​
Prerequisites for International Shipping

  • Valid Australia Post account with international shipping enabled
  • Product information including HS codes and country of origin (these are prefilled from your Shopify product details when available—see HS code and country of origin below)
  • Export documentation for high-value shipments
  • Compliance knowledge for destination country requirements

Customs Declarations

​
Required Information

For every international shipment, you must provide:

HS Codes

Harmonized System classification codes for each item. When you create international labels, HS codes are prefilled from your Shopify product details (variant inventory item’s Harmonized System code) when available—you can edit them as needed.

Item Descriptions

Detailed descriptions of goods being shipped

Country of Origin

Where the goods were manufactured or produced. Country of origin is prefilled from your Shopify product details (variant inventory item’s country of origin) when available—you can change it per item if needed.

Export Reason

Purpose of export (sale, gift, return, other)

​
HS Code and Country of Origin from Shopify

The app automatically prefills HS code and country of origin for each line item from your Shopify product/variant data when that information is set in Shopify (inventory item’s Harmonized System code and country of origin). This reduces data entry and helps keep customs declarations consistent. You can still edit or add values when creating a label. For best results, maintain HS codes and country of origin on your products in Shopify. Learn how to add HS codes in Shopify: Add HS codes for international shipping.

​
HS Code Management

HS (Harmonized System) codes are international classification codes. The app prefills HS codes from your Shopify product details (each variant’s inventory item Harmonized System code) when you create international labels—research and add codes in Shopify for products you ship internationally to streamline label creation. See Shopify’s guide to adding HS codes for step-by-step instructions.
  • Product databases: Use online HS code lookup tools - Supplier information: Check with your product suppliers - Customs websites: Official government resources - Industry guides: Sector-specific classification guides
  • 6-10 digits: Most countries use 6-digit codes, some require 8-10 - Format: XXXX.XX.XX (e.g., 1234.56.78) - Specificity: More digits = more specific classification
  • Electronics: 8517.12.00 (Mobile phones) - Clothing: 6203.42.40 (Men’s trousers) - Books: 4901.99.00 (Printed books) - Jewelry: 7113.19.50 (Precious metal jewelry)

​
Export Declaration Numbers (EDN)

For shipments over certain values, you need an Export Declaration Number:
EDN is mandatory for shipments over $2,000 AUD in value.
When EDN is required:
  • Shipments valued over $2,000 AUD
  • Certain restricted or controlled goods
  • Destination country requirements
How to obtain EDN:
  1. Register with Australian Border Force
  2. Complete export declaration online
  3. Receive EDN for your shipment
  4. Enter EDN in the app when creating labels

​
Setting Importer Reference via Shipping Rules

You can automatically set the importer reference number for international shipments using Shipping Rules. When an order matches a rule that has the Importer reference number action, the app applies that value to the customs declaration for the label—useful when you routinely use a fixed importer reference (e.g. your company or client reference) for certain destinations or order types. How to set it:
  1. Go to Shipping Rules in the app and create or edit a rule.
  2. Add a condition that targets international orders (e.g. Destination country not equals Australia).
  3. In Actions, add Importer reference number and enter your reference (max 40 characters).
  4. Save and enable the rule.
When you create an international label for an order that matches this rule, the importer reference will be prefilled on the customs declaration. Shipping rule action: Importer reference number for international orders
