When creating international shipments with your AusPost eParcel Contract, you may see either a CN22 or CN23 label.
Do I need to choose the label type?
No — you don’t need to select this yourself.
Australia Post will automatically generate the correct label based on your shipment details when you create your label in ReadyToShip.
CN22 label
A CN22 is an A6 customs declaration label used for smaller, lower-value shipments.
Your shipment must:
Weigh under 2kg (or under 5kg for the US)
Have a total value under A$500
Have combined dimensions under 90cm (L + W + D)
Have no single side longer than 60cm
Supported services:
International Standard (no signature): Selected countries only
International Express: All countries except China
If your shipment doesn’t meet these requirements, a CN23 label will be used instead.
CN23 label
A CN23 label is used for larger or higher-value shipments.
Your shipment will use CN23 if it:
Weighs 2kg – 20kg (5kg – 20kg for the US)
Has a maximum length of 105cm
Does not exceed 140cm girth
(Girth = (width + height) × 2)
Label printing options
Label formats are set in your Carrier Connection → Printer Settings.
You can only select one label format at a time.
If you’re using a thermal printer, select:
A6 (1 per page)
CN22 formats
A4 page: 4 × A6 labels per page
Thermal: 1 × A6 label
CN23 formats
A4 page: 1 × A5 label
A4 page: 4 × A6 labels per page (ideal for label sheets)
