48 CFR § 1.303 - Publication and codification.
(a) Agency-wide acquisition regulations shall be published in the Federal Register as required by law, shall be codified under an assigned chapter in Title 48, Code of Federal Regulations, and shall parallel the FAR in format, arrangement, and numbering system (but see 1.104-1(c)). Coverage in an agency acquisition regulation that implements a specific part, subpart, section, or subsection of the FAR shall be numbered and titled to correspond to the appropriate FAR number and title. Supplementary material for which there is no counterpart in the FAR shall be codified using chapter, part, subpart, section, or subsection numbers of 70 and up (e.g., for the Department of Interior, whose assigned chapter number in Title 48 is 14, part 1470, subpart 1401.70, section 1401.370, or subsection 1401.301-70.)
(b) Issuances under 1.301(a)(2) need not be published in the Federal Register.
