Executive Overview
The regulatory landscape for Safety Data Sheets (SDS) in Australia and New Zealand has undergone a complete transition to GHS Revision 7 (GHS 7). This shift represents a structural realignment of hazard classification, communication, and documentation across both jurisdictions, introducing region-specific deviations that must be explicitly addressed in SDS authoring.
From a compliance perspective, organisations operating across ANZ are now required to manage harmonised classification frameworks with non-harmonised implementation rules, creating a dual-layer complexity in SDS preparation.
1. Regulatory Convergence: Adoption of GHS Revision 7
Australia
Australia formally mandated GHS Revision 7 as of 1 January 2023, replacing the earlier GHS 3 framework. [safeworkau…lia.gov.au]
- All hazardous chemicals must be classified, labelled, and supported by SDS under GHS 7
- SDS updates are required even for legacy stock where labels remain under previous systems [safeworkau…lia.gov.au]
New Zealand
New Zealand aligned with GHS 7 through amendments to the Hazardous Substances Notices, with full compliance required by 30 April 2025. [epa.govt.nz]
- No extended sell-through provision applies after this date
- SDS, labelling, and packaging requirements now operate under a unified post-transition regime [epa.govt.nz]
2. Structural SDS Requirements: 16-Section Format
Both jurisdictions require strict adherence to the standardised 16-section SDS structure, including:
- Identification
- Hazard(s) identification
- Composition / information on ingredients
- First-aid measures
- Fire-fighting measures
- Accidental release measures
- Handling and storage
- Exposure controls / PPE
- Physical and chemical properties
- Stability and reactivity
- Toxicological information
- Ecological information
- Disposal considerations
- Transport information
- Regulatory information
- Other information
This structure is fully aligned with GHS and is mandatory for compliance in both Australia and New Zealand. [epa.govt.nz]
3. Key Technical Changes Introduced Under GHS 7
3.1 Updated Hazard Classification Framework
GHS 7 introduces new hazard classes and refined criteria, including:
- Desensitised explosives
- Pyrophoric gases
- Non-flammable aerosols
- Chemically unstable gases
- Clarified eye irritation subcategories (2A vs 2B) [safework.nsw.gov.au]
These changes directly impact Section 2 (Hazards Identification) and require reclassification of legacy formulations.
3.2 Revised Precautionary Statements
Precautionary statements have been standardised and rationalised, affecting:
- Risk communication clarity
- Wording consistency across SDS and labels
- Alignment between Sections 2, 4, 7, and 8
Australia explicitly requires updated phrasing consistent with GHS 7. [sdsmanager.com]
3.3 Mandatory SDS Review Cycles
Both jurisdictions enforce lifecycle control of SDS documentation:
- Minimum review interval: 5 years
- Immediate revision required upon:
- Reformulation
- Hazard reclassification
- New toxicological or ecological data

4. Australia vs New Zealand: Critical Divergences
Despite common adoption of GHS 7, there are material regional differences that must be captured at SDS level.
4.1 Hazard Building Blocks
| Parameter | Australia | New Zealand |
|---|---|---|
| Acute Toxicity Cat. 5 | Optional | Generally applied |
| Eye Irritation 2B | Optional | More structured classification |
| Environmental Hazards | Not mandatory | Expected / included in SDS |
4.2 Environmental Classification (Section 12)
- Australia: Aquatic toxicity classification is not mandatory under WHS
- New Zealand: Requires broader ecological endpoints, including:
- Aquatic toxicity
- Terrestrial toxicity (e.g. soil organisms)
This creates a critical divergence in Section 12 data requirements for export-ready SDS.
4.3 Cut-off Concentration Differences
- New Zealand adopts stricter cut-off thresholds for sensitisation (e.g. 0.1%)
- This may trigger classification where Australia does not
4.4 Localisation Requirements
Australia:
- SDS must include:
- Australian supplier details
- Australian emergency contact number
- Overseas SDS are non-compliant without localisation
New Zealand:
- Allows use of overseas SDS with NZ-specific data overlay
- Must comply with Safety Data Sheets Notice 2017
5. Legal Framework and Enforcement
Australia
- Governed under Work Health and Safety (WHS) Regulations
- Enforced by state regulators (e.g., SafeWork NSW)
New Zealand
- Governed by:
- Hazardous Substances and New Organisms Act (HSNO)
- Health and Safety at Work Act (HSWA)
- Safety Data Sheets Notice 2017
Failure to maintain compliant SDS may result in enforcement actions, particularly where SDS deficiencies impact worker safety or emergency response capability.
6. Operational Implications for SDS Authoring
From a technical standpoint, compliance now requires:
6.1 Dual-Jurisdiction SDS Strategy
- Single dataset → multiple jurisdiction outputs
- Rule-based classification layers (AU vs NZ)
6.2 Data Integrity Management
- Centralised substance database
- Version control and audit traceability
- Hazard classification reconciliation workflows
6.3 Export-Ready SDS Design
- Build SDS with maximum dataset coverage (NZ-level detail)
- Apply jurisdiction-specific filtering for AU release
7. Forward Outlook: Beyond GHS 7
The United Nations has released GHS Revision 11 (2025), introducing:
- New hazard classes (e.g. chemicals contributing to global warming)
- Updated classification criteria
- Revised precautionary communication framework
While not yet adopted in ANZ, these changes indicate future SDS expansion requirements, particularly in environmental hazard communication.
Conclusion
The transition to GHS 7 in Australia and New Zealand is not merely administrative—it represents a technical recalibration of hazard communication systems.
For organisations operating in manufacturing, formulation, and international distribution:
- SDS must be treated as controlled regulatory documents
- Authoring must incorporate jurisdictional logic
- Data governance is now central to compliance
