DoD is issuing a final rule to amend the Defense Federal Acquisition Regulation Supplement (DFARS) to implement the requirements of sections 851 through 853 and 855 through 857 of the National Defense Authorization Act (NDAA) for Fiscal Year (FY) 2016 (Pub. L. 114-92), as well as the requirements of section 831 of the NDAA for FY 2013 (Pub. L. 112-239), relating to the acquisition of commercial items. This rule also provides guidance to contracting officers to promote consistency and uniformity in the acquisition process. On August 3, 2015, DoD published proposed DFARS rule 2013-D034 to implement the requirements of section 831 (80 FR 45918). Based on the comments received in response to that proposed rule, and in order to implement the requirements in sections 851 through 853 and 855 through 857 of the NDAA for FY 2016, DFARS rule 2013-D034 was closed into this proposed DFARS rule. DoD does not expect this rule to have a significant economic impact on a substantial number of small businesses.
