When to Re-Categorise a Repeat AICIS Introduction

A maker asked us recently whether they needed to redo their AICIS categorisation for a product they'd been selling for two years, since nothing in the formula had changed. Fair question, and the honest answer is that the formula not changing doesn't automatically mean the categorisation is still correct. AICIS categorisation depends on more than the ingredients themselves.

Categorisation is a snapshot, not a title deed

Australia doesn't run cosmetics through a per-product notification system the way Canada or the EU do. Instead, AICIS treats cosmetic ingredients as industrial chemicals and works through an Inventory plus a set of introduction categories, which determine what obligations apply to bringing a chemical into Australia. The category you land in depends on factors like the chemical's identity, the volume you're introducing, and how it's going to be used, not purely on what the ingredient is.

That means the same ingredient, in the same formula, can sit in a different category depending on circumstances that have nothing to do with the recipe. This is the part people miss when they treat categorisation like a one-time form they filed and can forget about.

Situations that should trigger a fresh look

• Volume growth. If your introduction volume crosses a threshold relevant to your category, because sales took off or you're now importing in bulk rather than small batches, the category that applied at low volume may not still apply.
• Formula changes. Any reformulation that changes the concentration of a chemical, swaps a supplier's version of an ingredient with a different specification, or introduces a new substance entirely is a new introduction decision, not an amendment to the old one.
• New supplier, same INCI name. Two suppliers can both sell something you'd both call the same INCI name, but the actual substance, including impurities, particle size, or manufacturing process, isn't guaranteed to be identical. AICIS categorisation is chemical-specific, so a supplier switch is worth re-checking even if your label doesn't change at all.
• Change in end use. Repurposing an ingredient introduced for one product type into a different product category, especially anything that shifts toward higher exposure use, can change the risk profile the categorisation was based on.
• New market or export activity. If you start manufacturing in Australia versus importing, or your business structure around who is legally "introducing" the chemical changes, that can also affect which category applies.

What re-categorising actually involves

This isn't about resubmitting a full application every time something shifts slightly. It's about deliberately pausing and asking whether the facts that determined your original category still hold. In practice that means:

1. Pulling your original categorisation reasoning, if you documented it (you should have).
2. Comparing the current volume, supplier specification, and use case against what was true when you first categorised.
3. Re-running the categorisation logic against AICIS's current framework if anything material has changed.
4. Keeping a record of the re-check even if the conclusion is "no change needed." That record is what protects you later if anyone asks why you believed your categorisation was still valid.

Why this gets skipped

Small makers usually treat regulatory categorisation the way they'd treat a business license, something you get once and file away. AICIS's model is built around the chemical and its introduction circumstances, which is a moving target by design. It's not a flaw in the system, it's just a different shape of obligation than a lot of makers are used to from other markets, and it rewards checking in periodically rather than assuming permanence.

If your growth is mostly happening on the Canadian side right now, Cosmetic Comply already handles the Cosmetic Notification Form process end to end, including catching when a supplier swap changes an ingredient's real concentration in your finished product. Australian support is on the roadmap, and the same instinct applies there: any time your formula, supplier, or volume shifts, it's worth a fresh look rather than an assumption.
