Direct answer: Align disclosed ingredients and concentration information with classification evidence.
Separate substances and mixtures
The information structure differs. Record product type before selecting the Section 3 disclosure workflow.
Use verified identifiers
Store chemical name, CAS number and other identifiers from reliable source documents, not search snippets.
Control concentration ranges
The range used for disclosure must remain compatible with the value or worst case used in hazard assessment.
Handle confidential information lawfully
Do not replace ingredient details with improvised secrecy wording. Apply the relevant Australian rules and preserve necessary hazard information.
Reconcile formula revisions
A formulation change should reopen classification and all affected SDS sections, not only the ingredient table.
Practical example
A surfactant grade changes from 30% to a 25–35% range. The team confirms active content, maps the classification input and checks whether the finished-product result changes before updating Section 3.
Release checklist
- Confirm substance or mixture
- Verify ingredient identifiers
- Map disclosed and assessed concentrations
- Review confidentiality basis
- Trigger impact review on change
Common mistakes
- Copying CAS numbers from an unverified website
- Using a range inconsistent with classification
- Updating composition without reassessing hazards
Frequently asked questions
Must every ingredient be listed?
Disclosure depends on applicable requirements and hazard relevance; verify the current Australian rules.
Can trade names replace chemical identity?
Not by default. Apply lawful identity and confidentiality provisions.
Should impurities be considered?
Yes, when they can affect product classification or required information.
Can ranges be used?
Use them only where permitted and keep the classification basis traceable.
