Act promptly when a solicitation NAICS code looks wrong

Published by Federal Bid Partners LLC · October 26, 2026 · Solicitations

A solicitation's code can affect competition and the applicable size standard. If the designated NAICS appears inconsistent with the actual principal purpose, investigate immediately. Do not wait until the proposal deadline to decide whether there is a problem.

FAR 19.102 describes the contracting officer's assignment of the industry that best describes the acquisition's principal purpose, considering the manual, requirement descriptions, component value and importance, and function. Your company's usual code is not enough to show the solicitation code is wrong.

Create a factual comparison

Save the solicitation and affected amendments. Identify the designated code and the candidate alternative, then compare their official definitions with the actual statement of work. Reference specific tasks, deliverables, and available value information rather than arguing from the title alone.

Separate known facts from estimates. If the solicitation does not provide a cost allocation, label your analysis as an estimate and explain the basis. A useful comparison shows why the principal purpose supports the alternative rather than merely showing that some work falls within it.

Fictional example: a bundled requirement

Fictional Quarry Systems sees a notice combining equipment delivery, installation, and ongoing technical services. Its sales team prefers the service classification. The review team examines which component defines the acquisition and whether the official descriptions support that view.

The evidence may support the agency's original choice, an alternative, or an unresolved question. Quarry records the result and assigns a person to monitor amendments. It does not assume that emailing a question automatically changes the designation or preserves a formal filing deadline.

Distinguish clarification from an appeal

SBA's NAICS appeals guidance states a general ten-calendar-day filing period from issuance of the solicitation, or an amendment affecting the code, and provides filing and service requirements. FAR 19.103 addresses appeals and exceptions. Review the controlling rules promptly with qualified counsel when considering a formal appeal.

Do not treat the summary here as a deadline calculator. The triggering document, affected issue, applicable rules, receipt requirements, and exceptions matter. An ordinary agency clarification request is different from a properly filed and served OHA appeal.

• Record the initial issue date and every relevant amendment.
• Preserve the authoritative solicitation documents.
• Compare both official industry definitions.
• Tie arguments to principal-purpose facts.
• Assign immediate review of filing and service requirements.
• Monitor the official notice for changes.

Whether or not you pursue an appeal, keep the comparison record. It helps the business explain its decision and improves future screening. The immediate deliverable is a timely, evidence-based review with an assigned action, not a claim that a different code is guaranteed to be adopted. If the team elects to take no further action, record why and who made that decision. That closes the internal research task without suggesting that an unanswered agency question was formally resolved.
