Which code does this activity belong in?
Port and harbor operations establishments own or operate the physical infrastructure of ports, harbors, docking facilities, and piers. The boundary between this code and marine cargo handling turns on whether the establishment operates the facility itself or performs the loading, unloading, and movement of cargo within it; cargo handling activities are classified in Marine Cargo Handling. Navigational services to shipping, such as piloting vessels or providing tugboat assistance, are separately classified despite occurring within harbor areas.
