What is PSC AS23?

AS23 is the research and development code in the federal Product and Service Code (PSC) Manual named “Transportation R&D Services; Aerospace Research; Experimental Development”, under AS (Transportation R&D Services) and AS2 (R&D – Trans – Motor Veh). Agencies put a PSC on every contract to record what they bought.
