Scope boundaries we publish before you specify us
Certificates are held by the manufacturing entity
IATF 16949:2016 and ISO 9001:2015 are registered to Dongguan Linkssor Automotive Wiring Harness Co., Ltd. — the plant, not a trading company.
IATF 16949 design responsibility (Clause 8.3) is excluded
The certified scope is manufacturing of wire harness. A design-responsible programme is delivered through our Shenzhen engineering entity and needs a separate contractual structure.
Engineering and simulation sit with the Shenzhen entity
Shenzhen Linkssor Technology Co., Ltd. holds three registered software copyrights covering harness stress simulation, machine-vision sequence verification and process parameter control, plus the waterproof connector patent.
Documentation is issued per shipment
Certificate of conformity, dimensional and inspection reports, electrical test records, crimp micro-section analysis for the terminals in use, and material declarations per part number.
FAQ
Which legal entity holds the IATF 16949 certificate?
Dongguan Linkssor Automotive Wiring Harness Co., Ltd. — the manufacturing entity. The Shenzhen entity, Shenzhen Linkssor Technology Co., Ltd., holds the software copyrights, the patent and the National Sci-Tech SME registration.
Does the IATF certificate cover design?
No. The certified scope is manufacturing of wire harness and explicitly excludes Product Design under Clause 8.3. We disclose this because buyers need to know exactly which scope is certified.
Can the certificates be verified independently?
Yes. IATF certificate validity is verified through the IATF database using certificate number 0597346 and IATF USI L5MNF5, and through the CNCA website. The ISO 9001 certificate is verifiable at cacq.org.cn using registration CACQ22Q00816R1.
Do you hold two separate factory addresses?
The certificate records two Dongguan Chang'an addresses — No. 19 Hexing Road (Building 1, Room 201) and No. 13 Shayong Road (Floor 3). Both are used for harness production; a customer audit plan should confirm which site builds the part.
Need a certificate verification or an audit pack?
Send the programme requirements and we will return the certificate set, scope statement and any declarations your supplier qualification process needs.
