What are regulations?

In simple terms, regulations are the rules that are created by administrative agencies, (e.g., the Food & Drug Administration), in order to enforce the laws passed by Congress.

Federal Regulations

  • Federal Register is the official daily publication for rules, proposed rules, and notices of Federal agencies and organizations, as well as executive orders and other presidential documents.
  • Code of Federal Regulations (C.F.R.) 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.
