US Federal Regulations (CFR)
Rank #161,346smithery/nguyenhieuec/rules
Read a CFR or eCFR section, or search US federal regulations and the Federal Register. Ask "what does 21 CFR 11.10 say?", "which regulations mention respirator fit testing?" or "what has the FDA proposed on food dyes this year?". US Federal Regulations reads two official United States sources directly: the Electronic Code of Federal Regulations (eCFR) for the current text of any section of the Code of Federal Regulations, and the Federal Register for the rules, proposed rules, notices and presidential documents the agencies publish each day. People also call it Rules Lookup.
