### Customer & Industry Requirements

###### Environmental Standard for Products — Material Suitability (Avoidance of Hazardous Substances)

## Volkswagen Rejects Non-Compliant IMDS Submissions Automatically. Can Your Substance Data Survive OEM Scrutiny?

VW 91101 compliance requires substance-level material declarations across your entire supply chain—validated against the GADSL, REACH SVHCs, and Volkswagen Group-specific bans. IMDS submissions must be accurate to CAS number level. Non-compliant Material Data Sheets trigger automatic rejection. VW 91101 Supplement 1 adds proprietary restrictions beyond global regulations and is updated regularly without advance notice.

Certivo automates substance tracking from supplier declaration to OEM-ready IMDS validation.

## What Is VW 91101?

VW 91101 is Volkswagen Group's environmental standard governing the avoidance of hazardous substances in vehicle parts, materials, and operating fluids. It is the cornerstone of VW 91101 compliance for every supplier in the Volkswagen supply chain—spanning VW, Audi, Porsche, SEAT, ŠKODA, Bentley, Lamborghini, and all affiliated brands. The standard mandates compliance with global chemical regulations, including EU REACH, the EU End-of-Life Vehicles (ELV) Directive, and the CLP Regulation, while imposing additional Volkswagen Group-specific substance bans that exceed regulatory minimums.

VW 91101 compliance requires substance-level material data—CAS numbers, concentrations, and VDA material classifications—for every part entering the Volkswagen supply chain. The standard references the GADSL as the baseline for declarable and prohibited substances and requires all substance data to be submitted through the International Material Data System (IMDS).

## Frequently Asked Questions

**What products and companies are subject to VW 91101 compliance obligations?**

Any company supplying parts, materials, or operating fluids to a Volkswagen Group brand—including VW, Audi, Porsche, ŠKODA, SEAT, Bentley, and Lamborghini—must comply with VW 91101. The standard applies to all substances in vehicle components, aftermarket parts, and process materials. Compliance requires 100% substance disclosure through IMDS at CAS number level, validated against GADSL and VW 91101 Supplement 1. Certivo automates this entire validation workflow.

**What happens if a supplier fails VW 91101 compliance?**

Volkswagen auto-rejects non-compliant IMDS submissions under IMDS 14.3 validation rules enforced per VW 91101. Rejected Material Data Sheets block PPAP approval, delay production launches, and can result in supplier scorecarding downgrades. Repeated non-compliance risks disqualification from future VW Group programs. CORA's pre-submission validation catches errors before they reach Volkswagen.

**How does Certivo track updates to GADSL and VW 91101 Supplement 1?**

Certivo maintains continuous sync with the GADSL, incorporating substance reclassifications within days of the annual March update and any interim revisions. When substances are reclassified or VW 91101 Supplement 1 is revised, CORA reassesses your entire portfolio and alerts you to affected parts—triggering the appropriate IMDS revision and customer notification workflows automatically.

**What declaration formats does Certivo accept from suppliers for VW 91101?**

Certivo accepts any format: PDF declarations, Excel spreadsheets, IMDS exports, IPC-1752, XML files, and freeform responses. CORA extracts substance data regardless of format or language through AI document parsing and certificate validation, eliminating the need to standardize inputs across your multi-tier supply chain. This format-agnostic approach is critical for managing multi-tier supply chain transparency.

**Does Certivo validate against VW 91101 alongside REACH, RoHS, and PFAS regulations?**

Yes. Certivo validates a single supplier submission against VW 91101, GADSL, EU REACH SVHCs, RoHS heavy metals, TSCA, Prop 65, and emerging PFAS restrictions simultaneously. This eliminates duplicate collection campaigns and provides a centralized compliance data backbone across all applicable frameworks—giving compliance teams a single source of truth for OEM qualification and regulatory readiness.
