Trailers must be imported by a Registered Importer (RI) or by someone who has a
contract with an RI, unless they have a U.S. certification label stating the
trailer meets U.S. vehicle safety standards.
Whatever the case may be, either you or the registered importer will have to file an
entry with Customs and submit the DOT form HS-7. Customs will then give you (or the
RI) the entry summary document CF 7501, which is needed to register the trailer in
the state.
If the trailer has a label stating it meets U.S. vehicle safety standards, and is
being imported for personal use, a Customs bond usually is not required. However,
the Customs inspector has the authority to require a Customs bond. If it does not
meet U.S. standards or is intended for resale, a Customs bond must be obtained to
cover the importation. You or the registered importer can obtain a Customs
bond from a surety company. A list of sureties is available on the Treasury Web
site at
www.fms.treas.gov, under publications, circular 570.
Trailers and their parts are provided for in heading 8716 in the Harmonized Tariff
Schedule and are duty free when imported from countries that have normal trade
relations with the United States. Additional information on the DOT
requirements, a list of registered importers, and the form HS-7 can be
obtained at their a href=http://ww.nhtsa.dot.gov/care/rules/import>web site or by calling the Auto Safety Hotline at 1-800-424-9393.
