Federal Acquisition Regulations (FAR)


Federal Acquisition Regulations (FAR) apply to all federal contracts, and are used by all federal agencies when they purchase supplies or services.

Some regulations are printed out in their entirety (“Clauses Incorporated in Full”), but others may simply be referenced (“Clauses Incorporated by Reference”).  Even if a regulation is only referenced, it has the same legal weight as if it was printed in full.

It is your responsibility to read and understand these regulations.  You’ll find that many of them refer to standard business practices such as Equal Opportunity, Child Labor Laws and so on.

Not all the regulations listed in a solicitation document necessarily pertain to that particular bid. You may see a list of regulations, but only those marked with an X are relevant.

The FAR is updated regularly, as necessary. You can download the complete current version of the regulations at the website. The regulations are divided into 52 sub-sections, each dealing with a specific aspect of federal acquisition law.

Of particular note to contractors are Parts 12 through 15 (bid types); Part 19 (set-aside programs); and Part 38 (Federal Supply Schedule or GSA contracting)
