AMS supports IATF 16949 auto parts plants
AMS provides complete PPAP, CO and CQ documentation for every material lot, helping automotive component suppliers in Vietnam significantly shorten approval times from their upstream customers and maintain a quality management system compliant with IATF 16949.
For Tier 1 and Tier 2 plants, auxiliary materials such as adhesives, tapes and gaskets are often overlooked until an audit reveals a traceability gap. A single adhesive lot missing its certificates can delay an entire project by several weeks. That is why AMS has built a dedicated documentation process for its automotive customers.
What IATF 16949 requires of incoming materials
The standard requires plants to control their suppliers and ensure that materials meet statutory requirements and customer-specific requirements, with traceability down to each production lot. For chemicals, this also includes safety data sheets, restricted substance declarations and shelf-life information.
When even a minor change occurs on the material manufacturer's side, such as a change of packaging site, the component plant needs to be notified so it can re-evaluate. The distributor therefore serves as an information bridge, not merely a delivery provider.
The documentation package AMS prepares for each material code
- Certificate of origin (CO) and certificate of quality (CQ) for each imported lot.
- Technical data sheet (TDS) and safety data sheet (SDS) in both English and Vietnamese.
- RoHS and REACH declarations, plus IMDS listings upon customer request.
- Level 3 PPAP documentation prepared together with the manufacturer: test results, process flow diagram and control plan.
- Product change notifications (PCN) sent at least 90 days in advance, as committed by the manufacturer.
Approval time comparison
| Item | Compiling documents in-house | With AMS support |
|---|---|---|
| Collecting TDS, SDS, CQ | 1–2 weeks | 1–2 days |
| Preparing the PPAP package | 4–6 weeks | 2–3 weeks |
| Responding during audits | Depends on manufacturer response | AMS engineers participate directly |
Automotive customers are not just buying a tube of adhesive; they are buying the certainty that the hundredth lot is identical to the first. Documentation is how we prove it. — Quality Engineer, AMS Vietnam
Support after approval
Once a project enters mass production, AMS maintains safety stock in the Bac Ninh and Hai Phong areas, tracks shelf life on a FEFO basis and provides lot traceability reports whenever customers need to investigate an incident. Commonly used material groups include structural adhesives, formed-in-place silicone gaskets, acrylic foam tapes and thermal materials for electronic control units.
If your company is preparing for an IATF 16949 audit or needs a PPAP package for a new material, contact AMS Vietnam for engineering advice and sample documentation.
