Framework Quality & Manufacturing
21 CFR 111
21 CFR Part 111 is the FDA regulation setting current good manufacturing practice (cGMP) for dietary supplements.
It applies to anyone who manufactures, packages, labels, or holds a dietary supplement for sale in the United States, and it is built around one idea: every product must be made consistently according to a written master manufacturing record, with a batch record proving it was.
In writing, Part 111 demands a lot: written procedures for personnel hygiene, sanitation, equipment calibration and maintenance, quality control operations, receiving and testing components, manufacturing, packaging and labeling, holding and distribution, returned products, and complaints.
It requires a master manufacturing record for each formulation and batch size, a batch production record for every batch, specifications for components and finished products, and records showing the quality control unit reviewed and approved each step. The FDA inspects against these documents.
Who has to comply
Any domestic or foreign firm that manufactures, packages, labels, or holds dietary supplements for the US market, including contract manufacturers and own-label distributors who hold product. Retailers holding product only for direct sale to consumers are excluded. Small-firm phase-ins ended years ago; all sizes are covered.
What the assessor asks to see
Facility registration and organization chart; written procedures across all Part 111 subparts; master manufacturing records for each product and batch size; batch production records with quality control review and sign-off; component, in-process, and finished product specifications and test results; supplier qualification and certificate of analysis verification; equipment calibration, cleaning, and maintenance logs; personnel training and hygiene records; laboratory controls and out-of-specification investigations; product complaint files and adverse event records; returned and reprocessed product records; label and packaging control records; distribution records supporting recall.
Where the requirement sits: 111.14 personnel qualifications/training; 111.103, 111.123 etc. 'written procedures'; 111.605 records

Consultants
Who helps with 21 CFR 111
A well-developed cGMP consultant ecosystem exists, often staffed by former FDA investigators and quality managers. Consultants run mock inspections, write the procedure set and master manufacturing records, set up specification programs and supplier qualification, train staff, and help respond to FDA Form 483 observations and warning letters.
Third-party cGMP certification programs (for example NSF/ANSI 455-2 or the UL or USP programs) are voluntary add-ons that retailers sometimes require.
