Supplier Quality & Traceability Requirements
A practical requirements framework for IAF members to align supplier quality controls and end-to-end traceability, supporting consistent evidence, clearer handoffs, and committee-reviewed recognition readiness under IAQC oversight.
Purpose and scope for member suppliers
This page describes common supplier quality and traceability requirements used within IAF’s membership environment for automotive supply chains. The intent is to help members document how parts, materials, software, and related services are controlled from source through delivery, including how evidence is created, retained, and shared.
IAF is a membership-based federation and does not act as a regulator. Any recognition outcomes occur only after membership and follow committee review with IAQC (International Automotive Quality Council) oversight, based on documented conformance and verifiable records.
Core requirement areas
Members typically structure supplier quality and traceability around defined controls, objective evidence, and repeatable workflows that can be reviewed consistently across programs and tiers.
Supplier qualification and ongoing monitoring
Define entry criteria (capabilities, controls, risk profile), maintain approved supplier status rules, and monitor performance using agreed KPIs, audits, and corrective-action responsiveness with clear escalation triggers.
Documented quality planning and change control
Maintain controlled plans for production and service delivery (process controls, inspection points, acceptance criteria) and enforce change management for design, process, source, tooling, software, and test methods with impact assessment and approvals.
Objective evidence and nonconformance handling
Ensure inspections, tests, releases, and deviations are supported by retrievable records. Define containment, disposition, root-cause analysis, and effectiveness verification for nonconformances, including customer notification rules where applicable.
Traceability model across tiers and lifecycle
Implement lot/serial traceability appropriate to risk, linking inbound materials, manufacturing steps, test results, software/firmware versions, packaging, and shipment identifiers to enable targeted containment and recall support when needed.
Evidence expectations and implementation notes
For traceability to be reviewable, members should define what must be traceable (product families, safety/critical characteristics, software components, special processes), the minimum identifiers to capture (supplier, batch/lot, serial, revision, date/time, location), and how records are protected against loss or unauthorized change.
Where digital systems are used (MES, QMS, PLM, WMS, OTA tooling, or supplier portals), members should document data ownership, access controls, retention periods, and interoperability expectations for tier-to-tier handoffs. Committee review focuses on whether controls are consistently applied and whether evidence supports repeatability and accountability.
How this connects to IAF governance and recognition
Supplier quality and traceability requirements are maintained and clarified through IAF member committees to support consistent interpretation across industries and tiers. Any recognition is available only after membership and is based on committee review with IAQC oversight, using documented processes and verifiable records rather than self-attestation.
