Admission without entry or payment of duty. Trucks, busses, and taxicabs, however owned, which have their principal base of operations in a foreign country and which are engaged in international traffic, arriving with merchandise or passengers destined to points in the United States, or arriving empty or loaded for the purpose of taking out merchandise or passengers, may be admitted without formal entry or the payment of duty. Such vehicles shall not engage in local traffic except as provided in paragraph (c) of this section.

Deposit of registration by vehicle not on regular trip. In any case in which a foreign-based truck, bus, or taxicab admitted under this section is not in use on a regularly scheduled trip, the port director may require that the registration card for the vehicle be deposited pending the return of the vehicle for departure to the country from which it arrived, or the port director may take other appropriate measures to assure the proper use and departure of the vehicle.

Use in local traffic. Foreign-based trucks, busses, and taxicabs admitted under this section shall not engage in local traffic in the United States unless the vehicle comes within one of the following exceptions:

The vehicle may carry merchandise or passengers between points in the United States if such carriage is incidental to the immediately prior or subsequent engagement of that vehicle in international traffic. Any such carriage by the vehicle in the general direction of an export move or as part of the return of the vehicle to its base country shall be considered incidental to its engagement in international traffic. An alien driver will not be permitted to operate a vehicle under this paragraph, unless the driver is in compliance with the applicable regulations of the Immigration and Naturalization Service.

A foreign-based truck trailer may carry merchandise between points in the United States on its departure for a foreign country under the same conditions as are prescribed for “other foreign railroad equipment” in § 123.12(a)(2).

Penalty for improper use. The use of any vehicle referred to in this section in violation of this section may result in liabilities being incurred under section 592, Tariff Act of 1930, as amended (19 U.S.C. 1592).
