Since this service is on the procurement list, is a Commercial Item Determination still required?
Yes, a commercial item determination is required to be made in writing for an acquisition exceeding $1M in value. See FAR 12.101, DFARS 212.102
and DFARS PGI 212
.102. See also see page 13 of the DoD Guidebook for Acquiring Commercial Items, Part A: Commercial Item Determination, https://www.acq.osd.mil/dpap/cpic/cp/docs/Guidebook_Part_A_Commercial_Item_Determination_20180129.pdf
FAR part 12
says, agencies shall conduct market research to determine whether commercial items are available that could meet agency needs and to acquire commercial items when they are available. Ultimately, for all requirements, the contracting officer will have to determine if the product/service is commercial in nature.
