brexit procedures
8. Review origin documentation for EU goods claiming TCA zero-tariff treatment

Staying Current

Brexit regulations continue to evolve. The UK government regularly adjusts tariffs, trade agreements come into force, and compliance requirements are updated.

Subscribe to HMRC trade alerts and review your import procedures quarterly. Your customs broker should proactively notify you of relevant changes, but ultimately the responsibility for compliance is yours.

The importers who treat post-Brexit changes as an opportunity — leveraging new trade agreements, using PVA, and ensuring accurate classifications — are finding that the new framework, while more complex, can be navigated profitably with the right knowledge and tools.
