A GTIN exemption is permission from Amazon to list a product without a Global Trade Item Number. On Amazon.com.au most products need a GTIN (UPC, EAN, JAN or ISBN); you get one from GS1 Australia or request an exemption in Seller Central. The criteria and the exact steps are published inside Seller Central, which is not public, so check them there before you build a launch plan around an exemption. Keep photos of the product and packaging ready, because Seller Central may ask for them when you apply. For what a GTIN is, see GTIN.
When might you not need a GTIN or an exemption?
Amazon may match your product to an existing listing, so no product ID may be needed. That is common when you resell a branded product already in the catalogue. Branded products need ownership or reseller authorisation. Third-party guides say exemptions mostly suit private label, handmade and bundled products, but Amazon has not confirmed this on a public page.
What do you need before you apply?
Prepare what you can show: the brand name, clear photos of the product and packaging without a barcode, and a description. The exact evidence Amazon asks for in Australia is not published publicly. Some categories need prior approval, grocery being named, and some products cannot be listed; see Amazon Australia category approval and the walk-through in Amazon Australia GTIN exemption.
Why buy barcodes anyway?
An exemption works only on Amazon. If you will sell in physical stores, or want to protect a brand, buy barcodes from GS1 Australia and use them everywhere. GS1 Australia sets its own pricing, so check its site and compare it with the cost of lost sales if a listing stalls. Buying a small block of barcodes once is often cheaper than repeating exemption requests for every new variation. Barcodes are also a good fit with a brand you protect with an IP Australia trade mark, which Brand Registry asks for.
Barcodes matter for fulfilment too. Stock you send into Amazon's network, including for MCF, must be identifiable, and unplanned prep and labelling services are charged when stock arrives unprepared or unlabelled.
What an exemption does not cover
It does not cover legal compliance. Electrical goods still need the RCM where it applies, and the Australian Consumer Law applies regardless of your identifier. Do not add a made-up barcode to a product; the product guide says to get a GTIN or request an exemption.
