Federal obligations in other support activities for water transportation (NAICS 488390)

Residual marine support at $785.6M

Water transportation needs more than docks and brokers: vessel servicing, marine cargo handling outside the port-ops code, and related residual support land in 488390. Federal maritime and defense buyers tag $785.6M of contract obligations to that residual on 1,574 awards. The figure is not a vessel count and not a berth-day total.

Port and harbor operations (488310) are a named neighbor. Freight transportation arrangement (488510) is brokerage. $785.6M follows the 488390 residual. Packet facts are the dollar total and the 1,574 count. Ship names and pier lists are not in the harvest.

1,574 awards and a mid-size marine average

One thousand five hundred seventy-four awards against $785.6M averages about $499,000 per action. That scale fits multi-month marine-support packages better than a single line-handling ticket. Modifications still add to 1,574, so the count is not unique vendors and not unique vessels.

Large Navy or civilian marine-support vehicles can dominate $785.6M even with 1,574 rows on the hub. Amount sort separates those from the smaller residual tickets. The simple average is a divider, not a typical day-rate.

488390 versus named water-transport codes

If the action is port and harbor operations, it belongs in 488310. If it is freight brokerage, it belongs in 488510. 488390 is the leftover water-transport support class. Dual-role marine firms can be tagged either way. $785.6M stays with 488390 on 1,574 tagged actions.

Cite the extract as $785.6M in USAspending contract obligations tagged to NAICS 488390, other support activities for water transportation, on 1,574 awards. The packet has no fiscal year. Live tables can shift; the harvested pair remains $785.6M and 1,574.

Committed marine support, not outlays

Marine-support contracts often obligate a period and pay as services are accepted. $785.6M is committed value on 1,574 tagged actions, not cash already paid for every assist. Terminations de-obligate. Outlay fields track payments.

Classification errors sit where port ops and residual support overlap. Keep $785.6M attached to 488390 as tagged, then inspect the 1,574 descriptions. This overlay does not merge 488310 or 488510 dollars into the residual cell.

The about $499,000 average fits multi-month marine-support packages. Modifications inflate 1,574 relative to unique vendors.
