- SBA size standards vary by industry and are generally based on annual receipts or employee count.
- SBA establishes size standards industry by industry, and FAR 19.102 states that size status includes affiliates.
- WOSB set-asides are restricted to specific NAICS codes where the SBA has identified underrepresentation of women-owned businesses.
- FAR 19.102 makes the contracting officer’s NAICS designation final unless it is appealed under the stated procedure.
The Relationship: NAICS to Set-Aside
Understanding the chain from industry code to contract eligibility
The Officer Assigns the Code
FAR 19.102 directs the contracting officer to select the code that best describes the acquisition’s principal purpose.
The Code Has a Size Standard
SBA establishes industry-by-industry size standards, and FAR 19.102 links the assigned code with its corresponding standard.
SBA Determines Size
FAR 19.102 states that SBA determines size status, including affiliates, based on the concern’s representation in its initial offer.
Program Rules Still Apply
SBA Certifications publishes WOSB and HUBZone eligibility requirements and links to its other certification programs.
Official Verification Checklist
Verify the assigned code, size standard, representation, and program status against current official sources.
| Check | Official source | Action |
|---|---|---|
| Assigned code | Current solicitation and FAR 19.102 | Confirm the NAICS code selected for the acquisition. |
| Size standard | Current solicitation and SBA size standards | Use the standard corresponding to the assigned code. |
| Size representation | FAR 19.301-1, FAR 19.301-2, and the offer instructions | Apply the relevant representation or rerepresentation rule. |
| Program eligibility | SBA Certifications and the solicitation | Verify every program-specific certification requirement. |
WOSB and EDWOSB competition is limited to SBA-designated NAICS codes. Verify current size rules at SBA.gov.
How to Check Your Set-Aside Eligibility
Use this as an orientation checklist, then verify the current SBA rules and the official solicitation
Check NAICS references
Open the Census Bureau NAICS search tool, then check the corresponding SBA size standard.
Read the solicitation
Confirm the assigned NAICS code, size standard, set-aside type, representation language, offer deadline, and any program-specific conditions in the current notice and amendments.
Use the current SBA standard
Open the SBA Size Standards Tool or current table for the assigned code. Standards and calculation rules can change, so avoid relying on an old copied threshold.
Apply the full size rules
Calculate receipts or employees using the current rule and include affiliates where required. Seek qualified advice when ownership, control, joint ventures, mergers, or recertification make the analysis complex.
Verify program eligibility
Use SBA Certifications to check the current eligibility rules, application process, and status for 8(a), HUBZone, SDVOSB, WOSB, or EDWOSB when the solicitation requires a program status.
Keep official records current
Maintain accurate SAM.gov representations and any required SBA certification record, then follow the solicitation instructions. The contracting agency and SBA make official determinations.
Common Mistakes to Avoid
Common errors that can create eligibility, protest, or proposal risk
Choosing the Wrong NAICS Code
Do not select a preferred size standard in place of the code assigned by the solicitation. SBA provides a time-limited NAICS appeal process when an interested party believes the assigned code is incorrect.
Not Checking Size Standards
Check the assigned NAICS code, current SBA size standard, and the affiliation rule before making a size representation for an offer.
Assuming All Set-Asides Apply
SBA states that WOSB and EDWOSB competitions use designated industries and that each program has its own standards and certification process. Verify the current record and solicitation.
Why This Matters for Contractors
FAR 19.102 connects the assigned NAICS code to its corresponding SBA size standard. SBA also limits WOSB and EDWOSB competitions to designated industries.
Treat eligibility as a current, procurement-specific verification task. Use the official solicitation, the SBA Size Standards Tool, the SBA certification record, and current regulations; this guide does not determine whether a business qualifies.

Frequently Asked Questions
Common questions about NAICS codes and set-aside eligibility
Can my NAICS code change which set-asides I qualify for?
The NAICS code assigned to a solicitation determines which SBA size standard applies to that procurement. Some programs, including WOSB and EDWOSB, also use an SBA-maintained list of eligible industries. FAR 19.102 directs size determinations to include affiliates, and SBA publishes separate certification rules for its programs.
How many NAICS codes can a business have?
SBA states that a business generally has a primary NAICS code and can also have multiple codes when it sells multiple products or services. FAR 19.102 links each solicitation, contract, and order to an assigned NAICS code and corresponding size standard.
Who assigns the NAICS code to a government contract?
The contracting officer assigns the NAICS code based on the principal purpose of the acquisition. SBA currently states that its Office of Hearings and Appeals must receive a NAICS-code appeal within 10 calendar days after issuance of the solicitation, or after an amendment that changes the code. Review SBA’s current NAICS Appeals instructions and controlling regulations before filing.
Which size rule should I check for a new offer?
For a new offer, FAR 19.102 links the assigned NAICS code to its corresponding SBA size standard and states that size status includes affiliates.
Are WOSB set-asides available for all NAICS codes?
No. SBA maintains a current list of industries eligible for WOSB or EDWOSB competition, and its certification page explains the program’s eligibility requirements. Do not infer eligibility from a general industry label.
