The Code of Federal Regulations (CFR) is the codification of the general and permanent rules published in the Federal Register by the executive departments and agencies of the Federal Government. It is divided into 50 titles that represent broad areas subject to Federal regulation. Each volume of the CFR is updated once each calendar year and is issued on a quarterly basis.
Each title is divided into chapters, which usually bear the name of the issuing agency. Each chapter is further subdivided into parts that cover specific regulatory areas. Large parts may be subdivided into subparts. All parts are organized in sections, and most citations in the CFR are provided at the section level.
Federal statutes furnish the authority and the limits for regulations that
appear in the CFR. This means that the regulations on a subject should be read
together with any pertinent portions of the U.S. Code. [U.S. Code]
It also means that courts will, upon occasion, hold that regulations which appear in the
Code of Federal Regulations are invalid because they conflict with a Federal statute.
