Quality documentation RFQ guide for IATF evidence, PPAP scope, CMM, X-ray, and traceability
Use this RFQ route when supplier approval depends on certificate scope, PPAP or FAI records, CMM reports, X-ray review, material records, or traceability.
This page is for procurement, SQE, and engineering buyers who need to compare supplier quality evidence before a drawing package can become a trusted quote.

Use this page as the last stop before contact
The goal is to replace vague contact intent with a quote that includes drawing/spec, material, quantity or MOQ, tooling, lead time, testing, and reply path.

What to include so the quote is real
• Part drawing or NDA-first review note with critical features, special characteristics, sealing surfaces, datums, or customer-specific approval requirements marked
• Required certification evidence: current IATF 16949 certificate, certified scope, IATF USI verification, ISO 9001 integration, or customer audit requirements
• Required approval documents: PPAP level, FAI format, PSW, dimensional report, material certificate, control plan, PFMEA, MSA, capability study, or traceability format
• Inspection records needed for quotation: CMM report, X-ray or CT review, leak-test record, sectioning, tensile test, hardness, surface finish, coating, or third-party lab report
• Program context: sample quantity, annual volume, destination, Incoterm, launch timing, customer-specific requirement, and whether records are needed for supplier approval or serial production
Commercial comparison
Questions that separate a serious quote from a placeholder quote
| Certificate scope | Ask for the current certificate, issuer, validity, site scope, and verification path. Do not treat a certificate as proof that every document applies to every project. |
|---|---|
| PPAP / FAI need | State whether the quote must include PPAP, FAI, PSW, dimensional report, material results, MSA, control plan, PFMEA, or customer-specific forms. |
| Inspection records | CMM, X-ray, CT, leak test, tensile, hardness, roughness, coating, and third-party reports should be priced and scheduled by project scope. |
| Traceability | Define heat/lot traceability, part marking, record retention, shipment document format, and whether the buyer needs serial-level tracking. |
| Best next action | Send the drawing package and documentation list so Bohua can review which records are feasible, which are standard, and which require extra sampling, timing, or third-party cost. |

Questions buyers usually ask on quote-intent pages
When should buyers use the quality documentation RFQ route?
Use it when supplier approval depends on certificate scope, IATF verification, PPAP, FAI, dimensional reports, material records, CMM, X-ray, leak-test records, traceability, or third-party testing before quotation.
What is the difference between certification evidence and project records?
Certification evidence describes the audited quality-system scope. Project records are drawing-specific documents such as dimensional reports, material certificates, CMM reports, X-ray scope, FAI, PPAP, or traceability records.
Can every RFQ include full PPAP documentation?
The PPAP scope depends on the drawing, customer requirement, launch plan, sampling method, and approval path. The RFQ should state the required PPAP level and document list before quote comparison.
What should buyers attach if they need supplier approval evidence?
Attach the drawing package, customer-specific requirement, certificate or audit checklist, PPAP or FAI expectation, inspection record list, traceability format, sample quantity, annual volume, and target approval date.
