Published by QA Rating

Every fact about a company comes from a listed source. A field without a source stays empty. A certificate counts as confirmed only when a registry, certificate or auditor report backs it; a certificate the company only claims about itself is published separately, under that label. Vendors can request a correction at hello@qa-rating.com. A correction is applied when it comes with a public source. Last checked on September 3, 2026.
