While every federal government contractor is likely familiar with bid protests, whether directly involved in one or not, it is far less likely that those same contractors are as familiar with NAICS code appeals. This is probably due to the infrequent nature of NAICS code appeals, with roughly 20 being filed each year. However, even if so few are filed annually, they tend to have a relatively high success rate, with appeals decided on the merits being decided in favor of the Appellant about 50% of the time. Below, I will take a look at a recent NAICS code appeal to help demonstrate what the Small Business Administration’s (SBA) Office of Hearings and Appeals (OHA) takes into account when reviewing NAICS code appeals, and why you, as a contractor, should review a solicitation’s classification to potentially give you a leg up.
