Certifications are the shorthand buyers use to judge a manufacturer's quality — but a logo on a website tells you very little. Understanding what each certification actually covers, and how to confirm it is real, is one of the highest-value skills in sourcing. Here is the decoder for the ones you will meet most when sourcing from Korea.
ISO 22716 — the cosmetics GMP baseline
ISO 22716 is the international Good Manufacturing Practice standard for cosmetics. It covers the practical realities of making a product safely and consistently: production processes, quality control, personnel, premises and equipment, storage, and shipment. It does not certify any individual product's efficacy or safety — it certifies that the manufacturing system is controlled.
For Korean OEM/ODM, ISO 22716 is effectively a baseline expectation for export-ready production, and both the EU and US (MoCRA) frameworks reference GMP. If a manufacturer targeting international buyers cannot show ISO 22716, treat it as a serious gap.
GMP and CGMP — the same idea, different labels
GMP (Good Manufacturing Practice) is the umbrella concept: documented systems ensuring products are consistently produced and controlled to quality standards. CGMP — "current" GMP — is the term the US FDA and the supplement industry use, stressing that practices must reflect up-to-date standards.
For cosmetics, GMP/CGMP and ISO 22716 are often used interchangeably. For supplements, CGMP refers to a distinct dietary-supplement standard — so if you are sourcing ingestible beauty products like collagen drinks, the relevant certification is supplement GMP, not cosmetics ISO 22716.
Korea's MFDS framework — the regulatory foundation
Underneath the voluntary standards sits the regulator. Korean manufacturers operate under the MFDS (Ministry of Food and Drug Safety), which sets the manufacturing, safety, and labeling rules — including the additional approvals required for functional (quasi-drug) cosmetics. MFDS compliance is a strong baseline quality signal in itself; we cover it in the MFDS registration explainer.
HACCP — for ingestible beauty
HACCP (Hazard Analysis and Critical Control Points) is a preventive food-safety system relevant to supplement and functional-food manufacturing. If your product is ingested rather than applied, HACCP and supplement GMP matter more than cosmetics standards.
What a certificate does — and doesn't — guarantee
This distinction saves brands from false confidence:
- It does confirm the manufacturing system meets a defined standard.
- It does not guarantee your specific formula is safe, effective, or compliant in your target market — that still requires product-level safety assessment (CPSR), stability and challenge testing, and market-specific notification.
Certification is necessary, not sufficient. A certified factory can still make a product that fails your market's rules if the formula or claims are wrong.
How to verify a certificate is genuine
Whenever a manufacturer cites a certification, request the actual certificate and check four things:
- Name and address match the manufacturer you are dealing with.
- Validity dates are current, not expired.
- Scope covers your product type (a cert for one category may not cover another).
- Issuing/accrediting body is a real, recognized organization.
If any of these don't line up, or the supplier resists sharing the document, that is a red flag — see sourcing scams and red flags.
The shortcut
Verifying certifications properly takes time and expertise. A qualified sourcing process does it for you — at OEMKorea we confirm manufacturers' certifications before they reach you. If you would rather start from verified, certified manufacturers, submit an RFQ.
