What you may need is a USDOT / National Highway Traffic Safety
Administration (NHTSA) Form HS-7, "Declaration" along with a
confirmation letter/fax from AVIONIC saying that it meets the DOT
standards "for the Importation of Motor Vehicles and Motor Vehicle
Equipment subject to Federal Motor Vehicle Safety, Bumper and Theft
Prevention Standards."

I used a Custom$ Broker and he got this paperwork done -
