Frequently asked questions
What is PSC AJ11?
AJ11 is the research and development code in the federal Product and Service Code (PSC) Manual for general science and technology r&d services; general science and technology; basic research, under AJ (General Science and Technology R&D Services) and AJ1 (R&D – Physical Science). Agencies put a PSC on every contract to record what they bought.
What is the difference between a PSC and a NAICS code?
A PSC describes what the government is buying. A NAICS code describes the industry of the business doing the work, and it sets the SBA size standard for small business set-asides. Every contract notice has both.
Which NAICS code goes with PSC AJ11?
Most federal contract dollars under PSC AJ11 go with NAICS 541715 (Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology)), according to USAspending.gov. The contracting officer picks the NAICS code for each solicitation, so check the notice.
