ISO 9001
Quality management
Confirm certificate holder, scope, validity, and manufacturing site.
Certification verification
A certificate logo is not enough. Check holder, scope, product, site, and validity.
KeelGauge treats supplier certificates as evidence to verify, not decorative platform claims. Buyers can request document checks before quotation or order confirmation.
No certificate borrowing
A matched supplier must support its own applicable manufacturing scope. Platform pages do not imply that KeelGauge itself holds manufacturer certificates.
