Requires that when the Department of Transportation (DOT) buys or finances equipment, materials, or commodities that can move by ocean, 100% of those ocean‑shippable items must be carried on U.S.-flag, privately owned commercial vessels. This applies as long as U.S.-flag ships are available at fair and reasonable rates and with fair geographic participation.

Today’s general rule is 50% U.S.-flag carriage for government-related ocean shipments. This measure sets a stronger standard for DOT-funded or DOT-procured cargo, while keeping existing safeguards on cost and availability. It also makes technical renumbering changes in the statute.
