IMDS: material traceability for automotive
IMDS (International Material Data System) is the mandatory global system for the automotive industry through which Tier 1 and Tier 2 suppliers report the exact material composition of every component they deliver to an OEM — to comply with regulations like REACH and RoHS and to give the OEM full traceability of what's in every car it sells.
Why IMDS isn't optional
IMDS has been managed by DXC Technology since 2000 and is mandatory for any supplier delivering to a European OEM (VW, BMW, Mercedes, Stellantis, Renault) and many Japanese, Korean and American OEMs. Without up-to-date IMDS, orders stop.
Its complexity lies in depth: every component can have dozens of sub-components, each with its exact material composition. A small cable carries info on copper + PVC + additives. And all of that must be reported and maintained when the formulation changes.
IMDS is also the foundation of REACH (European chemical substances regulation) and RoHS (Restriction of Hazardous Substances) compliance. If your plastics supplier changes an additive without telling you, you automatically fall into non-compliance.
iLEAN doesn't replace the method — it brings it into the 21st century.
Every Lean methodology was born to solve an information problem: where stock is, which machine is failing, what changed shift-to-shift. When information is paper, methods are rituals. When it's live data, they become the actual engine of the plant.
Classical method tells you what to measure. The IRIS system guarantees the measurement reaches whoever decides, the moment they decide — without anyone typing it in.
The three capture layers applied: Connect (photo, voice, email, WhatsApp), Edge (computer vision on the line) and Integrations (ERP/MES/SCADA/PLC). On top of that unified information, specialized agents serve the exact context to each person on the floor.
Classical IMDS vs. automated IMDS
| Aspect | Classical IMDS | IMDS with iLEAN |
|---|---|---|
| Data collection | Excel with each supplier | Auto-pull from ERP + digital form to supplier |
| Upload to IMDS system | Manual, by IMDS user | Auto-upload with prior validation |
| Update on change | Only when someone finds out | Alarm when there's a change at any level |
| REACH/RoHS verification | Periodic manual audit | Continuous, instant alert if banned substance enters |
| OEM audit | Panic days before | Instant on-demand report |
What people ask about IMDS
What is IMDS and why is it mandatory in automotive?
IMDS (International Material Data System) is the global database where Tier 1 and Tier 2 suppliers report the exact composition of each automotive component. It's mandatory because OEMs require it contractually and because it underpins REACH and RoHS compliance — without current IMDS, no delivery.
What's the difference between IMDS and CAMDS (China)?
IMDS: global standard managed by DXC from Europe. CAMDS: Chinese equivalent, managed by CATARC, mandatory for selling to Chinese OEMs (BYD, Geely, SAIC). Plants exporting to China manage both in parallel — iLEAN syncs them.
How does iLEAN automate IMDS reporting without Excel?
iLEAN extracts information from your ERP/PLM, completes the material hierarchy by asking your suppliers through their usual channels, validates coherence, and uploads to the DXC IMDS platform via API. Your IMDS operator just reviews and approves.
Do I need IMDS only for specific OEMs or for all of them?
For all European OEMs and most modern global OEMs. Exceptions are very specific OEMs or vehicles not homologated for Europe. If in doubt: if you deliver to a Tier 1 that delivers to a European OEM, you need IMDS.
What happens if an IMDS data point is wrong and the OEM catches it?
Serious consequences: batch rejection, loss of PPAP homologation, contractual fines, and reputational drop in OEM supplier ranking. That's why reporting automation (vs. manual Excel) dramatically reduces risk.
