Short answer: AUST L ("listed") medicines are lower-risk supplements the sponsor self-certifies against a fixed list of TGA-permitted ingredients and claims; AUST R ("registered") medicines are higher-risk or higher-claim products the TGA fully evaluates before sale. Most vitamins and supplements are AUST L — you only need AUST R to make stronger therapeutic (disease) claims or to use ingredients the listed pathway won't allow.
Both are entries on the Australian Register of Therapeutic Goods (ARTG) — almost every therapeutic good sold in Australia needs one. The code on the label (AUST L, AUST L(A), or AUST R) tells you which pathway the product went through, and that pathway decides what you can put in the product and what you can say about it. For the wider picture, see our guide to selling supplements into Australia.
What is an AUST L (listed) medicine?
A listed medicine (AUST L) is the pathway for the majority of low-risk supplements — most vitamins, minerals, and many herbal and complementary products. Its defining features:
- The sponsor self-certifies compliance; the TGA does not evaluate the product's efficacy before it goes on sale.
- It can contain only ingredients on the TGA's Permissible Ingredients Determination, often at specified dose limits.
- It can use only indications drawn from the TGA's pre-approved Permissible Indications list, and the sponsor must hold evidence to support each one.
The trade-off for that speed is hard limits: no ingredient off the list, no claim off the list, and no claims to treat, cure, or prevent a disease.
What is an AUST R (registered) medicine?
A registered medicine (AUST R) goes through full pre-market TGA evaluation of quality, safety, and efficacy before it can be sold. It's the pathway for higher-risk products and for stronger therapeutic claims — including claims to treat, prevent, or cure a disease, which are not available on the listed pathway at all. Most supplements never need it; AUST R is where you go when your intended claim, ingredient, or dose can't fit inside the listed framework.
What about AUST L(A) — assessed listed medicines?
There's a middle option. An assessed listed medicine (AUST L(A)) stays inside the listed framework, but the TGA has assessed the evidence behind its indication — allowing a "TGA assessed" claim on the label that an ordinary AUST L product can't make. It's a way to make a somewhat stronger, evidence-backed claim without the full cost of registration.
Which pathway does my product need?
Work through it in order:
- Are all your ingredients on the Permissible Ingredients list at permitted doses, and is your claim a permitted indication you can substantiate? → AUST L.
- Do you want a stronger, evidence-backed claim while staying listed? → AUST L(A).
- Do you need a disease/treatment claim, or an ingredient or dose the listed framework won't allow? → AUST R (or reformulate to fit AUST L).
Because the listed pathway is bounded by those two lists, most of the work happens at the formulation and claims stage — see what AU supplement brands are actually allowed to claim.
What an AUST L number actually means
A common misconception worth correcting: an AUST L number is not a TGA stamp of proven effectiveness. For listed medicines it means the sponsor certified compliance — not that the TGA tested the product. That's also why the claims you put on the label are policed so tightly after launch: the freedom of self-certification is balanced by enforced, post-market accountability.
