Maritime Administration sits inside the Department of Transportation and manages U.S. maritime trade, the Merchant Marine, and a fleet of ready-reserve vessels. It is not a household name in the small business contracting world, but it spends roughly $1 billion per year and has a dedicated small business program that actively seeks diverse vendors. If your business touches shipbuilding, port logistics, engineering, or technical services, this agency is worth your attention.
What MARAD actually buys
The bulk of MARAD's procurement falls into a few categories. Ship construction, overhaul, and repair dominate the spend. The agency maintains the Ready Reserve Force, a fleet of cargo ships that can be activated during national emergencies. Those ships need regular maintenance, drydock work, and system upgrades. Contracts in this category can run from a few hundred thousand dollars for individual repairs to multi-million-dollar overhaul packages.
Engineering and technical services are a consistent secondary category. MARAD funds port infrastructure studies, environmental assessments for maritime projects, and engineering design work for harbor improvements. These contracts tend to run $500,000 to $5 million and often go to firms with Civil or Marine Engineering credentials.
Professional and IT services round out the spend. The agency buys program management support, data systems work, training development, and administrative services. Contract sizes here are smaller, typically $250,000 to $2 million, and they cycle more frequently, which creates entry points for firms that are not in the shipbuilding business.
Primary NAICS codes
If you are building your capabilities around MARAD, these three NAICS codes cover the core spend:
336611 (Ship Building and Repairing): The largest single category. Covers vessel construction, conversion, and repair. Set-aside opportunities in this code exist but require genuine shipyard capability or verified subcontracting relationships with a prime.
488330 (Navigational Services to Shipping): Port and harbor services, vessel traffic management support, and related maritime logistics. Smaller contract base but less competition from large primes.
541330 (Engineering Services): Marine engineering, port design, coastal infrastructure studies. This is where firms with licensed engineers find the most consistent pipeline.
Search SAM.gov for active MARAD opportunities filtered by these codes before you invest time in registration and outreach.
How to register and get into the vendor ecosystem
Start with the basics. Your business needs an active SAM.gov registration with current certifications listed. MARAD contracting officers pull SAM records directly when evaluating set-aside eligibility, so an expired registration costs you real opportunities. Renew annually and update your NAICS codes to include all three listed above if they apply.
Get your SBA certifications current. MARAD uses the standard federal set-aside program: 8(a), HUBZone, WOSB/EDWOSB, and SDVOSB. The agency's small business goals are reported annually to the SBA as part of DOT's government-wide scorecard. Agencies with active reporting pressure tend to use set-asides more consistently, and DOT as a whole has historically performed above the small business prime contracting goal. MARAD benefits from that institutional attention.
If you hold an 8(a) certification, sole-source awards are available for contracts under $4.5 million for services ($7.5 million for manufacturing). MARAD has historically used this mechanism for technical support and engineering work. A strong 8(a) presentation directly to the small business office can generate a sole-source conversation before a solicitation even hits SAM.gov.
MARAD's small business office
The Office of Small and Disadvantaged Business Utilization (OSDBU) for the Department of Transportation serves all DOT modal administrations, including MARAD. DOT OSDBU is one of the more active in the federal government. They hold vendor outreach events, publish forecasts, and maintain an online vendor registration system separate from SAM.gov called the Transportation Vendor Registration System (TVR).
Register in TVR. Contracting officers and program offices inside DOT use it to source small businesses for market research. It takes about 20 minutes and it is free.
The DOT OSDBU website (transportation.gov/osdbu) lists upcoming matchmaking events and agency-specific small business liaisons. MARAD has a designated small business specialist who works within the agency's contracting shop. You can reach that person through the DOT OSDBU office or by contacting MARAD's headquarters contracting division in Washington, D.C. Do not cold-email a contracting officer. Go through the small business specialist first. They exist to make these introductions.
Set-aside and diversity opportunities
MARAD publishes a small business forecast as part of DOT's annual forecast of contracting opportunities. You can find this at transportation.gov/osdbu/forecast. It lists anticipated contracts by value, type, and NAICS code. It is updated throughout the year and it is one of the best early-warning systems you have for upcoming work.
Beyond the standard SBA set-aside categories, MARAD participates in the Mentor-Protégé program administered by SBA. If you can secure a mentor relationship with one of the large defense or maritime contractors that holds MARAD vehicles, that relationship gives you access to joint ventures, subcontracting credits, and direct introductions to program offices.
Subcontracting is a realistic entry point. Large prime contractors on MARAD vessel maintenance contracts are required to file subcontracting plans and hit small business subcontracting goals. You can find the names of prime contractors on active MARAD contracts through USASpending.gov. Filter by awarding agency (Maritime Administration, FAIN or PIID starting with DTMA) and look at who holds the large vehicle maintenance and repair contracts. Contact their supplier diversity or small business subcontracting offices directly.
One practical tip for your first contract
Search USASpending.gov for MARAD contracts in your NAICS code that were awarded in the past 24 months and are valued under $250,000. These smaller awards are frequently re-competed and rarely attract more than three or four bidders. Pick two or three that align closely with your capabilities and call the contracting officer listed in the award record. Introduce yourself, confirm whether the work will recur, and ask if there is an upcoming small business sources sought notice. That 10-minute call will do more for your pipeline than six months of passive SAM.gov monitoring.
MARAD is a niche agency, which works in your favor. The contracting office is small, the program offices are accessible, and a vendor who shows up consistently, registers correctly, and follows the forecast will stand out. The maritime industry has high barriers to entry on the prime side, but the engineering services, professional services, and IT categories are open to qualified diverse small businesses who put in the groundwork.
