Inland Water Freight Transportation
Description
Inland water freight transportation encompasses establishments that move cargo via lakes, rivers, and intracoastal waterways, excluding the Great Lakes System where a separate code applies. This sector relies heavily on commercial vessels of various sizes, ranging from small barges and tugs to large riverboats and barge trains, to facilitate the movement of goods across domestic water networks. Operators primarily function as carriers, freight forwarders, or brokers who manage the logistical aspects of shipping, including loading, unloading, navigating complex waterways, and ensuring regulatory compliance. Activities often involve transporting bulk commodities such as coal, grain, oil, and minerals, as well as manufactured products and containerized freight. The industry plays a critical role in the national economy by offering a cost-effective solution for long-distance heavy freight movements and reducing road congestion. Many businesses operate fleet management systems to track cargo in real time while others focus on specific regional routes. The scale of operations varies significantly, with some entities running single-asset vessels serving local markets, while others coordinate massive, multi-unit barge trains capable of carrying millions of tons annually. This diverse group of establishments contributes substantially to regional trade by leveraging the natural capacity of inland waterways to connect production centers with distribution hubs efficiently.
Hierarchy
| Code | Title | Description |
|---|---|---|
| 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. |
| 4832 | Inland 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. |
