Post-Brexit, the United Kingdom operates its own independent customs system separate from the EU. HMRC's Customs Declaration Service (CDS) is the primary platform for all UK import declarations. UK importers now face UK Global Tariff (UKGT) rates, a UK-specific import VAT regime, and new GB-EU border formalities. Northern Ireland operates under the Windsor Framework, maintaining some EU customs alignment. Understanding the post-Brexit import landscape is critical for any business shipping goods into the UK.
UK Customs System — CDS (Customs Declaration Service)
CDS replaced the legacy CHIEF (Customs Handling of Import and Export Freight) system in 2023. All UK import declarations are now filed through CDS:
- EORI (Economic Operator Registration and Identification) number mandatory for all UK importers — apply free at HMRC
- CDS declarations filed by licensed customs agents or directly by importers with CDS access
- Goods Vehicle Movement Service (GVMS) for accompanied road freight at Dover and Channel Tunnel
- Safety and Security declarations (ENS — Entry Summary) required for imports from outside UK
- Pre-lodgement model at some ports: declarations filed before vessel arrival
Key UK Ports and Customs Locations
| Port | Type | Key Goods | Volume |
|---|---|---|---|
| Felixstowe | Sea | Containers from Asia | UK's largest container port (4M TEU) |
| Dover / Channel Tunnel | Sea / Rail | EU road freight | Highest value UK trade route |
| Tilbury (London Gateway) | Sea | Consumer goods, FMCG | Major London gateway |
| Southampton | Sea | Vehicles, containers | UK's largest vehicle import port |
| Heathrow Airport | Air | Electronics, pharma, courier | UK's largest air cargo hub |
| Manchester Airport | Air | General air cargo | Northern England hub |
UK Global Tariff (UKGT) — Duty Rates
| Category | UKGT Rate | Notes |
|---|---|---|
| Most manufactured goods | 0–6.5% | Broadly similar to pre-Brexit EU rates |
| Agricultural goods | Variable (0–80%+) | UK retained agricultural protection post-Brexit |
| Textiles and clothing | 10–12% | UK maintained textile tariff protection |
| Vehicles (cars) | 6.5% | UK-EU TCA: 0% for EU-origin qualifying cars |
| EU-origin goods (UK-EU TCA) | 0% | Must meet UK-EU rules of origin |
| Developing country goods (DCTS) | 0% or reduced | UK Developing Countries Trading Scheme replaces EU GSP |
UK Import VAT and Postponed VAT Accounting (PVA)
Import VAT of 20% (standard) or 5% (reduced) applies on CIF + customs duty. For UK VAT-registered businesses, Postponed VAT Accounting (PVA) is the most important cash flow tool:
- PVA allows import VAT to be accounted on your VAT return instead of paying at border
- Declare import VAT as both output and input tax on same VAT return — net cash impact is zero for most businesses
- Download Monthly Postponed Import VAT Statement from HMRC online account
- Non-VAT-registered importers must pay import VAT at border before release
Northern Ireland — Windsor Framework
Northern Ireland has a unique arrangement under the Windsor Framework (2023):
- Goods moving GB (Great Britain) to NI: subject to UK Internal Market Scheme (UKIMS) — most goods for NI end-use enter without EU customs duty
- Goods moving NI to Republic of Ireland (EU): EU customs rules apply
- Green Lane: trusted traders move GB-NI goods with minimal checks
- Red Lane: goods at risk of entering EU must pay EU customs duty
UK FTA Network Post-Brexit
| Agreement | Partner | Benefit for UK Importers |
|---|---|---|
| UK-EU Trade and Cooperation Agreement | EU27 | 0% duty on qualifying goods |
| UK-Australia FTA | Australia | Staged elimination of tariffs (fully zero by ~2028) |
| UK-Japan CEPA | Japan | 0% on most goods; better than EU-Japan EPA |
| UK-Singapore FTA | Singapore | 0% on most goods |
| CPTPP (UK joined 2023) | 11 Pacific countries | Reduced tariffs across Pacific rim |
| UK-India FTA | India | Under negotiation; not yet in force |

- Decide: use a customs agent or file CDS declarations yourself
- For sea/air: pre-lodge CDS declaration before vessel arrival where possible

- Pay customs duty if applicable (bank transfer or duty deferment account)
- HMRC Border Force releases goods at port upon successful declaration
