Substance control tiers—Prohibited, Restricted, Declarable
Reporting threshold for GADSL declarable substances
IMDS data entry required for all newly adopted parts
Regulation Overview
Distributed via Toyota Supplier Portal; not publicly available
Toyota TSZ0001G is Toyota Motor Corporation's proprietary engineering standard governing the control of Substances of Environmental Concern (SOC) in vehicle parts, accessories, and raw materials. It is the cornerstone of Toyota's chemical compliance framework and a mandatory requirement for every supplier in the Toyota global supply chain. TSZ0001G classifies substances into three tiers—Prohibited, Restricted, and Declarable—with specific thresholds, application exemptions, and reporting obligations for each.
The standard references the Global Automotive Declarable Substance List (GADSL), the EU End-of-Life Vehicle (ELV) Directive, REACH SVHC requirements, and EU RoHS restrictions, while imposing additional Toyota-specific prohibitions. Suppliers must report full material composition through the International Material Data System (IMDS) at CAS number precision.
When Toyota revises TSZ0001G to add or reclassify substances, all affected parts require reassessment and updated IMDS submissions. Non-compliance can result in part rejection, supplier scorecarding penalties, and loss of Toyota business.
Tier 1 suppliers delivering parts, accessories, or raw materials directly to Toyota
Sub-tier suppliers (Tier 2+) whose materials are incorporated into Toyota-bound components
Raw material and chemical suppliers providing inputs to Toyota part manufacturers
Packaging material suppliers delivering to Toyota plants or logistics centers
Service parts and aftermarket accessory suppliers in the Toyota supply chain
Non-Japanese suppliers exporting components to Toyota plants globally
Key Thresholds
Toyota revises TSZ0001G periodically, adding or reclassifying substances without a fixed schedule. Each revision triggers reassessment of thousands of parts—but your existing IMDS data sheets reference the prior revision. Your team must identify every affected part, verify substance content against new thresholds, and resubmit updated IMDS entries before Toyota's deadline. Without centralized compliance data, the revision response becomes a multi-month fire drill.
Toyota requires 100% IMDS coverage for all newly adopted parts at CAS number precision. Supplier 1 sends a PDF in Japanese. Supplier 2 provides an Excel file missing CAS numbers. Supplier 3 uses a proprietary template. Your compliance team manually re-enters every data point into IMDS—one substance at a time. A single part with 40 materials takes hours. Multiply across hundreds of parts at PPAP, and BOM-level compliance intelligence becomes impossible to maintain.
TSZ0001G applies thresholds at the homogeneous material level, not the part level. A connector plating containing 1,200 ppm lead triggers non-compliance even though the connector represents 0.003% of vehicle weight. Without BOM substance and threshold management that maps substances to individual materials within each component, you cannot identify exposure until Toyota flags the rejection.
TSZ0001G references GADSL, ELV, REACH, and RoHS simultaneously—but each framework has different substance lists, thresholds, and reporting formats. A substance may be declarable under GADSL, restricted under TSZ0001G Table 2, and an SVHC under REACH. Without automated multi-framework validation from a single supplier submission, your team maintains parallel spreadsheets and risks conflicting declarations.

From Manual IMDS Entry to Exception Management
CORA extracts substance data automatically from any supplier format. Your team focuses on exceptions requiring human judgment—not re-keying CAS numbers into IMDS from PDF declarations. AI-native compliance automation replaces manual hazardous substance tracking.
Toyota Audit Response Acceleration
Generate complete, audit-ready Toyota compliance packages in hours—not the 4–6 weeks of manual compilation across supplier emails, spreadsheets, and IMDS screenshots.
Proactive Toyota TSZ0001G Compliance Monitoring
When Toyota revises TSZ0001G or GADSL updates substance classifications, Certivo reassesses your portfolio instantly. Know which parts are affected before Toyota's quality audit team escalates.
Frequently Asked Questions
What products and companies are subject to Toyota TSZ0001G obligations?
Every supplier delivering vehicle parts, accessories, raw materials, or packaging materials to Toyota Motor Corporation or its affiliated manufacturers globally must comply with TSZ0001G. The standard applies to all materials in the delivered state, covering Prohibited, Restricted, and Declarable substance categories. Tier 2+ suppliers are equally affected because their material composition flows into Tier 1 IMDS submissions. Certivo's multi-tier supply chain transparency ensures substance data is captured and validated at every level, eliminating gaps in your Toyota SOC compliance chain.
What happens if a supplier fails to comply with TSZ0001G?
Non-compliance with TSZ0001G can result in IMDS data sheet rejection, part rejection at PPAP, supplier scorecarding penalties, and escalation to Toyota's quality division. Repeated non-compliance risks loss of Toyota business. CORA's automated supplier data collection and AI document parsing ensure declarations are complete and accurate before submission, reducing IMDS rejection rates from double digits to under 3%.
How does Certivo track updates to TSZ0001G and GADSL?
Certivo maintains continuous sync with GADSL updates—which occur annually with mid-year revisions—and monitors TSZ0001G revision notices. When substances are added, reclassified, or threshold-tightened, CORA reassesses your entire portfolio and alerts you to affected parts, triggering the appropriate IMDS rework and supplier re-engagement workflows automatically. This regulatory intelligence and horizon scanning ensures you are always aligned with Toyota's current requirements.
What declaration formats does Certivo accept from automotive suppliers?
Certivo accepts any format: PDF declarations, Excel spreadsheets, IPC-1752, IMDS exports, XML files, and freeform responses in any language including Japanese, German, Chinese, and Korean. CORA extracts substance data regardless of format or language through AI document parsing and certificate validation, eliminating the need to standardize supplier inputs across your global supply chain.
Does Certivo support TSZ0001G alongside REACH, RoHS, GADSL, and PFAS compliance?
Yes. Certivo validates a single supplier submission against TSZ0001G, GADSL, REACH, EU RoHS, TSCA, and emerging PFAS regulations simultaneously. The same substance data is cross-referenced against Toyota's Prohibited, Restricted, and Declarable tables alongside EU and US framework requirements—eliminating duplicate collection campaigns and delivering a centralized compliance data backbone for all automotive substance obligations.
