DFARS
Defense Federal Acquisition Regulation Supplement
What it actually means
The DoD's supplement to the Federal Acquisition Regulation — the extra layer of rules and contract clauses specific to defense procurement, from specialty metals restrictions to the cybersecurity clauses that impose NIST 800-171 on contractors. Most compliance obligations contractors complain about live in DFARS clauses.
Where you'll meet it
Contract clause lists and compliance reviews; cited constantly alongside the FAR.
