GMP isn't a certification you earn — it's an FDA regulatory requirement, which puts it in a different category than ISO 9001 or HACCP entirely. How the three actually relate, and what an FDA inspection looks for.
GMP isn’t a certification you earn — it’s a federal regulatory floor
you’re either meeting or you’re not. That’s the single biggest confusion
worth clearing up before anything else: there’s no GMP certificate to
hang on the wall the way there is for ISO 9001.
Good Manufacturing Practice (GMP, often “cGMP” for “current” GMP) is a
set of FDA regulatory requirements covering facility hygiene, equipment
maintenance, documentation, and batch records for products the FDA
regulates — primarily food, pharmaceuticals, dietary supplements, and
medical devices. “Current” signals the FDA expects manufacturers to use
contemporary methods and technology, not that cGMP is a different or
newer standard than GMP — the terms are used interchangeably in
practice.
| GMP / cGMP | ISO 9001 | HACCP | |
|---|---|---|---|
| Nature | Regulatory requirement | Voluntary standard | Regulatory/systematic method |
| Mandatory? | Yes, for FDA-regulated products | No — often customer-required, not legally required | Yes for seafood, juice, meat, poultry; other foods shifting to HARPC |
| Covers | Facility hygiene, equipment, documentation, batch records | Broad quality management system — customer focus, process control, continuous improvement | Hazard identification at specific critical control points |
| Applies to | Food, drug, supplement, cosmetic, device manufacturers | Any industry | Food processors specifically |
GMP is often described as the “prerequisite program” HACCP builds on
— GMP handles the baseline hygiene and facility conditions, while HACCP
layers specific hazard analysis on top for food safety. ISO 9001 is a
genuinely separate track: a voluntary, broadly applicable quality
management certification that doesn’t certify product safety the way GMP
compliance and HACCP do.
If your product falls under FDA regulation — food and beverage,
pharmaceuticals, dietary supplements, cosmetics, or medical devices —
GMP compliance isn’t optional, and staff working in production,
packaging, and quality roles need real GMP literacy, not just a
certificate to file away. If you’re not making an FDA-regulated product,
GMP genuinely doesn’t apply to you the way it would to a food or pharma
manufacturer — that’s worth knowing before investing time in training
aimed at the wrong regulatory framework.
South Carolina has a substantial food, beverage, and agribusiness
manufacturing base, along with some pharmaceutical manufacturing — this
is a real, active compliance area for a meaningful share of the state’s
manufacturers, not a niche concern.
New hires in these industries especially benefit from GMP training
early, since a lot of GMP compliance comes down to habits that feel like
common sense once explained but aren’t automatic without training —
proper handwashing and gowning procedures, keeping personal items out of
production areas, understanding why a specific piece of equipment gets
cleaned on a specific schedule rather than “when it looks dirty.” Most
GMP violations trace back to a habit gap like this, not a dramatic
failure.
An FDA GMP inspection isn’t primarily about whether a facility looks
clean on the day of the visit — it’s about whether the documentation
proves the facility is consistently controlled every day, not just the
day someone’s watching. Investigators look for complete, contemporaneous
batch records, evidence that equipment cleaning and maintenance actually
happened on schedule, and a paper trail connecting raw materials through
to finished product. A spotless facility with gaps in its records is a
bigger red flag than a facility with minor physical issues but airtight
documentation, because the records are what prove control exists when no
one’s watching.
This is also where GMP and a formal quality management system start
to overlap in practice, even though they’re legally distinct: the
documentation discipline ISO 9001 builds — traceability, corrective
action records, change control — is largely the same discipline that
makes GMP compliance defensible during an inspection, even though one is
voluntary and the other is a regulatory floor.
GMP-specific training isn’t a standalone course in SCMEP’s current
catalog — the quality management foundation it builds on is covered in
our Quality and Inspection training,
including AS9100 and ISO 9001:2015 overview courses. As a
NIST Manufacturing Extension Partnership affiliate
serving South Carolina manufacturers since 1989, our focus is
helping you understand which regulatory framework actually applies to
your product before investing in the wrong training.

quality program, you can

No. GMP (Good Manufacturing Practice) is an FDA regulatory requirement, not a voluntary certification like ISO 9001. There’s no single GMP certificate — compliance is enforced through FDA inspection and regulation, primarily under 21 CFR for food, drugs, supplements, and devices.
They’re used interchangeably. “Current” (cGMP) signals that the FDA expects manufacturers to use contemporary methods and technology, not that cGMP is a separate or newer standard from GMP.
No. GMP is a mandatory FDA regulatory requirement for food, drug, supplement, cosmetic, and device manufacturers. ISO 9001 is a voluntary, industry-agnostic quality management system certification that doesn’t specifically certify product safety.
Staff at manufacturers of FDA-regulated products — food and beverage, pharmaceuticals, dietary supplements, cosmetics, and medical devices — particularly in production, packaging, and quality roles.
