- IATF 16949:2016 — Automotive quality management system standard; specifies PPAP (Production Part Approval Process) and corrective-action disciplines required by major automotive OEM buyers
- ISO 13485:2016 — Medical device quality system standard; mandates design controls and traceability that separate high-discipline manufacturers from commodity producers
- IPC-A-610 — Electronics assembly workmanship standard; Class 2 and 3 certifications demonstrate measurable process discipline beyond generic quality claims
- SAMR business scope and HS codes — China's entity registration and customs export records provide third-party verification of manufacturing capability and market-tier demand discipline

FAQ
Is ISO 9001 enough to confirm a quality OEM?
No. ISO 9001 is the entry floor. The signal worth weighting is the next-tier certification or documented control set matched to your product family — IATF 16949 for automotive, ISO 13485 for medical, AS9100 for aerospace, or IPC-A-610 Class 2/3 workmanship controls for electronics assembly.
How many engineers should a real OEM factory employ?
There is no universal pass/fail number. In Agence Octo observations, factories handling non-trivial OEM work often carry 6–15% engineering headcount across design, DFM, tooling, and quality. Below 3% on a non-catalog product is a caution signal, not a standalone disqualifier.
Can I trust customer references provided by the factory?
Treat them as directional. Ask each reference for tenure, current order status, and whether they re-shopped recently. Same-industry references with multi-year tenure carry more signal than generic testimonials.
