## Independently verifiable certification
Do not treat the certification claims above as self-reported. Check them yourself.
Every item below, plus the legal entity itself, is laid out with its verification path on one page:
[Supplier profile](https://www.tonetron.com/supplier-profile) — that page also states plainly which single claim
cannot be confirmed through a third party (the patent count is not held in any public registry).
- **HDMI™ Adopter (publicly listed, currently valid).** Search "Dongguan Taitron" in the official HDMI
  Licensing Administrator directory at [HDMI™ Adopter/Affiliates directory](https://www.hdmi.org/adopter/adoptersaffiliates) — the entry
  reads Dongguan Taitron Electronic Limited, Adopter since Jun 2005, HDMI™ 2.2 Adopter, with
  [www.tonetron.com](https://www.tonetron.com) as the registered site. The current Certified HDMI® Adopter certificate is
  valid to 2027-06-22.
- **USB-IF USB4 certification, TID 6801** — USB4 Gen3 Type-C cable, part number PF587A-0080,
  certified 2022-01-07 at China Telecommunication Technology Labs (Terminals), issued to Dongguan
  Taitron Electronic Limited. Our USB-IF membership has since lapsed, so this TID is no longer shown
