IS THE IMPORTED VEHICLE SUBJECT TO TAXES AND DUTIES?
Yes. Whether brand-new or used, purchased or donated, the imported vehicle is subject to 40% Customs duty, 10% VAT and Ad Valorem Tax from 15% to 100% depending on its piston displacement. Its book value serves as the tax base and not the purchase price nor the acquisition cost. The book value is sourced from universally accepted motor vehicle reference books such as the Red Book, Blue Book, World Book depending on the origin of the imported vehicle.
