Who counts as small under this code
FedSift does not hold the SBA size standard for NAICS 221320. Check SBA's table of size standards before relying on small-business status.
Each solicitation carries exactly one NAICS code, and that code — not a related one in the same family — decides who counts as small.
One code, chosen by the contracting officer, decides who counts as small. A related code in the same family does not qualify you, and the assignment itself can be appealed to SBA OHA.
