Supplier Profile — Verifiable Facts

This page lists what we can say about Tonetron with a source a buyer can check independently. Most of the facts below can be confirmed in a public registry or directory without contacting us; the ones that can't are marked as such rather than presented as if they could.

Legal entity and history

Tonetron is the export brand of Dongguan Taitron Electronic Limited (东莞台昶电子有限公司), founded in 1984 in Keelung, Taiwan, and relocated in 1993 to a self-built industrial park in Dalingshan Town, Dongguan, Guangdong, China.

Separately request documents linking the company to its current production site, and cross-check them by an on-site visit or live video. Maps and satellite imagery help locate the site; by themselves they do not establish who currently operates it or whether production is taking place.
Founded 1984 in Keelung, Taiwan; manufacturing in Dongguan since 1993The 1984 founding and 1993 relocation are company-reported history; ask us for the supporting historical documents. Check the Chinese legal entity’s registration date separately at gsxt.gov.cn; do not infer it from these dates.

Two names, one company

The same Chinese legal entity, 东莞台昶电子有限公司, has been transliterated two ways on certificates issued by different bodies: Dongguan Taitron Electronic Limited on the USB-IF certification below, and Dongguan Tonetron Electronic Limited on the SGS ISO 9001 certificate below. A related site the same legal entity operates, tonetronsource.com, uses a third variant, "Dongguan Taitron Electronics Limited." All three refer to this one company — if a directory search under one name returns nothing, search the others.

Certifications and test records

Each certification below is listed with the body that issued it and how directly you can check it.

CredentialHow to verify it yourself
HDMI™ Adopter, continuously since June 2005; current status HDMI™ 2.2 AdopterSearch "Dongguan Taitron" in the official HDMI Licensing Administrator directory at hdmi.org/adopter/adoptersaffiliates. The entry reads Dongguan Taitron Electronic Limited, China, Adopter since Jun 2005, HDMI™ 2.2 Adopter, with tonetron.com as the registered website. (The directory loads its list with JavaScript — use the search box rather than a page-source view.)
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)Check the certification-date filter. USB-IF's public product search defaults to products certified within the last two years. For the 2022 certificate, adjust the date filter and search TID 6801. A missing search result alone does not establish current membership or certification status; confirm current listing and compliance with USB-IF or the manufacturer. The certificate is published on our own credentials article.
ISO 9001 quality management, certified by SGS under certificate CN17/31284Use the SGS Certified Client Directory to search certificate CN17/31284, or search by the full company name and location shown on the certificate. Check the holder, site address, certification scope and current status. If you cannot verify the record, contact SGS through its official channels; do not infer validity or invalidity from a missing result alone. Request a copy of the certificate, check its issue date and validity period, and cross-check these against the current SGS record.
BSCI-audited factory operations (amfori BSCI Code of Conduct)amfori BSCI is a social responsibility audit system, not a certification. Ask us for the audit reference, audited site and audit date. amfori members and their audited suppliers can review full reports on the amfori Sustainability Platform, subject to the relevant business relationship and account permissions.
61 granted patents (company-reported)For the company-reported 61 granted patents, request the patent list and application or patent numbers. Start at the CNIPA official website and use the patent search and patent examination information services. Search the applicant or patentee name 东莞台昶电子有限公司 and check each number, grant announcement and current legal status. The reported count does not establish that all 61 are currently in force; a missing search result alone does not establish invalidity.

Factory scale

These figures are what a buyer would use to distinguish a manufacturer from a trading company. The registered capital and address above are checkable in a public registry; the physical scale below is not held in any public database we're aware of, so we suggest checking it against satellite imagery and asking for a live video walkthrough — standard practice when sourcing from China, and one we support.

FactHow to verify it yourself
50,000 m² self-built industrial park in Dalingshan Town, Dongguan, on 9 production lines with 300+ staffCompany-reported figures. Satellite imagery can help check the site location, but does not establish the stated area, production-line count or staff count. Ask for supporting documents and an on-site or live-video factory walkthrough to cross-check these figures.

Monthly capacity (1,000,000+ cables) and export reach (40+ countries) are figures we report about our own operations rather than facts held in a public registry. The concrete, requestable evidence is recent export shipping documents, which we provide on request.

Frequently asked questions

Is "Taitron" the same company as "Tonetron"?

Yes — both are Dongguan Taitron Electronic Limited (not Taitron Components Inc., an unrelated US company). Both names transliterate the same Chinese legal entity, 东莞台昶电子有限公司 (Dongguan Taitron Electronic Limited): USB-IF's own certification records use "Dongguan Taitron Electronic Limited," SGS's ISO 9001 certificate uses "Dongguan Tonetron Electronic Limited," and the company's own tonetronsource.com site uses "Dongguan Taitron Electronics Limited." If a directory search under one name returns nothing, search the others.

How can I verify Tonetron's HDMI™ Adopter status without contacting the company?

Can I verify the USB-IF USB4 certification (TID 6801) myself?

A missing search result alone does not establish current membership or certification status; confirm current listing and compliance with USB-IF or the manufacturer.

Where can I verify the ISO 9001 and BSCI claims?

Can the 61 granted patents be verified independently?

For the company-reported 61 granted patents, request the patent list and application or patent numbers. Start at the CNIPA official website and use the patent search and patent examination information services. Search the applicant or patentee name 东莞台昶电子有限公司 and check each number, grant announcement and current legal status. The reported count does not establish that all 61 are currently in force; a missing search result alone does not establish invalidity.
