In circumstances where a recent sale has been made, the customs valuation can be based upon the sale for export document – the commercial invoice, in addition to the freight charges.
However – used cars that have been owned for a signficant period of time may require an alternative valuation method – for example the current price on the UK market. In this circumstance it would be advisable to request for a reputable used car dealer to issue a formal document with the valuation.
