International Australia Post labels and customs from Shopify
Short answer
Add each product's HS code and country of origin in Shopify, and All In One Australia Post Ship uses them on the customs declaration. Watch for three common blockers: the 20-line customs limit, the SKU that EU parcels need, and the Zonos Verified Account Australia Post requires for US parcels.
International labels need more information than domestic ones, and most failures come from missing customs details. Set them up once in Shopify and later orders pick them up.

Add customs details in Shopify
Open Products, then the variant, then Shipping, then Customs information. Add the:
- HS code, which classifies the product for customs
- Country of origin, where the product was made
If Shopify has a code for the destination country, such as a 10-digit US code, the app uses that one. A blank country of origin defaults to Australia, so check products that were made elsewhere.
The 20-line customs limit
Customs declarations are limited to 20 lines. The app sends each line item as a customs line, so an order with more than 20 line items can’t get an international label in the app. For those orders, create the shipment directly in MyPost Business.
Sending to the EU
Since 22 October 2026, Australia Post needs each item’s SKU on parcels to the 27 EU member states, except gifts and documents. The app sends the Shopify SKU automatically, or a product ID when a product has no SKU. Add SKUs in Shopify if you want your own codes shown.
Sending to the US
Australia Post may refuse a US parcel with: “To send to the US, you need a Zonos Verified Account.” Set up Zonos in MyPost Business, then try again. If your app window still shows the old message, reload the page first.
Reason for export
If you see “The classification type GIFT is not available for your account” or “SAMPLE is not valid for the product”, choose another reason that truthfully fits, such as Sale of goods.
Label size
International labels print on A6 or A4, one per page. See label sizes.
Common questions
Does partial fulfilment reduce the customs lines?
No. The app sends the order's line items as customs lines, so shipping only part of an order doesn't get it under 20 lines.
What does the Standard Large service mean?
It's Australia Post's name for one of its international services. There isn't a larger version to choose.
Can I mark a sale as a gift to reduce the customs value?
No. Declare the real reason for export. Calling a sale a gift is a false customs declaration.
