(a) Reexamination. Whenever the Customs officer deems it advisable any or all of a passenger's baggage may be sent to the public stores for examination or reexamination. Passengers dissatisfied with the assessment of duty on their baggage may demand a reexamination, provided the articles have not been removed from Customs custody. In either case, a receipt for the baggage to be examined or reexamined shall be given on Customs Form 6051.

(b) Protest. If the passenger remains dissatisfied with the assessment of duty after reexamination, he shall pay the duty assessed and may protest the decision of the port director in accordance with part 174 of this chapter.
