Small Disadvantaged Business (SDB) Guide: Certification & Contracting Benefits
Complete guide to Small Disadvantaged Business certification. Learn about SDB eligibility, certification process, price evaluation adjustment, and contracting advantages for disadvantaged small businesses.
Quick Answer
Small Disadvantaged Business (SDB) status is available to small businesses that are at least 51% owned and controlled by one or more disadvantaged individuals. SDB status provides access to sole source contracts, set-asides (for DoD), and price evaluation adjustments up to 10%. SDB certification is obtained through the SBA's certify.sba.gov portal.
What is SDB Status?
Small Disadvantaged Business (SDB) status is a federal certification for small businesses owned and controlled by individuals who have been subjected to racial or ethnic prejudice or cultural bias because of their identity as members of a group, without regard to their individual qualities.
SDB certification is distinct from the 8(a) Business Development Program, though there is significant overlap. SDB status provides certain benefits without the full requirements and business development components of the 8(a) program.
Presumed Disadvantaged Groups
SBA presumes the following groups are socially disadvantaged. Individual members still must demonstrate economic disadvantage.
- Black Americans
- Hispanic Americans
- Native Americans
- Asian Pacific Americans
- Subcontinent Asian Americans
- Members of other groups (case-by-case)

Price Evaluation Adjustment
One of the most significant benefits of SDB status is the price evaluation adjustment in competitive acquisitions.
How Price Adjustment Works
In competitive acquisitions where price is a factor, contracting officers may apply up to a 10% price evaluation adjustment for SDB offerors.
Example:
Non-SDB Proposal: $1,000,000
SDB Proposal: $1,050,000
Adjusted Non-SDB: $1,100,000 (+10%)
SDB wins at actual $1,050,000
Adjustment Discretion
The price evaluation adjustment is not automatic. Contracting officers decide whether to apply it based on the specific procurement. It's typically included in solicitations when appropriate.
SDB vs 8(a) Program
SDB certification and the 8(a) Business Development Program are related but distinct.
| Feature | SDB | 8(a) |
|---|---|---|
| Program Term | No limit (recertify every 3 years) | 9 years maximum |
| Sole Source Contracts | Limited (DoD only) | Up to $4.5M / $9M |
| Set-Asides | DoD only | All agencies |
| Business Development | None | SBA support, mentoring |
| Price Adjustment | Up to 10% | Up to 10% (same) |
| Requirements | Less intensive | Annual reviews, business plan |
Success Strategies
Consider 8(a) Program
If you qualify for SDB, you likely qualify for 8(a) which provides more benefits. Consider applying for both or 8(a) directly.
Target DoD
DoD is the primary user of SDB set-asides. Focus your marketing on DoD agencies and prime contractors.
Subcontracting Opportunities
Large businesses need SDB subcontractors to meet their subcontracting plan goals. Market your SDB status to primes.
Update Your Profile
Ensure your SAM.gov and DSBS profiles prominently display your SDB certification for visibility.
Frequently Asked Questions
Can I have both SDB and 8(a) certification?
If you're in the 8(a) program, you automatically have SDB status for the duration of your 8(a) term. You don't need separate SDB certification while in 8(a).
What if I don't belong to a presumed group?
You can still apply for SDB status by providing a narrative and evidence demonstrating social disadvantage based on your individual circumstances. SBA evaluates these on a case-by-case basis.
How long does SDB certification last?
SDB certification is valid for 3 years. You must recertify before expiration to maintain continuous status. Annual updates may be required.
Is SDB certification free?
Yes, SDB certification through SBA is free. Be wary of third parties charging for certification assistance—you can apply directly at certify.sba.gov.
What happens if I exceed economic thresholds?
If your personal net worth or income exceeds the thresholds, you would no longer qualify as economically disadvantaged. You must report changes and may lose certification upon recertification review.
