If you're shipping packages from Canada to the United States using Canada Post, you must now prepay duties before your parcel crosses the border.
The recommended method to prepay U.S. duties is through automatic billing through a Zonos Verified Account:
For ecommerce merchants in our Developer Program – integrating Canada Post shipping services into their ecommerce website or platform – our Delivery Duties Paid (DDP) solution is currently available to Canada Post commercial customers who either:
- Use a custom in-house shipping system integrated directly with Canada Post via our web services/APIs, or;
- Ship with their own Canada Post account (BYOA) through a third-party platform that has integrated with Zonos.
Getting started with a Zonos Verified account for automatic billing
With a Verified Account you can:
- Enable automatic billing from Zonos U.S. for duties and taxes
- Enable Zonos to collect duties from your business and remit them directly to U.S. Customs and Border Protection (CBP) on your behalf
- Access your U.S.-bound shipping labels in Snap Ship and Shipping manager immediately
- Access Zonos’s classify tool to generate accurate HS codes and duty rates (so you can build duty into your shipping or product costs), or integrate with Zonos’s ecommerce apps to enable Zonos to manage that for you at checkout.
How it works:
- You create a shipment as per your normal process
- Canada Post generates a Declaration ID
- Canada Post links the Declaration ID to your shipment's tracking number.
- Canada Post issues a shipping label (the Declaration ID confirms Zonos will collect and remit duties to CBP on your behalf).
- Using the tracking number and data shared from Canada Post, Zonos pays CBP directly for the shipment.
- Zonos invoices you for the duties associated with the tracking number.
How to set up a Verified Account
If you currently purchase U.S. shipping labels with an in-house custom development shipping system, you have the option to update your code of API call to Canada Post and sign up for a Verified Account with Zonos to obtain automatic billing.
What you need to do:
-
Sign up for a Zonos Account
-
Use this link to sign up for a Zonos account and obtain a Zonos agreement.
-
-
Create a Verified Account
- Click Create an account from the sign-up page.
- You can sign up quickly with Google or Apple or enter your email address and Zonos will send you a 6-digit verification code. Enter this code to finalize set up.
-
Add your business information
- Enter your business details, such as registration number and tax information
- Provide your estimated shipping volume (required for account verification)
-
Add a payment method
- Keep a valid payment method on file so Zonos can invoice you directly for duties.
-
To connect a payment method:
-
Navigate to dashboard.zonos.com
- Click on Settings
- Select Billing
- Click Add payment method
- Enter your credit card details and click Save
-
-
Locate your Account Key
- Once you have added a payment method and your account is approved, you'll receive a Zonos Account Key.
-
To locate your Zonos Account Key:
-
Navigate to dashboard.zonos.com
- Click on Settings
- Under Integrations, you will see your Zonos Account Key. This is a 13-character code that allows you to connect your Zonos account to your Canada Post account
- Copy the key and add it to your Canada Post account preferences.
-
-
Add your Zonos Account Key
If you’re using a custom in-house shipping system (via Canada Post web services/APIs):
- Your developer must include the Zonos Account Key in the API header when making calls to Canada Post.
- This enables Canada Post to generate and link a unique Declaration ID for each U.S-bound shipment.
- Example header format: “X-CPC-Zonos-Key=xxxxxxxxxxx”
- Estimated effort: Approximately 1.5 weeks (1 sprint with 2 developers and 1-2 QA resources)
If you’re shipping with your own Canada Post account (BYOA) through a third-party platform integrated with our Zonos DDP solution:
- Save your Zonos Account Key in your third-party platform settings.
-
Create a shipment
- Follow your existing process to generate a Canada Post US-bound shipping label
- A Declaration ID is created and attached to your shipments tracking number. The declaration ID is your payment of duties validation – ensuring Canada Post knows duties are covered, so your label can be issued without delay
-
Receive shipping label
- Canada Post will issue the shipping label because the declaration ID confirms Zonos will connect and remit duties to CBP on your behalf.
-
Proceed with Zonos Automatic Billing
- The system automatically processes payments from your stored method.
How billing works with a Verified Account
- Zonos collects duties for each shipment tied to your Verified Account.
- You are invoiced directly by Zonos.
- Zonos remits the duties to CBP on your behalf.
