Foreign Remaining on Board (FROB)
(United States) Cargo that is loaded in a foreign port and which is to be unloaded in another foreign port with an intervening vessel stop in one or more ports in the United States. U.S. Customs and Border Protection considers “FROB” cargo a security concern because although the cargo does not have a final destination in the U.S., the cargo is transiting the U.S. Currently, carriers must correctly report FROB cargo upon arrival in the United States. Under the new regulations, FROB cargo must be reported 24 hours in advance of loading at the foreign port.
