2022 NAICS subsector in sector 48-49 Transportation and Warehousing
483 Water Transportation
NAICS 483 is the US industry code for water transportation. Industries in the Water Transportation subsector provide water transportation of passengers and cargo using watercraft, such as ships, barges, and boats.
Official definition
Industries in the Water Transportation subsector provide water transportation of passengers and cargo using watercraft, such as ships, barges, and boats.
The subsector is composed of two industry groups: (1) one for deep sea, coastal, and Great Lakes water transportation; and (2) one for inland water transportation. This split typically reflects the difference in equipment used.
Scenic and sightseeing water transportation services are not included in this subsector but are included in Subsector 487, Scenic and Sightseeing Transportation. Although these activities use watercraft, they are different from the activities included in water transportation. Water sightseeing does not usually involve place-to-place transportation; the passenger's trip starts and ends at the same location.
