If you are importing a product and want it on an Australian retail shelf, you need a barcode that scans and a GTIN that is genuinely yours. This guide covers GS1 Australia membership versus cheap resold barcodes, what the big retailers actually require, how many barcodes you need across sizes and colours, and how to get them printed at the factory in China instead of hand-stickering cartons in a Newcastle warehouse.
Last updated: 9 September 2026
In short: If you want your imported product on a shelf at Coles, Woolworths, Bunnings or Chemist Warehouse, you need a barcode built on a GTIN registered to your own business — which in practice means a GS1 Australia membership, not a $10 barcode number bought off a random website. You need one unique barcode for every variant you sell (each size, colour and pack size), and the cheapest way to apply them is to have the factory in China or Vietnam print them straight onto your retail packaging, not sticker them by hand once the container lands in Newcastle.
Not legally — there is no Australian law that says a product must carry a barcode. But commercially, yes. Every major Australian retailer requires a scannable barcode with a GTIN (Global Trade Item Number) before they will list your product, because their entire inventory, pricing and supply chain system runs on it.
If you are only selling direct-to-consumer through your own Shopify store, you can genuinely skip barcodes for now. The moment you want to sell into retail, wholesale to a distributor, or use a third-party warehouse, you will need them.
These three terms get used interchangeably and it causes a lot of confusion, so here is the plain-English version.
A GTIN is the number itself — the unique identifier for your product. An EAN-13 is the 13-digit barcode symbol used across Australia, Europe and most of the world. A UPC-A is the 12-digit version used mainly in North America. Australian retailers expect EAN-13.
So when a buyer at Woolworths asks for your GTIN, and your factory asks for your EAN, they are asking about the same number in two different formats.
This is the decision that trips up most first-time importers, and getting it wrong can mean a rejected retailer application after you have already printed 5,000 boxes.
GS1 Australia is the only organisation that issues genuine, globally-unique GTINs licensed to your business name. Your company is listed as the brand owner in the global registry, which is exactly what retailers check.
Resold barcodes are numbers from old GS1 prefixes issued before 2002, split up and sold cheaply online. They will physically scan. But the registry still shows the original owner — not you — and most major Australian retailers reject them outright.
| Factor | GS1 Australia membership | Resold barcode |
|---|---|---|
| Cost | Annual fee, scaled to turnover and number of barcodes | Often under $50 one-off |
| Registered to your business | Yes | No — shows the original owner |
| Accepted by Coles, Woolworths, Bunnings | Yes | Generally no |
| Accepted for Amazon AU | Yes | Risky — Amazon verifies against the GS1 database |
| Right for you if | You want retail, wholesale or marketplace distribution | You are only ever selling on your own website |
Our honest take after helping 300+ Australian businesses get products to market: if there is any chance you will pitch a retailer or scale on Amazon, pay for the GS1 membership. The saving on a resold barcode is trivial compared to reprinting packaging.
One unique GTIN for every distinct sellable variant. This is where importers underestimate their barcode count badly.
Take a Newcastle homewares brand importing ceramic mugs from China. If the mug comes in three colours and two sizes, that is six retail GTINs — not one. Add a two-pack gift set and that is a seventh. Then the outer shipping carton needs its own separate code (a GS1-128 or ITF-14) so the warehouse can scan the case without opening it.
Work your variant count out before you buy your GS1 barcode allocation, because moving up a tier later is more expensive and more painful than starting at the right one.
Beyond the GTIN itself, most of the big Australian retailers will want your barcode to meet some practical standards. In our experience the recurring requirements are these.
An EAN-13 at no less than 80% of nominal magnification, with the mandatory quiet zones (the blank margins either side) intact. Squashing a barcode to fit a small label is the single most common scanning failure we see.
Dark bars on a light background. Not white-on-navy, not red bars, and never printed over a busy pattern or a gradient. Red is effectively invisible to many older laser scanners.
A separate ITF-14 or GS1-128 on the shipping carton, with the quantity clearly stated.
Dimensions, weight, ingredients or materials, and images all keyed against the GTIN. GS1 Australia's National Product Catalogue is what most of the majors pull from.
Have the factory print it. Every time you can.
Getting your barcode printed directly onto retail packaging during production typically costs you almost nothing — it is just artwork on a box that is being printed anyway. Hand-applying barcode stickers to a few thousand units in an Australian warehouse costs real labour money, looks second-rate on shelf, and stickers lift in the heat.
Here is a rough comparison for a 3,000-unit order landed in Newcastle:
| Approach | Typical cost per unit (AUD) | Notes |
|---|---|---|
| Barcode printed on retail packaging at the factory | Effectively $0 (artwork change) | Cleanest result; must be locked in before artwork sign-off |
| Factory applies pre-printed labels | ~$0.05–$0.15 | Good fallback if packaging is already printed |
| Hand-stickered in an Australian warehouse or 3PL | ~$0.35–$0.90 | Labour plus label cost; adds handling time |
On 3,000 units, that is the difference between roughly nothing and up to $2,700. Send your barcode artwork to the factory as a vector EPS or AI file at the correct magnification, and always ask for it on your golden sample so you can physically scan it before mass production starts.
Approving packaging artwork with a stretched or shrunk barcode. Letting the factory substitute a low-resolution JPEG of your barcode instead of the vector file. Reusing one GTIN across multiple colours to save money — retailers will catch it. Forgetting the carton-level code entirely, which stops your goods dead at a 3PL's inbound dock. And printing the barcode on a curved surface without allowing for distortion.
All five are cheap to prevent at artwork stage and expensive to fix once a container has shipped. This is exactly the kind of detail a properly built tech pack is meant to capture.
GS1 Australia charges an annual licence fee based on how many barcode numbers you need and your business turnover, with the smallest tiers aimed at start-ups and single-product businesses. Check current pricing directly with GS1 Australia, as fee tiers are reviewed periodically.
No. Every variant a customer can buy separately needs its own GTIN — that includes each size, each colour and each multi-pack. Sharing one number across variants breaks retailer inventory systems and will usually get your listing rejected.
It will probably scan, but it will almost certainly fail their supplier onboarding, because the GS1 registry will show a different company as the brand owner. The major Australian retailers verify brand ownership against the GS1 database.
In most categories yes, and Amazon checks your GTIN against GS1's database. Amazon has actively cracked down on resold barcodes, so a genuine GS1-issued GTIN is the safe route if marketplace selling is part of your plan.
Some will offer to, and you should decline. A barcode issued under your supplier's GS1 prefix identifies them as the brand owner, which means you do not control your own product identity and cannot easily change factories later. Own your GTINs.
We have sourced more than 20,000 products for 300+ happy Australian clients, with average savings of around 77%, and we have bilingual teams on the ground in China and Vietnam plus offices in five countries. Practically, that means we brief your factory on barcode artwork, check the printed barcode on your pre-production sample, and make sure your carton markings are right before anything ships — so your goods clear a retailer's or 3PL's inbound requirements first time.
Getting ready for retail? Our guides on packaging and labelling requirements when importing to Australia and country of origin labelling rules cover the other two things you must get right before you sign off artwork. If you are working out your true per-unit numbers, start with landed cost, and see our warehousing and 3PL service if you need somewhere for the stock to go.
Give us a bell and we will make sure your next order arrives retail-ready.
