Toyota TSZ0001G

Customer & Industry Requirements

Control Method for Substances of Environmental Concern

Toyota TSZ0001G Covers Prohibited, Restricted, and Declarable Substances Across Your Entire BOM. Can You Prove Compliance for Every Part?

Toyota TSZ0001G compliance requires substance-level tracking across every part, raw material, and accessory in your supply chain—with mandatory IMDS submissions and CAS-level reporting. The standard aligns with GADSL, EU ELV, REACH, and RoHS while adding Toyota-specific prohibitions and thresholds. Revisions can add new controlled substances at any time. IMDS data entry deadlines are non-negotiable.

Certivo automates Toyota TSZ0001G substance tracking from supplier declaration to OEM-ready evidence package.

Regulation Overview

• Jurisdiction: Global (OEM-specific standard issued by Toyota Motor Corporation, applied across its worldwide supply chain)
• Regulatory Body: Toyota Motor Corporation (TMC) — Engineering Data Control and Management Division
• Regulation Number: TSZ0001G (Class C — Engineering Standard, Confidential)
• Effective Date: First established September 2007 (revised periodically; current revision 15)
• Official Source: Distributed via Toyota Supplier Portal; not publicly available
• Key Threshold: Substance-specific; aligned with GADSL and ELV Directive limits

What is Toyota TSZ0001G?

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.

Key Components / Sub-Frameworks

• Obligation: Zero-content requirement; no use permitted unless specifically exempted
  • Prohibited Substances (Table 1): Substances banned from use in Toyota parts (e.g., asbestos, certain azo dyes, specific brominated flame retardants)
  • Obligation: Must remain below Toyota-specified limits aligned with ELV Directive thresholds
  • Restricted Substances (Table 2): Substances permitted only within defined thresholds (e.g., lead, cadmium, mercury, hexavalent chromium)
  • Obligation: Must be disclosed in IMDS with CAS numbers and concentration data
  • Declarable Substances (Table 3): Substances requiring reporting if present above threshold (aligned with GADSL)
  • Obligation: Exemptions carry conditions and expiration dates; must be pre-approved by TMC
  • Exempt Substances (Table 4): Specific applications where prohibited substances are temporarily permitted
  • Obligation: Testing per Toyota-approved methods; results documented and retained
  • Content Examination (Section 6): Methods for verifying SOC content in materials and parts
  • Obligation: Mandatory for all newly adopted parts; updates required on composition changes
  • IMDS Reporting: Material data entry into IMDS for all parts and materials

Key Compliance Requirements

Who Must Comply

• 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

• 0.1% (1,000 ppm): GADSL declarable substance reporting threshold in homogeneous material
• 0.01% (100 ppm): Cadmium threshold per ELV Directive (TSZ0001G Table 2)
• 0.1% (1,000 ppm): Lead, mercury, hexavalent chromium threshold per ELV (TSZ0001G Table 2)
• Zero content: Prohibited substances (Table 1)—no intentional addition permitted

Core Obligations

1. IMDS Data Entry: Submit full material composition at CAS number level for every part
   DEADLINE: Before Production Part Approval Process (PPAP)
2. Prohibited Substance Elimination: Verify zero content of Table 1 substances in all delivered parts
   DEADLINE: At time of supply; ongoing monitoring
3. Restricted Substance Compliance: Maintain Table 2 substances below Toyota-specified thresholds
   DEADLINE: At time of supply; per-lot verification where required
4. Declarable Substance Reporting: Disclose Table 3 and GADSL substances above threshold in IMDS
   DEADLINE: With every new or modified part submission
5. Revision Compliance: Update IMDS data and internal processes when TSZ0001G is revised
   DEADLINE: Within Toyota-specified timeline per revision notice

Frequently Asked Questions

1. 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.

2. 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.

3. How does Certivo track updates to TSZ0001G and GADSL?
   Certivo maintains continuous sync with GADSL updates—and monitors TSZ0001G revision notices.

4. 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.

5. 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.
