OEM Requirements
Automotive OEMs requiring IMDS submissions
Material composition must be declared to 1-gram resolution
PPAP approval rate without accepted IMDS data
Regulation Overview
IMDS is the automotive industry's global material data system and the backbone of substance compliance for vehicle manufacturing. For supply chain teams, the primary obligation is creating and submitting Material Data Sheets (MDS) that declare 100% of the material composition for every part, component, and assembly delivered to participating OEMs.
The system now includes 62+ global automotive OEMs, from the original consortium of Audi, BMW, Daimler, Ford, Opel, Porsche, VW, and Volvo to nearly every major vehicle manufacturer worldwide. IMDS has become a mandatory prerequisite for the Production Part Approval Process (PPAP)—without an accepted MDS, suppliers cannot achieve PPAP approval and cannot supply parts.
IMDS compliance requires substance-level data—CAS numbers, weight percentages, and material classifications—for every material in every part. The system screens declarations against the Global Automotive Declarable Substance List (GADSL), which categorizes substances as prohibited, declarable, or declarable/prohibited. When GADSL updates occur or new regulatory requirements emerge under REACH or RoHS, your entire MDS portfolio requires reassessment.
Tier 1 automotive suppliers delivering parts directly to OEMs
Tier 2 and Tier 3 suppliers providing components and materials to higher-tier customers
Raw material and chemical suppliers providing formulations to the automotive supply chain
Non-automotive companies entering the automotive supply chain for the first time
Companies assembling complex modules from multiple sub-component suppliers
Distributors supplying parts or materials that become part of vehicles
Key Thresholds
Your OEM customer requires an MDS for a complex assembly containing 45 components from 20 suppliers. Supplier 1 has never heard of IMDS. Supplier 2 submitted an MDS two years ago but it was rejected. Supplier 3 provides raw materials with confidential formulations. Your team spends weeks training suppliers, reformatting data, and chasing incomplete submissions—delaying PPAP approval by months.
You submit an MDS to your OEM customer. Rejected: wildcard substance exceeds 10% limit. You fix it. Rejected again: GADSL substance not individually declared. You correct. Rejected a third time: weight tolerance outside Recommendation 001 range. Each rejection cycle takes days. Meanwhile, production timelines slip and customer confidence drops.
IMDS requires full substance disclosure to 1-gram resolution—not summaries, not approximations. A Tier 3 supplier provides a safety data sheet listing only hazardous ingredients. That covers 40% of the formulation. The remaining 60% is undeclared. Without substance-level BOM mapping, your MDS is incomplete and will be rejected on submission.
GADSL updates reclassify substances annually—moving them from declarable to prohibited, adding new substances, or changing threshold requirements. Every update requires screening your entire MDS portfolio against the revised list. With thousands of active MDS records and hundreds of supplier materials, manual screening across every submission becomes unsustainable.

Frequently Asked Questions
What suppliers are required to submit IMDS data?
Every supplier delivering parts, components, or materials that end up in a vehicle manufactured by a participating OEM must submit an MDS through IMDS. This includes Tier 1 through Tier N suppliers—anyone in the supply chain contributing material to a finished vehicle. PPAP approval cannot be granted without accepted IMDS data. CORA automates the collection of substance data from suppliers at every tier, ensuring complete material declarations reach your compliance team regardless of supplier IMDS experience.
What happens when an MDS is rejected by an OEM?
OEM rejection means the MDS does not meet IMDS Recommendation standards, GADSL screening requirements, or OEM-specific substance rules. Common rejection reasons include wildcard substance violations, incomplete composition declarations, and undeclared GADSL substances. Each rejection delays PPAP approval and production timelines. Certivo's BOM substance and threshold management pre-validates material data against Recommendation 001 and GADSL before submission, reducing rejection rates and accelerating PPAP cycles.
How does Certivo handle GADSL updates and substance reclassifications?
Certivo maintains continuous sync with the GADSL, incorporating substance reclassifications within days of publication. When substances are reclassified—from declarable to prohibited, or newly added—CORA reassesses your entire material portfolio and alerts you to affected MDS records, triggering the appropriate update workflows automatically through regulatory intelligence and horizon scanning.
What declaration formats does Certivo accept from automotive suppliers?
Certivo accepts any format: PDF declarations, Excel spreadsheets, safety data sheets, IPC-1752, existing IMDS exports, and freeform responses. CORA extracts substance data to CAS number precision regardless of format or language through AI document parsing and certificate validation, eliminating the need to standardize supplier inputs before processing.
Does Certivo support IMDS alongside REACH, RoHS, and CAMDS requirements?
Yes. Certivo validates one supplier submission against GADSL, REACH SVHCs, RoHS restricted substances, ELV Annex II, and PFAS requirements simultaneously through multi-tier supply chain transparency. The same material data supports both IMDS and CAMDS submission preparation—eliminating duplicate supplier collection campaigns and enabling integrated PLM ERP compliance thread across global OEM requirements.
