This matter again involves NASA and a particularly interesting government procurement, this time concerning NAICS appeals. NAICS codes, or the North American Industry Classification System codes, are how both businesses are classified by their industry and procurements are classified by what they’re for. If the procurement uses an inappropriate NAICS code, a protestor can appeal this code determination. It is important to note that some NAICS codes have “exceptions” which can affect their corresponding size standards. For example, NAICS code 541330, “Engineering,” has a size standard of $16.5 million, but, if the engineering services are for military equipment and weapons, an exception applies that balloons the size standard to $35.5 million. But, just like regular NAICS codes, these exceptions have to make sense in light of the kind of solicitation in question, leading us to this matter.
