Commercial Goods Import Customs Clearance

- Freight forwarders and shipping agents

- Businesses importing through UK ports, airports or road routes


Why this service matters
Missing or inconsistent customs data can delay release, lead to additional port charges and create duty or VAT errors. The correct customs treatment depends on the goods, documentation and the importer's circumstances.
Good preparation helps ensure that the declaration is supported by the right commercial and transport information before the shipment arrives.
How Cartwright CS helps
We review the available shipment paperwork, identify missing information and explain the steps needed for the customs entry. We prepare and submit the agreed UK customs declaration, check the customs outcome and coordinate with the appropriate transport or terminal parties for release.
Where duty relief, preferential origin or a special customs procedure is being considered, we identify the supporting information required for review rather than assuming that relief applies.


Common challenges we solve
- Unclear or incomplete commercial invoices and packing lists
- Missing or unverified commodity codes
- Uncertainty over origin, preference and documentary evidence
- Incorrect assumptions about the customs value or Incoterms
- Importer EORI or VAT details not confirmed
- Freight, insurance or other valuation elements not provided
- Arrival details and release arrangements not agreed in time
- Whether the goods qualify for a relief or special customs procedure
How the process works
- Tell us what is being imported, where it is coming from and the expected UK arrival location and date.
- Send the commercial invoice, packing list and available transport documents.
- Confirm the UK importer details and provide commodity code, origin and value evidence where available.
- We review the information, identify any missing documents or issues and agree the customs requirements and costs.
- We prepare and submit the import declaration when the required details are available.
- Once customs release is confirmed, we coordinate the agreed handover and any related transport arrangements.


Why choose Cartwright CS
Business imports need reliable customs information, not just a one-off entry. We review product details, classification, origin and customs-value evidence alongside the purchase and transport documents.
This supports declarations that finance and operations teams can reconcile later. We also coordinate port-release queries and related customs procedures where agreed, helping regular and first-time importers understand the information each shipment requires.
Location and coverage
Based in Southampton, Cartwright CS supports commercial import customs clearances through ports and entry points across the UK, including Southampton, Portsmouth, Felixstowe, London Gateway, Dover and other locations according to the shipment route.

Frequently asked questions
What documents are needed for a commercial import?
Usually a commercial invoice, packing list and relevant transport documentation, together with UK importer details and appropriate goods information. We will confirm any additional requirements for your shipment.
Do I need a UK EORI number?
A UK importer will generally need an appropriate EORI number for customs declarations. We can check what is required for the proposed import arrangements.
Can you clear a container arriving at a UK port?
Yes. We can assist with the UK customs declaration for containerised commercial imports and coordinate the agreed clearance and release steps.
Can you calculate import duty and VAT?
We can review the customs value, classification, origin and supporting evidence to establish the applicable duty and import VAT treatment for the shipment.
Can the goods qualify for reduced duty or a relief?
Potentially, but eligibility depends on the goods, customs procedure, origin evidence and other applicable conditions. Any claim must be supported by appropriate documents.
Can you arrange transport after customs clearance?
We can seek haulage and delivery options through transport partners where requested, subject to the location, cargo, release arrangements and availability.
