U.S. exports of Dredgers (SITC 79351) totaled $23.0M in August 2026.
Importers of Dredgers paid $12K in duties in August 2026, an average duty rate of 3.25% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Dredgers imports of $376K in August 2026 ran 42% above the year-to-date monthly average of $264K.
Last updated: August 2026 dataDredgers are specialized self-propelled or non-self-propelled vessels whose primary function is excavating and removing sediment from waterways, harbors, and offshore areas — a function that governs their SITC classification regardless of hull type or propulsion. In the US market, dredging operations in navigable waters are heavily regulated by the US Army Corps of Engineers, and foreign-flagged dredgers face significant restrictions on domestic work under the Jones Act and the Dredging Act of 1906. Trade in dredgers is therefore concentrated in export markets and international project work rather than domestic US deployment. Buyers evaluating imported dredgers for US coastal or inland projects should obtain legal guidance on coastwise trade restrictions before completing acquisition.

Generally no. The Dredging Act of 1906, reinforced by Jones Act provisions, restricts dredging in US navigable waters to US-built, US-flagged, and US-crewed vessels. Waivers are possible but rarely granted. Foreign-built dredgers imported for US use would typically be limited to non-coastwise applications or require a formal waiver from the Maritime Administration.
The key criterion is that the vessel's primary designed function is excavation and sediment removal, not navigation or cargo transport. A vessel fitted with dredging equipment as a secondary capability would not qualify; the dredging function must be the principal purpose for which the hull was designed and constructed.
