Substance entries tracked under GADSL (2026)
Declaration threshold by weight of homogeneous material
IMDS material disclosure required for every part supplied
Regulation Overview
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).
When GADSL updates or new REACH SVHCs are published, existing Material Data Sheets must be reassessed and resubmitted. Supplement 1 of VW 91101 contains proprietary VW Group material bans that go beyond GADSL and global regulations, requiring specialized substance reporting solutions.
Direct (Tier 1) suppliers to any Volkswagen Group brand worldwide
Sub-tier suppliers whose materials or substances remain in the finished vehicle
Suppliers of operating fluids, coolants, lubricants, and process materials
Suppliers of aftermarket and replacement parts for VW Group vehicles
Contract manufacturers producing components under VW specifications
Any supplier whose parts are exported to EU, China, or other regulated markets
Key Thresholds
GADSL updates annually in March, and IMDS implements changes immediately. Every active Material Data Sheet must be reviewed for reclassified substances—but VW 91101 Supplement 1 adds proprietary bans on top. Your team must track two moving targets simultaneously across thousands of parts while maintaining continuous compliance monitoring and audit readiness.
IMDS 14.3 now auto-rejects submissions with unclassified materials, wildcard-hidden GADSL substances, or improper VDA classifications. Volkswagen enforces these rules strictly per VW 91101. One rejected MDS cascades into PPAP delays, production holds, and line-down risk. Without BOM-level compliance intelligence, teams cannot catch errors before submission.
VW 91101 applies the 0.1% declaration threshold at the homogeneous material level—not component level. A trace additive in a coating, a plasticizer in a seal, or an impurity in a solder alloy can trigger full declaration obligations. Without substance-level BOM substance and threshold management, hidden exposures go undetected until Volkswagen rejects the submission.
Volkswagen requires complete material traceability from raw material to finished part. Sub-tier suppliers must provide substance data that rolls up into Tier 1 IMDS submissions. When suppliers operate across multiple OEMs—each with distinct requirements—maintaining multi-tier supply chain transparency becomes unsustainable through manual processes and spreadsheet-based hazardous substance tracking.

From Manual Compilation to Automated Validation
CORA extracts substance data and validates against GADSL and VW 91101 Supplement 1 automatically. Your team focuses on exceptions and engineering decisions—not manual data entry into IMDS through AI-native compliance automation.
VW 91101 Documentation Acceleration
Generate complete, validated substance reports structured for IMDS submission in hours—not the weeks of manual compilation and supplier chasing that BOM substance and threshold management traditionally requires.
Continuous Compliance Monitoring and Audit Readiness
When GADSL reclassifies substances or VW updates Supplement 1, Certivo reassesses your portfolio instantly. Know which parts are affected before Volkswagen rejects your IMDS submission—through integrated PLM ERP compliance thread connectivity.
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.
