Cars brought in from outside the European Union are now cleared exclusively through the CDS system, since the earlier CHIEF system has been fully switched off by the UK customs administration. The declaration must include the EORI number, the vehicle's VIN, and documents confirming its value and origin, on the basis of which customs duty, excise duty and import VAT are calculated. After customs clearance, the vehicle's owner also needs confirmation of VAT settlement (VAT-24) in order to register the car with the Polish vehicle registration office.

How to prepare the process and documents
Division of responsibilities between the parties
When it comes to changes in car clearance, it's essential to be clear about the division of responsibility between the importer, the exporter and the customs representative, since this determines who is authorised to submit declarations and sign customs documents. The importer is responsible for the customs value and classification of the goods, the exporter for the completeness of the export documentation, and the customs representative for the technical correctness of the declaration in the official systems.
Minimum data set for the declaration
To submit a correct customs declaration for a motor vehicle, you need at least: the tariff code (HS/CN), the commercial invoice value, the country of origin, the VIN or chassis number, the gross and net weight, and the details of the parties to the transaction. Missing any of these elements results in the declaration being rejected, or clearance being held up until the gaps are filled.
Comprehensive customs support on the Poland–UK route is provided by a UK customs agency.

Operational stages from pre-notification to release
Most common risk points and how to reduce them
The most common causes of delay in car clearance are: the invoice value not matching the vehicle's market value, incorrect classification (e.g. confusing the HS code for a passenger car and a van), a missing certificate of conformity (CoC) or type-approval certificate, and an out-of-date customs authorisation. It's worth keeping an internal control checklist, filled in before every declaration and checked with the logistics team member responsible.
How to stay compliant and keep your records in order
Archiving, corrections and evidence of due diligence
Customs documents relating to vehicle clearance should be kept for at least four years under HMRC requirements, or five years under EU rules, in either electronic or paper form. If a customs declaration needs correcting, an amendment should be filed through CDS, with evidence attached to support the change in value or classification. Complete documentation is the most important evidence of due diligence during a customs audit.
Working with a customs agency and internal audit
Regular internal audits of customs processes help identify recurring classification or documentation errors before they become grounds for an administrative penalty. Working with an experienced customs agency ensures that regulatory changes — such as updates to the CN nomenclature or new HMRC requirements — are picked up as they happen, without the risk of delays caused by out-of-date internal procedures.
Summary
In summary: when it comes to changes to car clearance, the key is to run the process according to current official guidance, with a clear division of responsibilities and documentation of every decision. This approach reduces delays, cuts the number of corrections needed and makes it easier to defend your figures during an inspection. If any requirement is unclear, check the current GOV.UK guidance or consult an experienced customs agency.
Legal basis and sources
If regulations or system notices are updated, check the current GOV.UK or KAS guidance before submitting a declaration.
Frequently asked questions
What documents are required for customs clearance of a car imported into the United Kingdom?
To clear a car imported into the UK, you need: a commercial invoice, a certificate of conformity (CoC) or type-approval certificate, the vehicle's VIN, a transport document (CMR or bill of lading), a declaration of customs value, and — for used vehicles — the registration document from the country of export. Missing any of these documents results in clearance being held up.
How have post-Brexit changes affected car clearance between Poland and the United Kingdom?
Since Brexit, vehicles moved between Poland and the UK are subject to the full customs procedure — both on the EU export side (an EX declaration) and on UK import (an IM declaration through CDS). The HS code, customs value and country of origin all need to be established. Cars may be subject to import duty if they don't meet the rules of origin under the UK–EU TCA.
What does the precautionary principle mean in the context of car customs clearance?
The precautionary principle means checking the current state of HMRC or EU customs administration rules and notices before finally submitting the customs declaration. It's particularly important to check that the customs duty rates are current, that the TCA tariff preferences still apply, and the status of the electronic systems — CDS in the UK and AES in the EU — since system outages can affect the validity and timing of a submitted declaration.
Who is responsible for the correctness of the customs declaration when importing a car — the importer or the customs agency?
The importer, as the declarant, is responsible for the correctness of the customs declaration, even when using a customs agency's services. An agency acting under a direct authorisation takes on joint and several liability for the data in the declaration. Errors resulting from incorrect information supplied by the importer do not release it from liability to the customs authority, or from the obligation to pay any duty shortfall.
How long do customs documents relating to car clearance need to be kept?
Customs documents relating to car clearance should be kept for at least four years under HMRC (UK) requirements, or five years under EU rules (UCC art. 51). This covers invoices, customs declarations, confirmation of release, proof of payment of customs duty and import VAT, and all correspondence with the customs office. Electronic storage is acceptable, provided the documents remain legible and available on request to the inspecting authority.
