How can I verify that an HDMI cable is really certified?

Check the label on the cable and verify the exact model through the HDMI Adopter / ATC channel.

Answer: check the certification label on the cable itself, then verify the exact model through the HDMI Adopter / ATC channel.

Ask for the certification status of that model, not of the company.
A factory can be an HDMI Adopter and still not have the specific cable certified.
Certified cables carry a certification label; uncertified ones can carry the same printed specification.

Tonetron Engineering Team· Dongguan Taitron Electronic Limited

Tonetron is the export brand of Dongguan Taitron Electronic Limited, a cable and connectivity manufacturer in Dongguan, Guangdong, China. Our engineering and QA teams write these guides from our own production and test experience — including HDMI Forum ATC confirmations (certificates 5QSIMQP4DLG, 2JCHSF3SL1X, MG3CQ3Z4BAG) and USB-IF USB4 certification testing passed under TID 6801. Our USB-IF membership has since lapsed, so that entry is no longer in the public USB-IF product search; the certificate itself is published on our credentials page. The credential you can verify yourself right now: we have been a licensed HDMI™ Adopter since June 2005 — searchable under “Dongguan Taitron” in the official HDMI™ Adopter directory.
