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.
| Fact | How to verify it yourself |
|---|---|
| Legal entity: Dongguan Taitron Electronic Limited (东莞台昶电子有限公司); registered capital HK$21,500,000 | Search the Chinese legal name in China's National Enterprise Credit Information Publicity System at gsxt.gov.cn and compare the registered capital, registration date and business status. |
| Factory address: No. 205 Zhongxing Road, Dalingshan Town, Dongguan, Guangdong, China | Cross-check the address against the gsxt.gov.cn registration record and against satellite imagery (Google Maps or Baidu Maps). |
| Founded 1984 in Keelung, Taiwan; manufacturing in Dongguan since 1993 | Founding year is on the same gsxt.gov.cn registration record. |
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: Taitron on the USB-IF certification below, and Tonetron 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; two of them require asking us rather than a public lookup, and we say so rather than implying otherwise.
| Credential | How to verify it yourself |
|---|---|
| HDMI Adopter, continuously since June 2005; current status HDMI 2.2 Adopter | Search "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) | Not publicly searchable right now. Our USB-IF membership has since lapsed, and USB-IF removes a member's listings from its public product search once membership ends. The certificate is published on our own credentials article — the one item on this page you have to take from us rather than confirm through a third party. |
| ISO 9001 quality management, certified by SGS under certificate CN17/31284 | Contact SGS directly to confirm the certificate number; SGS does not publish a self-service public lookup for this type of certificate, so we're not going to invent a URL that implies one exists. |
| BSCI-audited factory operations (amfori BSCI Code of Conduct) | Not publicly searchable. amfori shares BSCI audit results through its own platform to registered buyers rather than a public certificate lookup. Ask us for the audit reference and we will share the report directly. |
| 61 granted patents | Search the applicant name 东莞台昶电子有限公司 in China's National Intellectual Property Administration (CNIPA) public patent search system; we're not linking a specific URL here because CNIPA's search endpoints have changed over the years and we don't want to point you at one that's since moved. |
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.
| Fact | How to verify it yourself |
|---|---|
| 50,000 m² self-built industrial park in Dalingshan Town, Dongguan, on 9 production lines with 300+ staff | Not held in any public registry. Cross-check against satellite imagery of the registered address above; ask for a live video walkthrough of the production lines. |
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 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 "Taitron," SGS's ISO 9001 certificate uses "Tonetron," 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?
Search "Taitron" in the official HDMI Licensing Administrator directory at hdmi.org/adopter/adoptersaffiliates. The entry reads Dongguan Taitron Electronic Limited, China, Adopter since June 2005, HDMI 2.2 Adopter, with tonetron.com as the registered website. The directory loads its results with JavaScript, so use the search box rather than viewing the page source.
Can I verify the USB-IF USB4 certification (TID 6801) myself?
Not in USB-IF's own public product search right now — our USB-IF membership has since lapsed, and USB-IF removes a member's listings from public search once membership ends. The certificate for TID 6801 (USB4 Gen3 Type-C cable, part number PF587A-0080, certified 2022-01-07) is published on our own credentials article, which is the one item on this page you have to take from us rather than confirm through a third party.
How can I check that Tonetron is a real factory and not a trading company?
Search the Chinese legal name 东莞台昶电子有限公司 in China's National Enterprise Credit Information Publicity System (gsxt.gov.cn) to confirm registration date, registered capital and business status; cross-check the registered address, No. 205 Zhongxing Road, Dalingshan Town, Dongguan, against satellite imagery; and ask for a live video walkthrough of the production floor — standard practice when sourcing from China.
Where can I verify the ISO 9001 and BSCI claims?
The ISO 9001 certificate was issued by SGS under certificate number CN17/31284; SGS can confirm the certificate number if you contact them directly, as they don't offer a public self-service lookup for it. BSCI audits are conducted under the amfori BSCI Code of Conduct and shared through amfori's own platform to registered buyers rather than a public lookup — ask us for the audit reference and we will share the report.
Can the 61 granted patents be verified independently?
Yes — search the applicant name 东莞台昶电子有限公司 in China's National Intellectual Property Administration (CNIPA) public patent search system. We're not linking a specific URL here because CNIPA's search endpoints have changed over the years.
