Step 0: Introductions that are in the listed category

Learn about our introduction categories in 'before you start categorising your introduction'.

Start by searching our Inventory

The Australian Inventory of Industrial Chemicals (Inventory) is an online database of industrial chemicals that are being manufactured or imported into Australia. Start by checking whether your chemical is listed on the Inventory.

If you have a mixture or product that contains more than one chemical, you must search for each one separately.

If you know your chemical's identity

Search the Inventory using your chemical's CAS number. If you don't know the CAS number or the chemical does not have an assigned CAS number, search the Inventory using the chemical's CAS name (using the keyword search).

Note: Some common names for chemicals are on the Inventory but your results will most likely be a very broad list of candidate chemicals.

If you don't know your chemical's identity

Ask your chemical identity holder (for example, your supplier) to search the Inventory for you. If they find the chemical on the Inventory, you should ask them to tell you if there are any terms or conditions described on the Inventory listing for your chemical.

Search the Inventory

No search results or too many results

First, check if it is because of one of these reasons:

  • You're searching a trade name, INCI name or product name - we recommend that you search using the chemical's CAS number.
  • You have entered an outdated CAS number. Sometimes CAS replaces a chemical’s CAS number with a new one, so you need to make sure that you’re using the updated CAS number.
  • You entered an incorrect CAS number or it doesn’t match the CAS number format. For example you may have added a space between the numbers or hyphens.
  • It doesn’t need to be listed because it meets our definition of a naturally occurring chemical. This means that if a chemical meets the naturally-occurring definition, you don't need to search for this chemical on the Inventory.
  • It’s a mixture (such as an alloy or hydrate) – the Inventory only contains names of chemicals, not mixtures.
  • It's listed on the Inventory but the CAS name and CAS number are protected as confidential business information (CBI). You can ask us to check if your chemical is confidentially listed on the Inventory.

Trade names, product names and INCI names

The Inventory is a database of chemicals, not products, mixtures or formulations. Therefore it does not contain product names, trade or marketing names and rarely contains INCI or common chemical names. We recommend finding a CAS number or CAS name for each chemical that you want to search. For example:

Search using the CAS number or name

Don’t search using trade or common names

107-21-1 / 1,2-Ethanediol
57-55-6 / 1,2-Propanediol
144-55-8 / Carbonic acid, monosodium salt Baking soda
77-92-9 / 1,2,3-Propanetricarboxylic acid, 2-hydroxy- Citric acid
9005-25-8 / Starch Corn starch
7487-88-9 / Sulfuric acid magnesium salt (1:1) Epsom salt
56-81-5 / 1,2,3-Propanetriol Glycerine
8000-28-0 / Essential oils, lavender Lavender oil
13463-67-7 / Titanium oxide (TiO2) Liquid paper
1310-73-2 / Sodium hydroxide (Na(OH)) Lye
68917-75-9 / Oils, wintergreen Wintergreen oil

Important: These CAS numbers are examples only. It is the introducer’s responsibility to correctly identify and know the chemistry of their introductions.

Naturally occurring chemicals

Introductions of naturally occurring chemicals do not need to be listed on the Inventory. You can import or manufacture naturally occurring chemicals without telling us, as long as they meet our definition of 'naturally occurring'.


A mixture contains 2 or more component chemicals that don’t react. You need to search the Inventory for each component chemical that make up the mixture, not the mixture itself. You can import or manufacture the mixture as long as their component chemicals are on the Inventory and you follow the regulatory obligations.

CAS numbers

You can check if you have an up-to-date CAS number for your chemical by searching chemical databases such as ChemIDPlus and SciFinder-n.

If you find your chemical on the Inventory

If you get a match, click on the link to view the chemical identity information and any regulatory obligations associated with that chemical. Take note of the information you see on the listing page and see the descriptions below to find out what to do next.

If your chemical is on the Inventory without specified regulatory obligations

This is when the chemical's 'Inventory terms of listing' only describes chemical identity information like the CAS name and CAS number and does not specify any requirements, conditions or a ‘defined scope of assessment’.

Your introduction is categorised as listed.  Skip to 'Your obligations after categorisation'.


If your chemical is on the Inventory with a specific information requirement

Your introduction is categorised as listed but you must submit information about your introduction under certain circumstances. Skip to 'Your obligations after categorisation' to learn more.

If your chemical is on the Inventory with a defined scope of assessment

Icon of a target scope
If your introduction is within the parameters of the defined scope of assessment, then your introduction is categorised as listed. Skip to 'Your obligations after categorisation'.
If your introduction is outside the parameters of the defined scope of assessment, you must do one of the following before you can introduce the chemical:

If your chemical is on the Inventory with a condition of introduction or use

Icon of a page with text spelling 'conditions' and tick and cross symbols
If you plan to introduce the chemical within the boundaries of the specified conditions, then your introduction is categorised as listed. Skip to 'Your obligations after categorisation'.
If your introduction does not meet the conditions, you cannot introduce the chemical unless you submit an application and receive approval. Next step: apply to vary the Inventory terms of listing (fee applies).

If your chemical is not on the Inventory

Decorative image only
If your chemical is not on the Inventory and you have confirmed that it isn't on the list under the heading 'No search results or too many results' then your introduction is not in the listed category. Proceed to Step 1: Introductions that cannot be exempted or reported.
