Direct answer: Create traceable GHS 7 decisions for each physical and health hazard endpoint.
Define the classified object
Record whether the decision concerns a substance, grade, mixture or article and capture physical form and composition.
Prioritise relevant evidence
Use product tests, reliable substance data, supplier evidence and applicable mixture methods with clear source dates.
Assess endpoint by endpoint
Keep flammability, corrosion, acute toxicity and other decisions separate so evidence and uncertainty remain visible.
Document non-classification
A ‘not classified’ result still needs a rule, evidence and reviewer rather than an empty field.
Generate communication after approval
Only approved endpoint decisions should populate Section 2 and the label.
Practical example
Two products share a CAS-listed ingredient but differ in concentration and physical form. Their Australian classifications are assessed separately rather than inherited from the ingredient name.
Release checklist
- Define exact product
- Collect dated evidence
- Assess each endpoint
- Record uncertainty and rationale
- Approve before generating output
Common mistakes
- Classifying a mixture from its product name
- Treating every supplier result as equivalent
- Leaving non-classification undocumented
Frequently asked questions
Does a CAS number determine classification?
No. It identifies a substance context; product composition, form and evidence still matter.
Can test data override calculation?
The applicable GHS 7 criteria and evidence hierarchy must be reviewed for the endpoint.
Should every endpoint have a record?
Yes, including justified non-classification or data-gap status.
Can classification be reused?
Only after confirming the product, grade, formulation and regulatory basis match.
