A vessel arrives at the port of San Francisco from Yokohama, Japan. The passengers fill out the Baggage Declaration and Entry form. A passenger has baggage arriving on another vessel. How must this baggage be handled for U.S. Customs purposes?

Correct Answer: Option D — It must be declared on the same form and marked "Unaccompanied Baggage".

U.S. Customs and Border Protection regulations require passengers to declare all baggage on a single entry form, designating items arriving separately on a different vessel explicitly as unaccompanied baggage for proper processing.
