PPAP Documentation from
Verified Vietnam Factories
Dewin manages the full Production Part Approval Process for 179+ audited Vietnamese suppliers — so you get documentation-ready parts with zero overseas chasing.
The PPAP Gap Problem in Overseas Sourcing
Most buyers who source overseas know they should require PPAP — but in practice, getting a complete, accurate PPAP package from an overseas factory is extremely difficult.
Factories may not understand what's required. Documentation is incomplete, translated poorly, or references the wrong revision. Dimensional results are generated by the factory without independent verification. Material certs can't be traced to the actual lot.
The result: buyers either skip PPAP and accept quality risk, or they spend months back-and-forth to get a usable package.
Dewin solves this. Our on-the-ground team acts as your quality representative inside the Vietnam factory — managing PPAP from first article to PSW sign-off.

All 18 PPAP Elements — Dewin's Role
Our team handles or reviews each of the 18 AIAG PPAP elements at the Vietnam factory, then compiles and submits the package to you.
| # | PPAP Element | Dewin's On-Ground Role |
|---|---|---|
| 1 | Design Records | Confirm customer drawing revision matches factory's working copy |
| 2 | Engineering Change Docs | Track and document any ECNs before PPAP submission |
| 3 | Customer Engineering Approval | Facilitate buyer sign-off on any design deviations |
| 4 | Design FMEA | Review factory DFMEA against customer drawing criticalities |
| 5 | Process Flow Diagram | Verify process flow matches actual factory sequence during audit visit |

| 8 | Measurement System Analysis | Document calibration status of CMM/VMM/gauges used in dimensional study |
| 9 | Dimensional Results | Conduct or witness first-article balloon check at factory (CMM or VMM); photograph all results |
| 10 | Material / Performance Test Results | Collect mill certs, material COC, hardness/tensile test reports from factory or 3rd-party lab |
| 11 | Initial Process Studies | Assist factory in running Cpk/Ppk analysis on critical characteristics (target Cpk ≥ 1.67) |
| 12 | Qualified Laboratory Docs | Verify 3rd-party lab accreditation certificates if external testing used |
| 13 | Appearance Approval Report | Coordinate visual standard approval for color/texture/surface parts |
| 14 | Sample Production Parts | Confirm parts were made from production tooling and process — not prototype |
| 15 | Master Sample | Retain master sample at factory; ship customer-retained sample with PPAP package |
| 16 | Checking Aids | Document all gauges and fixtures used for production inspection; calibration status confirmed |

Inspection Equipment in Our Factory Network
PPAP requires documented measurement capability. During our Dolphin Audit visits, we photograph and record the inspection equipment in each factory. Here's what our network has.
CMM (Coordinate Measuring Machine)
3D dimensional measurement, GD&T callouts, Cpk data, FAI reports
2D VMM (Video Measuring Machine)
Non-contact optical measurement, quick dimensional results, ideal for small precision parts
Hardness Tester
Rockwell / Brinell hardness verification for material cert corroboration
Color Comparison Machine
L*a*b* colorimetry, delta-E measurement for AAR (Element 13) on appearance parts
Calibrated Hand Gauges
Micrometers, calipers, pin gauges, thread gauges — documented calibration records for MSA
3rd-Party Test Labs
Material testing (tensile, impact, chemical analysis), accredited per ISO 17025 for Element 12
PPAP + Country-of-Origin: Vietnam's FTA Advantage
Beyond PPAP quality documentation, Dewin ensures every shipment includes proper Vietnam country-of-origin documentation — enabling buyers to access 16+ Free Trade Agreements.
COO Documentation We Provide
- ✓ Certificate of Origin (CO Form B / general CO) — issued through Vietnam's Ministry of Industry and Trade (MOIT)
- ✓ Manufacturer's Declaration — signed document from the factory confirming Vietnam-origin manufacture
- ✓ Production Records — evidence of substantial transformation in Vietnam (for US customs)
- ✓ PPAP PSW with Vietnam factory details — legal documentation confirming manufacturer identity and location
PPAP Vietnam FAQ
Can Vietnam factories produce full PPAP documentation?
Yes. Vietnam has a growing base of factories — particularly in automotive supply chains — that are experienced in PPAP documentation. Dewin's audited network includes factories capable of providing Level 1–5 PPAP packages including dimensional results, material certifications, FMEAs, control plans, process capability studies, and Part Submission Warrants. Our on-ground team reviews every package before it reaches the buyer.
How does the Dolphin Audit relate to PPAP?
Dewin's 50-point Dolphin Audit is a factory-level quality assessment that includes verification of the factory's quality management systems — including whether they have PPAP experience, documented process controls, inspection equipment (CMM, VMM, gauges), and calibration records. A factory that scores well on the Dolphin Audit's Quality pillar is a strong candidate for PPAP-capable production. PPAP then documents part-specific approval.
What inspection equipment do Vietnam PPAP factories have?
Dewin's audited network includes factories with CMM (Coordinate Measuring Machines), 2D VMM (Video Measuring Machines), hardness testers, color comparison machines, and calibrated hand gauges. For PPAP Measurement System Analysis (Element 8), these instruments are documented with calibration certificates. We photograph all measurement equipment during our Dolphin Audit visits.
How does Dewin handle PPAP documentation logistics across Vietnam?
Dewin's on-the-ground team visits Vietnam factories to conduct first-article inspections, photograph and document measurement results, collect material certificates, and review process documentation. Our team compiles the PPAP package and submits it to the buyer on behalf of the factory — bridging the communication and documentation gap that often makes overseas PPAP impractical.
Which industries require PPAP from Vietnam suppliers?
PPAP originated in automotive manufacturing (AIAG APQP) but is now required or strongly preferred in industrial machinery, medical devices, aerospace, and consumer electronics. Any US OEM or Tier 1 manufacturer that follows IATF 16949, ISO 9001, or AS9100 quality management standards will typically require PPAP from new suppliers, including those in Vietnam.
