What Happens During a Customs Random Check on an Imported Car

Customs authorities use a mix of random sampling and risk-based targeting to select shipments for physical inspection. Risk factors that increase the chance of selection include a declared value that seems low relative to the vehicle's make and age, inconsistencies between the bill of lading and the import declaration, first-time importers with no prior clearance history, and vehicles arriving from routes flagged for historical smuggling concerns. Purely random selection also occurs regardless of any red flags, typically affecting a set percentage of all imports at a given port.

Officers verify the VIN stamped on the chassis matches the VIN on your V5C and bill of lading, check the odometer reading against any declared mileage, inspect for undeclared goods stowed inside the vehicle (a common and costly mistake covered in our shipping checklist), and may check the engine number against paperwork for engine-size-based duty calculations. They'll also visually assess condition to confirm it matches the declared value used for duty purposes.

A straightforward physical inspection typically adds 2-5 working days to the standard clearance timeline described in our clearance process guide. If discrepancies are found — such as an unlisted spare engine or mismatched VIN — the vehicle can be held for further investigation lasting several weeks, alongside potential fines and storage charges accruing daily.

Most ports charge a nominal inspection or examination fee, typically £50-£150, payable by the importer or their agent. If the vehicle is held beyond the port's free storage allowance (commonly 5-7 days) while inspection or follow-up queries are resolved, demurrage charges of £25-£50 per day can accumulate quickly, so it pays to have your agent respond to any customs query the same day it's raised.

Ensure the declared value, engine size, VIN and mileage on your import declaration exactly match the physical vehicle and its accompanying V5C. Remove all personal items before shipping and provide an accurate packing list if using container shipping. Keep your original purchase invoice and any independent valuation on hand in case the declared value is queried, and use a broker familiar with your specific destination port's inspection tendencies.

Minor discrepancies, such as a slightly different odometer reading due to transit driving at the origin port, are usually resolved with a written explanation from your agent. More serious issues, such as undeclared goods or a mismatched VIN suggesting the wrong vehicle was documented, can result in formal customs proceedings, additional duty assessments, or in rare serious cases, seizure. Responding promptly and transparently with your broker's help is the best way to resolve any query quickly.
