The UK customs clearance imports process is the official system used to declare goods entering the United Kingdom. All imports must be checked and approved by HM Revenue and Customs before they can be released into the UK market.
Goods arriving through major entry points such as Port of Felixstowe, Port of Southampton, Dover, and Heathrow Airport must pass customs checks under HMRC rules.

Errors in paperwork or classification often cause delays at this stage.

VAT rules for UK imports
Import VAT is calculated using:
- Goods value
- Shipping cost
- Insurance
- Customs duty
Many UK VAT-registered businesses use Postponed VAT Accounting (PVA), which allows VAT to be recorded on returns instead of paid at import.
If VAT is incorrect or missing, goods may be held until resolved.
Customs inspections in the UK
Some shipments are selected for inspection by HMRC or Border Force.
Inspections may include:
- Container opening
- Document checks
- X-ray scanning
- Physical cargo checks
Ports like Felixstowe and Heathrow often experience delays during peak inspection periods.
When issues are found, customs may request corrections or additional documents.
Common causes of customs delays
Delays usually happen due to:
- Incorrect commodity codes
- Missing invoices
- Unpaid VAT or duty
- Late CDS submission
- Port congestion
- Customs inspections
- Incomplete product descriptions
- Missing licenses
Submitting documents early reduces most of these risks.
