You have won a bid to build for the Department of Defense. Congratulations. Now you need a performance bond—or you cannot start work. Unlike standard construction bonds, DoD performance bonds come with unique dollar thresholds, specific regulations, and even a separate track for freight carriers moving military cargo. Miss one requirement and you could lose the contract. Here is exactly what you need to know, based on the top ten authoritative sources.
The Short Answer: What Is a DoD Performance Bond?
A Department of Defense performance bond is a guarantee from a surety company that a contractor will complete a DoD project according to contract terms. If you fail, the surety pays the government to finish the job—and you repay the surety in full. For freight carriers moving military cargo, the bond guarantees timely pickup, transport, and delivery of defense supplies under the Military Surface Deployment and Distribution Command (SDDC).
Two very different bonds share the same name. Make sure you know which one applies to you.
Construction Contractors: The Miller Act and DFARS Rules
Who needs it: Any prime contractor or subcontractor working on a DoD construction project exceeding $150,000 must provide a performance bond for 100% of the contract value. This comes from the Miller Act (40 USC 3131) and the Defense Federal Acquisition Regulation Supplement (DFARS) Subpart 228.1.
Where the authority lives: 48 CFR 228.102(b)(1) states that for fixed-price construction subcontracts over $150,000, you need a performance bond equal to the subcontract value if available at no additional cost.
What about cost-reimbursement contracts? The bond requirement is waived for cost-reimbursement contracts, but fixed-price subcontracts under those contracts still require bonds.
Environmental restoration exception: For Defense Environmental Restoration Program contracts (cleanup of contaminated military sites), the surety’s liability is limited to the cost of completion minus unexpended funds. The surety is not liable for personal injury or property damage claims, even if caused by the contractor’s breach.
| Contract Type | Bond Required? | Amount |
|---|---|---|
| Fixed-price construction > $150,000 | Yes | 100% of contract value |
| Cost-reimbursement construction | No | N/A |
| Environmental restoration | Yes (modified) | Cost to complete only |
| Subcontract under DoD prime > $150,000 | Yes | 100% of subcontract value |
Freight Carriers: The SDDC Performance Bond
Who needs it: Any Transportation Service Provider (TSP) moving military cargo—including freight carriers, freight forwarders, brokers, and logistics companies—must obtain an SDDC freight carrier bond. Exceptions include local drayage, commercial zone carriers, barge, rail, sealift, and pipeline carriers.
Bond amounts:
| Carrier Type | Bond Amount |
|---|---|
| Domestic carrier, 1 state | $25,000 |
| Domestic carrier, 2-3 states | $50,000 |
| Domestic carrier, 4+ states | $100,000 |
| Surface freight forwarder / logistics company | $100,000 |
| Air freight forwarder | $100,000 |
| Bulk fuel carrier | $25,000 |
| International program participant | $100,000 or 2.5% of prior-year international DoD revenue (greater) |
Alternative calculation: Carriers with 3+ years of DoD experience may post a bond equal to 2.5% of their prior 12 months of DoD revenue instead of the fixed tier amounts.
Critical prerequisite: You must have a Standard Carrier Alpha Code (SCAC) from the National Motor Freight Traffic Association before you can apply for the bond.
How to Get a Department of Defense Performance Bond
Getting a DoD performance bond follows the same four-step process as any surety bond, but the underwriting is stricter because the government is the obligee. Specialists like Swiftbonds have placed these bonds for contractors and freight carriers since 2008, and they know exactly how to present your financials to A.M. Best A-rated, Treasury-listed sureties. Here is the process:
- Apply: Complete a surety bond application with your company financials, credit information, and the specific DoD contract or SDDC registration details. For freight carriers, have your SCAC code ready.
- Quote: Within hours, the surety returns a premium quote. For construction bonds, expect 0.75%-3% of the contract value. For SDDC bonds, expect 1%-3% of the bond amount ($250 to $3,000 per year).
- Pay: You pay the premium. Most sureties accept credit card, ACH, or wire transfer.
- File: You receive the executed bond and file it with the contracting officer (for construction) or with SDDC as part of your carrier application.

What Happens If You Win a DoD Contract but Cannot Get the Bond?
This is serious. Under 10 USC 3247, the Secretary of Defense may require that a bid be accompanied by a written guaranty. If you win but then fail to furnish the required bond, the government can award the contract to the next lowest bidder and charge you the difference between your bid and theirs. That amount is immediately recoverable by the United States.
Do not bid unless you are confident you can obtain the bond.
Frequently Asked Questions
Q: Is the Miller Act threshold still $150,000 for DoD contracts?
Yes. The 2022 National Defense Authorization Act exempted the Miller Act from inflation indexing, so the threshold remains $150,000 and will not automatically increase.
Q: Can I use any surety company for a DoD bond?
No. The surety must appear on the U.S. Treasury Department’s list of acceptable sureties (31 CFR part 223). Most large, A.M. Best A-rated sureties qualify.
Q: Do I need a payment bond as well?
For construction contracts over $150,000, yes. The Miller Act requires both a performance bond and a payment bond. The payment bond protects subcontractors and material suppliers.
Q: What is the difference between a bid bond and a performance bond?
A bid bond guarantees that you will enter the contract at your bid price if you win. A performance bond guarantees that you will complete the work. For DoD construction over $150,000, you typically need both.
Q: I am a subcontractor, not a prime contractor. Do I still need a bond?
If you have a fixed-price construction subcontract over $150,000 with a DoD prime contractor, you must provide a performance bond to the prime contractor.
Q: How long does an SDDC bond last?
The bond remains in effect as long as you are an approved SDDC carrier. You must maintain continuous coverage. Lapsing your bond can result in suspension from military freight hauling.
5 Interesting Things About DoD Performance Bonds Not in the Top 10 Sites
- The Heard Act of 1894 came first. Before the Miller Act of 1935, the Heard Act governed federal construction bonds. It was less specific about bond amounts, leading to frequent lawsuits. The Miller Act cleaned up the language and established the modern 100% performance bond requirement.
- DoD bonds can be required for demolition contracts too. Even though the Miller Act primarily covers new construction, FAR 37.302 allows contracting officers to require performance bonds for dismantling, demolition, or removal of improvements when necessary to protect government property.
- The surety’s liability on environmental restoration contracts is capped by statute. For Defense Environmental Restoration Program contracts, the surety is only liable for the cost of completion minus unexpended funds. The surety is not liable for personal injury or property damage claims, even if directly caused by the contractor’s breach. This is unusual—most performance bonds do not have such a statutory cap.
- SDDC bonds are unique to DoD. No other federal agency requires a freight carrier performance bond structured exactly like the SDDC bond. The U.S. Transportation Command (USTRANSCOM) oversees this program, making it a one-of-a-kind requirement in federal logistics.
- You can be charged the bid difference even if you back out before signing.Under 10 USC 3247, if you win a DoD contract but then fail to furnish the required bond—even before the contract is formally awarded—the government can still charge you the difference between your bid and the next bidder. This is not a penalty clause; it is statutory damages.
Conclusion
DoD performance bonds fall into two completely separate categories. Construction contractors follow the Miller Act and DFARS, with a $150,000 threshold and a 100% bond requirement. Freight carriers follow SDDC regulations, with bond amounts ranging from $25,000 to $100,000 (or 2.5% of prior DoD revenue). Both require sureties from the Treasury Department’s approved list. Both carry serious consequences if you fail to obtain the bond after winning a bid. Know which category applies to you. Get the bond before you bid.
