Quick answer
A NAICS size standard appeal is a challenge by an offeror to the contracting officer's selection of the NAICS code assigned to a solicitation, filed with the SBA's Office of Hearings and Appeals.
A NAICS size standard appeal is a formal challenge filed with the SBA's Office of Hearings and Appeals (OHA) by an offeror who believes the contracting officer assigned an incorrect NAICS code to a solicitation, thereby applying an inappropriate size standard that either excludes the challenger from small business eligibility or gives the challenger's competitor an unfair size advantage.
What is a NAICS Size Standard Appeal?
The contracting officer is responsible for selecting the NAICS code that best describes the principal purpose of the acquisition. This code determines the applicable size standard (revenue or employee-based) that governs small business eligibility for any set-aside. When an offeror believes the selected NAICS code is incorrect, for example, the officer selected a code with a lower size standard that would disqualify the offeror, when a more applicable code has a higher standard that would qualify it, the offeror may appeal to SBA's OHA under 13 CFR 121.1102.
The appeal must be filed with OHA within 10 calendar days of the solicitation issuance or amendment assigning the disputed NAICS code. The appeal must be simultaneously served on the contracting officer. OHA reviews whether the assigned NAICS code best describes the principal nature of the work, applying the descriptions and rules in the NAICS manual. OHA may sustain the appeal (changing the NAICS code and therefore the size standard) or deny it (confirming the contracting officer's assignment).
A successful NAICS appeal does not guarantee the protestor wins the contract, it only changes the applicable size standard. However, it can meaningfully alter who qualifies as a small business for the set-aside and what competitive pool the solicitation addresses. NAICS appeals must be resolved before offer due dates where possible; if the appeal is filed close to the deadline, OHA may issue an expedited determination.
Why NAICS Size Standard Appeals Matter for Government Contractors
The NAICS code assigned to a solicitation is not always correct, and the stakes are high: two neighboring NAICS codes might carry size standards of $16.5M and $47M respectively, making the difference between qualifying as small or not. Firms that are near the boundary of a size standard should review every relevant solicitation's NAICS assignment carefully. An incorrect assignment that unfairly disqualifies your firm is worth challenging, a successful appeal can reopen eligibility and reshape the competitive landscape before offers are due.
Example
A contracting officer assigns NAICS code 541690 (Other Scientific and Technical Consulting Services, $19M size standard) to a solicitation for environmental remediation support. An environmental consulting firm with $22M in revenue that would qualify under NAICS 562910 (Remediation Services, $22.5M size standard) files a NAICS appeal with SBA OHA within 10 days, arguing the work is primarily remediation, not consulting. OHA agrees, changes the NAICS code to 562910, and the firm now qualifies as a small business eligible for the set-aside.
Frequently Asked Questions
What is the deadline to file a NAICS size standard appeal?
The appeal must be filed with SBA's Office of Hearings and Appeals within 10 calendar days of issuance of the solicitation or the solicitation amendment that assigns the disputed NAICS code. This is an absolute deadline, late appeals are dismissed. Given that solicitations often close within 30 days of issuance, firms must monitor new solicitations closely and act quickly to meet the 10-day window.
Can I appeal the NAICS code even if the solicitation is not a set-aside?
Yes, but the practical significance is different. For full and open (unrestricted) competitions, the NAICS code affects which size standard applies if the contract later includes small business subcontracting plan requirements and which category the award is credited to in FPDS. For set-aside solicitations, the NAICS code directly determines eligibility to compete, making the stakes considerably higher.
Does a NAICS appeal delay the solicitation?
OHA attempts to resolve NAICS appeals quickly to avoid disrupting the procurement schedule. If OHA cannot issue a decision before the offer due date, the agency may extend the deadline pending the decision. In cases where the schedule is immovable, OHA may issue the decision after award, but the contracting officer can then modify the solicitation or re-evaluate eligibility based on OHA's ruling. Agencies prefer to resolve NAICS disputes before award to avoid complications.
Is a NAICS appeal the same as a size protest?
No. A NAICS appeal challenges the contracting officer's choice of NAICS code before offers are submitted. A size protest challenges a specific firm's size status under the assigned code after the apparent awardee is identified. They are distinct proceedings filed at different times and addressing different questions: the NAICS appeal addresses "is the right code being used?" while the size protest addresses "is this firm actually small under that code?"
