Strangely, the Department of Homeland Security’s Supplemental Federal Acquisition Regulations (HSAR) is not included on the official Code of Federal Regulations website. However, an unofficial online beta test site, the Electronic Code of Federal Regulations (e-CFR), does include the HSAR.  This beta test site is updated daily and also contains the Federal Acquisition Regulation, FAR, as well as the individual agency supplements.  By accessing Title 48 of the CFR on this website, the most recent versions of these regulations were accessible.
