Did you know that you can import an auto or motorcycle duty-free along with its usual equipment for a temporary stay to take part in an auto race or other specific contest?
But first, the EPA must issue prior written approval that grants only racing vehicles the EPA deems non-capable of practical highway or safe use.

If the contest is not for prize money, a vehicle may be granted a 90 day entry without formal bond if the Customs officer is confident about the importer’s identity and good faith. Keep in mind that the vehicle may be forfeited if a bond is not given or it is not exported within 90 days of its importation. DOT must issue prior written approval.

Cars may be temporarily imported for racing, demonstration or testing purposes. Cars may also be permanently imported for display or show. DOT written approval must be obtained prior in advance when a car is being exported from a foreign country to the U.S.A.
