US Parcel Sending
US Parcel Sending resumed from 22 September 2025
Australia Post has resumed postal services to the United States and its territories from Monday 22 September 2025. This follows the temporary suspension due to new US Customs rules requiring all duties and taxes to be prepaid.
What this means for Addition
- You do not need to "link" Addition with Zonos. The connection is between your Australia Post account and Zonos, not Addition.
- No changes are needed in Addition itself, we already pass HS Codes, Country of Origin, and item values to AusPost.
- The steps to create a shipping label for the US remain unchanged, process orders as you usually do.
Your checklist:
✅ Create a Zonos Verified Account you can register now for a Zonos account and link it to your Australia Post account Register for a Zonos account here.
✅ Ensure HS Codes, Country of Origin and product weights (per product) are set up correctly in Shopify so Addition can pass this information to AusPost. See our guide here
✅ If you previously removed the US from your Shopify shipping zones, re-add it so rates display again. If you want to stop rates showing, remove the US from your zones.
✅ (Optional) Add a banner for US customers
Explain that shipments to the US will include prepaid duties/taxes,
Creating Shipments in Addition
Nothing in the Create Shipment steps within Addition has changed. You will continue to create and pay for labels the same way you always have.
The key difference is what happens after you create a shipment to the US:
- Once your MyPost Business or eParcel account is connected to Zonos, Zonos will bill you directly for the duty and associated postal clearance fees.
- Zonos issues invoices within 24 hours of receiving the shipment data from AusPost (note: this can sometimes be a few days after you ship).
- You can view and download these invoices anytime in your Zonos Dashboard.
For any billing or duty-related questions, please contact Zonos directly on APsupport@zonos.com.
How does this affect shipping rate calculations with Addition?
Addition will not automatically calculate duties and taxes. Australia Post hasn’t updated their rates system to send us those amounts, so they won’t appear at the checkout.
At the checkout, Addition passes through the rates data that AusPost makes available. If Australia Post adds duties and taxes to their system, Addition will show them at checkout automatically however Australia Post have not updated their API's, so Addition can not show duties and taxes at the checkout.
Options to collect or charge US customers for duties and taxes:
- One option is enabling Shopify’s Duties & Import Taxes feature
- Other merchants choose to add a handling fee on top of Addition’s rates with custom rate rules (available on Pro plans or above)
- Some customers are building the duty and tax into their product pricing specifically for the US, and then manually updating the declared cost to the normal RRP when printing labels, so their import taxes aren't inflated.
How Shopify Duties & Import Taxes works
- Available on Basic, Grow, Advanced, and Plus plans.
- Enable it under Settings → Markets → Duties and Import Taxes.
- Shopify calculates duties using your HS codes and Country of Origin.
- Duties show as a separate line item at checkout, giving customers full landed cost clarity.
- Customers pay product + shipping + duties/taxes upfront.
- You, the merchant, receive the full amount and then lodge the shipment with AusPost.
- Shopify charges a 0.5% transaction fee on orders where duties are collected this way.
