PSC and NAICS

Every federal award carries two codes. The NAICS code describes the kind of business the buyer expects to do the work; the PSC describes what is being bought. A machine shop and a distributor can both sell the same part, so following a PSC catches work that NAICS filters miss. The NAICS codes that pair with this PSC are listed above; each links to its own page.

Members can watch a PSC, filter every list by it, and see notices and recompetes for it in one place.
