Classify the manufacturing claim before checking it
Copy the exact statement from the label, website, certificate, or seller listing. Claims such as manufactured in a GMP facility, GMP compliant, GMP certified, FDA registered, FDA inspected, and produced under quality systems do not mean the same thing. Identify who makes the claim and what object it names: a company, facility, production line, process, product, or contract manufacturer. Do not expand vague language into a more specific assurance than the source provides.
Separate legal requirements from voluntary programs. In the United States, dietary supplement manufacturing, packaging, labeling, and holding operations are addressed by 21 CFR Part 111. A business statement that it follows applicable requirements is not itself a government certificate. Private certification programs can assess defined facilities or systems against their criteria, while a regulator inspection is an agency activity with its own scope and classification. Build a separate evidence field for each category so they cannot be merged into one GMP badge.
Resolve the responsible facility identity
A supplement label may name a distributor or brand owner without naming the facility that manufactured the product. A company can also use several owned or contract sites. Record the label's responsible-party statement exactly and distinguish it from a separately disclosed manufacturer. For any claimed facility, capture legal name, trading name, physical address, parent organization, country, and an official establishment identifier when a public record provides one. Similar company names are not enough for a match.
Facility records are location-specific. Do not apply a certificate or inspection for one address to another plant under the same group. If a company will not identify the manufacturing site publicly, show facility undisclosed and limit verification to the claim that can actually be checked. That gap does not prove a failure, but it prevents a site-level match. Seller statements and brand customer-service replies should be dated and preserved as company-provided information rather than presented as independent records.
Read regulatory requirements from the responsible authority
Use the current regulation and regulator guidance for the applicable jurisdiction. For U.S. dietary supplements, Part 111 and FDA's small-entity guide explain responsibilities for personnel, facilities, equipment, production and process controls, holding, complaints, and records. A guide can explain that regulated firms have duties under the rule without declaring that a named facility complies. Compliance is a factual and legal status that cannot be inferred from a generic claim or from the existence of a business record.
Registration and inspection are also distinct. A facility registration can identify an establishment within a regulatory system but does not automatically document an inspection or a product-level assessment. FDA does not issue a general product approval merely because a facility is registered. Keep registration number, inspection event, inspection classification, warning letter, recall, and private certificate in separate columns. Each record has different coverage, dates, caveats, and responsible issuing body.
Check inspection information with its database caveats
Search an official regulator inspection source using the facility's legal identity and location. Record inspection dates, project area or commodity, final classification where public, and direct record link. Read the database notes before drawing any summary. FDA states that its Inspection Classification Database is not a comprehensive listing of all conducted inspections and excludes specified categories. Therefore, not located after a search is a database result, not proof that no inspection occurred.
Inspection classifications describe the agency's final classification for the relevant inspection project area and date. They should not be turned into permanent facility grades or applied to unrelated sites and products. A later inspection can have a different scope or outcome. If a warning letter or other compliance action is linked, cite the official document and its dates without extrapolating beyond the issues and entities named. If a public record has not reached a final state, do not invent an interim classification.
Verify private programs within the issuer's stated scope
When a claim says certified or audited, identify the private issuer, exact program, covered object, certificate or participant number, facility or product name, address, relevant dates, and stated scope. IAF CertSearch is used here only for an accredited management-system certificate when a matching record is available; it is not a universal directory for dietary-supplement product verification or every GMP audit program. For any other scheme, use the named issuer's own program description and record rather than treating an IAF search as a substitute.
A named example shows why the distinction matters: USP describes its Dietary Supplement Verification Program as including a manufacturing-facility audit, product-document review, laboratory testing, and continuing off-the-shelf testing. That product verification program is not interchangeable with a regulator inspection, a laboratory accreditation, or an audit-only service. Record only the elements and covered products that the issuer actually confirms. Do not apply a facility or system record to every brand made at the address without a reliable product relationship.
Present an evidence matrix instead of a merged badge
Publish separate rows for company claim, applicable regulation, disclosed facility, registration record, inspection record, official compliance action, and private certification. For each row show issuer, subject, scope, status, relevant dates, source, and match quality. A reader can then see whether GMP appears only as marketing text or is accompanied by a current, location-matched third-party record and a dated regulator inspection entry. The table should not assign a universal score from unlike evidence types.
Use precise states such as claim captured, facility identity unresolved, certificate located and address matched, inspection record located for stated date and project area, or no result in a database with stated limitations. Do not write government certified when the record is private, and do not write FDA approved from a registration or inspection entry. Recheck time-sensitive records and preserve previous dated findings. The outcome is manufacturing-document literacy, not a declaration about a product's health effects, comparative rank, or personal suitability.
- Copy the exact GMP or manufacturing claim and identify its claimant.
- Separate regulatory duty, company statement, inspection, and private certification.
- Resolve the legal facility name and physical address.
- Do not substitute a distributor or brand address for a manufacturing site.
- Read current requirements on the responsible authority's official site.
- Record inspection dates, project area, classification, and database caveats.
- Verify private certificates with the issuer, scope, address, and status.
- Publish each evidence type independently without a merged quality score.
Limitations
- A public inspection database may not contain every inspection or pending matter.
- One facility record does not automatically apply to another site or every branded product.
- A regulatory inspection and a private certification have different scopes and issuers.
- This workflow documents manufacturing claims and records without making legal or product-outcome conclusions.
