The Certification Verification Gap
2026 supplement supply-chain data, v2026-07
Data as of: July 3, 2026
Of 747 certification claims published by the 383 active companies in the Inventory Ready directory, 445 (59.6%) cite credential types with no public registry where anyone can check them. Within that group, 286 claims (38.3% of all claims) restate universal legal obligations, mainly cGMP compliance and FDA facility registration, as if they were earned credentials. Where a public registry does exist, 153 of 302 claims (50.7%) have been independently confirmed to date.
A claim that has not been independently confirmed is not evidence that a company misrepresented anything. Many credential types have no public lookup at all, and confirmation work is ongoing. This study describes verification infrastructure across the industry. It is not a quality judgment about any company, and it names no company. Listings on this site are assessed, not verified or certified.

The three classes of certification claims
Every certification claim in the directory falls into one of three classes, based on whether the credential type has a public registry and whether the claim has been confirmed there.
| Class | Claims | Share |
|---|---|---|
| Independently confirmed in a public registry | 153 | 20.5% |
| Registry exists, not yet independently confirmed | 149 | 19.9% |
| No public registry exists for the credential type | 445 | 59.6% |
The middle class partly reflects our own verification queue, and we say so plainly: those claims can be checked, and our confirmation work continues on a rolling basis. The third class is the structural finding. No amount of diligence lets a buyer confirm a credential type that has no public register.
The most-claimed credentials, and whether anyone can check them
| Credential type | Claims | Public registry? | Confirmed |
|---|---|---|---|
| Current Good Manufacturing Practice (cGMP)legal baseline | 167 | No | 0 |
| FDA Facility Registrationlegal baseline | 116 | No | 0 |
| NSF/ANSI 455-2 — Dietary Supplements GMP | 80 | Yes | 78 |
| NSF GMP Registration / Certification | 64 | Yes | 39 |
| USDA Organic Certification | 49 | Yes | 8 |
| Kosher Certification | 35 | No | 0 |
| SQF (Safe Quality Food) Certification | 27 | Yes | 12 |
| Halal Certification | 25 | No | 0 |
| NPA GMP Certification | 22 | Yes | 0 |
| ISO 9001 Quality Management System | 22 | No | 0 |
| ISO/IEC 17025 Laboratory Accreditation | 18 | Yes | 5 |
| NSF Certified for Sport | 18 | Yes | 2 |
Rows marked “legal baseline” are not voluntary certifications. Current Good Manufacturing Practice compliance is required of every dietary supplement manufacturer under 21 CFR Part 111, and FDA facility registration is required under the Bioterrorism Act. Neither can be looked up in a public database, and the FDA does not certify or approve manufacturing facilities. Presenting them as credentials is common industry practice, and it is one reason buyers find certification marketing hard to evaluate.
Findings by service category
Verification depth varies sharply by category, largely because registry coverage does. Contract manufacturing benefits from NSF/ANSI 455-2, which has a public directory updated by NSF. Categories built on service expertise rather than facility audits, such as regulatory consulting, rarely carry facility certifications at all, so low counts there are expected and are not an integrity signal.
| Category | Companies | Claims | Confirmed | No registry |
|---|---|---|---|---|
| Contract Manufacturing | 138 | 412 | 107 | 222 |
| Packaging & Labeling | 75 | 153 | 8 | 111 |
| Ingredient Suppliers | 87 | 109 | 31 | 63 |
| Testing & Stability Labs | 13 | 26 | 5 | 12 |
| Other service categories (4 categories) | 70 | 47 | 2 | 37 |
Categories with fewer than 20 total claims are combined into one row so that aggregate figures stay aggregate. Facility certifications are not an expected signal for consulting and service categories.
What this means for supplement brands
Certification checking cannot be fully outsourced, because for most claimed credential types there is nothing to check against. Three practical steps follow from the data. First, ask any prospective partner for current certificates directly, including scope pages and expiry dates. Second, use the public registries that do exist. Our certifications index lists what each credential actually covers and links to its public database where one exists. Third, treat cGMP and FDA registration language as a legal baseline rather than a differentiator, and ask what third-party audits sit on top of it.
Method
Data. The unit of analysis is a certification claim: one credential named on the public profile of one active company in the Inventory Ready directory. The snapshot covers 383 active companies across 8 supply-chain service categories, of which 309 publish at least one certification claim, for 747 claims in total. Data as of 2026-07-03, version 2026-07. The snapshot is frozen: these figures do not change as the directory grows. Updated editions are issued on a quarterly review cycle with a new version label.
Classification.Each claim maps to a canonical credential type. A type counts as registry-checkable when its issuing body maintains a public register of certified organizations, or, for laboratory accreditation, when the accrediting bodies publish searchable directories. A claim counts as independently confirmed only when we located the company in the relevant public register and recorded the source and date. Claims are never marked confirmed based on a company's own website or marketing materials.
Registers used. NSF certified listings (NSF/ANSI 455-2 GMP, NSF Certified for Sport, NSF GMP); FSSC 22000 Public Register; USDA Organic Integrity Database; SQF public directory; A2LA Directory of Accredited Organizations (ISO/IEC 17025). All register links were load-checked on 2026-07-03.
Limitations. The confirmed count reflects our verification coverage as well as industry practice: some registry-checkable claims have simply not been through our confirmation queue yet, and confirmed counts rise over time. Where a credential type has multiple certifying or accrediting bodies, registry checkability is an approximation based on the bodies our confirmations have used. Agency-unspecified claims, for example a bare kosher or halal label with no named agency, cannot be routed to any register and are classed accordingly. Companies can correct or update their listing at any time through claim your listing.
