Why every federal contractor needs to know the FAR

The FAR (codified at Title 48 CFR Chapter 1) is the regulation every federal acquisition runs through. It governs how agencies solicit (Parts 12-15), pick contract type (Part 16), award (Parts 14-15), administer (Part 42), and terminate (Part 49). Every solicitation cites the parts it invokes. Every clause in a contract traces back to Part 52. Reading the FAR is how you spot non-standard terms, predict evaluation criteria, and identify which DFARS/agency supplements override the default.

What is the FAR?

The Federal Acquisition Regulation (FAR) is the primary regulation used by all federal executive agencies in their acquisition of supplies and services with appropriated funds. Codified at Title 48, Chapter 1 of the Code of Federal Regulations, the FAR establishes uniform policies and procedures for federal procurement.

Understanding the FAR is essential for any business pursuing government contracts. It governs how agencies solicit, evaluate, award, and administer contracts — from the smallest micro-purchase to multi-billion dollar programs.

Agency supplements (DFARS for DoD, AFFARS for Air Force, NASAFARS for NASA, etc.) modify the FAR's defaults for their specific procurement contexts. When a solicitation cites both the FAR and an agency supplement, the supplement controls where they conflict.
