Deep Sea Freight Transportation
Description
Establishments in the deep sea freight transportation sector specialize in moving large quantities of cargo between international ports, focusing on routes that cannot be efficiently served by smaller vessels. These companies operate massive container ships, bulk carriers, tankers, and specialized roll-on/roll-off vessels designed for long-haul maritime travel across multiple ocean basins. The core business activity involves coordinating complex logistics chains that span from inland gateways to foreign destinations, managing everything from cargo loading and stowage planning to arrival and port discharge operations. Unlike domestic carriers, these operators typically serve as linkages in global supply networks, facilitating trade across continents by handling high-volume, standardized containers as well as bulk commodities like grain, coal, and liquid fuels. The industry consists primarily of major international shipping lines and smaller regional carriers, with the largest firms managing global fleets composed of dozens of ships. On average, a single vessel may traverse thousands of miles per month, often visiting ports in Asia, Europe, and the Americas without stopping for extended periods. The scale of operations is immense, with modern container ships carrying over twenty thousand twenty-foot containers at full capacity. This sector is fundamental to international commerce, enabling the smooth flow of goods that support the economies of nations around the world through reliable and efficient cross-Atlantic and trans-Pacific shipping services.

|---|---|---|
| 48 | Transportation and Warehousing 2-digit sector | The Sector as a Whole The Transportation and Warehousing sector includes industries providing transportation of passengers and cargo, warehousing and storage for goods, scenic and sightseeing transportation, and support activities related to modes of transportation. Establishments in these industries use transportation equipment or transportation-related facilities as a productive asset. The type of equipment depends on the mode of transportation. The modes of transportation are air, rail, water, road, and pipeline. The Transportation and Warehousing sector distinguishes three basic types of activities: subsectors for each mode of transportation, a subsector for warehousing and storage, and a subsector for establishments providing support activities for transportation. In addition, there are subsectors for establishments that provide passenger transportation for scenic and sightseeing purposes, postal services, and courier services. A separate subsector for support activities is established in the sector because, first, support activities for transportation are inherently multimodal, such as freight transportation arrangement, or have multimodal aspects. Secondly, there are production process similarities among the support activity industries. One of the support activities identified in the Support Activities for Transportation subsector is the routine repair and maintenance of transportation equipment (e.g., aircraft at an airport, railroad rolling stock at a railroad terminal, or ships at a harbor or port facility). Such establishments do not perform complete overhauling or rebuilding of transportation equipment (i.e., periodic restoration of transportation equipment to original design specifications) or transportation equipment conversion (i.e., major modification to systems). An establishment that primarily performs factory (or shipyard) overhauls, rebuilding, or conversions of aircraft, railroad rolling stock, or ships is classified in Subsector 336, Transportation Equipment Manufacturing, according to the type of equipment. Many of the establishments in this sector often operate on networks, with physical facilities, labor forces, and equipment spread over an extensive geographic area. Warehousing establishments in this sector are distinguished from merchant wholesaling in that the warehouse establishments do not sell the goods. Excluded from this sector are establishments primarily engaged in providing travel agent, travel arrangement, and reservation services that support transportation establishments, hotels, other businesses, and government agencies. These establishments are classified in Sector 56, Administrative and Support and Waste Management and Remediation Services. Establishments primarily engaged in providing rental and leasing of transportation equipment without operator are classified in Subsector 532, Rental and Leasing Services. Establishments primarily engaged in providing medical care with transportation are classified in Sector 62, Health Care and Social Assistance. |
| 483 | Water Transportation 3-digit subsector | 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. |
| 4831 | Deep Sea, Coastal, and Great Lakes Water Transportation 4-digit industry group | 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. |
| 48311 | Deep Sea, Coastal, and Great Lakes Water Transportation 5-digit NAICS industry | This industry comprises establishments primarily engaged in providing deep sea, coastal, Great Lakes, and St. Lawrence Seaway water transportation. Marine transportation establishments using the facilities of the St. Lawrence Seaway Authority Commission are considered to be using the Great Lakes Water Transportation System. |
